BYB Chrono GPS Lap Timer – Precise lap timer for MTB, Motocross & Racing

Lap times you can rely on. The BYB Chrono is a GPS lap timer for MTB and motocross. It combines fast multi-band GPS with a wheel speed sensor and can be expanded with external triggers – allowing you to measure lap and sector times precisely, even where GPS alone becomes inaccurate.

Analysis is done in the BYB app for iOS and Android. This allows you to objectively see whether a line choice, setup, or technique change really makes you faster.
