    Built this from a wal-mart bike and a Grubee 66cc kit. The kit was very complete BTW. I made a custom front engine mount with solid rubber bushings. It really cuts down on vibration.

    It looks good! Alot like a blue version of my Atlas build in the works right now.

    Ended up ditching the front fender after reading some horror stories and adding a front brake. I upgraded the coaster break torque arm as well. It is made from much better steel. It was nearly impossible for me to bend it to the proper offset. The original one got all mangled.

    Is it safe to run a rear fender?

    Nice bike! How about a close up of the motor mount?

    More pictures of the ghetto fabulous motor mount and chain tensioner.

    Tension can be adjusted by changing the spring and/or moving the mounting point (see the three small holes). I think this one is around 25#.
    One thing I noticed while riding is that when I popped the clutch the tensioner gave way slightly, but not enough to derail the chain. I'm thinking this may help lengthen the life of my rag joint sprocket.

    Now I can compress the tensioner to ease removal of the rear wheel.

    No clearance issues.

    I think I'm going to take a few pages out of your book for my own beach cruiser! Hooray for trix


    Actually my biggest thing when building a motored cruiser was that coaster brake. I did not want one at all. I have never had good experiences with them on terrain that's not perfectly flat, and the term 'high quality coaster hub' is an oxymoron. This is to sayy nothing of the horror stories out there from motored and non-motored cyclists.
    Now, to my knowledge there's no actually -good- way of converting coaster to freewheel without replacing the hub outright. Long story short the rear wheel was pretty much the hardest thing for me to find what I wanted.

    Having mused on the coaster brake, I'd like to comment on your chain idler.

    Very nice. I might have to inaccurately reproduce that design because the stock idler on my bike is going to get me killed some day.
