Arm powered bikes

I was reading this article on arm powered bikes and got an idea

Varibike lets you pedal with your legs ? and your arms

Wouldn't it be better to push the handlebars forward and back rather that crank?

I would think it would be easier to steer that way

I'm thinking or building one

It would be nice to add an upper body workout

What are your thoughts on this?

That varibike thing is total jackass. Absolute junk.

The handlebars are chopped to make room for the hand crank.

When you do actuate the hand cranks there is no way to steer. You are essentially riding with no hands. The fork is pointed backwards, huge amount of trail to keep the thing stable with no hands.

I kind of like the Schwinn Airdyne. It doesn't actually move anywhere, but the concept is interesting.



There would be a few different ways one might accomplish steering.

It's funny, you can see how terrible it is to turn and the handling in general looks awful - even for the presumably practiced people in the video. Why do people keep inventing crap like this?

Try pushing and pulling on the bars on your current bike. You can push with your weight, but there's nothing to support yourself when you try to pull.

I just deleted my post pointing to this thread - scrolled right past your post.

hand cycles are trikes that are powered by your arms, usually because you legs were damaged/ amputated

or birth-defects had them not develop.. I have known a world-class wheel chair racing athlete in the latter situation, since birth.

and others that take along their prosthetic limbs for when not on their Hand Cycle.

there the cranks are same side, not alternating, power stroke is pulling back , involving the Back muscles too ..


another thing is Row bikes .. just like pulling the Oars on your Dory, Dingy (or racing Shell. with sliding seat)
