I put together my first ebike, Specialized SX trail. I had bought a BBSHD but it doesn't fit this frame as the BB has too much reinforcement. I had a cheap Chinese 48v 1500w rear hub kit and 48v 14.5ah battery I had grabbed off craigslist and I'm really enjoying this cheap introduction to ebiking.
I bought the kit new in box, but off craigslist so I'm not sure exactly what kit I have - there are no specs or "brand name" etc. Can anyone tell me how many amps I'm probably sending to the motor? I'm assuming 20?
I've read these hubs can take quite a bit of power. Can someone give me a suggestion of what specific controller would be a nice upgrade? I was thinking of 35 or 40amps would really wake this bike up, giving more torque/speed for quick bursts. I won't be doing long hill climbs or going WOT for miles at a time so I'm not too worried about ruining the motor. (plus it was super cheap)
And maybe a small capacity battery that can provide 35-40amps continuous? Most of my rides are just exercise rides after work half hour to an hour. I would think a 10ah battery would be plenty, but I can go bigger if you guys suggest it?
Would you guys stay at 48v or does something else make more sense?
Thanks in advance.
