Found this tonight Ananda , some of their motors look interesting.

Thought I'd share...

some interesting looking stuff there :)

I noticed an amusing translation:
High speed crepe motor used in Electric Vehicles:
maybe "pancake motor" :)

Well 4 of these bad boys:

On a small car (165/70R13 tyres radius 28cm)
4 * 140Nm Peak torque = 560 Nm
Peak Force = 560Nm / 0.28m = 2000N
So a 1000kg car would get 2m/s/s = 1/5g accelleration.
Wheel Circumference = 1.75m, 550rpm =~ 60kph.
60kph = 17m/s so about 8.5s 0-60.
acceptable for a small car.

Bigger wheels = slower accel.
More weight = slower.
Quite zippy on an old mini (tiny wheels, low weight)
Glacial on a bigger car.
Planned EV: '63 Cortina using AC and LiFePO4 Battery Pack

This one would be OK for a single motor in a small to medium size car but would need to retain the gearbox as it lacks sufficient torque for acceleration and hill-climb.

The big question for hub motors is the axle / bearing design load capacity and the capacity of mechanical brakes incorporated into the hub design. Then the suspension mods.

I missed any reference on the site to these specs on the hub motor. They would be the first info I would look for. (after torque Image)

If I were selling a hub motor I would state an axle load rating to start with.

Just being realistic. I really like hub motors and feel they like ultra caps will eventually rule.

I looked at the 24kW (60 peak) motor and it is quite unremarkable.
(unless the price was really good). Compared with the 15 year old AC150 technology of 150kW in 40kg. Perhaps some graphs of the performance would help.
If rated speed and power are 5000RPM and 24kW then rated torque is ~45Nm. Yes, gearbox required.
Price could be the winning factor as this unit could work quite well !

Thanks. I'm hoping that if I keep shoving this info in so of it might stick.

Well, caps one day, hub motors now.
250 km's or bust
