   maybe not only weight but technique. thanks ladies.

   The “torque” motor will be absolutely equivalent to the “speed” motor at a higher voltage/less phase current. The “speed” motor will be absolutely equivalent to the “torque” variant at a lower voltage and higher current. How much “more” depends on the ratio of the wire turns on the stator.

   So, it’s generally better to buy a “speed” motor because it’s easier to rise current than voltage, unless you hit some limit (bms, controller).

   10Ampere hour mean, that the 10 amp total could be drawn at a 20 hour discharge, theses batteries just cannot do that at all, if you want to draw 10 amp (36v) so 360 watts, you need something like a 200 amp battery, these cost minimum 1000 $ in the lithium adn weight about 60 Lbs. And also if you wnat to push 360 watt on your motor, you need a motor four time the power so, 1200 watt (Real watt, not chineses watts)

   Are there any more powerful batteries available than the 10Ah shown?

   Hi, thanks for the video, but I agree that the test is…unscientific.
   You should have only 1 driver with both bikes and a timer…furthermore no peddling.
   Test at 36 volts then at 72 each….I am assuming of course the bikes weigh the same, and the driver should state her weight.
   It is important that both have digital meters and heat sensors to see how you cook the motor.
   It was a nice attempt to demonstrate the practicality of going 72 v

   i dont get it how a 600w motor holding up so much electricity ?
   how many amps did the 72v setup draw at steepest part ?
   how much you girls weigh ?
   so i can get a 72v-40a controller for a BMC 600w motor and it wont fry it ? (if used for short distances or long?)
   maaan thats cool info you ran here !
   did you have any fuse in the circuit ? if yes then how many amps is it ?
   do you know/astimate how many amps will fry this motor ?

   i like your ride a lot better than the goverment motors(GM)chevy volt.who wants to pay 40 grand for something that makes a pinto look like a caddy?your ride is so cool.

   the world needs more people like you and less people that throw sticks at people like you.

   have you seen the lincvolt neil young is working on?its on youtube check it out.

   many thanks to you and people like you for trying to make the world a better cleaner place.

   hi! ladies , nice ilustration on the 72 volts put a extra swich that eliminate the controller to go direct that will give you an extra boost. nice gob.

    Hi,

    Nice Video. I think results would be more accurate if the same driver drive different bikes and then comare it with time took to complete particular distance. Again batteries on both bikes are of different types. Another thing is that one girl is concentrating on her cycying only and another is filming as well driving.
