I absolutely love projects like this. I feel like my class 1 Bosch ebike controller is really limiting what the rest of the hardware can do.
On a slightly-related note, I’d also love to replace the Bosch battery charger my bike uses for a DC-to-DC one. I’m usually charging my bike directly from a portable solar panel, and skipping the DC-to-AC-to-DC dance would make things much more efficient.
in that case you would still need a boost converter or buck converter or smps to make sure the input and output voltages are at efficient values.
Make sure you know what you’re doing, especially on the battery side of the DC to DC converter.
Hmm, been thinking about converting my old hybrid MTB…
Is this the first Open Source one?
I’m not sure TBH
I’ve seen other open source ones but not meant for bikes
