Planetary Gears

Brought the back tire into the shop after talking to the mechanic about the broken rear hub motor. Waited in town while the mechanic took it apart and replaced the planetary gears. Works perfect and finally quiet now. Excellent work and communication.

worked on my sondors x w/500 watt motor. good price and shipping was excellent,2-days it was installed and riding. Thanks Kyle!

I installed the gears on my Rad Rover 5. I watched a you tube video. They fit perfectly and the work was simple and easy. No more crunching noises.

fast shipment, good packaging

I wish I could find these planetary gears in metal. Or I wish I could buy nylon gears in bulk. I weigh 220. With racks and stuff, I'm always maxed out 275 total and I burned through my first set stock planetary gears on my Bafang 750 I bought at Bolton in 200 miles. I'm going to have to shed 50 myself, get used to traveling light, or get used to replacing nylon planetary gears. Is there a metal option?

Airplane grease saves gears, for the guy saying he burns through his gears I’m also a big heavy guy with a big heavy custom RadRover my advice get airplane grease it’s a red grease pack your gears with a full tube of it, that’s what I’ve done and my gears are still holding up, don’t go lightly on the grease, Pack the whole open area with it.

I chipped a few teeth on my Runner stock motor, it sounded like it was crushing rocks. I contacted Bolton bikes and found they had these gears for sale. they fit perfectly in my stock motor. Thanks Bolton
