do yopu build you batteries in house?

you can also do stupid things like program the controller if you dont want to go top speed all the time. his advice is good but not everyone wants to spend 1500 on a battery so its nice you can program the controller to your batteries capabilities.

i have a few of those frames and have one set up with a 10s24p battery......so thats about 80Ah capacity

i currently run dual DD motors on my bike and both have different wattage ratings. i also run the weaker motor in front. ive never had any problems with the setup. yes the rear motor does most of the work. not sure why salvatore says it causes more resistance? if you looking for more power you can upgrade your controllers all you want but if you have a battery that only puts out say 50amps thats all you will ever get. more voltage gives more "power" only because electic motors spin at a given rpm per volt up to thier maximum rpm. i live in a hilly area and find the dual motors the only way to go with lower powered ebikes
