how do i make a chainsaw bike?

Question

I know you just mount the motor and run a chain to the rear sprocket, but won't it make me go backwords. seeing as when you use a chainsaw the chain runs from top to bottom shooting sawdust downward. so i i mount i facing the rear wheel i would go backwards right. so how do i keep rear wheel drive and go forward.

Answer 1

so turn the motor the other way...

Answer 2

Two things first change your front sprocket into a pulley and to the chainsaw motor which already has a centrufugal clutch attach a pulley to drive the pulley where the sprocket use to be. To set up the motor doit between the wheel and the sprocket, make sure you weld a plate to cover your bum and your legs so you wont get hit by the belt if it slips. I would give you a diagram but if you are mechanicaly inclined you will figure out the idea anyways. You need at least 3 pulleys. The chainsaw motor if is 32cc or above should have enough horsepower to propelle your bicycle, cant tell you how fast because it will all depend on your pulleys. DONT FORGET TO MAKE A BRAKING SYSTEM WITH CALLIPERS TO STOP YOU, THE BIKE BRAKES WONT HELP MUCH, so figure out how to add an old rotor to the rear wheel and a caliper use a makeshift master cylinder and you got your self a brake system. GOOD LUCK

Answer 3

Your quest for speed is not new. People have been using chainsaw engines to power vehicles for years. Go cart drivers/mechanics/engineers have made this into a science. They can get more power out a two stroke engine than you would ever believe. They can easily get 35-40MPH out of a stock engine. First of all, you can forget about welding brackets onto the chainsaw engine. They are aluminum block machines and you will ruin it if you try to apply that much heat to it. But, once you get the engine out of the chainsaw housing, you will find that there are already several mounting brackets, loops, etc. cast right into the block of the engine. The trick will be to build a bracket that will allow the engine to be bolted to the bike. The chain on a chainsaw is indeed driven by a sprocket and the sprocket is mounted on a centrifugal clutch, which is just what you need for your project. The "pitch" of the sprocket might be different from the pitch of he bicycle chain, so you will probably have to rig something up to drive the rear wheel. Chainsaw engines can be tuned to turn 10,000 to 14,000 RPM at wide open throttle without too much trickery. So, you will need some kind of drive system other than just the sprocket on the rear wheel of the bike. The engine won't have enough torque to get you going and once you got going you would go 1000 MPH turning 26" bicycle wheel that fast. When I was a kid there was gizmo that could be attached to the side of the bicycle wheel that was a giant V-belt pulley. It was almost the same diameter as the bicycle wheel itself. The motor then had a little pulley and a clutch on it. As I recall, we could get about 15MPH out of these rigs. But they were only about 2 HP motors and their max RPM was about 4,000. You will need something similar to this to "gear down" the RPM's to something usable on the wheel and to "gear up" the torque so that there will be enough turning force to move you when you are on board. The high tech term for this is a "transmission". The throttle on a chainsaw is usually controlled by a wire linkage that hooks directely to the trigger in the handle. But, in most cases, that could easily be rigged up with a cable. Good luck! Be sure to wear a helmet and possibly armor!

Answer 4

get 24 chainsaws, an 2 wheels

Answer 5

only thing i can come up with is turn the motor around but then it would prolly stick out farther than you want
ill get back to ya when i figure something out
