Thinking of off-the shelf bikes as well as kits: Bosch in particular. No bike is worth having for me, if you have to struggle to out-pedal a limiter on a downhill. And how many will kick-off at full power on a steep uphill within a quarter of a turn of the crank, standing on it? Or is all this...

Have you had a job offer from the manufacturer yet? That flexi-self-adhesive covering has given me problems on similar devices, when it gets hot. I'm not totally convinced your lighting conditions are similar enough (comparing the device shadows) to give a true indication of the improvement...

Today I pushed-off the cover complete with bearing from the chain-side of the motor, and the epicyclic gears mounted on the freewheel on the other side. This enabled a clear view of the windings. They've must have gone briefly above 220-ish C to melt the nylon of the cable ties and lacing cord...

Lot of good information here. I just want to add 2 points: Whereas Cu and Al/alloys have comparable conductivities - apart from surface, as mentioned already, they have VASTLY DIFFERENT DUCTILITIES. In anything being shaken around by bikes, that would mean far more risk of connections...

one of my bike-builds came back for some unrelated work, and I noticed the hub motor, the 4.4:1 mxus xf08 was a lot coggier-sounding than the bike I ride most of the time, also with an xf08. So I took it for a fast 30 minute run on tarmac, and what I had been half-expecting happened...

Greetings from southwest England. Been lurking here months. Some at Grin will recognise me. Anyway, time to pop-up, in my guise of a small-scale e-bike converter-builder (amongst many other things). Decided e-bikes was the way to go in the current climate (-change), as every other person I know...
