SPIKE adaptive bike
-
The SPIKE adaptive bike is mainly used by children and teenagers but also by adults who like a simple and compact bike. It is easier to cover longer distances with ergonomic movement processes using one's own wheelchair. This expands the activity radius.
Through the product's larger drive wheel (compared to the caster wheels of the wheelchair) and the wheelchair's steering wheels which are raised from the ground uneven routes and barriers can overcome more easily and without danger. The downhill speed can be regulated via the product's braking systems, so that downhill slopes can be travelled on safely.
Its weight of 7.3 kg makes it a particularly light adaptive bike. Due to the wide selection of high-quality hub gears, optimum adaptation is possible for any user.
Since the SPIKE is very compact and simple, it has a very small turning circle and does not require a lot of space, which makes it ideal for narrow alleys or public transport, for example. The SPIKE is therefore also perfect for your journey to work or school and for city tours.

Compact, agile & simple
Due to its simple fittings and compact dimensions, the SPIKE is ideal for children and adolescents as well as adults who want a light adaptive bike for getting around the city or going to work.
Simple transport
The SPIKE is a lightweight, starting from 7.3 kg with a pack size of 98 x 43 x 50.8 cm and up. This means it is ideal for loading in a car.


Grow-along function and optimum adjustment to the user’s requirements and abilities
Adjustment of the angle and length of the bottom bracket support and adjustment of the angle, height and length of the removable frame adapter allow for continuous easy adaptation to the user's requirements and capabilities.
Simple handling when connecting and disconnecting with parking stand
The parking stand makes connecting and disconnecting easier, as it holds the bike at the height required for adaptation. The parking stand also allows the bike to be parked safely when disconnected. The parking stand can be folded up against the product with one step when travelling.


Different gear shift systems
The wide range of high-quality hub gear systems from Shimano ensures that every user can find their ideal equipment. In addition, a bottom bracket gearshift can be added to introduce even more gears. A great advantage of hub gear systems is that they can be switched when stationary, which can be very helpful, for example when starting on hills.
Effective brakes
An easy-to-use back-pedal brake is integrated into the hub gear. In addition, a high-quality rim brake can be used to brake.


Sturdy adaptation
Connects via a central adapter (fastened onto the axle or cross-tube under the seat surface or onto the folding mechanism) or front adapter (fastened onto the front frame tubes). The adapters are easily adapted to or removed from the wheelchair. When they are removed, the added weight on the wheelchair is minimal, and there are no restrictions to the functionality of the wheelchair (e.g. folding mechanism). The adapter can be used for all PRO ACTIV adaptive bikes, traction devices and steering attachments with the same wheel size: ONE adapter for MANY combinations.
Wide range of optional extras and accessories
Each SPIKE adaptive bike is a customised model, with dimensions and equipment that are always tailored to the wheelchair user’s needs.
The optional equipment includes features for users with functional impairments, such as various handles/supports, adaptation aids and belts for securing the upper body.
