My Yose Power 250W rear hub motor in 700c wheel is marked: "Yose" with logo and 250W. AKM21123095065 = serial no? 95RX.RC250-3628 = (see below) I think this is a rebranded Aikema 95RX - it looks identical. Presumably "RC250" means Rear hub, Cassette, 250W? and "3628" means 36V, 28"? Is...

Thanks Woosh. That sounds great. With the JYT speed controller, levels 1 and 2 are not much use to me as the speed limits are so low that I'm doing all the work anyway. If I can get it changed to current control I might be a very happy boy! I'd like to try it and see how it goes, so I'll see...

Yes, my mistake. My controller, built in to the battery base, looked similar to a Lishui in a Woosh kit I fitted earlier for a friend, so I assumed it was the same brand. I later realised my controller is actually different and not a Lishui at all. Your video was interesting; the speed didn't...

Better and better - no work to do - I like it! So perhaps there was a poor connection after all. If I connect my spare controller and switch the battery on (no display, throttle or PAS sensor connected), I could rotate the rotor by hand as before and should see the full switching voltage? Or...

I've yet to remove the crank and check the axle diameter, but when I do I'll probably fit a new sensor regardless, while I'm at it, and change the BB if necessary. That will eliminate one possibility. Meanwhile, I'm looking at changing to a KT controller and display, which would eliminate any...

Thanks, some interesting comments. Speed cut-off - yes it does feel like that, but very much more pronounced and noisy than the replacement motor, which is only just perceptible and remains smooth and quiet. I'm fairly confident that the 9 pin plug was fully engaged as I was aware of the...

Hi Saneagle, Apologies for the delay and thanks for taking an interest. I have now attempted the tests you recommended, repeated to ensure consistency. Short to case There was no continuity between any of the nine motor lead terminals and either the motor case or the axle. Motor phase wires...

It's nice to hear an alternative point of view, regardless of whether one shares it. Goes to show that everybody and their preferences/requirements are not the same.

Wow! That's really helpful, thanks everybody. Lots to think about. From what Woosh says there are aspects of speed control that are more sophisticated than current control. It would be very interesting to see graphs of current/torque against speed for each assist level, and for each type of...

Thanks Nealh. I'll look into that, sounds relatively straightforward. Would a KT controller work with and (perhaps?) plug straight into a C500 display? Or should I consider a better display? Motor is an Aikema 95RX (rear hub). Do you think a current controller would make this a nice mtb...

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...

Thanks Cadence, I'll bear that in mind.

The sensor case fitted well into the BB splines, no worries there. It was the magnet disc splines that concerned me and whether the magnet disc is damaged. I may have measured the square taper diagonal at a point where it is not the same as the circular part of the axle. I can't see very much...

Thanks Woosh, good point and thanks for the tip. Actually there wasn't anything about axle diameter in the fitting instructions (it wasn't a Woosh kit). I was actually thinking of a different kit (which was a Woosh one) that I fitted for a friend, where this was not an issue. Woosh's...

That's worth checking. I do remember there was something about the axle diameter when I bought the kit so I'll have to review that.

Just remembered: I fitted a left side PAS, the type with a plastic casing that "plugs" into the bottom bracket internal splines. Looks neat and is easy to fit, except that: The magnet disc is inside the casing and is quite a tight fit on the BB axle. The only visible part of the disc is the...

OK. Thanks again.

Hi saneagle, and thanks. No, I didn't fit a throttle and left the two throttle settings set to "N". Could it be a PAS sensor or cable fault?

Thanks again. I like the sound of that although it'll be a while before I get to it, so watch this space.

Thanks saneagle. That would be the best possible outcome. Is there any other way I can confirm that the motor is sound and/or identify and fix a motor cable fault? I have a reasonable digital multimeter. NB Unfortunately I have very limited working space (too many bikes) so it would be...
