What weighs 15lbs, gets 200 miles per gallon, and drives at 20 mph?The Revo Wheel.
This wheel is an engineering marvel that is meant to replace the front wheel in your bike, basically turning your bike into a slow moped.
Pedaling is for suckers I guess.
The thing is, while certainly lightish, at 15lbs that's going to make actually pedaling your bike a whole lot more difficult which of course for most, will make pedaling a rarity.
$599US is the price you'll have to pay to turn your trusty bike, a source of health and fitness, into a sweat free, zero-Calorie moped.
Please don't buy one.
