At 303 Bike Shop, we provide professional bicycle service and repair for both traditional (acoustic) bikes and electric bikes. Whether you ride daily or seasonally, proper maintenance keeps your bike safe, efficient, and enjoyable to ride.

Our Denver-area service department works on everything from basic tune-ups to advanced diagnostics.

Acoustic (Traditional) Bike Repair

We service all types of traditional bicycles, including:

• Gravel bikes
• Road bikes
• Mountain bikes
• Touring and commuting bikes
• Steel, aluminum, and carbon frames

Our acoustic bike services include:

• Tune-ups and safety checks
• Drivetrain service and replacement
• Brake adjustments and upgrades
• Wheel truing and bearing service
• Suspension maintenance
• Cable, housing, and component installs

We believe traditional bikes should be repairable, not disposable—and we take pride in keeping quality bikes on the road for the long term.

Electric Bike (E-Bike) Service & Repair

Electric bikes require specialized knowledge and tools. Our technicians are experienced with e-bike systems, including:

• Motor and battery diagnostics
• Firmware updates (where applicable)
• Brake and drivetrain service for higher-torque systems
• Safety inspections
• Routine maintenance and wear items

We service many major e-bike brands and focus on practical, honest assessments—so you know what’s needed and why.
