Remember, gears may depend on the location of your college campus. If your campus is located after the mountainous area, you should have the ability to pedal uphill. In this situation, you will need multiple gears. Several bikes are available single- and triple-chairing options along with 7-, 8- and 21-speed cassettes. For a college in a flat town, you can buy a single-speed bike or a 3-speed model. For a hilly, sprawling campus, you will need an e-bike.
