What will you use to actuate the caliper? Hydraulic or cable?
Jay64 said:If you are making it for a rear wheel, then I would suggest keeping the foot pedal. If you are making it for a front wheel, that brings up another question. A lot of bikes are coming out with "upsidedown" forks. Those are usually on the bigger bikes, but even some of the dirtbikes are coming out with the "upsidedown" forks. If that is the case what would you be attaching the torque arm to?

The weight of a hub motor will be a minus for suspension performance, but the quietness and space for batteries will be nice.

Man, that is *spiff*!
I need to get the Lead Sled done and then own up to all my mistakes. Then I can think about getting some kind of 350-500cc class bike and putting something together with this. Good idea, BTW, to keep the rear brake on a pedal. Us hardcore motorcycle types will tend to put our heads in "motorcycle" setting instead of "bicycle" in a tight spot. I know I'd be stomping my right foot if my brain thought I was on a motorcycle. (Let's set aside the fact that I learned on a motorcycle that only had a rear brake, a foot clutch, and hand shift. Try to stop on a steep uphill... )
I'm gonna guess I just found another summer project. *sigh* I need a longer summer.

Trying to guess voltage required for speed.
drewjet said:From my memory, and I am certainly no expert on this...If you double the width of the stator the KV is 1/2
michaelplogue said:Good to see progress on this. However, I've got two concerns:
1st - I see that your prototype is using a standard bicycle disc on the left side of the wheel (understandable since your test-bike is modeled to use a bicycle hub motor). Motorcycles use a heavier disc on the right side. What will the final config be?
2nd - Because a motorcycle has much more mass than a bicycle, a lot more force is needed to stop it, and more force it put onto the disc. I'm assuming that the discs are being mounted to the motor cover. Is the cover of sufficient strength to handle these forces?
