Abstract: Cycling is a popular sport which is preferred by all age groups all around the world. As it is
an active sport, it requires special types of clothing to provide comfort to the wearer. In spite being
a healthy activity, cycling can result with acute or chronic injuries. In this study, an extensive survey
was conducted to the cyclists in order to reveal their preferences of cycling clothes, their requirements,
their accidental experiences and safety needs. By considering the survey results, optional designs
of a more protective and functional cycling top wear were outlined. In order to avoid from acute injuries
which were stated to be in the shoulder and arm areas the most, a para-aramid and spacer/silicon foam
supported design was proposed. Also, the visibility was enhanced by the implementation of active
lightening on the front and back sides of the clothing.
Keywords: cycling top wear, survey study, protective clothing, functional clothing, clothing design.
Recently, there has been an increasing interest
in sports because of the desire to be healthier,
to relieve stress and to create a lifestyle. Cycling is
one of the most popular sports as it appeals to all
age groups, promotes general good health, does not
require high costs and can be made in all seasons.
In addition of being a sport, cycling is a means for
a cheap, healthy and a green transportation [1].
Cycling sports can serve to both recreational and
professional purposes. The cycling types namely,
road cycling, cyclo-cross and mountain biking belong
to professional cycling pursuits [1]. They can cover
various time intervals and different levels
of performance. Therefore, cycling may need
different clothes with special properties. Some
of the selection parameters of cycling clothes are
the price, appearance, size, fit, design, availability
and quality [2]. Appearance and fit can be the most
important selection parameters for recreational
cyclists. But, especially for professional cycling,
functional properties and comfort properties are
of higher importance [2-4]. Some of the functional
and comfort properties expected from cycling clothes
are moisture absorbency, moisture management,
fast drying, breathability, lightness, stretchability, heat
preservation, resistance to sunlight, high visibility etc.
[2, 5, 6].
By considering various requirements from the cycling
clothes, many studies were done in the literature
in particular research areas. Some studies searched
the fit of cycling clothes. For example; Vuruskan and
Ashdown [7] built half scale dress forms for active
body positions of cyclists by capturing 3D body
positions using body scanners. In the further study,
they produced 3D printed active forms which were
equipped with pressure sensors to measure the fit
of cycling shorts [3]. Liu et al [4] determined
the digital clothing pressure for static condition and
dynamic cycling condition by using software and
optimized the design of a cycling t-shirt.
Compressional properties of compressive cycling
clothes were also studied in the literature.
Leoz-Abaurrea and Aguado-Jimenez [8] investigated
the effect of upper body compression garments
on the cardiovascular and thermoregulatory strain
of cyclists those cycled in hot environment. Brighenti
et al [9] compared the performance effect of a new
type of whole body compression garment with
ordinary summer cycling cloth in hot climate (32°C).
Hintzy et al [10] studied the effects of thigh
compression shorts on muscle activity and soft tissue
vibration during cycling. Another study field
on cycling clothes was the visibility as it could
provide protection against cycling accidents.
Lahrmann et al [11] made an extensive study
in which the effect of bright colored cycling wear
on the number of cycling accidents was searched.
Lee [12] designed a cycling jacket incorporating solar
powered LED (light emitting diodes) sensor lights
in order to improve visibility. Koo and Huang [13]
tested different configurations of flashing LEDs
on cycling clothes to the psychological perception
of drivers. Kgatuke et al [14] developed a cycling
jacket integrated with LEDs. As smart solutions
Fibres and Textiles 28(1), 2021 32
to cycling clothes; Paiva et al [15] designed and
produced a smart cycling cloth that was able to
measure the heart beats of cyclists by means
of different materials such as textile and silicon
based electrodes. Qiu and Hu [16] proposed and
defined the design of a smart cycling top wear that
could measure the heart rate, body temperature and
moisture of the cyclist by implementing electronic
devices to the clothing.
In addition to these researches, there are rare other
studies on cycling clothes. As an example,
Oglakcıoglu et al [6] investigated the thermal comfort
properties of sewn parts of cycling clothes. Teyeme
et al [2] searched the pains/injuries of 94 cyclists,
which occurred during or after cycling. Vuruskan [17]
conducted a cross-national survey study for cycling
clothes in which 25 cyclists from Turkey and
25 cyclists from United States were included.
In the survey, customers’ perspectives on fit and
customization were questioned. Teyeme et al [18]
organized some wear trials for 4 kinds of cycling
wear in order to determine their comfort properties.
