I used two different bikes, both of them had a 10km or more autonomy and suddenly stopped after a few meters. I took one this bikes to catch a train, it was too long walking but perfect cycling having a bit of extra time and still I missed that train. I am really disappointed by this bikes, the idea is really nice but there is a lot to improve.

Terrible. Impossible to log in my driver's license for some reason, the app just doesn't function. The first time I used it then it took 12 minutes to end the ride because the app just kept going back and wouldn't let me press the "end the ride" button. The second time as well, then the app failed and wouldn't open for 10 minutes. I spended more time trying to end my rides than I actually did using them. And I've got other bad opinions from friends about it, should've listened to them.

The app is always buggy when you needed the most. Unable to ride after booking the bike multiple times. When you pressed start, you'll automatically get charged. Regardless if you're able to ride them. When you cancel right away, you'll still get charged, even though you end up didnt ride the bike. Less than two weeks and at least three failed attempts already. Lastly and most frustatingly, there's no refund button for this failed attempt. Just install other competitor apps.
