You can get DNP ones from Aliexpress. I have 11T/32T 8 speed ones for £20.
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.You need to increase the speed to make it run cooler. Slowing it down is the worst thing for it.
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!).
The first email I found bounced back, but I found another email and Bonnie replied straight away with this one firstname.lastname@example.org she is very helpful and speaks good englishOut 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.
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!
