Before you start
Good to know.
Will Trolda work with my e-bike?
Check the motor systems listed above. Bosch support covers the Smart System. The bike brand alone does not identify the motor system. Available readings and report information vary between systems.
Do I need mobile coverage on my ride?
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.
What does the condition report tell me?
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.
Does the buyer need Trolda?
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.
How much does Trolda cost?
Trolda and the condition report are free during the current testing phase. Launch pricing will be shown here before you start using the service.
When can I download the app?
Trolda is being tested on iPhone and Android before public launch. App Store and Google Play links will appear here when the app is available.
