Frame-mounted bike transmission
Over the past few years I've been developing this bike transmission concept for my own use, but also with an eye toward producing it commercially for markets such as off-road, rental and bike-share where weather-proof operation, ruggedness and versatility of the design would be assets.
Hand-crank modification to recumbent
Last Spring, a week before I was to leave on a 300-mile bike camping trip, I twisted my knee. Rather than skip the trip, which I had been planning all year, I conspired with Ken Rice to find a way to make an arm-cranked bike for myself in the few days I had to prepare for the trip. Kenny made the astute observation that a mountain bike seat tube would fit over the steering post of my low front-wheel drive recumbent, and quickly cut up and welded the appropriate parts for the fixture - in about 15 minutes. In another hour I had it assembled and was riding it. Over the next few days I made hand pedals and mounted a luggage rack to finish things off in time for the ride. I also adapted cat litter buckets for panniers because we had rain on the ride and it was nice to have my stuff completely water safe.
Low-cost, low-slung velomobile
Beginning with a ZOX front wheel drive recumbent design I am developing a low-cost velomobile for urban and suburban riding. I will be using an existing chassis that I've owned for a while, and building a coroplast fairing for it, as shown in the pictures. A future version will have provision to be converted to a trike.