Kwon and Kim [19] developed a cycling top wear with
the combination of 3 fabrics in order to response
different sweating rates and compression needs.
Also, there are other studies in the literature;
conducted to evaluate the comfort properties
of knitted fabrics/garments those could be useful
for the design of cycling clothes. For example,
Suganthi and Senthilkumar [20] examined
the moisture management properties of 7 bilayer
knitted fabrics composed of different raw materials.
Ozkan and Kaplangiray [21] investigated the thermal
comfort of 7 knitted fabrics that could be used
for athletes’ wear. Abreu et al [22] determined
the thermal comfort properties of 3 knitted shirts that
were suitable for sportswear. Wong and Yeung [23]
organized wear trials for 8 knitted sportswear in order
to evaluate their comfort properties.
The aim of this study was to create a design idea
of a more functional and protective cycling clothing,
by considering the user behaviours, experiences and
requirements. For this purpose, firstly, an extensive
survey was conducted to 500 cyclists in order
to collect required information related to their current
cycling clothes. In addition, information was collected
about their accidental experiences in order to add
protective segments on the clothing.
This study differs from the literature by collecting
detailed information on cycling clothes about seam
problems, visibility preferences, model preferences,
comfort requirements and accidental issues and, as
all this information was used to create smart
solutions for cyclists.
The survey containing 38 questions/statements were
constructed according to an 8-step process [24].
According to this methodology, firstly, it was
determined what the new information would be
obtained from the survey. Then the most appropriate
survey type and sampling method was determined.
In the next steps, useful questions were constructed
and conducted to cyclists via a plan. Then the data
was analyzed and presented as tables, figures and
mean values. Both the questions and data were
controlled several times to avoid from errors.
The final survey form can be found in the Appendix.
In the survey, information about the usage behaviors,
model preferences, protection and visibility
requirements, seam problems and accident
experiences were collected in addition to some
demographical information.
The survey was firstly tested on a small cyclist group
to get feedbacks about the understandability
of the questions. After revisions, the last version
of the survey was conducted to cyclists utilizing
Google Documents, between the dates of June-
December 2019. Convenience sampling method was
used as it was the least expensive and time
consuming method [25]. According to the literature
[26, 27], at least 384 participants should be taken
where the target population is higher than 10 million.
Therefore, in this study, data collection was
completed when the total number of respondents
reached 500 cyclists. All of the questions were
answered by the respondents. The survey was
conducted to cyclists in Turkey, including all
geographical regions.
In the survey; Likert scale questions (in matrix form),
multiple choice questions, Yes/No type questions
and open-ended questions were used. Frequency
values, means and plots of responses were
compared to evaluate the results.

For the clothing design, a user-centered approach
was adopted for this work [28, 29]. As the design
methodology, first 3 steps of the clothing design and
development framework that was employed
by Rajamanicham, Park and Jayaraman was utilized
[30]. For this purpose, firstly, the requirements of our
target group were detected by the aforementioned
survey study. Then the design properties were
formed. At the next step, suitable materials were
selected. Details of the adapted design methodology
for cycling wear design are summarized in Table 1.
By using these principles, 2D flats were created
containing alternatives. The cycling clothes were
designed by using Designer 9 (Gerber, Artworks
Expert). Patchwork design [31] of 4 kinds of fabrics
was performed, including the usage of elastane
containing polyester fabric, aramid fabric, meshed
fabric and supportive spacer fabric, in order
to enhance protection and comfort properties
of the final design.
3.1 Demographics and cycling behaviours
Age and gender information of respondents were
taken as demographics. The age range
of the respondents was 16-65 years old (mean: 34.5,
st. dev.: 11.3) (Figure 1a).
The study covered a broad range of ages from 16 to
65. Therefore, the standard deviation was high. 87%
of the respondents were male where 13%
of respondents were female (Figure 1b). Also, 53%
of respondents were licensed cyclists.
Cycling behaviours of respondents are given
in Figure 2. According to Figure 2a, respondents
used at least one of the 5 bicycle types. At least
30 respondents were taken from each bicycle types.
40% of respondents had been cycling for 7 years
or more (Figure 2b). They trained cycling for different
time intervals, weekly (Figure 2c).
71% of respondents cycled 2-4 h, non-stopping
(Figure 2d). From all these behavioural information,
it can be concluded that, respondents were well
experienced on cycling.
