Hi all... new here, thought I'd post a pic of my Schwinn:

That sounds like a carbon copy testimony that I would've gave. I could only do about 27 mph on my 36 volt system though. Buying batteries just got old and more expensive each year for some reason. What amount of AH's and weight are you hauling around on her?With this motor (Chrystalyte's fastest) and running on 48 volts, it tops out at 35mph. Still easily has plenty of torque to pull right out from a stop. So I never pedal unless I'm trying to save batteries.
Riding really hard, I can probably drain the batts in 5-6 miles (full acceleration stop and go), but normal is more like 10-12. Slight pedal assist on take off, moderate speeds, 15 or 20 miles ...estimated... I never ride it easy.
How many watts was the motor rated for? Should be able to come up with a comparable HP gas motor that way. Mine was a front hub 650 watt (which is just shy of 1 HP) with a 60 amp controller. I believe my 49cc 4 stroke would easily outrun it from start to finish. Trimming 15 lbs off the bike also helps.Been a while since I thought about it.... 20 AH seem right? I did think about keeping both electric and gas.... always wanted to build my own hybrid
But this is another part of my thinking about gas... with the sensible and cheap sealed lead acid batteries the power system is about 80 lbs I think. Lithium doesn't really save much weight if you have enough batt. to live up to what this motor draws.
Gas would be lighter. But I don't know if I'd be happy without the electrics torque on take off. I haven't had a gas motor on a bike before, so no way to compare.
Is that what the controller is rated at, or the motor itself? I know I said my controller was rated at 60 amps (@ 36 volts), but the motor could never use that much, unless it was under locked rotor conditions or had a short or something.This is a 48 volt / 40 amp system = 1920 watts. So I would need a fair amount of motor to match the power. And a lot more to match the torque, I'm thinking.
