Re: Speed Record has to Go somewhere

Riding along at high speed on a two wheel trailer while hitched to an 8 cylinder suv is a death defying stunt. No doubt.

Cycling purists might be offended. :lol:

Re: Need help with building 1 24volt lifepo4 pack or 2 12volt packs

Well for 24 volts you would want 8 cells in a row, and with 40 cells you can go with 5 in each parallel group.

Re: 52V to 60V - Please Help

Amp hours AH, refer to battery capacity like how big is the gas tank in gallons or liters of fuel. At a 1c discharge a 27ah battery should deliver 27 amps of current for one hour. A 10c discharge would be a draw of 270 amps and drain the battery in 6 minutes or less. A motor will run on whatever vol...

Re: Help,911 ...was riding in the rain and

A rough feel from the motor when riding is usually one of the phases is not contributing any work. Check all wires and connectors between the controller and the motor for any problems.

Good luck

Was a good chance to see other styles of ebikes and meet the riders.

Made for a good afternoon.

Re: Urgent! Can I ride home on shorted phase motor?

I suspect that your motor is ok. Continuity between all phase leads is a good thing. If 2 melted bullet connectors were to touch each other that would make the motor hard to turn and it might just damage a fet in the controller.

For an 18 inch steel mc rim I use 10 gage spokes in a 2 cross pattern.

For a 16 inch rim you might consider a 1 cross pattern, maybe even re-drill the hub flange to get the spoke angle in the ballpark.

Re: Front hub thousand-watt bad

Yes well a permanent magnet motor will act as a generator when spun up. So if the gas motor is driving the bike at 30 mph and the front hub motor is a direct drive motor then that front motor is generating juice. A guess from here is that the hub motor generated a high enough voltage to damage the f...

Those volt readings do not look well balanced to me.
I will balance charge my rc lipo packs if they get to be near .1 volt of difference.
