Hi Everybody, I've been looking at a road bike conversion, but this doesn't seem as straightforward as one might think. My daughter has a Trek Lexa road bike, XS frame size. Thinking that it would help her up the steeper hills around Goudhurst in rural Kent, my son-in-law bought her a...

I have a Lishui speed controller. As I understand it, it gives maximum torque (current) until it reaches a limiting speed according to the "power" level selected, when the current is tailed off by the controller. Hence "speed" controller. I believe a "current" controller limits the current to...

I have a problem with a Lishui controller. At least, I think it's the controller. The supplier is currently sending a replacement, so I'll know for sure soon. If the old controller is faulty, I'd be keen fix it and use it on another bike. All is fine except that, if you are out of the saddle...

A while ago I purchased a Yose Power kit with what appears (from the markings on it) to be a rebranded Aikema 95RX 250W rear hub motor. The problem was that the motor would surge once it had reached the speed limit for each power setting, with the rpm rising and falling rhythmically. This was...

Hi All, Apologies for long post. I have been trying to understand how controllers work, or at least the key principles. I've picked up some useful info from other threads, and especially posts by NealH and vfr400 (=Honda m/cycle?). Thanks to them and everyone else that has contributed. I'd...

My first e-bike... generally good but after 500 miles some issues have come to light. IMHO: The saddle position is too far forward, by as much as 25-30m. The standard suspension seat-post has no set-back and the saddle adjustment is limited. To fix this I have had to buy an after-market...

I bought a Cube Touring Hybrid Pro 625 a few months ago, my first e-bike. I'm an experienced cyclist, into long day rides and touring with the panniers on. This is my first e-bike. Overall it's been good, especially the Bosch motor, controller and software, battery life (if used carefully), the...
