P3PPY said:I took apart the 6V gearbox today and the Power Core E100 razor's too. The motor body is the right size but it's just barely off with the shaft output gear > gearbox input gear (which overlaps the shaft gear by half a mm). One thought is to soften the plastic gearbox input gear with heat; maybe that will be just enough of what I need (to not spend money, that is). I wasn't able to pull the gear off either output shaft; I was going to see about swapping. I used heat on both as I saw on YouTube but nothing. I'll post some pics later.
I'm still figuring out how to make it work with the 3mph kickstart requirement that the stock Razor controller has. Current plan is to get somebody's old gearbox and put it on the other wheel (as it sits it's a one wheel wonder) and give it either its own 12V power supply or see how long it would last on the same 24V I'll be using to power the big motor.
Two questions:
Bad idea to run the 24V motor on 12V?
Any ideas on a simple live axle for these?
A 24V motor will likely be a snail on 12V, but I don't have much more to add. If you're a FB user there's an enormous Modified Power Wheels group that has people way more experienced with hopping up these things than you're likely to find here.
I just got a new controller and throttle in the mail so I'll be digging into one of our SX500 motorcycles soon. Right now top speed is about 14 mph with me riding it, 18 mph with an extra battery connected (boosting it from 36V to 48V). I'd like to see +20mph and a lot more torque after the upgrade from 500W at 36V to 1000W at 48V.
