    Halled motor cogging on start up, what could be my issue?

    Its a hub motor (scooter, sorry) and i get a strong cogging on start up as seen in video. No load, no cogging, Light throttle = less/no cogging. Soon as the motor is spinning the cogging is gone but i feel as though its not running perfectly as it has a slight hesitation from a roll on. What...

    Dual hub motor E bike vs single motor mode, which is more efficient?

    On a dual hub motor bike, i have two questions about efficiency. Is it "bad" to run ONE motor at a time (bad for the non running motor or controller) if so, why? Is it more efficient to run both hub motors vs one, or the opposite? Which will provide more range?

    Parallel battery for extended range, is it safe?

    Long story short, Is it safe to run a different brand battery (both 18650 60v, newer packs, each have BMS in casing) in parallel for extended range? If so, is it possible to run just ONE pack when needed or both when range is necessary? I can think of how to wire it up but i just dont know if...

    FFR - Horizon motor swap

    I swapped the motor on one of my Fluid freeride Horizons with a T9/zero 9/apollo city motor and it's been great so far. Speed went from 22 to 29 on flat ground, up to 33 on a slight down hill with a lighter rider and the pneumatic tire gave it a lot more stability and braking power (one rear...

    Mantis 10 Pro - Has anyone modified one to make it faster?

    Do these circuit boards look the same?

    I replaced a hall sensor circuit board and sensors and my motor is still not working so I'm guessing the board might not be the right one or possibly the hall sensors are the wrong variant. Either way, I tried sourcing the OEM board and I can't find it anywhere. I'm wondering why I still have...

    How much battery capacity is lost annually?

    On average, how much battery capacity is lost every year with a ebike lithium ion battery? What if its stored properly every year for a few months and kept indoors? How many years can I expect out of it?

    Whats going on here, serious voltage drop?

    When I'm on power, the voltage is all over the place. If I take the scooter for a drive, it will go from 5 bars to 3 on the battery Guage, when its fully charged. Its a Zero 9 52V 600w scooter. https://youtu.be/zyMtz7cEKlo

    How to delete a speed limiter on my controller?

    I know it's not a bike, but I am tinkering around with a scooter (Schwinn Tone 3) and its currently limited to 16mph. I can reach 16mph on flat ground fairly easily and when I pick the scooter up with no load, it will stop at 16mph so I would assume it's limited with the controller, correct if...
