I am not clear on what specs you are running... I am researching electric bike parts, I like this motor and might use it, can you answer a few questions?

-What brand battery? Type? -Series cells and how many parallel?

-What controller?

-At 48volts, the motor is capable of 7hp, how do you not have enough power at 75volts, should be a rocket... are you using low quality battery cells?

Thanks.

@Zeropointbug

Sony 26650VT Cells. Rated as 3.2 AH and 20C. I have 18 in series and 12 Parallel.

It is a Kelly Brushless 72 volt 200 amp controller

I have enough power. I now have over 6000 miles on it and the cells are starting to loose capacity. I use it as my daily commuter to work 8.5 miles. I run it at about 45 MPh and am quite happy with it. If the cells get to the point that I can't make it to work I will replace with Lipo from Hobby King

too much motor for a bike :)

my dc etek wastes a lot of energy running idle which is terrible. how much does that one use to just spin?

for instance to maintain 3000rpm with no load. and how well does it keep spinning if you just spin it by hand?

@DanFrederiksen

I don't recall the exact amps but seams like around 4 amps at full throttle

Lead acid or lithium ion batterys?

Lithium sony cells 18S12P

I'm going to make my own brushless, my first magnet have arrived at my place, it can lift 60 kilograms and hopefully repell just as much.

It's gonna be mounted on the inside of the wheel and the wheel should be hubless.

Going to order 3 more of these ;)

No batteries will be needed as the magnets create its own electricity due to the reaction created by its magnetic field.

I need parts and the tools, then i'm ready to head in to the future with my own hands =P.

It's gonna be a blast ^^

since these are losing their capacity, have you looked at a123 cells? They are supposed to have a longer life cycle.

wow that things quiet.

[mikedrazen]

very cool, nice e bike, really

[circuitdotlt]

OMG, batteries losing their capacity after only ~100 cycles (I guess ~60 miles per charge)? Thats a failure...

How do you have the Phase and Hall sensors wired from the motor to the controller? I have a kelly controller and brushless etek.

Mine is:Hall Control to Motor A=W, B=V, C=U. Phase to motor A=B,B=G,C=W.

Also, does the video show FULL acceleration?
