    A few questions from a new Builder...

    So I purchased an older used 2 stroke bike from a guy. First time ever riding one of these things, and sooo much fun 👍😁 Worked pretty good for a while, but now its having some issues. So I decided to try to build one on my own for the first time brand new. Ordered an 80cc PK80 off Amazon. A...

    DIY Wide Crank

    I looked around for just one side of the wide cranksets to clear my pull start, and found 1 result at mbrebel. It was reviewed on this site, on another thread as being made "dirt cheap". The price was 28 dollars plus 8 for shipping and, that was too high for a piece of metal, so I made my own. I...

    Are there any other 66cc/80cc engines out there or better?

    I'm new to the forum and wish to build a motorized bicycle. I plan on building the 66cc one first, but I have bigger ambitions after that. I looked at a Kohler's SH265 and SH255, I am wondering if it is possible to mount these engines. They have more power, and most importantly, have better...

    Best motor out there?

    Out of anything people have mounted on a bike, what would be the best in performance? Whether it be 2 stroke kits, 4 stroke kits, chainsaws, you name it. What would you say is the best for speed/power?

    Motorized bike build #1

    First bike done! I got the kit from a guy in a sketchy warehouse but it seems to run good! I believe the motor is a 66cc and the bike is a 26" Tim Horton's bike I found in the garbage. Everything runs great but My exhaust gasket is bent as far as I know so it spits oil at my boots when I'm...

    Parts jamming break lines

    So I see a lot of projects done on bikes with the break lines going under the top tube. Mine are on the top and when I bolt my fuel tank on, it presses on the cables and screws up my breaks and my gear shifter. Anything I can do?

    My third build : Doing it right

    My previous motorized bicycle builds where poorly thought out and built but due to some circumstances I'm currently facing I've decided to renew my interest into motorized bicycles since I'm 100% positive my car insurance company hates my guts and plans to drop me the moment they can (I was in a...
