NO SWEAT

Ford Motor Company’s Th!nk Mobility division has come up with a foursome of electrically powered bikes and on-road vehicles that get you where you want to go without the legwork and without polluting the environment. Two bikes, the foldable-frame Traveler ($1195) and fixed-frame Fun ($995), have power at the ready when you need help on the hills or for going long distances; both function as regular pedal bikes when the motor isn’t engaged. The Traveler can go up to 16 miles, at a top speed of 18 mph, before it needs recharging. Fun lasts for a little longer: 22 miles at a top speed of 20 mph.

The two- or four-passenger Th!nk Neighbor ($6,000) travels the ’hood at a top speed of 25 mph, and needs recharging after 30 miles. Ford proposes commercial applications, such as maintenance and security. Look for the two-passenger City on streets near you, traveling up to 56 mph for 53 miles before needing to be plugged in.
