Friday nights again this fall/winter at SCI. This time we're building motorized bikes

[chadsci]

Hey all,

We had so much fun last year building the Radio flyers that I have been looking for a project for the fall/winter. Awhile back I found these guys building Boardtrack racers online. Using EBAY 60-80cc motor kits and building and/or modifying frames to resemble board track motorcycles they build stuff like this.

and this.


Link to motor kits online. http://www.bikeberry.com/gas-engine-kits.html

Those interested in building something cool this Fall/winter join in here. While I will be building a replica board track bike any type of bike is welcome.


Like we did last year the shops tools will be available for use by those building. The welders(Mig and Tig), grinders, torches, shear and metal shrinker/stretcher and this year the 8 foot leBlond lathe and bridgeport for those tricky parts.

Let me know if you want in.

That looks badass. I may be in, if the wife lets me :-)

These things can be built for as cheap as $200-300. I plan on using a brigs vanguard motor if I can find one cheap enough.
On craigslist there are all kinds of vintage frames or vintage style bikes for cheap.

Not sure if I will build one of these, but I will be hanging out as much as possbile! I still have a few small things to perfect on the wagon yet...

I'm down for hanging out and spectating

[hapsbang]

wish I could fit this into my schedule

[I luv Box]

So what all would we need in terms of supplies? Bike and motor kit?

[igotacaddy]

I have a 2 cycle weedeater motor. If someone is on a tighter budget, It could be had for the low low price of Free.

I should be down a few different times

I think I'll participate as well. I'll probably work on it mostly up here in Saint Cloud and go down there every so often and fabricate and hang out with you guys. This is just the project to get me back into top welding and fabricating form.

I've been thinking of making a gasbike for a while...

Gasbike.net has some neato kits, or just parts if you want to piece together your own setup.

This sounds like fun to me!
So do these get classified as mopeds if you stay under 50cc? I'm not sure how the law works when you put a motor on something that didn't have it before.

I've done some exploring but I keep finding contradictions. I found one this that said motorized bicycles under 50cc and under 30mph don't need registration and I've found ones that said they do. So what happens if I want an 80cc do I have to get motorcycle registration and put lights on it?

Tell the cop that pulls you over its a motorized bike and its a modded 49cc... like he is going to be able to tell its 80cc. And there is nothing illegal about modded 50cc's
