This bicycle has a Unite MY1018Z 450W 24V motor attached to the cranks. The motor has a 7.18:1 gear reduction built into the motor itself, and there is an addtional 4:1 reduction from the motor to the cranks. I have a special freewheeling crank system that allows the motor to turn the chain and the pedals to remain stationary. I also have a Megarange freewheeling sprocket in which the smallest gear has 14 teeth, and the largest is 34 teeth. This gearing allows for a maximum speed of 28mph. Normal cruising is around 20 mph with no hills or wind. The beauty of this system is that I can use my bicycle's six gears to match road conditions. The motor sprocket has a freewheel so that if I pedal without the motor, there is no drag caused by the motor itself.

Nice job on building your bike. I built my bike using a Chinese built 1000w brushless motor in the front hub. I also use Lipo ( 6 to 8 5000 mah 6 cell). The system works well except it came with a cheap rim, which could not take much pounding and after traveling over 1200 miles it was pretty much bent out of shape which ruined a tire. Switched to an older solid steel rim it is a little heavier, but more durable. Keep up the good work.

Only the average KZfaq idiot would not see the pedals on the bike and make ignorant, negative comments about you getting stranded. The batteries died? YOU PEDAL THE FREAKING BIKE. What's so hard to figure out here? I think you did a great job putting this together. Neat, clean, and functional. If the motor is DC, is there a way you could reverse the wires with a switch and use it to pedal and charge the batteries? Most DC motors will produce current when they're spun backwards.

Super set up. I have the MY1016Z2 with 9.78 reduction. Trying to figure out a similar set up with round tube frame. Found some perfect fitting U-bolts and bed frames from the dump supply fairly decent angle iron. Lithium polymer batteries are great. Maybe I can use the same ones I use for my RC plane (3000 Mah) for a start. Planning to run the chain directly to one of the 3 front gears already on the bike since I probably won't need all 21 gears once the motor is doing part of the work.

From my understanding, which is very limited, it takes 4x the amount of energy to go twice as fast and wind resistance goes up exponentially with speed very rapidly. It might also be worth your while and provide a lot of information to potential adopters to do varying tests, 10mph, 15mph, etc. I think I misspoke about 1/2 the wind resistance, it would probably be substantially less at 10MPH than at 20MPH. Thanks.

Put a cotton ball on the mic on the camera it cuts the wind noises. You could passively charge up your bike by adding an extra wire and a large diode to the motor feed wire to back feed into the battery when you peddle the bike. This way it bypasses the controller and you can recharge passively without sending power into the motor directly.

Hey Hutch, Great bike! I am designing a similar bike and was considering putting the electric drive sprocket on the other crank so that it makes the build much simpler.

Is 450W decent enough?

Hey hutch transfer, I don't know if this was mentioned but have you considered adding a peddle generator or even a friction generator to give a little bit of a charge back to the battery while riding? and thanks for explaining every great vid

@hutchtransfer 8 жыл бұрын

+Josh Wail It takes a lot of energy to charge the batteries. The amount of resistance created during charging would make the bike harder to pedal and the energy you get in return is negligible. If you are in decent shape you can produce around 80 watts of energy by pedaling, so it would take about 5 to 10 times longer to recover the energy you are getting out than it was to spend it. Regenerative braking, however, does charge the battery but it only extends your range by about 10%.

If you put a 1500W motor onto the chain rings/bb, you'd probably rip the chain rings apart. It might also crack your seat tube or down tube, wherever you happen to try mounting it. You could also end up just breaking the bike's chain or ripping the back rim out of the slots. Don't laugh, it happens to the hub motors all the time.

My motor is 450W and it the top speed is around 20mph on the flat. Uphills in the slowest gear it will do about 5mph. Normal cruising is around 17mph. If you want higher speeds then you will need to get a more powerful motor.

@nikpapan 10 жыл бұрын

***** Thanks for the answer! Well my question is whether the amount of Watt is enough to tell you what a motor can do, or whether there are more parameters one has to consider . Kind of a physics question.

@hutchtransfer 10 жыл бұрын

Watts will give you a good starting point as to the power of the motor. However if you have any sort of gearing on the motor then the power will increase. My system uses the bicycle's gears, so even a 450W motor can propel me up a 10% grade, however only at 5 mph. To go up a hill at faster speeds would require a more powerful motor.

The Bafang would mash up a front derailleur in the hands of a novice. Before I got a shift sensor, I was changing gear using one of the brakes to cut the motor. I've climbed 20% gradients in the 52 tooth chainring BBS02B with a 32-12 cassette, but I did have to pedal hard to help the motor out. It did actually climb without it but it was under a lot of load (the bike did about 9 mph instead of 14-15 with pedaling). I think if you can put a 48 tooth on there with a 40-11 cassette you will have enough range for everything and can always drop to a 32 tooth for steep climbs if you don't care about going 40+.

Even with a less efficient motor, I should think that this setup is orders of magnitude more efficient. I think the hub motor people say 20mpc with peddle assist, are you getting that with no peddling? Also what is the total cost of this setup - battery pack and bicycle? How much do you weigh? How much is a battery pack going to cost? Thanks, I'd appreciate it.

@hutchtransfer 9 жыл бұрын

Ashwin Ramdas The only time I have had the motor overheat was if I was doing continuous climbing on steeper grades with no pedaling. Putting that much strain on the motor is not good and will cause it to overheat. Therefore I always pedal with the motor in that case. For normal riding on the flats I have had no problems of overheating. In order to make more cooling, I have drilled holes in the outer back case for ventilation. I have seen people do that on endless sphere. I have not had any problems
