I am attempting to hack this ebike motor to bypass all the proprietary stuff and what I'm seeing so far is encouraging

Even if this bike had worked, I probably would have done this anyway because this bike was designed to be controlled with an app on your phone and I'm not about having to use apps to use other things.
I am freeing this bike from the prison of surveillance capitalism
@MLE_online doing god’s work

This is pretty great. Are you gonna write up your method? Or is it peculiar to the one design?
@tomjennings I think it would vary from design to design, but there are some general principles. This one actually turned out to be much simpler than I was expecting. It was just a matter of finding the hall effect sensor wires and the phase wires and getting them connected to the controller correctly.

I need to buy parts from AliExpress. The scotus ruling on tariffs came just in time

@MLE_online it doesn’t do anything about de minimis or postage prices. I hope at least they’ll implement the lower tariff quickly.

@MLE_online I've been holding off on designing/ordering PCBs for the same reason.

@kilroy_was_here @MLE_online That stuff is great and fun, provided that your design isn't too complicated. I grew up in the paint-on resist / resist pen / rub-on dry transfer methods of PCB generation. These days, I'll sit at my PC with a cup of coffee.

Promising signals from the hall effect sensor wires
Nice scope there, lady.

How did you acquire the bike? Is there a “usual route” for these rapidly expiring companies’ products?

@MLE_online Love it, you did a great job

@MLE_online @tomjennings if you can cope with fairly 'lumpy' running at low speed you don't even need to figure the halls out, just get a sensorless controller and try the phase wires in different configurations until it works.

@RueNahcMohr the supreme court ruled he can't do all that tariff stuff the way he was doing it

@MLE_online Thats interesting, I thought the US president has willy-nilly I-say-so on tariffs?

@RueNahcMohr he thinks he does. The court just said he doesn't

@BenHM3 a friend's wife saw it for free on Facebook marketplace and told him to go get it. He didn't know what to do with it, so it sat in his garage for a year before he gave it to me

I did it!! I hacked the e-bike motor!
It's only running off of 36 volts here rather than the 48 it's designed for because i don't have a generic 48v controller, so it's going slower than it should, but it works.
Now that I know this is possible, I will go ahead and order a 48 volt controller and a 48v BMS for rebuilding the battery pack
