that's another thing, cooling.  not sure what you got in mind but..  ac motors can take a bit more abuse than dc motors when it comes to heating.
you stall an ac motor you got a little bit before the magic smoke gets let out of the wires,  dc now, you'll cook it in a few seconds since it's 100 per cent full power 100 percent full duty cycle.  the link above is expensive but has liquid cooling, much better than ambient which usually needs a hefty airflow, ie external fan or really high rpm's, which now need a gearbox, more room / weight.

i spoke with my China contact and was surprised to hear the motor and controller are both liquid cooled

you can't just go changing the voltage of the battery pack from 72 tp 96 to upgrade the bike.  that will end up a disaster, power mapping, what can the motor handle, inrush, so many things.  Adding a few volts, ok maybe but adding 25 percent?   good luck.

It really depends on what the motor and controller as rated for. My particular hardware is rated for a max of 84v.  But until I get the bike I can only speculate on it's performance.  It's possible there won't be any urgent need to upgrade. but waiting patiently for delivery. And since funds are limited it might be next year before I can even consider any part changes.

thanks
I checked out hydrogenappliances.com and it was a bust
I'm looking for around 50 plus hp or about 37 kw.  current motor is about 20 hp.

yeah nice eye candy.  just hope it performs better than my first bike a yamaha as2-c 125cc twin from 1969.
Don't expect it to match my kawa 750, but maybe it will keep up with my kawa 550

Replacing any one of the major drive components (battery, motor, controller) as an end user will cost you almost as much as the whole bike does, and likely the only way to improve performance will be to replace all three.
Lfp batteries are great for longevity, but just don’t have the power density of the typical ncm cells, so I suspect it’s not going to be light. If you’re expecting a feeling of power I don’t think this is going to satisfy.
Having said that, power isn’t everything, you can have a blast on a low power bike getting your lean on that legal speeds. And let’s be honest guys, any bike is better than no bike, even a Harley if you’re into that.

The bike in it's stock form is my proof of concept and basically a rolling chassis.
I fully expect to mod the bike over time,

the battery pack can be resized, space permitting to 96v at 100 ah or larger.
 
The motor is a question mark, trying to get straight answers from alibaba is like a visit to the dentist - slow and painful.
Its supposed a be a qs brand mid motor chain drive rated at 15 kw cont. 30 peak,  probably air cooled.

The controller is a fardriver  NS30  rated at 270 line amps and 660 phase amps. and should be adequate.

 

I assumes is something like this

yes pretty much.  I've read reviews and utube videos on the e-fly bikes and one had the bike equipped with a 8kw hub motor and SLA battery pack.  Pretty sure the 15 kw mod drive chain motor and lfp battery pack with out-perform the e-fly bike.

doing the math it's approx 26 hp or 250 cc apx.    battery is 72 v,  lfp. I avoid li-ion due to bad luck, friends house burned down.  any bike ?  i have 4, 2 85 kawasaki gpz 550/750, and a hd softtail and now my first ev an electric motorcycle.  I went with the largest motor available off alibaba 15 kw cont. 30 peak.  the battery is 100 ah and i figure will be a good starting point.  if i did math correctly 100a x 72v  = 7.2 kw.  controllers are insanely expensive so i expect this controller is probably cheapest available and the 1st to be replaced.   Still regardless of the bikes potential short comings I'm confident it will be fun on the side roads.  According to utube videos the bike will do 0-60 in 6 and has a top speed of 100mph.  Of course we'll see what it can do once it arrives.
