Aluminum SWB recumbent bike

April 12, 2019

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.

Micro push bike

April 12, 2019

This prototype was my version of a modern micro Hobby Horse. It was intended for short trips to the bus stop, train station or subway.

These bike frames were purposely overbuilt to carry hundreds of pounds. Notice the long steering stick attached to the handle bar. Clever! I also found this cargo carrying bike…

Motorized Delta trike

April 11, 2019

I noticed a front wheel drive trike on the market with a wheel similar to a Unicycle, but unlike a Unicycle you could keep your feet on the pedals when coasting. Although pedaling a large vehicle this way was almost worthless, like a moped it technically could be classified as a motorized trike allowing anyone…

DIY long tail bike

April 11, 2019

I was wanting to see if I could make a medium duty long tail bike. All I had at the time was this lugged frame Diamond back bike. Because of the lugged fittings, I wasn’t comfortable just replacing the upper and lower rear forks. I instead opted to add 7″ of material in-between the existing…
