BMC 600W electric human hybrid bike motor comparisons

Comparison of the new 600W BMC electric bike motors The “torque” versus the “speed” for climbing a steep hill Tested on Xtracycle equipped bikes head to head At 36 volts, 48 volts, and 72 volts
Video Rating: 4 / 5

www.electric-bike-kit.com These amazing Clean Republic motors achieve incredible RPMs for acceleration and power inside a super compact case using a very clever dual internal rotor design.

  1. 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).

  2. 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)

  3. 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

  4. 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 ?

  5. 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.

  6. 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.

  7. 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.

  8. wow good job……..!!!! very honestly… I dont know jack shit bout electronics but I can very clearly make out that u are doin your best to save the earth from the gas guzzling monsters we drive and ride around(although I love them)…….keeep up the good work….cheers!

  9. On the flats it would be no contest, at least at lower voltages. For example, at 36 volts, the “speed” motor tops out at almost 30 mph, whereas the “torque” tops out at close to 20 mph (due to higher back emf, from more internal windings). The “torque” would race ahead for a few seconds, up to about 12-14 miles per hour, then it would get left in the dust as its back-emf kicked in.

    Now, at 72V, this might be a different story. The back-emf on the “torque” wouldn’t kick in until 35 mph+.

  10. which company patents the placing of an elko …… omg creativity whatz that companys like that make me sick because there the reason that we dont have free energy already

  11. im wondering if it is posible to use the wheel on the back as generator to charge a capacitor that i can setup between batery and rest of the bike that could drasticaly increas the range

  12. NEAREST POSSIBLE FRIDAY BY THE LOVE OF YOUR LIFE. TOMMOROW WILL BE THE BEST DAY OF YOUR LIFE. HOWEVER IF YOU DO NOT POST THIS COMMENT TO AT LEAST 3 VIDEOS YOU WILL DIE WITHIN 2 DAYS. NOW UV STARTED READING THIS SO DUNT STOP. THIS IS SO SCARY PUT THIS ON AT LEAST 5 VIDEOS IN 143 MINUTES WHEN UR DONE PRESS F6 AND UR LOVERS NAME WILL APPEAR ON THE SCREEN IN BIG LETTERS THIS IS SO SCARY CAUSE IT ACTUALY WORK

  14. thats cool you’ll get a higher power to weight ratio but its gunna be noisy, maybe less efficient, and don’t try to over power it much the coils are smaller.

  15. Free energy can change the world!But Millions are spend in supressing that information,Get the blueprints for a free energy motor at LT-MAGNET-MOTORdotCOM ,Big change is comming soon!

  16. great work… how many watts this motor is … my motor is 250w and i am wondering how fast it could go… cuz i havent tested it yet… any ideas guys… ????

  17. sorry but i would rater have a motor for yasa 37 cm x 7 cm 500 newton meter of torque
    replace the two wheel of a bike and you got 1000 newton-meter of torque
    around 800 pound feed of torque.hahaha!

  18. @IcechickenSr The regen should work, I think, as long as the gear ratio is not too extreme, I’d say no more than 6:1. I am personally curious about that, too, and it would be good to know.

  19. Nice. I am thinking hard on which kit I get for my bike. I like the gear reduction to reduce motor speed among other benefts, however the largest drawback I’m finding with planetary drive hubs os that they can not use regenerative breaking (please correct me if i’m wrong) I think the regen breaking is an extremely nice feature to have and could really help out with distance. Cheers, IC.

  20. @Leiflton i think im going to get a cyclone 1200w kit and install it on my bike, then you could carry out experiments from there…you could attach a sprocket to the alternator and put it on the chain…you could have one of those friction ones being driven by the wheel, a hub one i dont think is a good idea because of the resistance, would slow you down even if you’re coasting. you want to keep those bearings ROLLIN.