3.2 Accidents related to cycling
Cycling injuries can be classified into 3 types,
namely; traumatic, bicycle contact and overuse
(chronic) injuries [32]. Traumatic injuries can be
sourced from crashes with other vehicles or bicycles,
from potholes, rocks, dogs, operator errors or by
mechanical reasons [33]. In this study, traumatic
injuries had been explored to reveal if any protection
could be provided by altering cycling clothes’ design
and materials.

Figure 2 Cycling behaviours of respondents
Fibres and Textiles 28(1), 2021 34
Figure 3 Injury areas of cyclists
According to the results, 59% of respondents stated
that they experienced accidents during cycling.
The injured areas of the body were marked
in Figure 3a.
The areas such as 2, 3, 4, 5, 15, 16 and 17 also
covered “y” axis symmetry of the body. In Figure 3b,
frequencies of the injured areas are given. According
to results, most injured area was the hands area
(26% of respondents) and it was followed by knees
area (23.6%). Also almost 20% of the respondents
were injured in the shoulders and lower arms area.
The total number of upper arm (3), lower arm (4) and
elbow (16) injuries was 240. The least injured areas
were abdominals, chests and necks.
3.3 Protection, visuality and comfort related
requirements from cycling clothes
Respondents mostly cycled in the summer season
and under intense sunlight (Figure 4a). Nevertheless,
458 of them at least rarely cycled in the dark weather
(Likert mean: 3.2). Also, 93% of respondents stated
that they needed high visibility in the dark
(Figure 4b). 464 cyclists increased their visibility
by using bicycle lights and also 457 of them
enhanced the visibility by using clothing (Figure 4c).
Among the clothing visibility enhancements, using
reflective fabrics was the most employed method
(Figure 4d). Higher visibility can protect the cyclists
from accidents; therefore, the safety of the cyclists
can be enhanced [11, 34-36].
Figure 4 Visuality of cycling clothes
Fibres and Textiles 28(1), 2021 35
Figure 5 Functional options in cycling
Figure 6 Comfort needs of cyclists
59% of respondents used heart rate sensors during
cycling (Figure 5a). Mostly, chest type sensors were
used by respondents (Figure 5b). Also, 56%
of respondents thought that compressing products
could impact their performance (Figure 5c).
Comfort related requirements from cycling clothes
were also questioned in the survey and the results
are shown in Figure 6. Likert mean values for being
thin, lightweight, air permeable, moisture permeable,
fast drying and thermal insulator were higher than
4.4. The mostly desired comfort property of cycling
clothing was drying fast (Likert mean: 4.8). It was
followed by being lightweight, air permeable and
moisture permeable at high levels (Likert mean: 4.7).
In addition, comfort approaches of female and male
cyclists were similar. The literature also supports
the needs of moisture/heat transfer properties and
lightweight of cycling clothes [37]. In addition, it was
determined in a survey based study that the most
common discomfort problems of cyclists were related
to moisture and thermal discomfort sensation in their
current clothes [2].
3.4 Seam problems of cycling clothes
Most of the respondents (75%) stated that they did
not have seam problems (Figure 7a). The rest
of the respondents experienced marks on their
bodies along the seam lines, the most (Likert
mean: 2.5). The seam related problems were
detected in the armpit area on top wear and in crotch
area on bottom wear (Figures 7c, 7d).
3.5 Cycling clothes preferences and
maintenance behaviors
Cycling clothes preferences of respondents are given
in Figure 8. According to Figure 8a,
59% of respondents wore M or L size clothes.
69% of respondents preferred fitted models instead
of regular models (Figure 8b). 87% of respondents
preferred cycling clothes with 3 or more pockets
(Figure 8c). 73% of respondents preferred raglan
armhole and 74% of respondents preferred full length
zipper on the top wear (Figures 8d, 8f). Raglan
armhole increases the movement range of shoulder
and zipper provides easy take off of the clothes [37].
Collar preferences changed according to model
(Figure 8e). Collar preferences may be up to
the fashion. As the bottom clothes, almost half
of the respondents preferred tights with straps while
the rest half preferred tights without straps
(Figure 8g). In Figure 8h, sleeve length preferences
of respondents in both summer and winter time are
presented. According to the figure, most
of the respondents preferred short sleeve in summer
time and long sleeve in winter time, rather than
the other sleeve types such as sleeveless, elbow and
¾ sleeve lengths.

