Hi name is Ron, I'm in B.C. Canada.
I am new to the form but not new to motorized bikes. I have built about 6 or so over a couple years. My current ride is a full suspension total custom purpose built frame. With all downhill equipment, triple crown forks, etc. dirt bike body.
I run the final drive through the bicycle derailleur system, I have 9 gears to shift through.I drive it hard like a dirt bike, you don't pedal to start off, it will lift the front wheel off the ground.
Here is a link to a pic of it.
I have lots of knowledge from trial and error over the years so if you have any questions just ask. I have used all the hubs out there including a new Nuvinci N360, Which I blew apart in 3 days, there goes $400. O'well R and D sucks sometimes.
Like I said just ask, if I can help I will.
