Itching to have a test ride. Of all the recumbent bikes I’ve made, this was my favorite and most used. I later added a 3 speed wheel with drum brakes up front, then added pontoons for a kinetic race, which never happened. A minute after this image was taken everything went South. The pontoons flipped…

This was my fourth recumbent build. I built it for my neighbor kid who thoroughly enjoyed it.  

This recumbent weighed in at 25 pounds. The main boom was made using 2″ aluminum tubing. To eliminate stress on the aluminum frame I placed the seat mounds directly over the steering tube and rear wheel stays.

Unfortunately the seat put undue pressure on one’s prostate area. A later version would have included a poly suspension on the rear arm, also having the steering tube and rear…

I injured my knee tendons many years back on a cold ride with my old recumbent. Since then the old injury would occasionally flare up. It had been a while since doing any riding, so I made this simple bike to see if my knees could handle the stress of riding again. I liked the…
