Design update..Looks like rear suspension is doable, which im super!! happy with / has to be comfy-ere
-- ill have to take a hit on main frame size but should still be able to get 20ah of 60v, plus a controller and stagger the air shock on one of the swingarms arms.
The deck will be wide enough to stand both feet parallel facing forward [ cruising ] and ill have a kick plate at around 45 deg at the rear, so i can have one foot forward and other on the rear kick plate which will be a good solid stance for hard acceleration ect also covering the rear wheel like a mudguard .
Ive been struggling finding 30mm belt torque nm ratings, so i spoke to my local harley shop and they use 25mm on one of there nearly 2lt bikes
So thats good enough for me as my power should be around 8/10kw ... 30mm belt it is .will go over design this weekend and hope to start on main frame next week.
