A downloaded route can guide a ride without giving you a way around an unexpected closure. Before heading out of service, check the route on the device you will actually carry. Seeing a download badge is not the same as opening navigation with no connection.
Open the Route With Data Off
While online, finish the download and reopen the route so any pending synchronization can complete. Then, while safely stationary, temporarily turn off mobile data and Wi-Fi and open it again. Try starting navigation, rather than just viewing the route's name in a saved list.
Check that the intended start and destination appear, the route line loads, and no warning blocks navigation. If you are at the starting location, check that the displayed position corresponds to where you are. A map centered on the starting pin does not by itself prove the app has located you.
If the position is unavailable, check the app's location permission and its own troubleshooting instructions before departure. Restore your connections after the check. A test at home can reveal missing downloads; it cannot prove reception or map accuracy everywhere along the ride.
Check Beyond the Route Line
Komoot separates downloaded routes from regional maps. Its current offline guidance allows following a downloaded planned route, but automatic rerouting needs an internet connection. If you leave the route offline, it can continue showing the original route without calculating a new way around the problem.
Downloading a wider region does not remove that rerouting limit. It helps you see more of the surroundings. Pan over the return area and your planned alternative while offline: can you read the roads and junctions you would need, or does the useful detail disappear?
Other navigation tools can behave differently, so check the one you use. For longer rides on electric bikes, include the navigation device in your departure check: the phone or computer mounted on the bike needs the usable download, not just the device on which you planned the ride.
Decide What a Closure Would Mean
Imagine a gate across the planned route with no data connection. A visible road beyond it is not enough: you need a known, permitted connection around the closure, not merely a line that looks nearby.
Use a previously checked alternative, or retrace the route only where that is safe and allowed. If neither provides a continuous known exit, stop exploring and use your contact plan when communication is available. Do not follow an unknown shortcut just to chase a signal.
The route-risk checklist helps choose that backup before the ride. For the offline check itself, be able to say: the route opens, navigation starts, my position is identifiable, the needed surrounding map is readable, and I know what to do if rerouting is unavailable. A missing item is something to resolve before leaving dependable service.
