    Hey, i've been lurking around this site for a few days i i just thought i'd check in:grin:
    My friend and I are contemplating building some motorized bicycles.
    I'm not going to buy a kit, because i don't really want to spend any money on this.
    I've got a few bikes (banana seat bmx style, huffy kid's banana seat bike, mountain bike, and a foldable bike)
    I'm probably going to use the foldable bike or the bmx (or a combo of both).

    I'd like to build a set up so i can utilize multiple gears for the engine, and have maybe one gear for pedaling. Has anyone else done this?
    I'm looking into my options for an engine and a weed whacker seems to be the way to go. But, i'm wondering if i could use a push mower's engine instead?
    I know those engines have a vertical drive shaft, and normally operate on end, but could it be modified to run the other way?
    -thanks

    Hi, Do a search on building from scratch, on multiple gears, and weedwacker drives. Then ask if you can't find.

    Welcome to the group!

    Yes the vertical shaft engine could be used. You have to use a belt and make a jack shaft with a verticle pully. Just twist the belt like on an edger. http://www.smallenginewarehouse.com...riggs+Lawn+Edger+4+position+height+adjustment

    Welcome to MBc. A few have tried the multiple gear setup (including me). I decided it was more work than I was interested in putting into it. Perhaps you will come up with a breakthrough. For low cost, you might look at:

    Keep in mind that these guys have built a few.
