Under $100 you do not need maps and power meters, you need reliable speed, distance, and time that just works every ride. The big choice is wired (cheap, years of battery, no charging) versus a basic GPS (no wheel magnet, rechargeable). Look for the functions you actually read, a clear display, and long battery life at a price under $100.

A few things separate a good bike computer under $100 from a frustrating one: wired or gps, the functions you read, clear display, and long battery. Weigh these before you buy.
- Wired or GPS: wired is cheapest with years of battery; GPS needs charging.
- The functions you read: speed, distance, and time at minimum.
- Clear display: big digits you can read at a glance.
- Long battery: years on a coin cell, or enough GPS runtime for your rides.
