Because I had built essentially the same design the previous year (see Gitche Gumee Tadpole), this build went very smoothly and quickly. [As always, a big Thank You goes out to Atomic Zombie DIY bike projects for providing the plans for this project! Note: I utilized Atomic Zombie’s step-by-step “Hammerhead Winter Trike” plans for this build. These plans can be found online and in AZ’s “Bicycle Bonanza” book of plans.]
The goal was to create a monster-sized tadpole-design three-wheeler with the aesthetics seen on the mutant vehicles depicted in Mad Max: Fury Road (2015).
The monster size was achieve by utilizing the frame and rear drive train of a 26″ Mongoose Beast All-Terrain Fat Tire Mountain bike and the front ends (forks, wheels and tires) of two 32″ Genesis Super 32 Cruisers. [Yes, I had these laying around the shop.]
The Mongoose Beast I found on Craigslist a couple years previously for less than $100. Because of the tall profile (sidewall height) of the Beast’s tires, the overall tire’s outside diameter matched that of the Genesis Super 32’s tires.
One of the Genesis Super 32’s I purchased new online for $179; the other I picked up at the Kiwanis Bike Program for $100.
I had already used the rear wheels of these two bikes for another project [in process], so I needed to find a home for the two front wheels anyway.
As the name implies the Genesis Super 32 features 32″ wheels! The size of these incredibly tall wheels really need to be seen in person to be truly appreciated.
[Note: In actuality, despite the marketing of “32”, the outside diameter of the tire is closer to 31″ than 32″; but still, these suckers are huge.
I also utilized the handle bars and stem from one of the Super 32’s; and saved the chains and seats for parts. But because the frame is aluminum (as opposed to steel), there isn’t much I can do with the frame (from a weldability standpoint), because the welder I use can only weld steel.
So, unfortunately, the two Super 32 frames may have to become scrap. [You never know though — a project may present itself.] [And, in fact, at the end of the steps of this build you’ll see that the rear fenders were also modded and utilized. – Ed.]
