| |  Rear Mount an In-Frame Engine
Ok, hey I am a complete newbie at motor bicycles but I need some expert advice....
I was wondering if I would be able to rear mount an in-frame 'ebay' kit. The kind that comes with everything you need for like $150. I found some flat mounting kits that are meant for putting the ebay engine in a chopper bicycle. I have added the pictures.
My question, though, is about the logistics, such as: the fuel tank and carburetor system, and the maximum angle the engine can run a chain DOWN (not back to) the sprocket?
thanks |

I think you could probably run the engine upside down!! (just as long as the carb is right side up & level)  |

Looking at the pic... the air flow to cool it, might not be as good back there? |

Wow, that is exactly what I was talking about.
I don't know how to weld...
I am just looking for the cheapest way to get started, it seems like fun...  |

The bike rack would need to be pretty substantial. You don't want the engine moving around......................

With my recent adventure with hot mufflers, the muffler where it is would scare the Bjesus out of me. I would think the cheapest way would be to just mount it as normal. |

Jemma xx | Good idea, I did think of that but I was unsure if it would work.
I need a good way to make a custom rack, or possibly learn to weld.... | | Thread Tools | | | | Display Modes |  Linear Mode |
