Trek Bicycle South Bay in Bonita carries the full Trek and Bontrager lineup — road, mountain, hybrid, and electric bikes — from a Bonita Road showroom near the Sweetwater Road corridor. In-store fitting sessions use Trek's Precision Fit system to dial saddle height, handlebar reach, and cleat position, the same biomechanical markers refined through reformer work at Club Pilates Bonita for active cyclists. Founded in Waterloo, Wisconsin, in 1976, Trek now operates retail locations across the country; the Bonita store serves as the South Bay flagship with 24-hour service turnaround on bikes of any brand. A three-tier maintenance program starts at $99.99 for brake and shifting adjustments, scales to $189.99 for drivetrain deep-cleans and wheel truing, and tops out at $449.99 for full teardowns including cable, housing, and bearing replacement. The Red Barn Refresh trade-in program applies credit from older Trek frames toward new builds, a turnover cycle that keeps riders on current geometry — and the spinal and extremity adjustments at Gerken Family Chiropractic keep those riders pedaling pain-free between upgrades. The Level Three strip-down replaces all cables, housing, and bearing systems, services front and rear suspension wipers and seals with fresh oil, and delivers an advanced lateral and vertical wheel true to bring the complete drivetrain back to factory tolerances.
