Folsom Bike’s experienced bicycle technicians rehabilitate cycles and pair horseless riders with trusty two-wheeled rentals. During basic tune-ups, pedal physicians pamper asphalt steeds from headset to hub, remedying aches from popping wheelies with derailleur, brake, and bottom-bracket adjustments and ensuring optimal tire pressure and bolt safety. Creaky cables relax under soothing lubes, and newly trued wheels make for rides smoother than a piggyback from a manta ray. During performance tune-ups, gear gurus raise the velocipedal ante with fresh cables, housings, and frame polish before resurfacing brake pads, overhauling brackets, and weaving handlebar streamers into aerodynamic cornrows. Both basic and performance tune-ups are typically complete within 24 hours.

For those looking for temporary transportation, 24-hour bike rentals perch riders atop mighty Giant Escapes, which slip seamlessly from city streets to off-road obstacle courses. The rental also equips noggins with complimentary helmets, protecting delicate pompadours on excursions down the more-than-30-mile American River Parkway Trail or joyrides around the city’s parks and local trails.
