I built a quad motor, 20hp downhill MTB Ebike with crazy power!

I forgot to mention in the video, top speed is about 80km/hr and range is about 30km.

This is incredible - the chain tensioner setup is so beautiful

[@erikjonromnes]

Sick bike, maybe my favorite conversion I’ve seen so far!!! Good job man

[@danielclarke7109]

Awesome! Thank you!

[@eastwood111]

Love it. Great build!

[@Humboldt710]

You have created quite a cool machine. I have a surron but this is way cooler!

[@danielclarke7109]

Thanks! Yes this has been much more successful than my failed Surron build which kept exploding...

[@erikjonromnes]

Was it exploding bc it’s a SUrron or bc of the custom battery and controller setup ?

[@fodaodocs]

Congratulations on the project, it was incredible! Why did you use 12s instead of the 20s that ESC supports? Did she go 80km/h or more? record a top speed video

[@caseyhanas3311]

Absolutely wild and great build! I can't imagine the power, you may consider relabelling the video 4 surrons in one bike...

[@danielclarke7109]

I hate Surrons haha. Mine just about destroyed me. Could never get it to work...

[@wearemany73]

Very nice work 😊

[@DhanGilmour]

Love ya work Dan

[@travisforster6510]

Awesome! Looks fun to ride.

[@danielclarke7109]

It's like nothing else. The short wheelbase makes it really scary. Provided you respect the throttle, it's really fun though.

[@surron_adventures]

Awesome!!!

[@kalef1234]

How much torque is that?!

[@mckirkus]

I'm guessing you synced them up with a CAN bus? Does the VESC Tool show four devices or two?

[@danielclarke7109]

Provided all 4 ESCs are on the same firmware, motor calibration calibrates all four motors simultaneously over CANBus

[@danielclarke7109]

The VESC shows four devices.

[@danielclarke7109]

I plugged the throttle into the TFT display which was plugged into one of the CANBus ports and it ran all four motors at once.

[@Boediprasetya]

If an engineer wants to do something outside the normal... So it's like this

[@EdLrandom]

what's the advantage of having multiple motors?

[@RobertPetrucha]

I'm not the OP but I think it's just the size and ability to place the motors more discreetly. With these small motors he's wrapped them around the frame instead of having a giant 20kw motor sticking out. It's the only advantage I can think of.

[@T-Sav]

Swear i see this on instagram somewhere

[@danielclarke7109]

Yea I posted it to instagram a bit

[@jaleger2295]

Or just buy a proper hub motor, actual battery (not that weak ass lipo stuff) and adequate controller, like a 85250 ubox 😁
