Hi, all
I have a home made friction drive. Before I added a bungee cord to help hold the rack down (and the spindle against the tire), my top speed was about 25 mph and going up hills was weak and slow.
After I added a bungee cord, my top speed is 30 mph and it goes up hill much better.
The bungee cord also puts stress on the frame and engine in my home made contraption but, so far, with over 150 miles, mine is still holding together and running.
I thought I should mention this in case anyone is wondering.

If you had bearings and support on both sides of that spindle you'd probably do better.

Hi, Zev0
Thanks for the input. I agree. I did not have the U member or bearings and bearing blocks on hand to build that but I'd love to go after that concept.
I'd especially like to put a bearing on the end that is farthest from the engine, at least, to reduce the side load on the crank.

Have fun!

Hi, MountainMan,
Thanks for the nice comments!
If you want/need more details of my project, please feel free to go to my personal blog where I've got details, pictures and even a video:

The project was a blast and I'm now working on a recumbent.
I'll post more when it's done.

:)

Thanks again!

Great project...but I just imagine riding that thing with the handle like that...and being arrested for appearing in public in a "discernibly turgid state"...as the law says.
