“A good road bike for beginner or commuter”
I wanted switch from mountain bike to road bike. So I searched on craiglist for used road bike, however the rusted used bike is so exensive. Then I found this GMC denali in the web. It's new but the price is cheaper than used bikes on craigslist. After more than 4 months ride, the bike seems strong and good quality. I ride the bike almost everyday. And people were amazed when I told them the real price. The bike looks very nice with yellow color. In order to ride it, you height needs 6 ft because the bike is large. I can get maximum speed at 38MPH downslope while 25MPH for flat road and 17-20MPH for cruise. Rides very light and smooth.
The only con is when I assembled from the box,the gear needs adjustment otherwise some gears were not engaged. If you can do it by youself by watching youtube like I did, the it's not a problem at all.
