GMC Denali and you
Nice bike. I purchased this bike primarily to get to work this summer, iv had GMC Denali for 2 months and i managed to put 360 miles on it over the summer. It’s a very good looking bike, and it can definitely pass for a bike that cost 3x as much. I really enjoyed having this bike, however, there were a few disappointments.
After the 1st week, the tape on the steering wheel began to come off, later the shifters began to malfunction, the shifters are the ones where you have to turn up and down, not like the more expensive bikes where the shifter is made into the brakes. In addition to the shifter problems. when you want to go to higher gears you have to twist that cheap nob really hard so when you do that it feels like its going to break off.
Furthermore, the front derailleur would scratch against the chain making an annoying sound and damaging the chain at the same time. I spent 15 dollars on a tune up, which didn’t fix the derailleur problem.
And finally, this is the reason to why i had to return this item, my front wheel could no longer hold air and the wheel itself cracked a little after i bumped into a peace of contrite sticking out on the road.
Crap shoot. Look, the bike is great for the price. But if you’re looking for something awesome, spend the extra couple of hundred bucks and get a real road bike.
This bike is doomed to a number of problems. The brakes aren’t great, the shifters don’t work well in the higher gears, and overall it’s… a crap shoot.
I’ve already had to replace two tires. Whether that’s because of the city road conditions or crappy tires is up to you. 
Great bike!!! Great Price!. 1st- amazon.com has their stuff together! Bought the bike on may 17th and it was at my door on may 19th!! No Joke.
Ok on to the bike itself… For the price this bike is truly unbeatable. Shifts great, is of decent weight, comfortable and looks amazing. Only downfall is that the brake pads that come on the bike are a little hard, which makes for tough stopping, but if you go to a bike shop, they can help you out for about 10-15 bucks.
If there were ten stars to give, I would give this bike all ten!
