Common Super73 Issues We Fix in San Marcos

Controller failures & no-power

S2 and RX controllers can fail from heat or water intrusion. We carry replacements and can reprogram modes on-site.

App pairing & speed limit unlock

We help with the Super73 app, firmware updates, and Class 1/2/3 mode configuration.

Flat fat tires

Super73's 20" x 4-5" tires are a specialty flat - we stock the right tubes and CST/Vee Rubber-compatible patches.

Brake upgrades & bleeds

Many riders upgrade Super73 brakes for the extra speed. We install and bleed Magura, Tektro, and Shimano hydraulic systems.

Battery diagnostics

The 48V Super73 battery and BMS often need a proper load test before being replaced - we do this on-site.
