Hmm, interesting. Will look out for that, thanks.

Well, just jumped into the deep end and ordered a High Voltage kit w/ BAC855 controller.

*Technically not “Version A” with the Anderson phase connectors, but the older B version with the rotor which still had the issue of breaking. Circa mid-2016.

No it’s actually version B. I have an original version A too. I‘ve actually since swapped out version A windings into version B motor housing and reinstalled version B rotor (so bottom bearing size matches and still maintain strength of version B rotor). Working with no error codes so far, but...

Hmm…42T chainring (lowest I can go for chain line offset) with a 50T 1st gear? Should spin up fast. Looks aluminum and not steel though. Of course rear derailed not spec’ed that large but see people using an extra long B screw. Starting to understand how this motor works (the hard/expensive...

Also, FYI tested it on bike stand. Would run wide open for 20 minutes (or more) under no load with zero rise in temps of case (controller or stator side). I obviously bogged it down in too high of a gear under load to fry windings like that. So it can handle the current, just not heat/stress/low...

Well, very surprised by that. Thought battery would be weakest link, not core. Did that with original nylon gear as well, which I thought would be somewhat of a buffer. Lessons learned I guess. Looking at heat sinks, fish tank temp probes, potentially a larger/wide-range cassette. But….it was...

Efffff

Not sure how strict rules are where you are. Could always use a big Nalgene water bottle holder to cover up. I don’t have experience with anything other than the HD, so can’t give an opinion there. The newer HDs are made very well, just bought a motor core after having one since 2016.

I have one on the shelf, plan to install. I think a lot of people do just fine with nylon gear if you don’t abuse it. I’m trying to run more power through mine and believe it is the heat that causes nylon to fail. I don’t think it is ceramic FYI (not completely ceramic at least). I think it is...

Argh!!! I actually have one of those on order, was hoping the Lekkie had a better bearing. But interesting, need to break out my torque wrench and see where I’m at.

What have I created?! Soldering job was less than perfect for sure, likely used more solder than needed. Perhaps increased resistance even more? This is with programming set at 30A (theoretical 60A). Display is only reading 0.5A and maxes out around 4A during acceleration? Again, under no load...

Temporary mockup with amps set at 27 (x2 with shunt), new motor core w/ new mosfets and rotor. 61 mph bench test under no load…surprised battery could support. More testing to come…
