Concept  —  Important  —  Versions

Due to my paralysis, I use a wheelchair and enjoy handcycling. I would like to help other handicapped people to get the same feeling (Within their possibilities). Therefore, I put my DIY handcycle idea (and other crazy ideas) as “open source without commercial use of the general public” (more at the end of the text). I am thinking particularly of those more challanged wheelchair users, who can not afford a handcycle. As I use a commercial handcycle myself, my aim is not to compete with the handcycle manufacturers or their cycles.

Never forget, the most important is the rider, the human! The vehicle has to be built for the needs of the rider, well his requirements. For example, the type of his impairment (such as the hight of his paralysis,  his strength, etc.), where would he like to ride? For what purpose will he use his bike? His economics ;), etc.

I would be very happy about images and stories that result from my idea. Of course I would like to publish ‘em here.

Many Greetings Klaus

Dein Handbike selber bauen

Das original Konzept vom santa66-Handbike oder die Idee sind im wesentlichen 2 Punkte:

Teile eines Alten Fahrrads benutzen und den Rollstuhl umlegen, um auf der Lehne (wegen der Sitzhöhe) zu sitzen (siehe Skizze).

Etwas komkreter bedeutet das:

Das Handbiken als “Do it yourself” bzw. Open Source vor allem
für Rollstuhlfahrer ohne finanzielle Mittel, möglich zu machen.
Dazu braucht man einen Rollstuhl und ein altes Fahrrad. Am Fahrrad wird gesägt,geschweißt, geschraubt und so der Rahmen erzeugt. (Kann man selber machen, aber auch machen lassen. (Vielleicht vom Kumpel oder dem Schlosser an der Ecke)
Was dabei entsteht wird an den nach hinten umgelegten Rollstuhl angeschraubt.
Am Ende sollte dabei ein Handbike nahezu ohne Kosten (Vom alten Fahrrad und von den Arbeitskosten abgesehen) entstehen.




Important suggestions

The wheelchair must not have any camber on the wheels, or install additional jacks (without camber). Camber means at this idea a slow down”!

– Ensure that there is distance between pedals and thighs. The hands must not touch the thighs!

– The distance between the pedals and the upper body should not be too large. The upper body should not move while riding (forward nor backward).

Try to use steel (and not alloy). It is easier to find someone to weld it!

Do not forget the ground clearance!

Check the alignment (lining up) of front wheel and steering head (best on a frame”).

Make the frame strong enough!

as seen at Noe‘s bike, improves “dampingof the pivot the driving characteristics (prevents fluttering).

, there are several possibilities: Springs as mounted at Noe’s Bike or similarly mounted gas shock absorbers.

Another cheap way should be with a screw slightly fastened to slow down the rotation. But I have not tried this.
