The frames of the Cx200 and cx450 appear to be the same in Australia. When compared to cx200 hard tail is US.

Any tips on mounting the motor?

I like you're setup, there's not much you do with the space allotted . See my blue one on cx24v450 low speed and high speed options thread. The small blue one would be mine but I'm certain that the larger dirt bike style one with the huge motor and altrax controller rips, as for how much travel the suspension has????
What is the motor your running in yours and where is your battery pack, in your backpack?
 
I would ad (besides what I've stated in that other thread) That running that 36v 1000 watt currie motor allowed for back brakes to function and then the chain guards I added were kind of cool to but unfortunately after I had gone through countless motor changes till I got where I was at in the picture I posted fricking currie discontinued making the motors and I was for lack of a more appropriate word frocked.
Not much fun trying to get both chains adjusted correctly is it, ad a derailleur to the pedal side and you will solve part of that issue
 
Hey Mike,
You inspired me with yours!
48v my1020 2000w
48v Panasonic 10.5ah is in the frame (Long black tube)

I just changed my rear sprocket, went with a larger to help with gear reduction. Does approx. 45k/ph
