It's a place visited only by those who know its tucked-in-the-mountains whereabouts. Downieville, on the Yuba River, has a Main Street that's a throwback to the 1950s: kids circling on their bikes, dogs trotting down the sidewalks, and an old-fashioned tune-tooting ice-cream truck. This former gold rush boomtown offers multiple ways to kick back and lounge, including staying at The Lure Resort, a new hideaway right along the North Fork of the Yuba River. The Lure's eight log cabins were built from pine trees, and they have a full-size platform and bunk beds; campers bring their own bedding. (Lure also offers more upscale cabins, with kitchens and all the amenities.) A day's itinerary could include tubing the river, fishing for rainbow trout, or hitting the area's epic singletrack. Intermediate and advanced mountain bikers can whoop it up on the 15 miles of notorious Downieville Downhill. For more mellow singletrack, try the North Yuba Trail. Two bike shops in town rent bikes and run shuttles to the start of some great trails. Whether you're river tubing or mountain biking, save time afterwards to sample some rare reds at 49 Wines, right on the town's main drag.  Downtime, delivered.

The Lure Resort, 100 Lure Bridge Ln. at Hwy 49, Downieville; 530-289-3465. Camping cabins are $75 per night and hold up to four people. Dogs are permitted for another $20 per night. Rent mountain bikes and schedule shuttle rides from Yuba Expeditions or Downieville Outfitters.

Mike's Bikes, the Bay Area's premier bike retailer, wants to help you find the answer to this summertime question: what's your bike personality?
This week's bike personality: The All-Purpose Adventurer.

You want it all: Rocky trails, gravel paths, and coastal bikeways. You like comfort and flexibility when riding the rolling hills in China Camp and think fat tires are perfect for a Sunday afternoon spin around Golden Gate Park. The sights, the sounds, the feeling of being in the woods on a bicycle is your cure-all for stress. Yes. You want it all.

Sound like you? You're "The All-Purpose Adventurer." And the Mike's Bikes ride for you: the Cannondale F6. This jack-of-all-trails can take on whatever you feel like throwing at it. Reliable and strong, the Cannondale F6 is also lightweight, with a Rock Shox suspension fork that gives you confidence taking on the singletrack in Marin or the wide fire roads at Wilder Ranch. And you'll love the lockout, allowing you to turn off the suspension on your way to the trail. Dependability is the name of the game with the Cannondale. So go ahead: take on any terrain. Double-dare.
