Cassette threaded to the hub drive side >2. spacer The locknut was installed with the bike. It's a chinese (Ancheer) bike, and build was low quality. But I think I understand why the...

    Stripped axle nut

    I checked and the axle threads were not damaged, only the threads on the nut (which is made of softer metal). Pics of the axle below. The silvery stuff is the stripped threads from the removed nut.

    Stripped axle nut

    >You say 'drive side'. Where are the parts that consist of the 'drive'? Do you place a cassette or freehub on there? I took off the freewheel to access the stripped nut. Here are pics for both sides of the axle. The innermost nut in the drive side pic is the one that was pushed further into the...

    Stripped axle nut

    >That's a locking nut in the picture. >There should have been a thick washer somewhere to prevent what happened. Sorry, my terminology is mixed up. Yes, the locking nut is stripped. There were spacers (thick washers) pushing against it, and its thread alone wasn't strong enough to hold it in...

    Stripped axle nut

    I remounted the rear wheel back onto my brother's ebike (after replacing the defective PAS sensor), and encountered another problem. As I tightened the lock nut on the drive side, the spacers pushed on the axle nut in the picture further onto the axle, stripping its threads. It prevents...

    Troubleshooting PAS sensor

    Thanks to docw009 and E-HP for their advice. The replacement PAS sensor is indeed the solution. I still don't understand why it fails in the first place. Regardless, at least that issue is resolved. Onto the next one...

    Troubleshooting PAS sensor

    Hi E-HP, Thanks for bringing the pidgin English to my attention. From what I can tell, both right and left side install says the same thing: "step forward" activates the signal, and "step reverse" doesn't. There's no arrow showing the "forward" direction on the magnet race of the old sensor...

    Troubleshooting PAS sensor

    Hi docw009, I appreciate your input. With the PAS sensor removed, I got a 4.37V from the power pin. Anyway, I pulled the PAS sensor completely off and tested it with a 5V (4xAA) source, and see if I can get any life from the signal pin with the sensor turning. I got no life. So I'll be ordering...

    Troubleshooting PAS sensor

    Hi, I'm an ebike noob trying to fix my brother's ebike, and am looking for some help troubleshooting. The bike is an Ancheer from Amazon, bought a few years ago. AFAICT, it's a fairly generic bike. 500W rear hub motor (no brand). 36V-18A-450Wh Chinese batt pack. The trouble started when the...

    E-bike with lost connection between motor and battery

    To OP: First post to the board, so please excuse any mistake. I'm having a similar problem to OP, and have just registered to this board looking for help. I've ran the same "blown mosfet" test as mentioned in the PDF, and got the same error (discontinuity) as OP. I finally figured out, because...
