Hey all

I am new here. I have a mongoose mountain bike I am planning on modifying. I was thinking a chainsaw engine with a clutch. Not sure if that will be underpowered or not. Also I want to keep the functionality of my pedals. This will be a low budget build so I don't plan to go crazy, but any suggestions and help is welcomed. Thanks for the input.

Welcome to the forum, glad you joined us.

Check out the Diy forum, lot's of great ideals and builds from other members.

Welcome to the fun!
I remember reading about a chainsaw bike on this forum and they did a good job of making that thing go.

Thanks. Yea I was thinking chainsaw or weed whacker, but the chainsaw engine would sit more flush with the frame. I don't want a big tumor on the bike, just something small that will keep moving me fast once I get going. I want to be able to hop up and off of curbs around school so I don't have to take the long way around.

I just bought this bike so I'm gonna start tearing it down and stripping unnecessary things. Reflectors and stuff. I used to ride bmx brake-less, but I am gonna keep the rear brake. Gonna see if there is a way to stiffen the rebound of the front damper as well. Then take some measurements and do some research.

Welcome You will find a wealth of info here! Just ask and we will help.
