CPHBS: Legendary

Twas the Wednesday before finals week, and what do I see but but a bunch of M.E's on their S.T.V's.

Single Track Vehicle design is class offered every year by the Mechanical Engineering department here at  Cal Poly.  In this class they spend a considerable amount of time gaining a theoretical understanding of lean to turn vehicle handling characteristics.  After writing scads of MAT Lab code, tedious hours of homework and laboratory inertial testing; they get to build their own bike, and today was their final day to show them off.

Some of the more polished bikes were able to use the SLO Bike Kitchens frame prep tools and many others made use of our bargain basement frame supply.  Amongst the crowd were bikes of all varying levels of completion and construction quality.

Now without further adieu, here are some of the standouts.  All of these pictures were taken by Rory Aronson, and can be viewed here.


Blaire's fully bamboo bike, only sporting metal bits in the BB, headtube and rear dropouts.  I believe that it weighed in at about 23 pounds.  This might have been my favorite project as he ended up with a beautiful project and did not have to sweat waiting for the on TIG welder available at any given time, which was limited.

Rory's cargo recumbent, which was another back yard project.  This bike was surprisingly stable, especially at low speeds, due to the low center of gravity. The only design issues that still need resolving are the steering linkage and chain line off of the jack shaft pass through the cargo compartment.

A beautiful 70% wooden bike, this was another of the projects prepped at the SLO Bike Kitchen.


Me goofing off on my triple tall.

Once the professor had ridden their bikes, many of the students bolted to finish the design reports that were due by Friday.  Good luck gentlemen.
