its very simple. these things are stupid easy. one gps, quickly removed behind basket. i literally had a $7 350 watt chinese controller laying around from an old project. the controller that was in it looked almost exactly like it. i swapped them out and that was ALL i had to do. why knock yourself out? if you're going to go through the trouble of aquiring one why give yourself the headache of hacking it? you can get a controller off wish for 10 bucks and you're DONE. i threw a 48v battery in that puppy and im doing 24 mph and pretty much converted it with my eyes closed. adding a 2nd battery tomorrow for longevity. so far my longest trip before the battery died was 20 miles at pretty much full throttle. the 16" tires kick ass. my only remaining tasks is adding a dash for monitoring and getting the lights working. that. is. it.

hope this helps.

I was going to look into the serial info... You claim that just shorting one of the data pins to ground will do the trick?

Read up on overvolting, caps are rated at 63v on most of the controllers you can find.
So you can run up to 58v safety and increase speed pretty considerably. I have had mine going about 26-27
Do you have any info on these machines? I have access to a lot of them... but I am stumped by the gps passthrough control. .I am about to get a serial connection to the device ... wondering if you have any tips or tricks for this one .. .I am expecting the new off the shelf controller to he here on Monday, so I will make it happen then .. .but would be good to be able to by pass the sit down razor scooters ... the ecosmart metro share version...


Let me know what was done on your end .. .I think I am about to crack it .. .just need to know what comes down that data cable ... on tx one rx ... if I can emulate that some how ... I am golden.
Whoa buddy you're getting ahead of yourself. You need not worry about the data connection if you just want to bypass that ole narc box. Get a multi meter and start measuring the voltage of the wires coming up through the neck. Find the high voltage one 36v and mark it and then never touch it especially with ground. Then probe around and find the 4-5v wires. Oh you'll have to cut the connector off to do this save it for that off the shelf unit. Anyhow, eventually you'll have a couple wires with positive voltages , mark those. Now test continuity with a known ground which should be black. You'll find more than one. The rest are data or signal wires and one of which when touched to a low.voltage wire you'lr controller will turn on. YAY that's the biggest hurdle! Now it's just a matter of finding with signal wire is for the throttle (use any 5v and grnd combo will do and the other remaing signal wire will be for the brake. The high voltage wire to didn't touch is for the light and you will need a mechanical switch. Have fun fella if you can make that work you are 99% ahead of the."uuuuuh I fried my board because there are six wires when youn saaidt there were five! It's difffrunt!"
