People love their bikes, but many commuters would love the convenience of powered transport. The Swytch turns any bike into an electric-assisted conveyance. It consists of a power pack with an LCD readout that attaches to the bike's handlebars, a 250W hub motor wheel, and a pedal sensor. The motor kicks in automatically as the bike is pedaled, with manual throttle control available as an add-on. It's 100% waterproof, has a top speed of 15 mph, and has a maximum range of 50 miles per charge.
