Cat Woodmansee didn't want to commute by car or train, but the 50-year-old Silicon Valley software engineer wasn't up to pedaling his bicycle 60 miles a day either. So, using a kit, he added an electric-assist motor and battery pack to his Electra Cruiser 7D, a standard bike.

Since the Scottish inventor Robert Thomson patented pneumatic tires in 1845, they have become standard on every vehicle with two, four or 18 wheels. Pneumatic tires are now so durable that many drivers never even bother to check their air pressure. But the tires still have weaknesses, not least of which is the tendency to go flat.
Since the Razor came out in the U.S. in the late '90s, inventors have tried, with varying success, to create the next generation of kick-powered conveyance. Now a Nevada start-up aims to beat the Razor in both maneuverability and stability. The Sbyke is a BMX bike mixed with a skateboard. The company claims that the fixed 20-inch wheel allows its scooter to negotiate uneven surfaces better than a Razor. It also says its novel rear-axle mount, which uses ball bearings that let the axle turn up to 50 degrees in either direction, makes the Sbyke the nimblest scooter yet—one that can purportedly execute tight four-foot turns.
Amphibious vehicle designs always sounds great on paper, but in practical use they tend to sink more often than swim. It’s not so much that they don’t work, but that they tend to handle either land or water well, with the other being an afterthought (not to mention they solve a problem that most people simply don’t have). But we’d be lying if we said the Iguana 29 didn’t catch our eyes this afternoon.
