I am a little ashamed to say that my brother did the bike tour on a GMC Denali. He has almost 200 miles on it and it is still running well. Of course it isn't as smooth as my
Specialized Transition Multi-Sport. The shifting and brakes are rough on the Walmart bike, and of course it's quite heavy. I also did see a black GMC Denali on the ferry and I was surprised that some one else had a Walmart Bike.
