I forget if i alluded earlier but the reason for this is i want like 200 mile range ebike at 25+mph, which is not possible without a generator. also, a engine powered bike is illegal in my state so i had to make a hybrid.

its a little slow at 25mph, so i am gonna series another a123 battery pack and switching supply for 80 volts which should get 45mph for this hybrid.
Last year i ran 2 a123's in series and did 45 without the trailer and gen, so i expect a speed downgrade to 38 or 40mph cause of the extra weight.
the generator is 1800w running which should be adequate i think for 40mph with the batteries to make up the difference. i am gonna order a 1800w boost converter and my SMPS power supplies are 2 x 1000w = 2000w.
what is the wattage required for 35 or 40mph, wouldnt 1800w work, i know its probably 1600w after efficiency losses.
