Clip-On Docking System

Viper XS  can be connected to most rigid wheelchairs via a unique Clip-On docking system that requires no extra brackets fitted to the wheelchair. All mounting and locking hardware is built into the cycle, with no loose or separate elements.

Although Viper XS has been designed to be connected to rigid framed wheelchairs, because of it’s off road capabilities (torque, speed, and weight) we recommend that a fully braced box type rigid chair is used. Examples of this type of wheelchair, are the Quickie GPV, RGK Chrome, TiLite AeroT. When the Viper XS is used with an unbraced L shaped rigid chair, the chair will tend to flex especially when braking.

Super Strong and Easy to Dock

The rider wheels up to the Clip On handcycle and into the clamps. With a few turns of the levers the clamps grip to the front down tubes of the wheelchair. The rider then pushes the top of the handcycle away from himself or herself, this motion lifts the wheelchair casters off the ground; the latching system will simultaneously lock in to place. Once docked, a secondary safety lock is activated. This safety lock ensures that the system cannot be undocked accidently, To undock the rider must be stationary.

The PVC coated clamping jaws have been designed to lock onto 19mm tube all the way up to 35mm tube, this covers a vast range of wheelchairs. The amount of adjustability available ensures our system will fit tapered, V, and straight wheelchair front down tubes.

Please go to the video gallery to view the docking on procedure.
