That's right. You've learnt everything bad about those cheap kits. I always advise that it's worth paying a bit more to get a kit with an LCD. The Yose Power kits do indeed come with a sine wave controller. They're excellent and more or less silent.
I've had the new rear hub kit for a few days now and i have to say it's really great in comparison to the cheap non lcd kit i tried.
It feels and sounds far better now which actually makes it enjoyable to ride again. Has no trouble getting up hills and even the more tiring country roads around here.
I do have a few questions though hopefully someone here can answer.
Is the pedal sensor meant to be tightened all the way up so there's no gap because i was worried it will break?
The arm isn't really on fully id say its about 80% or so but seems secure enough though im not sure. The sensor has a little plastic ring with gaps that looks like it will go inside a bit but again im not sure if it's meant to or not so its up close but not entering inner ring.
Also the disk break isn't quite centred between pads so it rubs very slightly and doesn't break fully. I had trouble getting the wheel on and im not sure if the spacer/locking bit is meant to be inside pointing out from tire or inwards?
I appreciate any help and am also wondering like above if Ah makes a difference to just distance or power output as well?
You can smooth out your present motor and get the 5 different PAS levels if you just change the controller to a Kunteng sine wave one, which costs about £70. You can only do that if you have a sensored motor (3 thick wires and at least 5 thin ones).
I wonder now can i use the new kit to test the cheap hub... I guess id need a connector with new and old style plugs?