Images of some commercial cycling top wears
are given in Figure 9. By considering both
the commercial products and survey results, a basic
cycling top wear was designed as given in Figure 10.
It is planned to be made of elastane containing
knitted fabric. It is designed to be fit cut; it has
3 pockets, raglan armhole and full length zipper,
according to clothing preferences of survey

Only in Turkey in the year of 2018, 8514 traffic
accidents included bicycles and 125 cyclists died
according to official statistics [38]. Therefore, in this
study, information about both injuries in accidents
and visibility preferences were collected to develop
a clothing design that would provide extra protection
to the wearer.
According to survey results, shoulders, elbows and
arm area were the most injured areas that could be
protected by the top wear. In order to provide
protection to these areas, the outer side of the sleeve
was designed to be supported with a spacer fabric
and aramid fabric combination. As aramid fabric has
high strength [39], it will be durable against cutting
when the arm of the cyclist contact with the road
in case of fall. So the exposure of the skin to the road
will be inhibited and it is expected to prevent wounds.
Short sleeve was not preferred because
of the aramid support along the arm.
Also, the elbow and shoulder parts of the clothing
was planned to be supported with additional knitted
spacer pads in order to absorb the impact in case
of fall.
For the ideal protection, weft knitted spacer fabrics
with different thicknesses can be tested to determine
their damping capability of impact [40]. Spacer
fabrics can provide protection while maintaining
Also, impact absorbing pads may be produced from
silicon containing cushions, which have currently use
in cycling shorts as given in Figure 11.
Figure 11 Silicone foam containing cycling short pad
vs spacer fabric for soft padding: a) silicon sponge [45],
b) spacer fabrics [46]
For the sleeve construction, different designs were
developed and 5 of them are given in Figure 12.
In these designs, the coverage and patterns
of aramid and spacer pads are altered. The designs
of a, b and d were eliminated because
of the voluminous structure of spacer pads.
Those designs could result with reduced mobility and
sewing problems in the curvy armhole places.
Figure 12e was preferred as the final sleeve design
as the spacer pads were placed in the target sides
as shoulder and elbow. In addition, it was more
advantageous by having less amount of expensive
aramid fabric, when compared to design
in Figure 12c.
To have an idea about the compatibility of knitted
polyester fabric and aramid fabric, a sewing trial was
performed. For this purpose, a knitted aramid fabric
was sewn with a single-jersey polyester fabric by
using 5 yarn overlock stitch as shown in Figure 13.
Fibres and Textiles 28(1), 2021 38
Two fabrics (aramid and polyester knitted fabrics)
were found to be compatible in terms of sewability
and stretching, also there were no visual problems
along the seamline. Here, polyester was trialed
because it is used in commercial cycling clothes,
extensively. And the reason to support the polyester
fabric with aramid was that the aramid fabrics had
high mechanical properties. In the further studies,
fabrics with different raw materials can be tested
as alternatives. By considering these results and
sketches, the final cycling top wear was designed
as in Figure 14.
In the design, to eliminate the seam problems
in the armpit area, a diamond gusset may be added
as shown in top left side of Figure 14. Also, this
gusset may be manufactured from meshed fabric
in order to enhance the heat and moisture transfer
from the armpit. The design can be used for cycling
in dry weathers of spring or autumn seasons.
Also, it can be used as an inner layer for winter
season, too. For the summer season, the sleeve
can be made of an elastane containing meshed
fabric in order to improve the moisture and air
permeability, to maintain both the protection and
comfort at the same time (Figure 15).
The visibility of top wear was enhanced by using
contrast and vivid neon colors and active LED
supports. Most of the respondents stated that they
did not use LEDs on their cycling clothes. Literature
showed that the usage of flashing LEDS can improve
the recognition of cyclist in the dark. Koo and
Huang’s study [13] suggested to put the flashing
LEDs on the lower garment at hip, knee and ankle.
But also, the LED configuration on the top wear took
good scores. Therefore, for this study, LEDs’
configurations were designed as given in Figure 14.
An alternative LED configuration can be formed
as in Figure 16. A LED array was planned to be
placed in the front and back torso as given in figures.
Also, a small pocket was added to carry the battery.
Kgatuke et al [14] made a design by inserting LEDs
in the weaving process. According to our survey
results, most of the cyclists wash their clothes
in washing machine, so, in this study, detachable
LED arrays were proposed in the design to plug off
easily before washing. The attachment of LED arrays
may be enabled with Velcro or snap fasteners.
