For all those who are considering buying a RM maybe can find helpful my experience. I own a RM Powerplay 2019. A couple of months ago the bike didn't switch on, so I did a couple of checks and remote controler was working and batery look fine. So I went to my LBS and did a couple of more testing...
I live in Barcelona area although I always ride Pyrenees trails. In Collserola mountain (known as Tibidabo as well) there is plenty of trails. Here you can find some rides.
The good point is that you don't need to rent a car from Barcelona, you can take the metro up to Vallvidrera...
