- Idea was to monitor motor temperature, then I have added also other monitor parameters: Speed, Energy consumption per km, Voltage, Current, Power, Used energy over coulomb counter (SOC should be more accurate), Temperature of stator windings and controller.
- Also can easily setup max assistance speed, wheel size and circumference.
- Rechargeable battery (works cca 8h on one charge, or can be run also from USBC).
- After unlocking no need to have installed device on an ebike
- You can still put back original speed. Bafang is not loging this, so in a service wont notice.
- You can change wheel circumference if not accurate against GPS speed
- Check youtube links how it works - very simple, just few clicks.
- No need to buy BESST Bafang programmer and have trouble to get password.
- No need to cable motor to computer.
- You can unlock Bafang motor to your friends around you

Hi Dado

So you know I have received the K1 CAN Monitor and it works really nice!!
The buttons are easy pressed with my finger

Thanks again for the service and have a nice day

K1 CAN Monitor is determined for testing purpose only. Device is not waterproof.
One disadvantage - small buttons - you can get used to it or use pen if you have big fingers.

That should be popular! Good job

Should this also be able to be used with the M800 series motors?

Yes, also with M800, as far as I know new versions of this motor are also CAN bus.
Few microcontrollers should be with me on 12.9. and I can ship.

I bought one and like it a lot. Unlocked the top speed in half a minute but still use it here and there to check temperatures on some of my rides! Very cool device!

Thanks mate for kind words and review. Yes, that was my intention to make it simple. To avoid messing with Besst, last time Besst was not even compatible with BBS02 motor and recently my password for Besst was blocked.

Only that small display, will try to design and code bigger display in future.
