@ukuku The controller I am playing with literally today isn't open source, but it connected with my randomly sourced battery and motor. It has the option for input from a bottom bracket sensor. I will be adding one of those once I get the rest of the bike sorted out

@MLE_online I have a couple of working 250W bafang motors and one working battery, but the controller is bad and unavailable now. Been a lot of heartache with this bike. I wish I had your amazing skills!

@ukuku that controller I linked you should work

@DenOfEarth @ukuku @geekmomprojects I haven't built a a controller from scratch, but I am building an e bike using an inexpensive off-the-shelf controller right now

@MLE_online @DenOfEarth @geekmomprojects do you mind telling me which controller you chose?

@ukuku @DenOfEarth @geekmomprojects This one: https://www.aliexpress.us/item/3256806133810521.html

Just make sure you get one that matches your motor voltage/wattage, and make sure it has the right kind of connector for your motor.

@ukuku @MLE_online @DenOfEarth I'm afraid that I don't do a lot with large motors. The only largish project I ever built was this self- balancing scooter (https://www.geekmomprojects.com/the-halfway-a-self-balancing-scooter/) which used a Sabertooth 2X25A controller. I agree with Emily's advice to match the controller to the current draw of the motor, but don't have much more to offer on the topic.
