Re: Minimalist FD
Got and modified the BMX peg. If I still had my lathe I would have turned a bit off the nutted end. As it is its a perfect fit to the area of the tires contact. I trimmed off about 2.5 and retapped to 3/8 24. The is peg actually 1.32"
I havent ridden it out on the paved road but it worked fine on our sand/gravel island road. It is the max size for the 21cc. Have to help it to about 10mph then it begins to develop power and slowly accelerate. Will do much better on pavement.
So this is an easy cheap way to get a minimalist lightweight MB. Makes for a neat little bike you can throw in the car, ride bike trails(engine off or quickly removed) with almost no additional weight. I came in way below my 10lb limit. It requires minimal fabrication, less than an hour. Was thinking about a total bolt on/ together method, but that may very with the brand of trimmer.
The newer 26cc trimmers make good power and cost around $79. This method will work with any bike with the common non suspension fork. So if one has a bike laying around a motorized bicycle could be constructed for a $100 or so using a new trimmer. If you yard sale it 1/3 to 1/2 of that. Just don't use a trimmer with a bushing head, also it must be a curved shaft not a straight shaft trimmer.
