There's no denying that Denver's B-cycle bike-sharing program is a boon, but what if, instead of B-cycle's somewhat pricey, one-size-fits-all model, you could borrow a bike that's just your size and style and ride it for free for the first two hours? That's the difference at Visit Golden's bike library, located at the downtown Golden Visitors Center, where your whole family can hop on a bike from 9 a.m. to 3 p.m. Thursdays through Sundays during the summer and fall months. Daily rentals beyond the two-hour period top off at $10, and there are provisions to return bikes after hours if you want to stop for dinner. Each bike comes with a helmet, a lock, a free water bottle and a golden ticket offering discounts at Golden businesses. And even if it's more of an amenity for tourists and not really intended for use by hard-core daily commuters, a deal's a deal.
