Bike computer for e-bikes
Motor and battery data, your own effort and a bike history to show a buyer.
Free during launch. No subscription. For iPhone and Android.
01 Performance · Know your ride
An e-bike computer with live data. With a supported bike, the ride screen splits the work in two: your watts and the motor’s. After the ride you see your share and how the assist was spread across the modes.
After the ride
The route, the elevation profile and the numbers from each ride.
The sculpture behind the phone follows the elevation profile on the screen. Example data.
Every ride
GPS ride tracking with route, distance, moving time, average speed and elevation. Each ride is saved on your phone first, so you can compare your rides over time.
Example data from the ride details.
The motor decides what Trolda can read. Type your bike the way you know it, and we will find the system.
More motor systems are added continuously.
Without a supported motor, Trolda still records your ride with GPS.
02 Battery & history · Know your bike
Track available battery and motor data over time. Build a history you can share when it’s time to sell your bike. What is available depends on the motor system.
Selling a used e-bike? Create a condition report with the information available about the bike, motor and battery, plus the history recorded in Trolda: odometer, battery health, charge cycles and motor operating time when the bike shares them. The buyer opens the link without an account, and every figure shows where it comes from.
Available information varies by bike. The report does not replace a physical inspection.
Battery health, charge cycles and consumption per kilometre, when your system shares them. Trolda reads them again on every ride, so your battery history grows with the bike.
Diagnostic data from the motor, such as torque and operating hours, and a clear view of what your bike does not send.
Illustrative app view. All figures are sample data.
Download Trolda03 Community · Ride together
Connect with friends, join groups, explore segments and compare your rides, also with riders on other supported motor systems.
Riders with different supported motor systems can share a group. Each bike measures rider power with its own system, so figures from different motors are not standardised.
Download TroldaGet Trolda for iPhone or Android. The download button takes you to the right place for your phone.
Switch the bike on and pick it in the app. Without Bluetooth, skip this step.
Tap Start ride. When you get home, the route and the numbers are ready.
Trolda and the condition report are free during the launch period, with no subscription. If that changes, prices will be shown here before they apply to you.
Trolda then records speed, distance, time and elevation with GPS, and you can keep a maintenance log. Watts and battery from the motor arrive once your system is supported.
It brings together available bike information and shows its source. It distinguishes readings, calculated values and information from the owner. The report is not a workshop inspection or a guarantee of the bike’s mechanical condition.
Ride recording is saved on your phone and can continue without mobile coverage. Syncing and sharing reports require an internet connection. Offline recording does not mean every online feature works without a connection.
Rides are stored on your phone, with a cloud backup if you have an account. Friends only see rides you share, and on a shared map the start and end are cut off.
No. The report link opens in a browser without an account or installation. It lasts for 30 days. The person who created the report can revoke it sooner.
