I unfortunately never got to finish my donkey bike in the main build off due to many reasons
Main one being I couldn't get the bike to be 4 ft or less in length
Ironically at the same time I picked up this used mongoose zam bmx styled scooter to use at work
I removed rear hinge foot brake when I first used it so it's just an empty space on the frame

One of the things that I discovered about this frame is the fact that the frame is not fully welded

I think it was done to make it fight in smaller shipping boxes

Definitely not something that I want to keep using even if it's just back and forth from where I have to park
But it's the perfect platform to build something compact and donkey bike inspired

Here is the frame after being unbolted

I decided since I at some point want to still build my donkey muscle bike donkey Kong
I needed something to set this bike apart
Therefore I will be running an 18" rear wheel
Correct me if I'm wrong but I had read that one of the things that makes them pit bikes are having wheels smaller than 20"
Usually 16"

This bike will be using a tire 18x3

It's going to require removing 2 small brackets in order to clear but nothing major

Here you can see the rough mock up of where I am planning on putting everything
Total length is estimated at 40"
Just need to shorten that excess tubing from the middle

Came up with this idea late in the weekend
Unfortunately I could only find one rear rack to use as a mock up
I thinking of using it to fill the upper gap between the seat and the front of the bike
I have other rear racks I can dig out this week or check my local co-op to find any that fit best
