Authorized to service Shimano STEPS, Bosch, Fazua, Bafang, and SRAM electric drive units, MJ's Cyclery has run as Hillcrest's full-service independent bicycle shop since opening in 2014. As a stocking dealer for Marin and Scott — brands spanning mountain, gravel, road, and neighborhood formats — the shop performs contact-point fitting and saddle-positioning work that pairs with the cycling-injury treatment offered at Spine & Sport Physical Therapy on Fifth Ave for riders managing overuse pain. The service menu covers drivetrain adjustments and flat repairs on commuter hybrids through full suspension rebuilds and electronic-shifting calibration on carbon mountain bikes. Every new bicycle purchase includes five years of free basic maintenance covering brake, shifting, and alignment adjustments — a post-sale service structure that mirrors the repair-over-replacement culture at Coconut Peet's Surfboard Repair and Trading Co., LLC, where board-sport regulars return for precision ding work rather than swapping equipment. The shop accepts bicycles shipped in travel cases from out of state and rebuilds them in-house from the box for riders relocating to or visiting San Diego with gear already in transit.
