Design for electric hybrid 4 wheeled bicycle with no chain or sprockets. Preliminary design and photos availab

Question

The easiest and quickest way to build a low cost, high performance vehicle is to assemble a “side-by-side” tandem bicycle. I am looking for a system that lets you snap itself together to make a four wheeler or unsnap it to allow for traditional, two wheeled riding. If interested, please contact for preliminary designs.

Looking for a simple design. Two 2 wheelers are "somehow" strapped together to ride as a 4 wheeler. The steering should be connected.

The link to the power assist site looks helpful. The link to the recumbent (Blackbird) I had seen before. I found it on a good four wheel site at: http://www.helmets.org/fourwhel.htm where I had already looked closely at their stuff. They are definitely on the right path; I am just not a big fan of recumbent bikes due to the low profile and exotic nature. The bicycle that I was considering using for the prototype was the Schwinn 2007 Electric Continental, Woman’s Version.

I prefer the woman’s version since it is easier to step through into the vehicle. If you look at the elegant design of the Schwinn, no sprockets, no chain plus front wheel drive, it seems to be a safe basis for a 4-wheeler kit prototype. The clasps and click-on features are probably available, off the shelf, from sailing, tenting or aircraft suppliers. (Lightweight, portable, strong, weather proof, idiot proof).

At the airport you have two bikes, a tent

Imagine being at your own airport. You have two electric bicycles and a click-together frame in a tent bag. Most airlines would accommodate you.

Answer 1

Blackbird bikes of Minnesota has something like
what you are talking about, but using recumbents:

However, to be street legal, it is going to be difficult; many states give a "bye" to low powered electric vehicles with 2 or 3 wheels, but few allow 4 wheelers without some extra safety equipment and insurance, licensing, etc.

Check your state and also reference Fed ebike law on google " electric bicycle HR 727".

What you are talking about sounds interesting, but dont know why you go without chains or sprockets, they are pretty efficient and cheap?

Interested in how you deal with Cof G issues and the "Ackerman effect" for front wheels turning.

Answer 2

whilst the is slanted a loose chain would slip to the backside side yet balanced on precise to the different side. yet exact adjusted the chain has no the place to circulate, centrifugal stress throws the chain removed from the sprocket on the backside yet pulls into the sprocket on precise.

Answer 3

Sounds interesting..............
