Simple Spin Pro turns your Echelon bike into a serious training tool — or the perfect companion for streaming rides. One app, two ways to ride. Build the exact interval session you want in about a minute and ride it while your bike changes its own resistance to match. Or keep your metrics on screen while you watch Netflix, YouTube, and more. Add a Bluetooth heart rate strap and see your heart rate live, too. THE SMART WORKOUT WIZARD Pick a shape and Simple Spin Pro writes the intervals: • Repeating — the classic work / recovery session • Progressive — every round a little harder than the last • Pyramid — climb to a peak, then come back down • Custom — build it interval by interval Then choose how round length moves: the same every round, longer, shorter, or up to a peak and back. Nothing starts blank. The whole workout is there before you change anything — named, rated for difficulty, and drawn as a profile you can read at a glance. YOUR BIKE FOLLOWS THE WORKOUT • Every interval applies its resistance to your Echelon the moment it starts • In Power mode, Simple Spin Pro reads your live cadence and calculates the resistance needed to hold your target watts • Spoken cues announce what is coming before it arrives • Adjust up or down mid-ride — your saved workout stays exactly as you built it LIVE HEART RATE Wear any standard Bluetooth heart rate monitor and your heart rate rides with you: • Live BPM in both structured Workouts and Just Ride • A heart rate trend across your workout profile • Average and max heart rate for every ride and every interval • Saved to Apple Health with your workout • Connect once — your strap reconnects on its own next time Most straps connect to only one device at a time. If yours will not connect, make sure it is not already connected to your watch, another phone, or another app. MAKE IT YOURS • Add an interval anywhere, delete one, or change its type, length, or target • Tap any value to set it exactly • Train by Echelon resistance, 1 to 32, or by watts, 10 to 500 W Edit anything and difficulty, profile, name, and spoken coach announcements all keep up. BUILD IT. RIDE IT. KEEP IT. • Tap Save & Start Ride and you are pedaling the workout you just built • Every workout is saved to your library • Share a session with a friend, or import theirs, from a single link • Workout history shows your consistency over time • Every completed ride syncs to Apple Health automatically RIDE AND STREAM Watch Netflix, Apple TV, Prime Video, YouTube, and more while your cadence, resistance, and power stay visible in rock-solid Picture-in-Picture, foreground or background. JUST RIDE Not every session needs a plan. Just Ride gives you live metrics and nothing else: cadence, resistance, power, heart rate, speed, distance, calories, elapsed time. BETTER TOGETHER: SIMPLE INSIGHTS Your subscription also unlocks Simple Insights, our companion app for deeper Apple Health–powered analysis of trends, training load, and progress. Same Apple Account, no extra purchase. KEY FEATURES • Purpose-built for Echelon Bluetooth smart bikes — connects in seconds • Your own structured workouts, with no class subscription and no instructor • Automatic resistance control throughout every structured ride • Power-based and resistance-based training modes • Live heart rate from any standard Bluetooth heart rate monitor • Zero ads, zero distractions UNLOCK EVERYTHING WITH PRO The Smart Workout Wizard and full workout library, automatic resistance control, background Picture-in-Picture, and Simple Insights access.
