Precision MTB timing. Zero infrastructure.
Race for your pocket.
GravityGate turns any mountain bike trail into a race track. No gates to install, no phone signal required, no GPS guesswork — just clip the sensor to your bike and ride.
The problem
Strava tells you where you were. Not how fast you actually went.
Consumer GPS apps like Strava were never built for tight mountain bike singletrack under a tree canopy — signal drops, positions jump, segment starts drift by seconds. Professional timing gates solve that accuracy problem, but they only exist at organized races: bolted to a course for one weekend a year, run by marshals, gone by Monday. GravityGate is neither. It's built for the other 51 weekends.
Signal loss under cover
Trees and terrain block GPS exactly where it matters most.
Fuzzy segment starts
GPS-based splits can be off by seconds — an eternity in racing.
Pro timing needs a racecourse
Transponder loops and timing beams are genuinely accurate — but they belong to organized events, not your Tuesday evening lap.

How it works
One device. Zero setup.
GravityGate is built to disappear. Mount it once, then forget it's there — until you check your time.
Mount
Clip the GravityGate sensor to your bike in seconds. No tools, no calibration, no app fiddling before you drop in.
Calibrate
Ride the trail once, like normal. GravityGate detects the start and finish on its own and saves it as a new segment — timing runs automatically from that first recording on.
Recognize
From the next lap on, the sensor recognizes the trail by itself. Timing starts and stops automatically, every single time.
Share
Trails stay private or get published for others to ride. Your time hits your smartwatch instantly — shown on screen or read aloud — with the full breakdown waiting in the app.
Why GravityGate
Built for MTB trails, not the road
Everything about GravityGate is designed around one idea: racing should take zero effort to start.
Precise timing
Purpose-built for start-to-finish timing accurate to a tenth of a second — not a GPS approximation of where you might have been.
Fully automatic
Zero-friction start and stop. No taps, no menus, no distraction while you're on the trail.
Works anywhere
No trailside infrastructure, no cell signal, no Wi-Fi. Any trail, any time, anywhere in the world.
Race your friends
Compare runs, build leaderboards, and settle the debate about who's actually the fastest.
Async racing
No need to meet up. Set a time today, your friend tries to beat it next weekend.
Always ready
Mounted and armed. Jump on your bike and go — the timer is already waiting for you.
Your analysis
This is your coach.
Virtual splits, Ghost Mode, Video Matching, and precise timing don't just show you your time — they show you exactly where you lost it, right in the video. A whole team with a coach, that fits in your pocket.
Virtual splits
Drop split points anywhere on a trail, after the fact — and see instantly which section is costing you time against the leaderboard.

Race your run against another ride or rider, second by second — a graph shows you exactly where you gain or lose time.
Learn moreVideo Matching
Overlay splits and the ghost graph directly onto your video — see not just how much time you're losing, but exactly where and why.
Learn moreRacing mode
Start an instant race with your crew on the spot — times are compared live and roll straight into the leaderboard.

No trail day is ever wasted. Every ride counts, every run is timed, every friend is a rival — whenever, wherever.
Straight to your wrist
Your time, before you've even stopped rolling.
The moment you cross the line, GravityGate pushes your result straight to your watch — shown on screen or read aloud, no phone, no app, no waiting. Full splits and the leaderboard land in the app right after, whenever you want to dig deeper.
Illustrative animation — the actual notification depends on your watch and OS.

The app
Results waiting when you get back
Every run syncs straight to the GravityGate app — automatic splits, personal bests, and live leaderboards with your crew. Compete on the same trail without ever being on it at the same time.
Product screens are still in the works — this is an illustrative preview of the leaderboard experience, not the final UI.
