My ebike is a freak in itself. I really do not have to charge my battery for two weeks. I made it three weeks the first time I got it. My single battery is actually made up of 8 different batteries. Hence it can go up to 80 km.
It is a pain to take out though. I have to unlock a chain and then unlock the actual battery lock. Then I will have to carry this heavy thing to my apartment. I am a weightlifter so when I say heavy, I mean heavy.
It normally takes about 4-6 hours, so far, to charge the battery. Then back downstairs to put it back in the motorbike.
