In keeping with my addiction to put a motor on anything with 2 wheels is a plan to motorize my pedal only bike with a small FD. I wanted a 4stroke. There are many out there but most are designed to run a centrifugal clutch and mount to a heavy bracket. Not a bad thing but my target is to add a unit weighing 10lbs or less as it will be on the front. Also have in mind to make it quickly removable for use in restricted areas/bike paths. Idea is to pedal the bike most of the time and use the FD when I'm pedaled out. The victim in this build is a composite bike built from parts left over from other builds or scrounged off the side of the road. The basis of the drive centers around an Echo curved shaft head. It uses ball bearings instead of bushings like a lot of trimmers. The engine is a Briggs Fource 34cc Flattie oil in sump engine. This engine got a lot of use in R/C aircraft conversions, where it had a good reputation/reliability. Not a real power house but has enough for what I'm wanting. Initial drive roller is a Lawnboy 7/8 LH roller. 7/8 is small for a roller, but I'm not after speed. Should run easily 10/15mph. Engine should be here Thursday. Pics are of all I have so far.
