The problem
A modern road bike runs on batteries. Lots of them.
Electronic shifters, power meter pedals, radar, lights, GPS, headphones, phone — that's 10+ batteries from 5+ different manufacturers. If any one fails mid-ride, your ride is ruined. And right now, there's no single place to check if everything is charged and ready.
The solution
BikeBatt is a pre-ride readiness checklist that lives on your phone. Open the app before every ride, work through the checklist, and roll out with confidence. It tracks battery levels, tire pressure, gear, and everything else you need to not ruin a ride.
Battery tracking
Log battery percentage for every electronic device. See what's charged and what needs attention.
Pre-ride checklist
Tap through each device before you ride. Progress ring shows how ready you are at a glance.
How-to-check guides
Each device includes instructions for checking its battery. Great for new setups or unfamiliar gear.
Battery life tracking
Track how long replaceable batteries last (SRAM CR2032s, etc.) so you know when to swap before a failure.
Gear packing list
Shoes, helmet, glasses, sunblock, nutrition — never drive to a group ride and realize you forgot something.
Tire pressure
Log front and rear PSI with target guidance. Beginners see recommended pressure; experienced riders track their preference.

- Shimano Di2 — single built-in rechargeable system battery
Built for cyclists, by a cyclist
BikeBatt was built out of the frustration of showing up to a group ride with a dead rear derailleur battery. It's a simple app that solves a real problem — and it's free.
