Given the current unfriendliness of Bafang's CAN bus implementation (and, presumably, the similarly locked-down and otherwise uninspiring offerings by Bosch, Shimano, and others), I'd like my next bike to be a build involving reasonably manipulable electronics. Doesn't need to be compile-your-own-firmware (although I'm down for that), but the ability to tweak wheels, speeds, and assist levels would be really nice. I know my way around a soldering iron, but well enough to know that I'm not likely to spend my evenings designing and assembling PCBs.
What's out there? I see mega-threads on Cyclone and Tongsheng offerings, and there's "always" the BBS02/BBSHD (so long as Bafang doesn't transition those to CAN as well), as well as some discussion of Cyc. What else am I missing?
Some parameters I'd like:
* Mid-drive
* Software configurability
* Light-er weight (under 10lb would be great)
* 500-1500W (higher is fine so long as efficiency is there)
* 48V preferred, 52V acceptable (battery density)
* Frame integration is nice-to-have but repurposing an old frame works too
For example: right now I'm considering repurposing an old Novara hardtail I have to serve as a gravel/light-trail build. Luna's upgraded BBS02 looks nice, but so does the open-firmware TSDZ2 from eco-ebike.com. Does anyone have (or have used) both and can provide constructive comparisons? Obviously weak parts (like gears) would definitely be replaced with more robust alternatives, but I'm not even sure if these are the right options.
