BSHWKP 5pcs Push Bike Gear Flywheel Bevel Pinion Fits 66cc 80cc Motorized Bicycle

just what i needed for my 50cc

There’s not much to say for these little gears except they are pretty strong considering the abuse they see on my bike. i did not have to file the key way, which is usually what has to be done and that is a huge time saver! I wish there was a different set up instead of the straight drive that it is. I’d also like to see the gears in different size options.Would I recommend these gears, absolutely.

They're good replacement parts. Just wish they came with the little keys. But worth the money. If only I could get the old ruined stock gears off the engine I would have 2 more working engines.

I purchased these as my existing crank gear was all chewed up due to the retaining bolt coming loose. Very nice to be able to use one and have 4 extras lying around in case you need them. Very smooth engagement and I have noticed significantly reduced geartrain noise.

I only received 1 out of the 5 gears pictured but amazon refunded me immediately so I cant complain, the gear is the exact same as the one that comes on every engine.

Buen precio. Fácil instalación.

The product came real fast on time just what I needed easy to come off a little hard to get just right to slide back in place need grease a little file or sandpaper and patients to get to install just right the woodruff pin will not go back in place if not positioned in the right place will brake woodruff pin and not go on properly

These are way better then stock. Better metal higher quality.
