Belt to chain or Belt to Wheel Drive System

[Thaxos]

Hey, I'm new here and I have tried searching but nothing yet, so I'm turning to you guys to help.
I have one of those carny games e-scooters that I've disassembled to get at the series wired SLA batteries, 12V each at 4.5A and the MY68 DC Motor 24V 6A 100W.

Trying to figure out a way to make it work with a bike in terms of belt drive to the wheel. Searching the forums but there isn't really any post explaining where to get this 'GEBE' everyone talks about or a simple way of converting belt to chain. Friction (?) or direct contact with the wheel is not a good idea here since it rains/snows often and I want no slipping of the motor on the wheel.
I'm a fit guy, 17 yrs old and about 110lbs, I'm on the slim side of things but all in all, I don't mind pedaling but I have asthma and gas prices are ridiculous. I love biking and would really like a way to help me get longer distances so a bike ride to the University for next year wouldn't be so tiring.

First GEBE is Golden Eagle Bike Engines if you look to the colum of ads to the left of this page you will find a direct link to their web site. Their set-up is a rack-mount system and would require quite a bit of modification to adapt it to a frame-mount electric. Whizzers also use a V-belt drivetrain and could be a source of parts for what you describe, http://www.whizzerusa.com The following is a link to a thread showing a project of mine that uses the Honda GXH50 motor and Metric Timming Belts and pulleys for the drive train http://www.motoredbikes.com/showthread.php?t=7580&highlight=belt+drive&page=3 One more link to a belt driv project using v-belts and pulleys by member of this forum http://www.motoredbikes.com/showthread.php?t=11180

Thanks for the reply, however I am talking about an electric bike, not a gas powered one.
I was hoping for a less inexpensive way to do this without having to go out and buy a whole kit but unless someone has an easier idea, I think I'll end up getting a hub motor kit.

Does the bike have disc brakes or V brakes? Chain drive is pretty easy to do, but a 100W motor is not going to get you anywhere fast...

 

[Thaxos]

It has the brake pads that press against the rims.
What could this motor handle then?

 

[heathyoung]

Depends on the physical size of the motor, but you could over-volt (ie. put another battery in series) to get a bit more power out of it.

The reason why I asked about the brakes was that you can use a disc hub and bolt a pulley to that - it will be strong and nicely centred.

Ahh, it's fairly small, it's from an e-scooter
