Thanks very much I am away from the bike until Saturday after next, I hope to have time to look at it again (and report back) then.

Managed to do the following: 1. Measure the voltage at controller's battery connector. 27.3V. This is a 24V battery. 2. Measure the voltage on the 5v rail. 4.7V 3. Check throttle signal wire voltage on it's connector while connected. it's the wire that's not red or black on the throttle...

Thanks that's very helpful. I have run out of time today so it may be a week or so before I can get back to this. Couple of things - I disabled the pedal sensor some years back so this bike only runs from the throttle. Also a correction on the 'clunk' - it is a soft thud noise, low...

Right, heat shrink removed (it is unusually thick ). Connector unplugged, also unscrewed the control box panel. Quite a rat's nest of wires, not sure why so many are needed for a DC motor. Several are disconnected. Wires going into axle look ok, they were entering from the bottom after all...

Thanks yes axle cable entry is just outside one of the photos, I will strip the connector heat shrink tomorrow and take some more pics. Had this bike from new, axle hasn't been moved. The cable does exit the axle upwards so may let water in and may have slight damage, otherwise similar to the...

Photos attached. As you can see it's still 24V. Defo pre 2016, maybe 2010. On its second battery, a LiFePo4 24V.

Thanks for the replies. It's a Cyclamatic Power Plus, shiny aluminium mountain bike, front suspension, quite old. Yes it is an earlier version with the heatshrink. There is slight damage to the heatshrink at the front where the wires enter, not much though. I'll remove the heatshrink and...

Resurecting this thread as I now have the same problem. It started as an intermittent motor faiure (lights on but no power). I was convinced this was the red push button on the throttle so I soldered it closed which fixed it. For 20 minutes. Then power failure again this time with an...

pedal assist - I would expect this to apply power in proportion to how hard you pedal but this is not the case on my Cyclamatic power plus or my partners Powersmart or I suspect almost all others. Power is just on while pedalling and off when not. The result is the range is 15 miles with no...

pedal assist Can't for the life of me find out how to start a new thread here, hope this works. I've only been using the web 15 years mind. pedal assist - I would expect this to apply power in proportion to how hard you pedal but this is not the case on my Cyclamatic power plus or my...