A variant of this cloth might be designed with
integrated gloves.

Additional important implications of this study can be
summarized as below:
- More than half of the cyclists stated that they used
heart rate sensors. 42% of the respondents used
chest type heart rate sensors that should have high
contact with the body. As an alternative, ear type
heart rate sensors may be integrated to the cycling
top wear as the authors realized for sailing
garments in previous studies [47]. It can provide
wear comfort and extra mobility to the cyclists.
- Cyclists have high expectations from their clothes
in terms of physiological comfort. Moisture
management finishing may enhance the comfort
properties of cycling jerseys.
- There were no serious problems about the seams
of cycling clothes. But some cyclists stated that,
their seams left marks on their bodies. It is related
to fit cut of cycling clothes those contact with body
tightly. This problem can be solved by replacing
sewn seams with taped seams. Taped seams
provide a flat and smooth hand to the seam [48].
This can be applied along the straight side seams
or lowly curved seams as it is harder to apply
welding tapes in highly curved areas such as
crotch and armpit seams.
Within the context of this study, an extensive survey
research was performed to collect essential
information to create the design idea of a more
functional and protective cycling cloth.
By considering survey results and literature search,
2D flats of protective cycling top wears were created
as proposals.
For the design development process, patchwork
design approach was found advantageous
in obtaining protective clothing that also exhibited
high level of comfort. In the designs, 4 types of textile
structures, namely elastane containing knitted
polyester fabric, knitted aramid fabric, meshed
polyester fabric and spacer fabrics, were combined
together by considering their general properties. In
the further studies, material alternatives are planned
to be tested for the selection of the best
In addition, detachable LED configurations were
found suitable for visibility enhancement and easy
In the further studies, the cycling cloth designs can
be realized and wear trials can be done for long term
studies. This study is expected to help the cycling
clothes producers by revealing real problems and
requirements of cyclists from their clothes. Also, it is
expected to sketch a new perspective for the design
of protective cycling clothes.

... For athlete adoption of wearable sensors, prevention of discomfort at sensor locations will increase overall user satisfaction. Prior studies indicated the importance of the fabric, fit, and comfort factors when investigating the validity of wearable sensor data [42][43][44]. As noted in the methods, athletes' shorts were fitted based on personal preference and adjusted when the shorts felt too tight after embedding the sEMG pads. ...

There is scarce research into the use of Strive Sense3 smart compression shorts to measure external load with accelerometry and muscle load (i.e., muscle activations) with surface electromyography in basketball. Sixteen external load and muscle load variables were measured from 15 National Collegiate Athletic Association Division I men’s basketball players with 1137 session records. The data were analyzed for player positions of Centers (n = 4), Forwards (n = 4), and Guards (n = 7). Nonparametric bootstrapping was used to find significant differences between training and game sessions. Significant differences were found in all variables except Number of Jumps and all muscle load variables for Guards, and all variables except Muscle Load for Forwards. For Centers, the Average Speed, Average Max Speed, and Total Hamstring, Glute, Left, and Right Muscle variables were significantly different (p < 0.05). Principal component analysis was conducted on the external load variables. Most of the variance was explained within two principal components (70.4% in the worst case). Variable loadings of principal components for each position were similar during training but differed during games, especially for the Forward position. Measuring muscle activation provides additional information in which the demands of each playing position can be differentiated during training and competition.

Most E-textile research tends to fall within the arts or science disciplinary boundaries, despite E-textiles themselves being interdisciplinary in nature. This work explores how contemporary woven textile practice methodologies can play a role within interdisciplinary research, expanding the creative and technical applications of materials and technologies. A team of electronics, textiles, and fashion specialists was formed to design and make an illuminated jacket for use by cyclists. The jacket incorporated bespoke woven panels that integrated electronic yarns within the pattern. The development of this prototype raised questions about the use of craft practice methodologies in the development of new E-textiles.

