    E-BMX fully suspended/75200 vesc/ mid drive 80100 130kv/ 16S battery (surron and 7P - 40t)

    QS90 can run up to 10kw continuously for a light weight build like yours no problem. It's better than all over motors in this size

    inconsistent power from 72v Enduro style ebike

    If your battery can provide 150A and your Controller will pull only 80A, That's perfectly fine! Should Always be this way. It cannot be other way around! Big No-No. The controller I recommend is FarDriver. Check on their website the power levels for your battery but regardless, it's...

    can I run 52v on a 48v BBS01B?

    I have the bbs01b but I run it @66.6v with a 30A external controller. It does Climb anything, Top speed over 60km/h and does not get hot because I use a 36T chainring with 12 speed 52-11 Cassette. I did not implement PAS yet but I'm testing some solutions. For Battery % I use Smart BMS app...

    All Cyclones have a brutal and aggressive acceleration. If you like pure brute force, does not get any better than this FOR THE PRICE. Just be sure to have at least 10 gears cassette with big cog on low gear like 48, 50 or 52T to enjoy the acceleration, have high top speed on the same package...

    Drivetrain Help for an upcoming ToSeven DM-01L Build

    I personally use mostly thottle only, if I want to pedal I would just lower the power on the PAS Levels if that's an option on my Setup :)

    Drivetrain Help for an upcoming ToSeven DM-01L Build

    Try to get as smaller chainring as Possible and as big Cassete as possible. Because you have many gears, you will be able to climb more and have high top speed all in one package without streessing the motor. Just use your gears wisely! I hope you got a 60v battery. Mid drives are more...

    FLIPSKY new 20s 100A tiny controller (vesc based)

    With your underpowered battery you won't, and very likely you will ovearheat your motor. If you can, Sell your battery and motor and get a bbshd, 72v battery and VESC or get the BBSHD with 52v battery and use it stock. Get a small charing on the front because it's a fat bike and you are good to...
