Yes I think it may save a bit of money in the long run if you are looking for high end performace to go for a slightly bigger cc scoot.

The halls work a treat
. 60MPH+ easy , just down to bottle
, I have rode these little 50cc scoots in the past just beyond 60+ for normal road use but it all starts to get a bit scary, but with a little nip and tuck of the frame geo they can start to feel very stable again upto around 90
Are you using your 6fet controllers on this?
(I am sooo anticipating my bike with that motor & this thread has been 100% encouragment)
I am totaly impressed with this builds success.
This is the 12fet controller with STANDARD fets but with beefed up tracks and current limited to 70A!!, The controller works well but do get hot so needs to be nursed a little ( I will be rehousing and also some form of forced cooling ) Its the cooling that Im finding is the limiting factor for these controllers ( and this is defo down to the enclosure design ). The 6 fet will have no problems pushing the scoot at 70A all day long if I wanted it to ( it has up rated fets installed + better cooling).
I'm Hopeing that the efficency numbers works out now as this can and will open up a big new area in performance/speed on any type of ev ( I wonder how compact a cvt can be made
I hope your build kicks some butt with the motor/controller combo, its all good stuff and I'm pleased that my bit of playing has given you some encouragement with your venture ( but I think you were already on the case
