Before Your First Ride
Check the seat, gears, and tire pressure. Proper tire pressure can avoid flat tires and improve performance, including distance
traveled per inflation.
Check the handlebar and screws at least once a week.
Performing the above routine checks before and after each ride can help you keep your bike at peak performance and spot potential
problems before they become safety hazards.
