Here’s a concept that looks interesting – a Porsche 911 bicycle by Dutch industrial designer Bastiaan Kok. It’s very motorcyclish for a bicycle. But then again, that’s to be expected when replicating the design of a Porsche 911.

It’s not electric. Pure leg power spins it. Bastiaan Kok has the frame and fork listed as single-piece aluminum alloy. That would make the bike unfortunately heavy. If actually built, by my guess-timation, carbon would replace the aluminum to cut down weight.

A headlight, tail light, and classic Porsche badge are integral to the frame. It rolls on Schwalbe Big Apple fat tires mounted to 5-bladed carbon wheels laced to some big ol’ disc brakes. The brake levers didn’t make it to this drawing, but they’re shown on alternate designs after the break. Pretty on the outside, most of the action seems to happen inside the frame where the bars and chain drive are mounted.

Bastiaan Kok describes the bike:

“Bicycle concept inspired by the classic lines of the famous Porsche 911. From the integrated headlight, through the slightly curved top tube, to the impressive rear wheel fender ending in the tail light. It all, undeniable, breathes the sporty and powerful impression of the Porsche 911 bodywork. The single piece alloy bodywork and front fork are manufactured using investment casting with a master produced by rapid prototyping. The benefits are a complicated shape (single piece) with excellent surface finish and integrated ultra thin ribs and all necessary bearing shells.”
