Why the shear strength is important in your application?

Ok, thanks for explaining.

Looking at the last picture - the chain is nearly touching the tire. Won't it rub when cornering and tire deforms?

Electrolube ER2074 is a 10kg kit of thermally conductive epoxy. Try contacting one of the distributors.

You have to take into account the power dissipation of those diodes: multiply diode voltage drop (usually between 0,5-1V) with current draw from your packs; so you may get somewhere around 5-20W of heat. Unless the diode has a heat sink and adequate air flow to it, I wouldn't recommend.

Two expensive but very good lights: Supernova M99 Pro (449€) https://supernova-lights.com/en/products/e-bike-lights-45-kmh/m99-pro/ Daytime running lights, low beam/high beam 24-60VDC (75V max), so you might need DC-DC converter if pack voltage is too high. From my own experience, it's better...

Sounds like over voltage/current protection kicking in on regen braking.

Thank you :thumb: , you just made my day (I've been looking for a solution of vesc display and LED lights for a while).

From pictures it seems the new kit doesn't have second bracket connecting rear of the motor to BB. So IMHO they made it worse. PS. That poor sprocket engagement will only become issue on the "walk of shame" scenario :wink:

Cyclone 2-6kW is peak power. With some modification and depending on cooling, you might get up to 8kW peak from these. QS 3K mid... Folks here have pushed beyond 20kW and still haven't overheated it. So far haven't heard any cooked motor.

VESC should be capable of either with custom app or external controller. Custom app running on VESC CPU('s), keeping both RPM's equal, except when steering. Input through ADC or PPM/UART/CAN. Or VESC constantly reporting to master controller RPM/Amps/etc, which then controls VESC's. Comms...

Motor hall sensors give feedback to motor controller (vesc) for timing. Not (servo-like) position you need for your master controller, which has to keep the speed exactly equal. Cyclone motor-specific problem due to it's rotor design, there can be hall signal noise in-between proper hall pulses...

With PWM you'd need some kind of feedback of the actual RPM or you need to correct your steering constantly to compensate one motor going faster than the other.

With QS-mid you'll need reduction, possibly two stages (unless you mean the one with internal 1:2,35 reduction) to get the rpm down, unless you want to go really-really fast. IMHO two Cyclone 3k/4k motors with it's internal reduction of 1:6 would be enough but not sure about pairing those...
