    Killed hub motor on 1st run, lots of friction now.

    latest response: Hi again, I read back previously messages that found you have limited the curent. Can I know the riding environment? Are you using the kit and battery for ebike? What is the weight that the bike carried? What is the temperature now? Take the controller out of bag it needs...

    Killed hub motor on 1st run, lots of friction now.

    i just though that using the supplied bag would be ok in the cold, boy was i wrong. why do they even have it like that, setting me up for failure.

    Killed hub motor on 1st run, lots of friction now.

    well i blew i 2nd controller, its shorting internally again. i bought a controller and motor tester. https://www.ebay.com/itm/24V-36V-48V-60V-Electro-Car-E-bike-Scooter-Brushless-Motor-Controller-Tester-/192496420473?hash=item2cd1ae4679 . the controller was very hot again, i was just keeping it...

    Killed hub motor on 1st run, lots of friction now.

    got the controller today much quicker than expected, everything works again. i limited the power to 80% and disabled brake regen to limit the controller heat. the controller that died was in a bag with no airflow and was still red hot after i pedaled it home, pretty sure i cooked that one...

    Killed hub motor on 1st run, lots of friction now.

    i honestly did not think that the controller shorting internally would make the hear hub act like that, i disconnected the battery and hal sensor plug, my mistake

    Killed hub motor on 1st run, lots of friction now.

    well i disconnected it from controller and it spun smooth, should have done that 1st. blown controller, it was registering just under 2000w. I'm surprised it overheated and blew so quick, it had cylinder fuses with it, or does it need a fet replaced, or just replace the controller.

    Killed hub motor on 1st run, lots of friction now.

    i disconnected the wires and its the same, if there pinched together on where they exit the motor, will it still be rough even if its disconnected?

    Killed hub motor on 1st run, lots of friction now.

    I JUST got my hub motor installed. It was working just fine got up to a top speed of 33mph. For no reason the bike cut out and gives code 06 from the lcd3. At the same time now the hub is very hard to turn, it was very smooth before. I got a hub motor to avoid drivetrain issues but looks like i...

    Optimal P and C values for 1500w motor.

    Columbia 1937 1500w, part selection help

    i was thinking the taller wheel would be a higher ratio and give me some more speed at the same wattage, any battery suggestions, i like lifepo4 because of the increased charge cycles but everything seems to be going to 18650's probably because their being mass manufactured for tesla, and could...

    Columbia 1937 1500w, part selection help

    I think im going to go with the gravity 29er front suspension from bikes direct unless someone has a reason why not. With that bike on a 1500w controller, how big of a battery would i need to get 30 miles at 25ish mph, roughly (im 5'6" 190lbs). I like those street tires and might put them on...
