Rhoades Car - The 4-wheel bike that drives like a car.
Nearly 30 years ago, J. David Rhoades had a unique idea – to design and market a 4-wheel bicycle that everyone could enjoy. He appropriately named it the Rhoades Car... http://www.rhoadescar.com/rcar/index.shtml
Clever. Drive on the front wheel to pull you through would be great, though adding weight and complexity.
ReplyDeleteI did not see how the front-drive was connected on the video or site (http://www.kateleeming.com/).
I found a link to the drive system through the brochure on her site:

Ahh... Power for the front comes from the left-side of the rear wheel, through a drive-shaft through the frame, to "counter rotating bevel gears located within the head tube", to rotating stanchions down the fork. Clever, and the builder certainly knows much I do not, but I am left with nagging questions:
ReplyDelete- complex much?
- field maintenance?
- why is the front driven off the rear wheel and not the left-side of the crank? It's closer, so there should be less power loss, no?
Thanks for the links! I couldn't tell if those were studded tires or not.
