Drawing power from an internal 15 amp lithium-ion battery, the PiCycle Electric Bike ($5,000) is a fun and eco-friendly way to get around town. Thanks to its zero-emission 1250 watt / 48 volt motor, it can easily go 30 miles per hour with a range of 20 miles without the use of pedals. Its lightweight curved frame is equipped with a built-in charger, internal hub transmission with shift-on-the-fly capabilities, belt drive system, hydraulic brakes and suspension seat post.
