hey, im new here and was hoping for some good advice, i have 2 bicycles, 1 20" normal and 1 26" mountain bike, and was wondering if thers anyway to set up a engine, for under $150 us for either of them, and also what kinda speeds i can expect if done
Mounting weed eater motors is cake. On all of mine I have there is 4 holes where the plastic casing bolts to usually. i drill the bottom ones out and weld 2 mounts to the frame to hole it in place, and one on top for support so it wont bend the mounts and the shaft is straight. Ive seen people use springs but I just use solid mounts. But when getting the mounts in position, I keep the tire pressure low and the axle in the middle of the frame mounts so I can adjust the pressure. For the shaft I used a 14mm deep socket It works, and I just welded it to the old flex shaft bolt.
Its based on things that are easy to find. Trust me there are no rules to building bikes from alternate engines. Most anything will work. Just get yourself an engine and ASK LOTS OF QUESTIONS.
People here are glad to help.
If you have the bike you can buy a brand new bolens weed whacker at Lowes for 75bucks tax included, That and twenty five dollars worth of hardware and you are rocking. In this section there are several different was to mount your engine.
You need a hacksaw, drill, screw drivers and wrenches.... I use a gavanized water pipe and end cap as a drive wheel. I'm working on different coverings for it now.
Speeds depend more on your topography than anything else. On the flat I get about twenty mpg and I'm 210.. The hills kill you with this kind of engine.
