ZoneCycle

The whole screen is your zone

You don't read a number mid-sprint. ZoneCycle turns the entire screen the color of the zone you're in, so a glance tells you whether to push harder or back off.

Gray 50%Blue 61%Green 71%Orange 84%Red 92%

Five zones, set from your max heart rate and fitness level. Push intervals want orange or red; recovery wants green or below. A voice coach calls every push, recovery and countdown out loud, so you can look at the bike instead of the phone.

What's in it

• Six voice coaches. A stern sensei, a drill sergeant, a Southern sweetheart, a no-nonsense NYC trainer, a zen gym bro and a Cali surfer. Or silence.
• Push Power Score. One number for the work that matters: total watts produced during your push intervals. Beat it next time.
• Proven protocols. 10/40 and 20/60 push-and-recover cycles in 5, 10 or 15 minutes. Warm up, work, cool down, done.
• Recovery tracking. Your heart-rate drop 60 seconds after the last push, the fitness marker that improves fastest.
• Live bike data. Watts, RPM and calories from any Bluetooth FTMS fan bike. Heart rate from any Bluetooth chest strap.
• Works without gear too. No devices? Timers and voice coaching still guide every interval.

How a workout goes

1. Put your strap on and wake the bike. Tap to connect each one, or ride with neither.
2. Pick a coach, a duration and an interval type.
3. Start. The screen and the voice do the rest. When it ends you get your score, your power output and your recovery.

Your data stays yours

ZoneCycle talks to your bike and your heart-rate strap over Bluetooth and to nothing else. No account, no cloud, no analytics, no ads. Workouts are stored on your phone. Privacy
