Robert Egger is a designer at Specialized known for his off-the-wall design ideas. This bike is his “self shuttling downhill” bike.

There’s a nominally 49cc engine (to stay under California registration and license requirements) that Egger has bored out to 63cc. That motor putt putts the rider to the top of the mountain, and then he bombs down the hill. Note the branding, pedals, and mountain bike components such as disc brakes, forks, handlebars and suspension.

    I can’t decide–is that an overweight bicycle or an under-powered motorcycle?

    When I was riding mopeds in NH and NY, any gas engine under 50cc on a vehicle still required registration and a DOT approved helmet. So this doesn’t seem to be getting around that law, only that it may not be under motorcycle clarification which requires additional licensing.

    Dang, regular downhill shuttlers are bad enough..

    But downhill motor racing might be pretty cool, come to think of it.

    I just looked it up in California – 49cc engine doesn’t require registration but might require a “Class M2” license, but only for operation on the roads. Since this is for off-road use only, maybe not an issue.

    It is pretty obnoxious, isn’t it?
