How can i mount a chain to a ryobi weed eater engine?

Question

Its a model 765r, and i am trying to mount it on a bike. I need a way to mount something to spin the chain on the engine's internal spindle.

Answer 1

endless possibilities. however its really up to you, because it would be impossible to tell you how to do it without being there in person. you've got to find a sprocket that will fit on the engine and also fits the chain... maybe at a lawnmower shop? you can bolt the engine or weld it if you have to tools. dont duct tape unless you're an idiot.

Answer 2

you duck tap it on the bike

Answer 3

You can mount one, but:

before doing this do some math on engine speed verses wheel  speed.

A normal small gas engine is spinning way too fast in rpm's for what is needed for bike wheel rpm.  slow the engine down and you don't have enough torque/power.

so you need to have some significant speed reduction, as your bike wheel wants about 100-300rpm  and your motor is going 2000 -5000 rpm.

added advantage is as you gear speed down you multiply torque/power which is what you want  for hills.

Do your own math based ou your wheel size etc.

that is the usual challenge; consider a dual gear reduction system as it is hard to get a 10 to 1 speed reduction in one stage.
