Experience endless power on every journey when you have the SuperWheel Power Assistance System on your bike. This revolutionary bike wheel actually has a power assistance system built in. Through WTECT (weight to energy conversion technology), this transforms your weight into power as you ride. With each rotation, your weight on the pedals feeds the system to improve cycling efficiency by 30%. SuperWheel makes it easy to tackle journeys of any length. And, because it uses this unique technology, it’s also free of batteries. That means you never have to waste time recharging; it always works. It also means you get the e-bike experience without the limits of range. Cyclists of all abilities will love the extra boost as the SuperWheel easily attaches to any bike.
