It's alright. At its core it's clearly meant to be a sort of zen game where you just relax and take in the sights/sounds while riding the bike, and I appreciate that about it. It's definitely my favorite part of the game. That said, my biggest issues come when attempting to complete the various challenges, which are required to unlock mountains, trails, bikes, etc. Once there were actual stakes such as completing trails within a certain amount of time or with a limited number of crashes allowed, there were so many small annoyances that really added up and bothered me while playing, primarily how janky the bike controls sometimes and how easy it is to crash.
