SEVICI ٤+

When choosing the subscription, choose the ~€3 euro one for a 24h ride. This will allow you to rent the bike for 24h only to use in 30 min chunks or else you’ll get charged €1 per extra 30 min.
Plan your route and make sure you’re always a few min away from your next stop (extra tip: look if there’s parking for your bike) it usually says 8/10 so there’s 2 parking spots left, I found a few that were full and I had to search for a further one that made my trip longer than 30 min therefore I got charged.
Otherwise, it’s super simple to use, park and rent. Make sure that you check your parking is completed. You can check on “my journeys” if it matches your end time.

It’s a nice app but it has lack of user friendly. You can skip the ID, but itsn’t mentioned anywhere. The rides could be sorted from low to high prices because tourists usually don’t need more than 1 day. The subscription process it not clear.

The app and service is completely and utterly worthless. You have to make an account and it asks for an “ID number”. It doesn’t say what kind of ID. Drivers license? Learners permit? Passport? Doesn’t say. It doesn’t offer any troubleshooting. No matter what number you put it, it will say it is wrong, so you can’t create an account. Reviews from December of last year give the same issue and the app is never updated. Go rent a bike from a store while in Seville. These bikes are basically sitting on the street for show.
