Ron,
Thanks for the request. After I retired (and Zipcycle had closed), I still built a few bikes for friends, an and one requested that I help him add power to his "John Deere" bicycle. It was so much fun that I had to build one for myself. This should be in photo #1. I have since added a miniature square bale of hay on the luggage rack. The second one is for parades (where I don't have to balance it) is a sidecar version that I am still working on adding a body to the sidecar frame. This should be in photo #2. The 3rd photo should be a close-up of the original drive system with the covers removed.
Still having fun in my 70s.

xlite,
Thanks for the question. The original website is no longer maintained, but the entire website is archived at one of the dealers' website. Try [url=http://www.redelephants.com/Zipcycle.html]. This site contains a complete series of photos and a complete copy of the owner's manual.

Thanks for the pictures and info ! ! !

Thanks Tom. Very nice setups!

Hello All,
My buddy Mike Got my new friction roller finished. He also made a cup for the bearing on the other end of the roller. We fabbed a mount for the bearing and got it setup on the bike. looks like I am back in business again. The first two pics are of the roller and bearing and cup. The third pic is of the completed bearing arm minus the spring holder on top.

Got the engine on the bike and the roller tried yo unscrew while bump starting. We put two setscrews in the roller and loctited it to the crank. I will find out tomorrow if this works. Now I have to rig a means to lift the engine off the wheel, a kill switch, and a throttle.

Very cool! I have been itching to try recument but not sure howthe local cops react. First I need to build a bike because the commercial ones are way expensive.
