Re: New Scooter wont start

Check the connectors, unplug each one, make sure everything looks ok, replug. If that doesn't solve the issue, check for connector continuity. https://www.youtube.com/results?search_query=multimeter+continuity+test From there http://www.ebikes.ca/learn/troubleshooting.html this page is likely going ...

Re: Torque Arm missing - is this a problem?

A torque arms function is to resist the torque or twisting forces generated at the dropouts through the axle. A bicycle dropout, especially front aluminum ones, aren't made with withstand the rather large amount of torque generated by an electric hub motor. The torque arm reinforces the dropouts so ...

Re: Throttle sensitivity

Tried using the throttle switch on the "low" or "50%" setting, that only seems to limit the top speed. I think you might want to explore the three speed switch a bit more, it works differently than you may imagine. When you have a switch set so the throttles maximum is 50% throttle, that means that...

Re: Steel frame with V brakes, or Alum frame with Disc brake

The main down side to rim brakes is that they wear away the rim itself. Another, perhaps debatable, down side to rim brakes is they may not perform as well as disc brakes when wet.

Re: Steel frame with V brakes, or Alum frame with Disc brake

Chances are the 8 speed freewheel is coming in contact with the inner portion of the dropout. Usually when I hear about freewheel compatibility for hub motors 7 speed is usually what is noted. Freewheels with different gear counts have different widths. So the 7 speed notion sounds likely to sort th...

Re: motor runs fine then stutters after riding for a while

Check the connectors for bent pins and signs of corrosion. Unplug all of the connectors, inspect, and replug them each a few times. Replugging the connectors generates some friction between the contacting surfaces which might help wipe away any corrosion and help maintain excellent continuity. Make ...

Re: New Kelly FOC controller series

ERPM is electrical rotations per minute. The wheel might rotate at 2000 RPM or something like that, but the motor is performing an ERPM much higher. ERPM relates to two other things so far as I know, pole count and reduction ratio. Perhaps a mac has a reduction ratio of 5 and 16 poles. I could be co...

Re: What voltage FETS for a 72V (nominal) ebike?

There is no correct general answer for various unknown random controllers. Some might guess 90v, but the right answer is it's wholly dependent upon components like the mosfets and capacitors used within the controller. They have a voltage thresh hold, exceed it and the component breaks. Someone coul...

Re: Definitive Tests on the Heating and Cooling of Hub Motor

Placing heat sinks in between the flanges of the motor should be an easy mod that most people can do on their own, as it does not require any special tooling. A good adhesive and you should be golden. The heat sinks would be pretty well sheltered between the flanges and with ferro fluid inside the ...
