Bike IQ 1.2: Apple Watch, Cadence Detection, BLE Broadcast, and Multi-Brand Radar
Version 1.2 is the biggest update since launch. Your iPhone can now detect cadence and gears on its own, your Apple Watch becomes a full ride companion, and Bike IQ works with more hardware than ever.
Apple Watch
Your ride, on your wrist. The new Apple Watch app mirrors your live metrics (speed, power, heart rate, cadence, grade, distance, elevation, and more) with configurable screens you can swipe through mid-ride. Turn-by-turn navigation signs appear on your watch using the same vector arrows as the map, so you never miss a turn even when your phone is in your pocket.
Full ride controls are built in: pause, resume, mark a lap, or hold to end. Heart rate from your watch syncs automatically whenever it's reachable, so there's no need to wear a separate chest strap if you don't want to.
Cadence and Gear Detection
Bike IQ now uses your iPhone's accelerometer and gyroscope to detect your pedaling cadence and current gear in real time. No extra sensors required. Just ride with your phone mounted or in your pocket, and cadence and gear data appear alongside the rest of your metrics.
The detection pipeline combines signal processing with your bike's gearing configuration to produce accurate, stable readings across different riding styles and phone placements.
BLE Broadcast
Turn your iPhone into a virtual sensor. With BLE Broadcast enabled, Bike IQ transmits standard heart rate, speed, cadence, and power data over Bluetooth Low Energy. Garmin, Wahoo, and other head units that support standard BLE cycling profiles can pick up your data just like a dedicated sensor.
A device trust system gives you control over which head units can connect. When a new device tries to subscribe, you'll see an approval prompt with per-sensor permissions, so you can choose exactly what data each device receives.
Multi-Brand Radar
Bike IQ already works with Garmin Varia. Version 1.2 adds support for six more radar brands: CYCPLUS, Giant, MagicShine, Magene, Trek, and Lezyne. If you own a rear radar from any of these brands, it now connects and works with Bike IQ's radar widget and alerts.
Garmin's Varia RearVue 820 and Trek's CarBack both get special treatment with full 2D target tracking: vehicle type classification, lateral positioning, and passing metrics that go beyond simple proximity alerts. All other brands integrate through the same familiar radar interface.
