Please allow me to introduce.... Stacey's Mom.

A convertible tall bike/chopper build that is just for fun. See the full details in the build thread.​
 
This is a cool project that I saw online a couple of years ago. It looked like fun and potentially a project I could handle so when a free 24" mountain bike came up around the beginning of this build the die was set. Here's the starting point. The shop inspector approves.

After disassembly I cut the swing arm off and broke out the fab tools.

Added some scrap tubing to stretch the swing arm a very precise amount of... well, it's stretched. :grin:

The name of the build came about as that song was inexplicably playing on repeat in my head while I was welding the frame.

I used the fork from a department store 26" mountain cruiser so I could have a little bigger front wheel. I had a rusty old piece of pipe that looked about the right length so I lopped it in half and welded into the forks for the perfect extension.

Looks ok. This might actually work!

The mock-up looks really good.

This design uses gas struts as the mechanism to convert the bike between a chopper and a tall bike. Got some basic struts from the jungle website and fabbed up some attachment points.

A lick of paint and some final assembly and it's a bike again with a lot of extra fun built in!

With a degree of trepidation I put on all the padding I could muster and climbed aboard. Oh, boy. What have I gotten myself into.

This bike was super fun to build and it's a real kick to ride. I'd highly recommend it to anyone who might be interested in building one. Check out my build thread for details. :113:

Fun watching this fantastic contraption come to life. Looks like you had a great time with it and it came out cool. Great name too!
 
Man! To take it from what you started with to where it is now blows my mind! :oops: And then YOU RODE the dang thing!!

Incredible amount of geometry, engineering, and work into this one. Kudos! :praise:

Thanks Chad! If I'd had enough time I would have polished everything to perfection. Nah, you're right, probably not. :grin:
Seems obvious the helmet is so you don't bump your head on the soffit when mounting. Gutsy and creative!
True that! I did have to watch my head there. 🤪

Thanks OJ! I can't take credit for the design or math, in fact I barely did any measuring. I'm happy that the frame and forks both came out pretty straight and it rides really well. I won't be heading off road with this one but, wow, it's really fun to ride! :cool2:
