Ajo Bikes is a family-owned bicycle shop at 1301 E Ajo Way on Tucson’s south side. The shop sells Trek e-bikes and performs e-bike repairs with Bosch certification — a manufacturer-backed credential that covers diagnostics, firmware and drive-unit work on Bosch-equipped models. Conversion kits are also stocked, letting riders electrify a conventional bike they already own instead of buying new. The operation is a classic neighborhood shop: family-run, service-oriented, and built on repeat business from the surrounding community. Service is straightforward and dependable — a small team that handles repairs personally rather than pushing customers through a queue, with honest guidance on what a bike actually needs. Open Tuesday through Friday 10:00 to 18:00 and Saturday 10:00 to 17:00, closed Sunday and Monday. The shop’s south-side location makes it a convenient stop for riders in the surrounding neighborhoods. The published phone line is (520) 294-1434, and the shop’s site is ajobikes.com.
