Yeah it's different for sure but it's coped fine with it on steep rocky ground as well which is a lot of the riding now, unlike my SRAM chains which don't last long. I think the reason we can get away with it is because even if only designed for a bike with 400w, a person pedaling can produce a...

I've used the stock freewheels for about 2300miles and on 48v never been a problem but I did eventually snap one tooth while running 72v so I think it's a little too much power on 72v but never any problems otherwise and I usually accelerate quickly.

3.85v per cell

I would say it's very roughly the same loudness only at 72 it's much more of a high pitched sound - more annoying - so feels noisier. I don't think it's big problem at all personally but if you only want 27mph top speed then may as well get 48v as it's less noisy and should have the power. I...

Yeah I guess if the ebrake isn't very reliable itself it could end up being more dangerous due to the reliance. I have the battery XT90 just over my shoulder so can just yank it out if anything goes wrong.

When I have my bike it a low gear on max rpm and squeeze my shimano hydraulic brakes the wheel keeps moving- I actually couldn't stop the motor! So much torque. So yeah it's safer to have ebrakes but it's not needed. I ought to get some ..

The red wire has to connect with the main battery positive but I can't remember where the battery voltage wires go. And the 3 throttle wires on the controller red black and green can be connected to any 5v throttle. (red being positive 5v, black being ground, and green being the throttle signal)...

I have briefly tried it with my em3ev thorttle. I think any type should work as long as the on/off wire is connected right,

A throttle with cruise control can help on bumpy terrain, but it's not safe. Needed to train myself to disengage it super fast

A bit of both I suppose :?:

There are so many ways to get a stiff mount, one may be the the strongest but others can still work :) I haven't actually shown mine here but it's different to all others, still works fine even if it's not the best one. Shame there's all this conflict on technical stuff when we are all in...

Yeah maybe so. there's the 36-60v that came before the 36-72v so i guess there were some upgrades. On my bike 48v is fine for use most of the time 72v is just for fun rides :D

I guess maybe it just depends on the rated voltage of the 5v step-down reg then. I agree it's best not to push it i've had two blow many miles out, wasn't pleasant... (not even overvolting it)

I've always wondered as it's usually rated voltage of the capacitor and FETs that's considered in maxing the controller voltage, surely there's other little regulators etc to worry about as well?

One of the main benefits of a sine wave controller is actually better efficiency. If I remember right with a standard 3 phase controller highest efficiency can't exceed ~90% but with a true sine wave it can 'theoretically' have 100% efficiency. Which obviously isn't going to happen but still...
