I think you're misundersatnding. Say there are 6 speed sensor magnets in the motor. You set it to two in the LCD settings, so that it shows 1/3 of the actual speed on the LCD. It looked like the owner of the bike got something wrong in the settings and set it to read double the actual speed.I guess if the motor assist speed was limited to 15.5mph that would cut in when the indicated speed reached 15.5 mph, regardless of load
Are those two batteries on the bike 36V and are they in series = 72V? They appear to be connected to the same bag. This bloke did the same sort of thing (I had nothing to do with this video), but can also switch them to parallel. No Schottky. The high amp rated switches were from an old army radio.that motor looks far too small to ever be able to drive the bike & rider at such a high speed.
Thickos spelt "committed" wrong. Dumb for a public announcement.PS10 is public safety.
no the controller would melt at that voltage and that motor is tiny so prob 250w but if set to max with two batts that size be lucky to hit 20mph.Are those two batteries on the bike 36V and are they in series = 72V?

Could have put them in series, with a controller for 72V, but even then, max speed would only be about 33 mph for a standard wind motor. Maybe if they had put a 20 inch motor in a 700c wheel it would go a bit quicker...but looking at that wheel, it's not spinning fast enough.Are those two batteries on the bike 36V and are they in series = 72V?

A standard motor is 260 rpm, so at 72v it would be 520 rpm, which is 39 mph in a 26" wheel. With two charged up 36v batteries in series 43 mph would be about right.Could have put them in series, with a controller for 72V, but even then, max speed would only be about 33 mph for a standard wind motor.

Yes, for no load speed. I didn't make it clear which one I was talking about. However, I think we're agreed that the wheel in the video isn't going that fast.A standard motor is 260 rpm, so at 72v it would be 520 rpm, which is 39 mph in a 26" wheel.
