TDRMOTO 36-Tooth Rear Sprocket Cog For 49cc 66cc 80cc Motorized Push Bike Engines

If you're building or fixing a motorized bicycle (those 49cc, 66cc, or 80cc kits), you're gonna need a good rear sprocket.

This one from TDRMOTO is a 36-tooth cog, which is a common size for a good balance of acceleration and top speed.

It's brand new and ready to bolt onto your rear wheel.

The part number is TJ026#.

It's a solid replacement part for those China girl engine kits.

Made for standard push bike wheels.

Whether you're a builder or a rider, having a spare sprocket is always a good idea.
