I bought my g/f a weekend (short trip for breakfast and ride around the neighborhood) bike ... very similar in parts / construction to the denali, however her bike is a schwinn varsity ... (it actually has presta valves !! ) ...
This thing has no more than 100 miles on it and the hoods are already cracked and falling off... lol
The innertube on the rear tire exploded the moment i pressurized it... I had to replace both innertubes just as a precaution the next day ...
ohh well, you get what you pay for... I don't regret paying $ 200 for the schwinn, after the tube overhaul, it seems to be working ok for her once-a-month 15 mile ride.
