yes several ISIS crank available for BOSCH or others. But with different offset,. It's seem that if we want to keep the original offset of the M820, you need specific crankarms (in ISIS connection).

You have not afraid that your shunt move sometime ? personally i prefer weld the 2 cables inside the battery

beautiful. only cosmetic skin upp aluminium cranks or more ? how many length, price, availability ?

only position sensor calibration. torque sensor calibration as always fail with all M510 that i have tested

+1. I confirm also. you just need to replace controler on FC1.0 to have motor who functioning as well than FC20 and you can also adjust all parameters for each level with BESSTpro

i don't know for the m820, but if it's alike other M series, it's normal if the motor don't turn when you turn crank arms with wheels in air. It's need effort on torque sensor and you can provide that only with resist with wheel on ground. Check if speed is diplayed on HMI when you turn cranks...

your are not satisfied by the pike ? i find it working well and it's more light than others . what is the size of your tires / travel of your suspension and the BB height (crank shaft axis to ground)

i have ordered one to replace my current system used since several years (+- same but only manual)...

Please can you mention (those who have noise and those haven't) your firmware references ?

ask to your motor supplier (and share it here ;) )

thanks all. solved. simply by ignite the motor before connect BESST (with firmware previously upload on BESST).

they are dedicated to fat bike

BESST wiring does be interfaced between motor and HMI (display), only these 2 connector will be used for CAN bus

320 w in E at max crank arms torque ? it's too high for me. with how many crank RPM ?

yes

somebody have tested if throttle (yellow connector) could functioning on M820 ?

better whith pics to understand

clear. that would mean my motor have an problem to delivery max power. i will try (when i will remount it) with other firmware to check

Ok, i have corrected my opinion and i will check when i will receive my frame. As i seen, The problem don't come frome the wheel size, but at level of articulations of the stays and bases. may be you don't go to full rear shock compression ?
