    Two speed concept.

    The Two Speed friction drive. I started with an idea to tackle the hills that surrounded where I live. I didn't want to sacrifice good cruising speeds for sub par torqued out low speed climbing, so I built this, with the help of a local machine shop. The lever that brings it back to (D)...

    Almost giving up on my first 4-stroke build

    So last summer I saw a video about a motorized bike build on YouTube. Seemed simple enough. Just slap that old 4-stroke on there and bam, cheap motorcycle. I found my dad's old trash mountain bike and bought the standard Huasheng 4-stoke all in one kit on Ebay. After putting everything...

    New to motorised bikes (Hello! & little help)

    So at the time of purchasing the 2 stroke kit for my bike I really didn't know what I was getting myself into until spending the last 2 weeks putting it together and dealing with one issue after another. I realised there is a lot for me to learn and I should have hopped on to the forums before...

    Seeking purchasing advice.

    I'm looking for what is effectively a "Car replacement" motorized bike. I have an E-bike that I built but my batteries died in storage from the winter cold (oops) and I don't want to spend a grand on new batteries. I plan on using the electric motor for a recumbent trike in the future anyway so...

    Why motorized bikes?

    Just a question. Why do you ride a motorized bike? Why, if you do, prefer motorized bikes over another vehicle? Just looking for some opinions here. Some of my reasons: -Fun and easy to build, especially if you can't afford a motorcycle -No registration required in most places -Good way to...

    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...

    Chainsaw bikes

    I got a guy who wants a motor on his bike and I mentioned motorized bike kits. But then he found videos of bikes with chainsaw motors on their bikes. Is a 2-stroke kit better than a chainsaw bike? I understand that a chainsaw would take more work, but in the end, which out preforms the other...

    1. Shipping was pretty fast I ordered the engine on May 24 for 169 dollars with free shipping. I got it on Wednesday May 31. It's estimated arrival was June 1 so it got here early. None of the parts were missing, it does smell like it's been used. It did not come with an instructions manual.

    Unboxing the Roadmaster GranitePeak

    I originally brought this bike already assembled by Wal-Mart for 78 dollars plus tax. Within the first 24 hours, the bike wouldn't shift down into first gear. One the second day the handle bars slipped. I read reviews about it being a good bike so I returned it and decided to assemble it myself.

    Playing with ideas

    I've playing around with some ideas in my head about putting an electric motor powering the front wheel. I know there's kits but that's too easy and too $$$. First it helps to see the motor that piqued my brain. Here it is. Now that you've seen it here was...

    Can I swap a predator 79cc engine with an engine that comes in the kits online?

    Hi, I am looking to put an engine in my bike. Is there a way I can use a predator 79cc engine instead of the ones that come in the online kits? I know that the engines in those kits arent of the best quality. Or is there a kit online that is just all the parts and no engine. I dont want to have...
