Allert Jacobs is a Dutch vehicle designer who doesn’t like to buy gasoline very often. Dissatisfied with his Honda Innova’s 114 mile per gallon fuel economy, Jacobs thought he could do better by improving the bike’s aerodynamic profile. His first designs didn’t work well enough, so he built a 1:5 scale model and went back to the wind tunnel. Ultimately satisfied with his revised prototype’s design, Jacobs built the fairing you see here from steel tubing and fiberglass, and dubbed his creation the Aerocycle. Looking to squeeze out the last few mpg, Jacobs even converted the Innova’s transmission from an automatic with a centrifugal clutch to a manual.
His design works so well that he achieved 214 miles per gallon in the Aerocycle on a recent trip. As an added bonus, the fiberglass shell locks in place, allowing him to secure any valuables inside the bike’s fairing. Jacobs has uncovered one flaw with his design: the narrow fairing doesn’t allow for a wide placement of the riders legs at a stop, potentially creating tip over issues. Jacobs is considering an open sided version to correct this.
Honda doesn’t import their Wave series of motorcycles (which includes the Innova) into the United States, since low horsepower, small displacement bikes haven’t sold particularly well here. Still, It makes we wonder what I could do with a Kawasaki Ninja 250, some steel tubing and fiberglass sheets.
