Location, location, location. No bicycle shop has a better spot than this gem of a place, and owner Mark Quinn knows it. "We're 100 yards from the trail," hesays, motioning toward the nearby Intracoastal Waterway, where bikers, joggers, walkers, and 'bladers cruise along a roughly four-mile paved path that takes them within ogling distance of some of the priciest and best-manicured real estate in the nation. But while the magnet for Quinn's shop is the Palm Beach Lake Trail, the friendly service and varied stock keep people coming back. "It's Palm Beach, and most people aren't looking to buy, so we have to do things kind of differently," says Quinn, age 41, who began working at the shop when he was 15 and bought it nine years ago. Doing things differently means giving customers the chance to rent a $2700 replica of the Trek bicycle Lance Armstrong rode to victory in the Tour de France. (It goes for $25 an hour or $99 a week) Or maybe it meansrenting bicycle-powered surreys that will accommodate two adults and three kids (also $25 an hour) or four adults and four kids ($45 an hour). But in addition to renting and selling expensive and novelty bikes, Quinn deals in basic beach cruisers, fixes flats, and sells the typical assortment of bells, whistles, baskets, and locks -- all at very non-Palm Beach prices. In that respect location isn't everything.
