Hey guys, I don't want to flood the Zenbikes forum for Supernova - but here is what we will be using. This is more gory when laid out like this but rest assured that the final wiring will be a lot cleaner.
1. All M99 Pro versions come with the sensor (I have highlighted that part from the official documentation) which does motion + light. It also toggles to high beam (if dark). As you can see from the second picture, ours is pure "power only" circuit.
2. You can see that on the picture below that the light (the bright thing in the middle) is on (I had to shake it to induce "motion"), it is connected to the brakes ( in the white cloth), rear light (left) and horn (not in the picture) all connected and all work. Let me warn you the horn is frigging loud.
3. My only issue is that Supernova uses like 22AWG wire for a 60V battery output. That is not ideal but Supernova has stressed that this is safe since the light only takes what it needs, so 22 AWG should plenty. Looks like the same setup is being used by multiple non-Bosch motors so they have a fairly reliable track history for this.
4. The whole setup works with minor quibbles of too much wiring (no kidding). Supernova adds 3 cables to the whole thing (2 on the light, and there is a splitter to support brake cut offs, and tail lights). We can hide all cables in the new integrated downtube, so I am not too worried about that - its just that it will take a little more assembly time.
5. So far we have not needed to rely on the CAN protocol. May be once our display is available, we can communicate using BLE and turn off with the bafang toggle!
lol. Wouldnt that be nice.
6. We can add a toggle to the supernova on / off. That is not a problem.
If any of you have worked with a nicer higher quality toggle, let me know and I can test it out. I am trying to get to a cleaner look.
