Is it posssible to mount a 5303 hub motor in a 12" spoked Dirt Bike wheel. I am thinking of mounting it on a scooter/moped style e-bike. It currently has a 12" wheel with a hub motor but I think the crystalite 5303 motor is more powerful than the stock motor currently installed in the bike. The stock motor is said to be a 600w motor and I am currently running it at 72v with a top speed of 30mph. I use a 72v 45amp ecrazyman controller. I am not sure how many watts it would be running at right now. I don't have any test equipment to figure that out. If anyone has a guess that would be good. It also has drum brakes attached to the hub motor so I am not sure how I will stop the 5303 if I do install it. Any ideas on that as well would be great.
Crystalite 5303 motor?

Well a "16 inch" motorcycle tire fits a "20 inch" bicycle rim so I'm thinking the x5 is way too big for a 12 inch motorcycle rim.

I don't follow you. How can a 16" tire fit a 20" rim The 5303 is 254mm tall. Which is 10". Could you actually mount a 10" hub motor in a 12" spoked wheel. Spokes would be really small I guess.
Can you mount a tire to the actual hub instead of putting it in a rim?

My 5304 has a diameter of about 10 1/4,, mabye 10 3/8". If the inner diameter on the rim was 12" you'd have 1 1/2 inch spokes. Pretty tough to lace I bet.
To put a tire right on the hub would be difficult, where would the valve stem come out? But mabye you could machine some rings to bolt to the hub, and then mount the tire right on that, with a hole in one ring for a bent valve stem.

It might be possible to use the no-air, foam type of tires but with either these or pneumatics there's still a problem. Hitting a pothole or curb hard enough would bend a rim, bit if there's no rim it'd damage the motor itselfdogman said:

Was only comparing to get an idea of how large a 12" motorcycle rim is. Most of the experience with these hub motors is on bicycle rims obviously. The two naming systems for rim size are different. I don't think mounting the tire directly on to the hub is going to work. Methinks the way to go is to find another 12" non-spoked hubby wheel that is more powerful..

Bicycle tire sizing is goofy and generally reflects the approximate diameter of the tire and not the wheel. A 20" bike wheel can be as small as 406mm from bead to bead or 16".

It is goofy. My scooter style ebike has tires that say 16"x3"' on the tire even though it mounts to a 12" wheel. The funny thing is the overall diamater is 17 1/4 inches from top of tire to the ground. It just makes nosense. I talked to kenny at crystalyte today by email and they have a 10" wheel with the 5303 mounted in it. My worry is won't a smaller 10" diameter wheel require more watts to acheive the same top speed I am getting with a 12" wheel? If so it might not be any faster top speed wise with the better 5303 hub motor on a 10" wheel. I like the idea of machining disks to mount the tire with a hole for the valve stem.
Finding a faster hub motor on a 12" wheel is difficult. I have searched and found nothing. Could anyone lace a wheel with 1 1/2 spokes?

Did you see the kelly hub motors they have a 13 inch version and they have the tires for sales too i wonder if it would work with your setup ...http://www.kellycontroller.com/shop/?mod=product&cat_id=51,16&product_id=474
