Something tells me that we would not qualify for a free sample...

Mr. Zhou, I would be very interested in obtaining a free preview sample of your 16" 5000W - 8000W motor. If such a motor should meet my needs as a hobbyist, I would be more than happy to post reviews on this site and endless-sphere.com. :lol:

Rob, here is the scooter motor you need for your next Pocket Mod project. Maybe a 12" 8000W stuffed in one? :twisted:

Cromotor (aka Hubzilla), rated at 5kW continuous and people run 10kW through them all the time at endless-sphere. http://greyborgusa.com/products-2/motors/hubzillav2/

But it is a $600 motor that requires a monster controller and frame to handle it. Power wheelies and 60+ MPH.

Here is a video of a guy in Costa Rica hitting 103 MPH on his Hubmonster ebike!

Nope, I think he claimed to hit 166 kph, which is 103 mph.

103 kph (just over 60 mph) is commonplace in the ebike scene. With about 20 more volts and 20 - 30 more amps (and a bigger controller to deliver those, of course) I could probably hit 60 mph on my bike for a very short period of time. But 100 mph is a MUCH different story!

Ida Know, 103mph on a ebike with that kind of traffic would be beyond depends and into astronaut diaper stage. Sure didn't look that fast though.

Depending on the price, there could be a nice market for the 4kw - 10kw motor. The market has a ton of cheap 1kw - 2kw motors, but the higher powered BLDC hub motors are not as common, mainly on bikes we see the larger Crystalytes and Cromotors which are in the $600+ range for the motor alone.

My high speed wound cheap 1kw hub motor was just $150 shipped and will reliably take 2kw, and 4kw for short periods of time. But it would be nice to have a motor that could take a continuous 4kw+ with a ton of torque.

Il stick to my pie thank you
70nm of torque talks for itself lol

your 3000w 72v (5131w) only produces 52nm under normal conditions
pie will do 70nm all day for less than 1/3 the wattage
I know where my money will be going

its not all about size
