When BMW launched the enclosed motor scooter in 2000, the initial public response was one of smiles and amazement. The protection it offered from the elements, as well as its passive safety features, won over legions of commuters and city-dwellers. But for many potential customers, the C1 was simply underpowered and rather unattractive in design. So the BMW designers and engineers began experimenting with more far-fetched ideas. These included the Baywatch model, which featured a jet ski attached to one side like a motorcycle sidecar. Another experimental variant came with a rear propeller and detachable wings for use as a light aircraft. But the most sensible BMW C1 was a lean, lightweight version that moved faster, sounded better and looked sharper. Despite the wealth of ideas, production of the BMW C1 was mothballed after only three years, with sales of just under 35,000 units. Nevertheless, it left behind a loyal fan base and a promising concept. So a revival is not beyond the realm of possibility.
