"Anyone who's ever gotten clothing caught in their bicycle gears and been sent tumbling to the ground with a shredded pant leg will surely appreciate a new bike that ditches the derailleur in favor of a safer, cleaner, lower-maintenance direct-drive system. Just introduced Stateside by importer Dynacraft, the Dekra D-Drive bike uses a drive shaft to transfer power from your pedal-pumping legs to the back wheel, and includes a fully enclosed bevel gear system from Shimano to ease your load on those uphill climbs. Of course, with only three gears (changeable through a twist of the handlebar), this model will never be seen cruising victoriously down the cobbled surface of the Champs-Elys&amp;eacute;es at the end of a Tour de France, but at $300 it seems like a reasonably-priced way to roll around town hassle-free.[Via Gizmag]"^^<http://www.w3.org/2001/XMLSchema#string>
