The first and only geared belt drive bicycle assist engine on the market.
The Drive Ring is made of nylon, reinforced gear material, for long life and durability. Fits 24", 26" or 700c wheels with 32 or 36 spokes. Rotate the ring over your wheel until the spoke slots align with wheel's spokes, using our 4n1 Ring/Spoke/Gear Key; the spokes easily click into the slots. Securely fits most spoke sizes from 15 gauge to 12 gauge. **Click here for 'How to' use our 4n1 Key**
With our patented design, the drive ring is self centering, there is no adjustment - one piece to install and it doesn't come off easily. The Drive Ring requires 1 1/4 inch between the rear fork and the spokes for proper clearance. **Click here for How to measure**
The geared Drive Belt is Kevlar reinforced for long life and durability. Although most of our customers find the belt will last for more than a year, riding style dictates belt life. Breaking strength of 1280 lbs. Extend the life of your belt, reduce stress and pedal a stroke or two as you take off or accelerate.

you wouldn't take a Porche 911 turbo to go rock cralling in Moab, and you wouldn't take a lifted rock crawler Jeep to race in La Mons.
