When thinking of green modes of transport, the mind doesn’t immediately turn to motorcycles. Indeed, the essence of power-hungry road hogs couldn’t be much further from the environmentally responsible ideal. However, these nine bikes (and one trike) all have something in common: they’re made from recycled parts!9. Champion

Bolted together and with hard disk drives for wheels, the aptly named Champion isn’t likely to speed away from you, whatever it looks like! The bike is actually entirely made from recycled electronic parts, most of which are sourced from computers. Artist Alex Manigold, who describes himself as an “archaeologist of the future,” hopes that his sculptures will spread the message that electronics should be disposed of responsibly or be recycled. Coming in at the smallest bike on the list, you can’t say greener than that!8. Motorcycle

With an absolute guarantee of zero emissions and 100% recycled, this motorcycle, made by Bruce Gray, is amongst the greenest bikes that you can buy on this list. However, as a found object metal sculpture, it has a rather unfair advantage; though it incorporates a BMW R75/5 engine, it isn’t going to move an inch under its own steam. The wheels are made from two massive gears, which, with their gigantic teeth, are not going very far even if they were hooked up to an engine. In fact there is an engine, but it isn’t hooked up to anything. It’s a fine looking bike, though!7. Harley-Davidson Panhead and Trike (top)

These bad boys aren’t quite as mean as they look — in fact they’re works of art made out of recycled cardboard. Nevertheless, exquisitely realized by sculptor Chris Gilmour, they brilliantly convey the awesome power of the originals. Gilmour is an artist who specializes in making “translations from life” and takes pride in using everyday materials to immortalize the minute details of daily life. In fact, these cardboard road hogs almost look more impressive than the originals!6. Wooden motorcycle

There are motorcycles and then there are choppers, and here, for the ethical Hell’s Angel (not illustrated), is the electric chopper. Siemens, an electrical engineering giant, isn’t generally in the business of manufacturing motorbikes. However, for the American Chopper show, the firm made an exception, and, with the help of Orange County Choppers, it looks like they’ve made a good job of it. This 650-pound beast can hit 60 mph in six seconds, and has a top speed of 100 mph. What’s more, the entire aluminum shell is recycled. Beat that for environmental responsibility.2.
