Default Home made motorized belt drive.. Is it possible with kids bike rim?

I am curious if anybody knows of this. I met a guy that said he did this when he was a child and they used to take childrens 10 speed rims and attach them to spokes and aligned a snow blower motor with the belt and worked fine. .. Or so I am told. I love to weld but prefer logical reasons before bombarding myself with cosmic rays and smoke.

Please post pics if you got em..

I have the EHO35 on my BMP kit and am getting bored with the speed and lack of responce in the rain.

I always wondered how those driving wheels are attached to the bike wheel. Extra spokes?

Reminds me of a commercial about most vitamins being.. "Rocks and shells" ground up. Thanks for the attempt.

I love that Evans bike. I collect Evans' tools. Is that the same company? Well any motor with a belt pulley and tensioner. I have been plucking through these posts and have not found one yet. I did see a contraption on youtube though it lacked pedals. It seems the GEBE kit tops off at 43cc motors or perhaps a 49cc clutch size? I think that the 49's have a larger clutch than the 76mm ones I see on the 35cc motors? Anybody for everybody?

Anyhoo.. The belts I see all over these forums have notches. I have seen water pump pulleys and home made notched stuff most with no pictures leaving me still wondering about slippage.

Thanks for the old HD or Whizzer type looking picture of the Evans.. It is sweet.

Drilling lots of holes, thread lock and or other machine screws twisty wires and maybe even compressing or hammering a rim tighter.. I am pondering this mess and wonder if it's possible.
The snowblower has a gear housing that engages the actual blower part and perhaps that could be used to engage the wheel.

I just thought of this. Some old furnace blowers have a belt drive and a huge cast iron wheel. Perhaps that pulley (wheel) can be used to fix to spokes and would work well. I know ratio's may be off but that could be compensated for on the clutch. I think. This wheel might also be too heavy and hurt/damage spokes.

Another thought I had was cutting a slice out of a very large PVC used for sewage or something as a pulley. If you ever stumble here.. Please post an idea or a picture.. This zombie topic needs to be resurected often... What to do..

Thanks for the links.. I think the Motor Mayhem link is for a chain and the Tanaka link is only sold with a motor. I will end up with a gebe kit unless somebody brainstorms an obvious solution. I really want something like that Titan motor or a 49cc motor and a belt that will take a pounding pulling heavy loads of up to 200 lbs. on a pull behind trailer.

Must make for a quiet running bike using a belt instead of gears. The gear whine on my Grubee 49cc is pretty noticeable.
