I am looking to start a new project this spring to replace my aging 2-stroke 66cc bike and have something faster and more reliant (4-stroke). I am really keen on the idea of a 125cc lifan motor and I love the look of fat tire bikes. Here is my plan.
- 125cc lifan manual 4up, 1down motor with a 26" fat tire mountain bike with disc brakes
- the lifan motor has two mounting bolts on top and back of the engine
- the back bolt will be mounted to the seat tube
- the top bolt will be mounted to a metal fabrication that connects to the top tube and seat tube for support
- the bottom tube of the bike will be cut as needed
- hopefully once things are mounted and working, i want to reinforce the cut bottom tube
While I don't like the idea of cutting the bottom tube to fit the motor, I've seen this done before to a bmx bike where bot the bottom and seat tube was cut/ missing. I am thinking that as long as I am not jumping large hills and if I reinforce the missing bottom tube I should be fine.
What do you guys think? Am I going to ruin a perfect fat tire bike and have to resell the motor. Haha. Pitchy I know you are looking for stronger engines too. Here is the YT video of the guy with the lifan motor on a bmx bike with the bottom and seat tube missing.
