I went for a quick sneaky ride around the neighbourhood, this bike has got a nice bit of punch to it and I haven't even started tuning the controller yet. I'll have to change a few things though, the seat cushion is way too low and thin, and the handlebars are very low, my old back says no. It...

Sucess! So, turns out the orange wire to turn the controller on, it needs the full battery voltage, not just +12v from the dc-dc converter. After that quick little rewire, the controller came to life, the bluetooth started working, the app works! Twist the throttle and the wheel spins, then...

right, progress, yea, that's been happening slowly between everything else life has been throwing at me. The MQcon inverter is non responsive, didn't even seem like it was turning on, damaged internally perhaps. I tried to make it work, but Chinese electronics are going to as reliable as they...

I had to mod the clipon handlebars, the inside needed to be machined out to fit the mirrors and some holes drilled to run the wires for the new buttons. I'll need to sort out some grips then start wiring it all up. Choosing the headlight is going to be hard. This will set the entire look of...

Oh, thats a very nice pdm, its got some good functions built in. I guess at the end of the day, do you want those features or is something a bit more basic going to work just as well?

I did some CAD (cardboard aided design) then transferred my prototype to metal. The front half picks up the 2 vent holes in the front of the frame. It won't need to come in or out to get to the battery, which is nice because its a pain to install. The dc/dc converter, pdm and horn relay...

sorry, typo, should have been 85.8v. That's what my multimeter displayed. But, still, thats indicating that the cells are fully charged to 4.22v, which is still too high for an 18650 cell. I'll have to investigate that as well. Personally, I don't like to take 18650's over 4.1v Thats a good...

as far as I know, its a Li-Ion 18650 cell pack, 20S19P configuration, built in bms

Flexing (and vibration) is the enemy of rivnuts. If whatever you've attached can move or cause the nuts to flex in their mounting, they'll slowly loosen off. If they are spinning in their hole, sometimes you can jam a flat head screwdriver under the lip, twist it for tension then loosen the...

The battery is fully charged, currently sitting at 88.5v 85.8v Of course they have a special usb cable ffs. Do you know what's so special about it? other than it being a male to male cable? I don't have their specific usb dongle either, but from my research i've seen others mention that its a...

https://purposebuiltmoto.com/product/black-box-motorcycle-electronics/ This is the pdm (power distribution module) im using. Essentially it'll replace the whole fusebox and has outputs for all my lights and indicators. I've got a more complex one in my car that replaces the fusebox and serves...

Hello all, I'm having some trouble connecting to my MQCON 72250 inverter. I'm rebuilding a bike at the moment (Suzuki GS500 conversion) but im having some technical troubles with it. Currently I can't get the throttle to work and I can't connect to the inverter to do any trouble shooting...

Hello all. I've bought myself someone elses project and now I'm fixing up some things, improving, putting my own touches on it etc. The bike is a Suzuki GS500 thats been converted with a 4kw hub motor, MQCON 72250 inverter and 84v batteries. The frame that holds the battery boxes was pretty...
