This is why i service my ebike yearly.... If you spend the money on a bike spend the time to look after it also dont abuse it......

I believe regular scheduled maintenance is the key like everything else. Did you get it used? That thing went through hell!

is the hall sensor quick connect bigger than the 500watt version? i have a 500 watt version and was wondering if you need a special ext to connect it to the exsisting harness from controller

It looks like somebody did that stupid idea where they inject their 750W motor with something like mineral oil to "help' with cooling. The problem is these things aren't air tight so all that crap almost immediately all leaks out and creates a nice sticky surface for any sort of dirt and grime to stick to

This might prevent from this/make it easier: - Open new motor, grease it, put rust protection color on it - Check that thru cable no water is coming inside motor - Buy a second motor, so you can replace later what's needed

Good stuff but how would You go about without slide hammer puller? Could I just whack them bearings from behind since there´s space between? I have a similar motor and plan to service it. How tight do You pull them screws in the flange that holds the cassette sprocket, I always like to use a torque wrench. Can You put a number on that? Yeah, it ain´t rocket science but I very much like my torque numbers as I HATE extracting broken bolts. So I better not tear them in the first place. Thank You Buddy, keep the good stuff coming, I just have a tiny shop in an attic but try to estabilsh myself as backyard mechanic by watching stuff like this and trying it out on my own devices first before I advertise like a brake service. It really is fun to me and the happy smiles I get when a job is well done makes it all worthwhile.

its no wonder water gets in there is no gasket or any seal between the motor casing parts, maybe a smear of Plumber Mait might help?

Help!!! My electric bicycle started displaying error 24, all the wiring is well connected and in perfect condition. When im activate the accelerator the engine only turns a couple of times, and makes a small noise. My engine no longer works? It only has 1500 miles.

Have a similar problem with my inner bearings, anyone know what size these are?

Anyone know if they make stainless steel teeth wheels for the motor as an upgrade?

How did you get the clutch assembly off?

Hi what's the spoke size in that rim?

How many miles did you ride for the motor turn into rust ?

Hi - what size rim and tire is this?

Hi . It's a tire Michelin of moto ?

Looks to me like that thing was underwater for quite some time!
