About this project

[Note: Video shows our prototype designs and configurations of the M.O.M. Trailer™ - final production trailers and Trailer Plug-Ins™ may incorporate changes (improvements!) to those designs.]

I’m Len Rubin. Those of you who may have followed my bicycle design projects over the years, read industry articles by or about me, heard me speak at bicycle trade shows, or visited any of my bike shops know that I’m passionate about removing barriers to the regular use of bicycles for daily practical transit and transport.

My latest project is what I lovingly call, “M.O.M.”™ (for “Multipurpose Overland Mover” ™)—an exciting twist on a traditional “loadbed” bicycle cargo trailer design [see Andy Hunter’s BikeBox, Nick Lobnitz‘s Carry Freedom Y Frame, etc.] that–through a system of versatile Trailer Plug-Ins™ –greatly expands the range of what can be easily and conveniently transported by bicycle (using a “morphing”, one-tool-does-it-all cargo trailer!) (our draft logo is below..)

We have a 1,200 square foot bicycle fabrication workshop at our home in Portland, Oregon. Using my current rudimentary tools— with some friendly assistance/use of additional tools & facilities from some bike-fabricator friends—I have produced three hand-built prototype trailers: 1) a first-generation proof-of-concept prototype, 2) a lighter and more streamlined second generation prototype, and 3) the current, third-generation prototype, which is even lighter than the 2nd-gen proto (while retaining its best-of-class 500+ lb. hauling capacity) and incorporates several additional refinements to the design. [Note: the second generation prototype was purchased by an enthusiastic beta tester (he’s a musician, kayaker, ER doctor and father of two young boys)]

In order to create the first limited production run, I need to build and document a proper "production" prototype and subsequent trailers using tools and techniques that ensure precision and repeatability. To do this I need capital with which to purchase additional tooling, equipment & supplies.

Also, I will need to make a pair of extrusion dies that my local aluminum tube supplier can use to produce the special telescoping tube pairs which are key to the trailer design. (For the existing prototypes, I had to import tube sets from Canada (both cost-prohibitive and “un-green”!), and then hand-file all mating tube pairs post-welding (oooh, don’t even ASK how many hours THAT took!) [We are extremely fortunate to have one of the leading extruded aluminum tube manufacturers in the world right here in Portland, so for the production units what had been a bit of a nightmare will actually be closer to a dream come true—both in terms of the economics and convenience/best-case environmental practice of truly local sourcing!]

Also, while I intend to eventually produce the trailers completely in-house, for any processes or components that need to be subcontracted initially, I am committed to using only local—or at least domestic—materials, suppliers and workers!
