There are quite a few games like this now, downhill bike racers. I play them all for a few hours and really enjoy the tactile sensation of riding the bike and the lovely tracks and scenery, then I quickly hit a skill wall where i find it impossible to do the tricks the game requires. Too old or never had the motor skills to begin with. I cannot do most of the tricks here to save my life and the game doesn't even tell you how do to a lot of them. Every one of these games is like that. I wish there was one I could play and enjoy cause for a little while they're very nice!
Also the second level of this one on the career run is just non-stop haze all the way through the biome (forest) making it completely impossible for me to even just run down the track. I've been loudly anti-haze in games and continue to be, its a shitty lazy ugly mechanic, stop putting haze on everything!
