This is video describes how a BionX motor works.

- brushless and gearless motor
- 85 - 90% efficiency
- no internal movement parts
- internal sensor
- pedal proportion assistance

That setup wouldn't have a lot of moving power... You would have to pedal to get it to start moving... It works great when the wheel is free to spin like in the video, but put it on the ground and it's a different story.

This works just like a computer fan. They can spin fast, but you can easily stop them. And if you hold a computer fan they don't try very hard to get them selves spinning.

@mattg889

do you own one before? I rest my case.

[mattg889]

@powerinmotion Your right, I have not, I am not that wealthy. These are a great design/idea, but I'm skeptical of just how good they are. So since your the all knowing one... I know these use the same principle as a computer fan motor, and for a computer fan to have a lot of torque it would use a lot of amps. So tell me, how long will one of these things assist you at FULL load before draining the batteries?

I don't mean to be an ebike snob. And I don't look down on people. Yes, Bionx is expensive, but it is one that stay out from the rest when it come to technical advance. And we would be very happy to answer your question. You will not able to hold this motor by hand, either you will flip to floor, or you will have your hand broken. A computer fan had not torque, the only purpose is speed to move air. This motor had both speed and torque.

The battery is 37v 9.6Ah. Which translate to 1.5 hour riding time at 32km/h without pedalling.

oh, it changes porarity.. i see

That's one amazing motor, but I guess to be 3 x stronger than me at my strongest, you'll need about 2kw

Got my Bionx and I love it. It's intuitive and makes bike riding a blast. My only complaint is that I'm a big guy, and at full power going up decent hills the battery drains quite quickly. In otherwords, I wish it had more range. A second battery is out of the question for me, as they are $1,200!

@gotrottin

Good for you!

Hi...

is there any chance, that BionX will have sometimes also plunge-mount for the pinions ? (i don´t know how you call this in English)..

i mean the kassetts

in the moment you can only use screwed-on pinions which is technologie from yesterday.

it seems not to be a unimpossible thing, there is already a motor which uses kassetts for years (but needs more than 135mm at rear width)

and now there is also one that fits into 135mm

when will BionX switch ?

@mattg889 You can't get assistance above 20mph; anything above that and it's like it's not there at all. It's best thought of as a tool to assist you in tough conditions (uphill or into the wind, where you'd struggle to hit 10mph normally), rather than a continuous use item. That is, unless you don't mind averaging 15mph or less. The more expensive models have a variable throttle.

Congratulations, you are paving the future of transportation.

[mattg889]

@powerinmotion Now that I like to see, numbers. About 20mph, not to bad, makes me wish I could afford one. What would be an average persons max speed with the motor with pedaling? (20 is a little slow for me) :-) Another question, can you switch between a couple modes? Because in videos I have watched, I thought it only assists you while your pedaling.
