The Ultra Motors A2B Electric Bike solves all kinds of problems. You pollute less, save money on gas and you don't have to pedal it.
You can go 20 miles at 20 mph without pedaling at all, making it more of a scooter than a bike. If you feel like getting a little workout, pedal along and the motor will assist you.
It uses Japanese lithium ion battery cells so when it needs more power, just plug it in. It's the ultimate in hybrid technology.
At $2,699, you probably don't want to leave this gadget on the street, even though it weighs 75 lbs, you'll have trouble carrying it up the stairs.
