Very curious to hear how noisy this ends up being :)

Thanks, 22s would be great. Perfect for running 4.15v per cell.

Interesting about the firmware, thanks for letting me know. OVS is maxed, with a speed limit of 110kph set in case I'm spinning the wheel without load. Battery and phase values are maxed, but I can't recall their values. I'll check that soon. I seem to recall the FET temp values were all...

I'd really like to know how hard the Max-E can be pushed before stuff starts popping. Has anyone here gone beyond the factory max values? I was considering liquid cooling the FETs if it means I can get more juice out of it. I'm fairly light, so my Cromotor still doesn't get hot even with every...

Yep, time for him to contact Tench and finally get an axle that isn't Chinese ultra-low-grade crap :)

Ti axle, CNC weight-loss program... I think you've won the award for "most improved" C-lyte hub motor. Would be even better with holes in the side-covers. More weight to be saved! ;)

There's also at least a 1 second delay on power-up before many DC-DC converters output anything. Might've been enough time for the controller to see an "ok" low voltage throttle signal, then it shot straight to around 5v.

Did you get 26" or 24" hookworms? 2-ply? They stopped making the 24's a while ago, they're becoming very rare. Best bicycle tires I've used, but I'll be sticking to motorcycle rubber and tubes from now on. The crappy thing is that 24" downhill tubes are also becoming rare. Much of the existing...

By the way, most controllers require an input voltage between 0.8-4.0v ish. Yours was probably working ok. Your top speed at 72v could've been correct too, depending on wheel size. For more speed you'd either need to up the voltage or set an overspeed option in your controller settings.

I'm a bit unclear about how or why the DC-DC converter is involved here. If you have nothing but the controller hooked up to the motor + a hall-sensor throttle, is the wheel still hard to turn?

Yeah, sounds like the phases are shorted somewhere. Is the motor still hard to turn if you unplug everything from your controller and the motor wires aren't touching each other?

BMX cranks in small sizes can get pretty expensive too, and you'd need to order from overseas. Unicycle cranks come in any size you want, and they start as cheap as $15. Standard mounts, ISIS, etc. http://www.municycle.com.au/View.php?action=Page&Name=Cranks Not sure how much that helps, but...

Well, I'm aroused. Can't wait to see this thing on the track.

Epic bike, looks like so much fun. I also can't believe that rear-wheel holds up. Anyone that's ridden this thing ever slammed in to a bump/pothole by accident? :)
