Motor Choices For Electric Motorbikes

Post by gttool »

Decided to convert my Husaberg to electric power I have looked at all the choices for the drive but really what do i need to use to get similar performance ??
This bike does produce over 50hp so I might be asking a bit much !

have considered the perm 132 sepex or do i just go ac?

would be running 82v lithium cells
approx 200kg including rider

what performance should i expect?

Thanks Geoff

Gday geoff,

to get 50hp out of thundersky you will need 144v90AH 150kg.
youll get loads of range (130km+)...but for a sports bike, heavy.

50hp out of K2 cells welded together you need 144v 25AH, 45kg.
range not so great (45km), but power and weight are ok.

the upside to having a bike, batteries are of the size where a "fast charge" is actually feasible.
a 415v 30A connection would get you 20 mins from SOC 5 to SOC 95.

as far as motors go,
for 50hp, youd have to use DC series wound, AC at the moment isnt up to the task for 50hp in "bike size".

an L-91 with a 144v 500A controller would do the trick.

you might find that 82v wont give you much in the way of performance at speed, even if the pack is capable of the 50kw needed to get 50hp at the wheel.

So the short answer is NO but the long answer is YES.
