Four Wheeled Modular Bike Part Helicopter Cart Upcycle Welded with the Trenton Atelier, Partially Dismantled with Baltick & Winckel and Other Assorterd "Hangers-On," Dude

The main problem we are having right now is finding a way to make head tubes to hold the bearing assembly in place. For the first generation we cut off the bike from the tube and grinded down the rough parts. That's a lot of waste and time for de-engineering to get a needed part. Basically to make a head tube we need to expand the ends of a 1" tube to hold the bearings.


Here is a pic of the base in the process of being made, first generation.

The cart needs to be modular and be able to fit into the trunk of a car. It currently has that capability.

There exists a horizontal slide-in system for the wheels and housings and there is too much torque at those points.

I think we want to use a vertical slide in system, see my diagrams, and put a little more depth on the frame at the points where they are attached so the torsional stress is removed.

It would be nice if the frame hinged in the center from the underside and could be folded in half. It currently is made of 2 halves and then bolted together in the center and along the sides with supports.

Engineering for the steerable fork housings.

It has been suggested that rather than use the double plates on the fork to use a rectangle piece of steel over the top of the fork tube. Hmm. . .

This is the engineering I see for the fixed forks.

This was the Wilking Heli Shuttle on its maiden voyage at the Winkel and Balktick New Year's Eve Party in New York.

And here is the groovy aftermath from the party.
