Setting Up Your Bontrager RideTime Computer Without Losing Your Mind

The RideTime cycling computer from Bontrager is fairly straightforward once you get past the initial pairing dance. I've spent more time than I'd like to admit wrestling with Bluetooth LE sensors and re-pairing sequences that should have worked the first time. This guide covers what actually matters. Before you even think about turning the unit on, make sure your phone is running iOS 14 or later, or Android 8.0 with Bluetooth 5.0. Anything older and you're going to have a rough time. The RideTime app itself is free on both the App Store and Google Play. Download it first, create an account, then power up the computer by holding the center button for three seconds. The screen should light up with the Bontrager logo and then go to the main display. Pairing happens through the app, not by holding buttons on the device like some older units. Open RideTime, tap your computer icon, and it should appear in the available devices list within about ten seconds. If it doesn't show up, toggle Bluetooth off and on again on your phone, then restart the app. This solves roughly eighty percent of pairing issues I've seen on forums.

Configuring Sensors and Display Layout

Once paired, you'll want to connect your cadence and speed sensors if you have them. The RideTime supports ANT+ and BLE sensors. I ran into a situation last year where my Wahoo cadence sensor would connect fine but drop out after about twenty minutes of riding, especially in cold weather below forty degrees Fahrenheit. The workaround was switching it to ANT+ mode instead of BLE, and the drops stopped completely. Temperature seems to affect BLE radios more than ANT+ on this unit. For the display layout, you can customize up to five data screens. Go into the RideTime app, select your computer, and tap Display Settings. Each screen lets you pick from speed, cadence, power, distance, time, heart rate, and battery level. I'd recommend keeping one screen simple with just speed and time for casual rides, and another with cadence and power if you do structured training. The battery level indicator on the computer itself is fairly accurate but tends to drop in sudden steps rather than gradual decreases. Don't be fooled into thinking you have more juice than you actually do once it hits twenty percent.

Common Pitfalls and Things That Won't Work

One thing most people miss is that the RideTime does not store ride data locally in any meaningful way. If the app loses connection mid-ride or your phone dies, that ride is gone. There's no onboard storage backup like you'd find on higher-end Garmin or Sigma units. You need your phone present and connected the entire time. This is a significant limitation if you ride in areas with spotty cellular service and rely on your phone for anything else during the ride. Another issue is firmware updates. Bontrager pushes them occasionally, and while they generally improve stability, I've seen the unit become unresponsive after an update on at least two occasions. The fix is a hard reset: hold all three buttons simultaneously for ten seconds until the screen goes black, then release and reboot. I did this after a firmware update bricked my display during a group ride. Embarrassing, but it worked. The GPS on this unit is also mediocre at best. It takes roughly forty to sixty seconds to get a satellite lock on a cold start, and accuracy degrades noticeably under tree cover or between tall buildings. If precise route tracking matters to you, pair it with an external GPS pod or just use your phone's GPS through the app instead. The built-in GPS is adequate for basic distance and pace but not for anything requiring trail-level accuracy.

Advanced Setup: Power Meter and Training Peaks Integration

If you're using a power meter, the RideTime handles FTMS (Fitness Machine Service) profile connections, which means you can stream power data to third-party apps like TrainerRoad or Zwift without needing a separate ANT+ dongle. Set this up in the app under Connected Apps. Pair your power meter through RideTime first, then enable the FTMS gateway. It usually takes about fifteen seconds to establish the connection after that. Training Peaks sync is available but one-directional. Rides upload to Training Peaks automatically after you finish, but workout downloads from Training Peaks won't push to the RideTime display. You'd need to manually program intervals through the RideTime app if you want them on the unit itself. This is fine for casual riders but limiting if you follow structured training plans.

When the RideTime Isn't the Right Call

The Bontrager Ridetime Cycling Computer Manual covers all of this, but the manual itself is thin on troubleshooting. If you need a device with local data storage, multi-band GPS, color displays, or navigation capabilities, this isn't it. At this price point, you're getting a basic computer with app dependency. For riders who want simplicity and don't mind carrying their phone, it works. For anyone who wants a standalone training tool, look at the Garmin Forerunner 255 or even the Wahoo ELEMNT Bolt v2. They cost more but solve most of the limitations I mentioned above.
