Creating the steering tube

Typically, when converting a bicycle to a three-wheel tadpole design, the bike’s original fork is chopped to create the steering tube to which to connect the tie rods.

However, because the main bike was a “fat tire” bike with a front fork that fit a 4-1/4″-wide tire, I chose to save the fork (and wheel).  […for some other project TBD.]

…And so it was off to my parts bin to find a new fork that would fit the Beast’s head tube.

Unfortunately I did not possess the correct size. So, it was off to the Reno Bike Project to find a fork to fit. As you can see from the picture below, the Reno Bike Project has a little more variety in forks than I do.

I found one that fit for $10.  Love Reno Bike Project! ♥

Then the connector plate for the tie rods was welded onto the bottom of the steering tube.

Btw, detailed step-by-step plans for building a “tadpole” design trike can be found in Atomic Zombie’s “Bicycle Bonanza” book of plans.  Note: I utilized Atomic Zombie’s step-by-step “Hammerhead Winter Trike” plans for this build.  A BIG Thank You to Atomic Zombie.
