CatEye Velo 9 Bike Computer

The bike computer riders recommend most for the money. The CatEye Velo 9 is wired, so there is no sensor to pair and no charging, and its coin-cell battery lasts about three years while it tracks the nine things a commuter or beginner cares about: speed, distance, averages, time, odometer, and more. The display is big and easy to read, and CatEye reliability is legendary. It is bomb-proof, cheap, and does exactly its job, which is why it is the pick.

How this guide was made: I don't own every product I write about, and I won't pretend otherwise. Unlike the hands-on reviews elsewhere on this site, this is a research pick, synthesized from cycling communities like r/bicycling plus verified buyer reviews. It reflects the community's consensus, not my own testing. See how we research our picks →

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.
