Bicycle makers have recognized these problems for a long while, but few companies have attempted to address them. Organic Transit is the latest to take on this long-standing challenge. Its three-wheeled Elf adopts what’s known as the “tadpole configuration,” with two wheels in front and one in the rear. In this respect, it’s similar to many of the velomobiles that have come before it. But unlike most of those earlier models, it wasn’t designed low and sleek to slip through the air. Rather, the Elf’s designers had safety and comfort at low speeds in mind, which is why the rider sits high and why the plastic body of this vehicle is not particularly aerodynamic.
While the Elf is certainly cute and will provide an attractive way to get around for some people, I came away from my visit with Organic Transit a bit skeptical. To me, the Elf, small as it is by car standards, seemed way too big and heavy. (It’s almost 70 kilograms—150 pounds.) So you can’t, say, carry it up a flight of stairs as you can with most any bike. And forget about taking it someplace in or on your car.
