I'll have to get linux stickers for my bike instead. Maybe I should install a hub dynamo and boot a pi zero with my pedal power every time I ride. Linux on my Linux bike.
Not gonna lie, the extent to which the motor, controller, etc. are proprietary is an important consideration for me when buying an e-bike. For example, I would rather have one that can't connect to my phone etc. at all than one that can but requires a proprietary app.
(I also care about things like weird proprietary headset and bottom bracket hardware, on e-bikes and regular bikes alike.)
