Looking for a fun way to explore a city with teens? Consider two-wheeling it around town.
The long-awaited Citi Bike program rolled into the Big Apple last month and proved an instant hit, with nearly 12,000 New Yorkers signed up for annual memberships at launch. Since 2010, about a dozen U.S. cities have introduced bike-share programs, and Chicago is aiming to launch its own program in less than two weeks.
For visiting families with teens, bike-share programs offer a fun, affordable way to explore part of city. Don't want to deal with traffic? There are plenty of bike stations near parks and other car-free areas.
The programs we looked at in major cities work the same way. You buy a base subscription for 24 hours or more, during which time you get an unlimited number of 30-minute rides. If you go over your allotted half-hour ride time, you start incurring nominal fees for each subsequent 30-minute period.
Relax and roll with it, says Anthony Ongaro, marketing director of Nice Ride Minnesota, the bike-share program of Minneapolis. "Bike shares are designed so that you never have to pay for overtime if you don't want to. To avoid incurring fees, simply dock the bike in any station and then immediately check it back out and be on your way."
The bike-share programs we looked at offer excellent value for families that want to see a section of a city from the saddle of a bike. "If you'd like to take a bike out for a full hour, it would cost just $7.50 in total," says Ongaro of the bike-share program in Minneapolis. "After that, you could always take out another bike, as many times as you wanted within that 24-hour period, for a half hour at a time, at no extra cost."
