Gallery: Hand-Operated WISB Bike Converts from Wheelchair to Sport Bike...


The WISB hand bike, designed by Bar Claudia, is a combination of a recumbent bike, a wheelchair, and a sport bike. Just by switching between “high” and “low” modes, riders can extend the bike frame for outdoor recumbent biking or compress it for indoor use. The WISB bike is hand-operated in all modes, so users with limited or no leg function can seamlessly transition from daily wheelchair function to sports activities.

The video above shows the WISB bike in action, with not only the footprint of the bike but also the back of the chair shifting between use modes. What do you think of this design? To us the seat and pedals seem a little small for people with the most limited mobility, but the design holds promise.

    Interesting design, but it’s missing some key aspects; where do the feet go? Anti-tip bars in the back, for when it changes back and forth? Wheel to seat placement for the downward push seems to wide when in manual mode and also to far forward. As a user these are the first things I noticed. Wheel guard look impressive and the overall design looks pleasing to the eye. Side to side stability looks sound. Best of luck, it was nice to look at.

    What about taller or shorter people? This should be adjustable to fit different sizes. Like the idea though.

    If only Roosevelt has one of those.
