Roll ‘n Ride

Roll 'n Ride is a bicycle transportation system integrated with bus public transit. A lack of a method to transport bicycles to complete the post-bus leg of the trip reduces the willingness to use either as the primary transportation option. This concept encourages the use of more active mobility and public transportation as an alternative to car dependency in everyday journeys.

Congestion on roads is getting worse and will not go away anytime soon. Public transit and active mobility options are an alternative for people to complete their journeys. However, integrating and utilising both methods can be difficult due to the inability to bring personal active mobility transportation onto public transit. Space is limited and prioritised for passenger transportation, and bringing larger objects is prohibited, as is the case with bicycles on buses.



The three mainstream travel options are driving a car, catching public transit or using an active mobility option (walking, scootering or biking). Automobiles are facing more congestion as well as adverse environmental externalities. Public transit is limited to destinations close to stations and routes, and active mobility options cannot travel great distances. Therefore, a method that can better integrate public transit and active mobility, especially biking, will have the potential to greatly increase the use of both transportation methods as a viable car alternative option.


Academic literature was first reviewed to ascertain what options and methods are currently available and any gaps in which an opportunity may be presented. Reviewing sources revealed the results of previous studies and lessons learnt. Additionally, both the current state of active mobility and public transit and potential future developments were noted and used to inform the development of concepts.


Interviews were conducted with persons with knowledge of the subject matter. This included a professor whose study areas are public transport and active mobility, as well as two local city council personnel in the bus network planning and active mobility functions. The interviews provided great insight into the topics and primary research that greatly influenced concept development.


Surveys were sent out to gauge and gain an understanding of the general population’s view of active mobility and public transport. Unlike interviews, the collected survey data is less reliable but provides a great range of information and sentiment. The analysed results were used in directing the design development as it provided a guide as to what users may expect of the design outcome.


Five initial concepts were developed, breaking down into two diverging design directions. The first was focused on enhancing/developing storage solutions at transit stops and stations, emphasising the small local suburban stops. The second direction concentrated on developing a method to bring active mobility transport (with an emphasis on bicycles) on public transport to complete the journey after the public transit leg.

The latter direction was chosen for further development as it had the potential to have a more significant effect on increasing the usage of public transport and active mobility as the primary transportation option. The ability to use a bike before and after riding public transit increases the catchment radius of stops and the range in which a person is willing to travel to their destination.

ROll ‘n ride

Roll ‘n Ride is a storage solution that provides the ability for passengers to bring their bicycles with them and use to reach their final destination. Bikes are placed on the racks and clamp down. They are then lifted up and slotted horizontally into the carriages. Both carriages are then hoisted up on top of the bus and stowed away while the bus is in transit. The passenger can then access their bike at their designated stop.

Roll ‘n Ride operates using winched cable hoists as well as horizontal and vertical guide rails for the movement of the carriages. The bikes are secured to the racking with spring-loaded clamps that clamp onto the wheel and support the frame of the bike when it is in the horizontal position. The rack with the bike is returned to its slot in the carriage and, while doing so, turned nighty-degrees into a horizontal positioning.

Key benefits

Public transport is about providing a social service and utility. While it may take more time and can be inconvenient, it provides a certain service, especially for those who need it or don’t have alternatives.



Another rationale for storing bikes on the roof aside from passenger capacity is the length limitation of buses. Buses are built to the maximum length allowed on roads to maximise passenger capacity. However, front or rear bike racks would increase this length. This would be an issue when the bus is turning as it increases its turning radius. Narrow roads, inner-city streets and underground roads (e.g. Brisbane Busway) would be problematic to navigate. Additional safety concerns exist when passengers have to stand on the road to store their bikes. Front and rear-mounted racks are also subject to opportunistic theft as they are accessible at any time the bus is not in motion.

In regards to height, the general minimum on-road height clearance is 4.5m, with most bridges’ clearance also being that. With Roll ‘n Ride added on top of existing buses, it would not exceed 4.2m.

COmponents of the system

Complete system
Housing unit and lifting arm
Loaded carriages
Unloaded carriages
Bike racks


The housing unit and carriages are steel frames with fibreglass panelling. The steel frame provides a rigid structure, while the fibreglass panelling is lightweight and provides the aesthetics.
The lifting arm is made of carbon fibre and steel to balance strength, longevity, weight and cost.
The bike racks are cast moulded anodised aluminium. Aluminum was chosen for its durability relative to its light weight.
The wheel clamps are moulded aluminium with rubber padding for the tyre clamp and function using extension springs.

The colour scheme is easily interchangeable and would be chosen to fit the with aesthetics of the bus fleet of any local city/region.

Design Process

Phase one of the project involved researching the topic areas and analysing existing solutions or the lack of them. From that, some initial design concepts were drawn to explore and later determine possible design directions that could be a potential solution. Phase two consisted of further developing the chosen concept from the initial ideas. Possibilities and limitations were explored to improve and refine the design. Finally, phase three involved testing the idea, which was primarily done in CAD due to the scale of the design. Limited physical testing was also conducted but more to the effect of exploring spatial considerations. After testing, further refinement and alterations, the design was delivered.