This study investigated the relationship between pain/injury and training characteristics in cyclists. In addition, ergonomic wear comfort of their garments was investigated. A total of 94 complete questionnaire responses were analyzed. The result indicated that lower back pain was the most prevalent injury causing the highest rates of functional damage and medical attention. The injury level of cyclists was affected by the cluster with elite cyclists reporting pain while cycling. Many cyclists were not very satisfied with the comfort level of their current outfit, 39% of respondents were experienced with different discomfort sensations. The most frequent causes of discomfort were thermal and moisture discomfort sensation related to fabric characteristics. Moreover, the design and fit of the garment were considered as a cause of discomfort next to thermal discomfort sensation. Therefore, it could be concluded that garments that have good ventilation or breathability and very good fit values were preferred by cyclists. Design, limited choice (availability), appearance/look and quality were the main reason for their brand selection preferences.

Hintzy, F, Gregoire, N, Samozino, P, Chiementin, X, Bertucci, W, and Rossi, J. Effect of thigh-compression shorts on muscle activity and soft-tissue vibration during cycling. J Strength Cond Res 33(8): 2145-2152, 2019-This study examined the effects of different levels of thigh compression (0, 2, 6, and 15 mm Hg) in shorts on both vibration and muscle activity of the thigh during cycling with superimposed vibrations. Twelve healthy males performed a 18-minute rectangular cycling test per shorts condition (randomized cross-over design) on a specifically designed vibrating cycloergometer. Each test was composed of 2 intensity levels (moderate then high) and 3 vibration frequencies of 18.3, 22.4, and 26.3 Hz, corresponding to cadences of 70, 85, and 100 rpm, respectively. Muscle vibrations were measured with 2 triaxial accelerometers located before and on the lower-body compression garment, to quantify, respectively, the input and output vibrations, and vastus lateralis muscle activity was measured using surface electromyography. Both vibration and electromyography signals were measured throughout the tests and quantified using root-mean-square analyses. The study showed that the use of a thigh-compression shorts at 6-15 mm Hg significantly reduced both the vibration transmissibility to the thigh and the muscle activity, with higher effect size at higher superimposed vibrations. The thigh-compression shorts garment therefore seems to be 1 way to dampen vibrations transmitted to the cyclists and then to reduce the negative consequences of these vibrations on muscles.
Conference Paper
To examine creative smart clothing design for sports and fitness a fastest growing wearable market, the current study examined an interactive cycling outfit incorporating solar powered LED sensor lights. The completed garment design contributes to eco-design approaches for sustainability, history of fashion (1890's the Rational Cycling Outfit) and aesthetic appeal of clothing. Semi-transparent Hanji fabrics (made with paper mulberry by Korean traditional paper making techniques) and high-tech trim materials (e.g., 3M reflective strips, stretch air-mesh fabric, fluorescent tape) were used to complete the garment part of the current design. This study will fill the gap in the literature for exploring creative design ideas and techniques to design smart clothing for cycling. The area of current smart clothing research would be beneficial for educators to create impactful new interdisciplinary design programs and course contents by incorporating wearable technology, containing new emerging concepts that can aid students to expand their personal and professional spheres in global industry. For designers and marketers in the wearable technology industry, this study will also suggest future research direction on smart clothing design to address aesthetic aspects desired by consumers. Finally, this design shed new light on the fashion history of the late Victorian fashion through the re-interpretation of the Rational Cycling Outfit.
Given the premise that cycling encourages a healthy lifestyle and promotes wellbeing, this paper describes the design process for the development of a cycling garment, with embedded electrodes for heart rate measurement to further widen the possibilities of health and performance monitoring, in a practical and unobtrusive way. Electrodes were produced and tested, using different textile materials and techniques. Signal measurement is based on the BBB Y8YBH20 heart rate monitor and performance tests were done using the Polar Beat mobile app. Finally, a prototype of the garment is presented.
This study is the first randomised controlled trial (RCT) of the safety effect of high-visibility bicycle clothing. The hypothesis was that the number of cyclist accidents can be reduced by increasing the visibility of the cyclists. The study design was an RCT with 6793 volunteer cyclists - 3402 test cyclists (with a yellow jacket) and 3391 control cyclists (without the jacket). The safety effect of the jacket was analysed by comparing the number of self-reported accidents for the two groups. The accident rate (AR) (accidents per person month) for personal injury accidents (PIAs) for the test group was 47% lower than that of the control group. For accidents involving cyclists and motor vehicles, it was 55% lower. The study was non-blinded, and the number of reported single accidents was significantly lower in the test group than in the control group. This is likely a result of a response bias, since the bicycle jacket was not expected to affect the number of single accidents. To compensate for this bias, a separate analysis was carried out. This analysis reduced the effect of the jacket from 47% to 38%.
