Segway inventor Dean Kamen is developing a hybrid electric scooter that can run on almost anything that burns.
According to the patent, the bike has a small two-piston Stirling engine right under the seat. Though with an engine of that size, it really isn’t going to provide much juice - not much more than 5bhp.
A Stirling engine is based on tech which predates internal combustion engines by almost 100 years. It’s kinda like a steam engine in the sense that it uses external combustion. They use pistons for the crankshaft, but unlike the alternatives they have no valves for no gas ever enters or leaves the cylinders.

Tony Parker has built an electric motorbike completely from found junk.
Why? The laid-off worker found himself with a lot of time and just began tinkering around the house.

Here’s your eye candy for the day— the Schwinn Tailwind hybrid electric bicycle. The Super Charge ion Battery (SCiB) equipped bike charges via a standard outlet in under 30 minutes (7 minutes via a 40 amp commercial charger). The 5ah, 24V battery works for 2000 charge cycles at full capacity and maintains 80% capacity after 6000 cycles.

My sister and I bought and assembled an electric motor for my dad’s bike this Christmas. It was the first gift he’s ever enjoyed from us.
Recently retired and now living in a suburb of St. Louis, we knew he’d never take to biking as there were a number of screw-this(!) sized hills all throughout his town. Through ten years of teaching I know that adults are far less resilient than children and often times need but one excuse to say “screw this” and go back , in this case, to a steady diet of TV watching. But we were elated to see how much he enjoyed his juiced up Electra Townie! Whether it’s riding with my mom (another proud new owner of an electric bike–she had to keep up), biking to the store for groceries, or putting it on the bike rack and hitting the Katy Trail, few days go by that he’s not on his electric bike.
This began my love affair with electric bikes.

The inventor says riding this bike is easy, you just have to learn to trust it.
18 year old Canadian Ben Gulak has spent a lot of time developing this motorbike, which resembles a unicycle in every way, except that it has two wheels, side by side.
How is it balanced? Ben uses gyroscopic technology to keep the bike upright, and it responds only to body movements. Lean forward, the faster you go, lean backwards and you slow down, and to either side, you get the idea.
It isn’t the speediest bike around, reaching 25 mph on a full charge, which lasts about 2.5 hours. A larger motor, however, would increase the speed, but how fast would you want to go on a unicycle?
