I picked up a fairly heavily modified schwinn/currie scooter on craigslist about 2 weeks ago. I've torn it apart, cleaned up his dirty solders and connections, and put it back together. I do not know what model it *was*, but here are the original specs:
24v, 250w chain drive
drum brakes in back
cantilever brakes in front
He added bigger better batteries, so now it's 48v at 10a, and now it has a 36v controller. (he was running it at 36v). It still has a 24v motor.
I'm being very very careful with this setup because I know the controller and motor can't last forever. It's fast though, I'm going to sat at least 30mph on flat with my 190lb frame on it. I melted the brakes on the first real run of 1 mile the other day.
I want to make it bad though, ignoring all safety and reasonable usage, but I'm new to this. I want to know if I attach a 48v 1000w or 1500w controller and a 48v 1000w, 1200w, or 1500w motor if I'll actually see speed/power increase OR if I'll just be less likely to burn it up.
I only need about 5 miles of total range. Really 2 would be fine---but I've got a bunch of steep hills, so I need torque.
Feed me your insight---I thirst for it. (Also installing one of the 80cc bicycle engine motors tomorrow, but that's not an EV...)
