Quick update. I have had quite exemplary service from Yose power. After ordering the new sensor they said they would send me both a sensor and controller, tracked from China via TNT. They also refunded the price of the sensor there and then. They asked that I test both the sensor and...

Yep, you could be right. I've just ordered a new sensor, so I'll soon know;-)

Thanks for the reply. I checked over the PAS sensor and connections before when the original fault happened, but I suppose I can do so again with the crank off. I'm pretty sure that the outer ring of the sensor is well fixed to the bottom bracket and the inner ring is a good fit on the axle...

Alas, after about 150 miles the cutting out problem is much worse. It cuts in and out constantly, for about 5-10 seconds each time. So the PAS is now pretty useless. I had to get home by holding the throttle on for assist, which is a pain as it pulls too much current and makes changing gear a...

Thanks for all you replies. The stuttering has returned a bit, so I might play with the settings. Today it would sometimes take up power after pedalling then cut for a second then come in again. I'm getting used to giving it a touch of throttle to get it 'over the hump' and then it's ok. I...

Thinking a bit more about this, my bike is mainly used for a 10 mile trip which saves £4 on the train fare. Using the higher assist, I can do the trip easily in 45 mins, which is about the same as the total train journey time. If I charge the battery daily, and it lasts for 500 cycles, then I...

Great, thanks for the tips. Good to know!

The problem appears to be solved. First I checked the sensor connector - seemed fine (3 straight, shiny pins). Secondly, off came the sensor itself. When I turned the inner ring, the power came on within 1/4 - 1/2 turn. So far so good. Next I gave the axle a wipe in case any Copaslip had...

I don't think there is any gap to adjust with the KT-V12L PAS sensor. It's an integrated unit. Adjusting the settings might be worth a bash though. Thanks for the tip!

Hi - thanks for your quick feedback! Yes, fitting the bottom bracket was a faff. I ended up bodging on a £10 Halfords bottom bracket with a (slightly mangled) Shimano alloy retaining ring. The steel ring with the Halfords part looked much better, but didn't fit very well and allowed me to...

Hello, I am new to ebikes and this forum. I have just installed the 350w Yose power rear hub motor kit, with 13.5ah hailong battery. First discovery - no controller! After a while, I realised that it was built into the battery base plate. Yose Power really ought to update the instructions...
