Re:Or maybe... (Score 1)

Using a $40 used mountain bike and a $300 electric motor + speed controller, a $10 sprocket and $100 of lead acid batteries, some wire, a soldering iron, some scrap metal, screws, a drill and a 30 amp circuit breaker you can make a bike that goes ~30 mph if you pedal and open the throttle all the way... ~$500 for a e-bike that goes 3 times as fast as a segway. Why would anyone want a segway again?
