Hi im new to this site.
I built an ebike from a specialized hardrock 2000. Its chain driven and has a 250watt motor (MY8029), with 2 x 12v 7ah lead acid batteries in series.
attatched to the motor is a 5 speed free-wheel sprocket. its smallest gear is connected to the largest of the actual rear wheel.
the torque is really low it doesnt feel like i get much of a push. the motor on its own cant even push at 4mph.
im thinking of moving the motor to the middle of the frame and connecting it to the chainset so i have a higher gear ratio so hopefully more torque.
Im really disappointed at the motors performance. when the wheel is lifted it reaches speeds of ~600rpm. it ony gives me +2mph to my normal cycling speed.
Thanks everyone for your help!
ive dropped the sealed lead acid batteries a few times so im wondering if that might be causing a problem. i did order new ones that should arrive soon.
