Completely agree.
I was actually expecting an experience similar to Mario Kart DS since I was expecting the Wii Wheel to be a piece of crap. Luckily I was completely wrong. The Wii Wheel is awesome and the levels are just plain incredible. The bikes aren't as nearly gimmicky as I thought they would be and the game is just genuinely brilliant. Even the online works great (though I'm not that good yet, I keep getting beat >_<).
I love this game.
