So I got one of these. They were rentals at one point so the “brand” is unknown. They were called Zebras. The company went under so getting help to do anything is impossible basically. Because the brand is generic, shops won’t work on it. Anyone here able to tell me how to mod its electronics? -remove gps without it making the bike unrideable(I suspect that was a security thing that would make it stop working)-mod it somehow to allow for more speed (caps at 25)-and in general I need a better battery so advice there too
>take out all control electronics>replace with a VESC driver of whatever current range this thing might have, presumably the basic ~60A 72V driver can handle it>add more better battery>???
>>2890187Pretty sure it’s been manufactured by Niu, probably an n1s with modifications. There will be a type sticker somewhere on the inside.Anyway the problem with these is that the motor speed controller and gps and the remote starting etc are usually built into a single PCB to prevent theft, and you may have to replace that entire unit to get it to work, and add an ignition key switch as well.If you can get the controller out you could find a Wuxi Lingbo that fits your model and doesn’t have the gps stuff. Some say the original one can be flashed over RS485 to remove the speed limits and gps lock but I haven’t seen anyone online demonstrate it
Op here, all of those things are well outta my skill range and would prolly have to ask someone who works on what could be this (model) and thx for that potential clue, but like- what kinda professional would I need? Like a guy who mods and does computer shit? Cause it sounds like I’d have to rip out everything until basically all it’s functions are just: if power- then throttle- move forward. I mean all the other basic shit too, speedometer, brake/signal lights, etc. Y’all know of nny website/places where people work on ev bikes?!
>>2890242All you gotta do is connect 2 cables from battery and 3 cables from the brushless motor and 3 cables from the throttle and 2 from the brake and then run the vesc setup tool and done. Time to git gud.
>>2890245I may have just enough skill to do that with some research.. thx anon
