While it won't go over with the biking cognoscenti who prefer a polished Italian-made drivetrain, the occasional leisure cyclist may find this a fun toy along the lines of the suitcase bike.
Hammacher Schlemmer is selling a chain-free 3-speed called the Belt Drive Bike for $500
As it says in the name, the bicycle has a lube-free Kevlar belt in lieu of a bike chain. The company claims that its lightweight and grease-free belt system needs no tension adjustment, and will not slack or slip.
Ergonomic adjustable 9-inch seat, 19.75-inch aluminum frame, and 26-inch tires with stainless steel spokes and alloy hubs and rims make up the rest.
Might be a cute bike to leave at your parents' summer house...Or your own summer house for our dot.com millionaire readers out there.
If, alas, there is no summer house anywhere in your orbit, then you probably don't need to spend $500 on a non-slacking bicycle just to tool around on.
