the kit i put together has problem where the motor only stays on for a second or two and then cuts off, or if i use only partial throttle approximately 1/4 it might stay on for 4 or 5 seconds then cut off. this problem dose not happen when the wheel is off the ground. the only thing i can think it might be is the batteries not putting out enough amperage but i have been assured that they should be able to.
i bought a 1000 watt electric bike kitt off ebay heres the link to the kit

for the batteries i done something slightly dodgy but i think it should be able to be made to work.
i got 3 li-po 14.8v 4000mah batteries off of ebay and wired them up in series heres the link.
