No Power Repair in San Francisco, CA
You press the power button and nothing happens: no display, no lights, no assist.
San Francisco riders deal with salt air off the coast, and one documented cause of this symptom is loose or corroded battery/display connector. It is worth ruling out first here, though it is one cause among several and not a diagnosis on its own.
San Francisco's hills are exactly why e-bikes took over here, and exactly why they need more maintenance than almost anywhere else. Grinding up Bernal Heights, Potrero Hill, or anything off the Wiggle loads motors and drivetrains, and the long descents back down burn through brake pads and rotors at a pace that surprises new riders. Fog and salt air rolling through the Richmond, Sunset, and Marina corrode exposed hardware, cables, and connectors, while winter rain washes lubricant off chains. Commuters run the Embarcadero, Market Street, Golden Gate Park paths, and across the Golden Gate Bridge toward Marin, often daily and in all weather. Hydraulic brake service, drivetrain replacement, and corrosion-related electrical issues are the most common jobs we see in the city, and mobile service means no wrestling a 60-pound bike onto transit.

Try this before you call
Before booking: confirm the battery is charged on the charger (indicator turns green), then reseat the battery firmly and try holding the power button for 5-10 seconds. Check for a small fuse near the battery mount or on the battery itself. If the charger light never changes color, the problem is likely the battery or charger, not the bike.
