February 10, 20197 yr Looks like parmesan to me, I did wonder the same AK, mopeding on WOT on his paper round.
February 10, 20197 yr Author I don't think the hub got hot because I checked it a few times when I used to mess about on it and it was only hand warm. Even if he kept it on a high PAS level it should have handled it as he's only small but yes there is some hills on his paper round which he finds hard, especially on 'double papers' day. There's no throttle fitted and speed limited to 12mph, might reduce that to 10mph next time. Hopefully Xiongda can supply some gears stronger than cheese.
February 10, 20197 yr You need to increase the speed to make it run cooler. Slowing it down is the worst thing for it.
February 10, 20197 yr You need to increase the speed to make it run cooler. Slowing it down is the worst thing for it. I doubt that higher speed would have made much difference. The stress on the inner cogs is inversely proportional to the diameter of the track. This small motor has about 100mm diameter, stress on its inner cogs are 20% more compared to on an ordinary SWXH.
February 10, 20197 yr Yes but he's talking about restricting it to10 mph so both torque and temperature will be higher.
March 6, 20197 yr Author Xiongda told me the gears have been re-designed to make them stronger and so will not fit in my motor inners anymore, so they have sent me a whole new motor inner and it has been delivered already. Excellent customer service from them.

Excellent customer service from them. [ATTACH=full]29365[/ATTACH] Indeed, that is great customer service. I’ve just removed my YTW-06 motor from my bike because it got very noisy. The ‘freewheeling’ clutch type noise got a little worse, but it developed a rattly bearing type noise when pedalling in excess of the motor assist speed. Strangely , it was still relatively quiet when the motor was providing assistance. Gave up and fitted a BBS01B instead (thanks Woosh!). Out of interest, did you have any problems getting in touch with Bonnie at Xiongda? I tried to email her from two different accounts and both times the messages got bounced. I’d still like to fix my motor if possible.

The first email I found bounced back, but I found another email and Bonnie replied straight away with this one bonnie@xiongdamotor.com.cn she is very helpful and speaks good english
March 8, 20197 yr The first email I found bounced back, but I found another email and Bonnie replied straight away with this one bonnie@xiongdamotor.com.cn she is very helpful and speaks good english Thanks awol, that’s the same address I’ve been using for Bonnie. No idea why the messages get bounced back - I’m using the same email account that I used when I ordered it 18 months ago. I’ll persevere!
March 15, 20197 yr The motor has failed after 147 miles. At first I thought it was the bearings until I opened up the motor and found this. [ATTACH=full]28938[/ATTACH][ATTACH=full]28939[/ATTACH] Have emailed Xiongda about some replacment gears. AWOL. this happened to me. You need to replace the white, dry lube with some good PFET gear grease on one side, and some PFET drip lube on the other. I did this after getting my new gears and have quite a few miles. Been almost 3 years. Look in the endless sphere forum and read what d8veh wrote. Need to skip around - he wrote a LOT.

Thanks for the info, I have often wondered what that white grease is inside a motor.

Any idea where pfet gear grease can be sourced?
March 16, 20197 yr Any idea where pfet gear grease can be sourced? Probably a typo and should be white PTFE grease, which is easily available.
March 16, 20197 yr Probably a typo and should be white PTFE grease, which is easily available. Not a typo. Worse, bad recollection. After 3 years of no problems I forgot the abbrev. Thanks, you're right Neath, and my brand was Tri-Flow. My light drip lube is also PTFE Tri-Flow. I amazoned, I believe...
March 16, 20197 yr Thanks for the info, I have often wondered what that white grease is inside a motor. BTW, pretty sure that skummy stuff your motor came with is NOT PTFE white gear grease. It's sticky, with no resemblance to me of the slick, translucent "white" PTFE gear grease.
