GMC Denali Road Bike

This is the first time I've ever returned an item I bought from Amazon, and I've bought a lot of junk in my time. Like most of the other reviewers, I was drawn to this bike by its low price and mostly positive reviews. I didn't want to spend too much because I already gave up my spring break so I could work to be able to afford a new bike. I also didn't want to spend to much because I graduate in a little over a year and don't know where my job search will take me and don't plan on moving very much stuff. It all seemed perfect. Then came the assembly.The tires that came with my bike were too big. The front wheel was in contact with the frame when it was straight on. I didn't even get around to inflating the tire and it was already rubbing against it! If I turned the wheel it would come in contact with the pedals, unless they were specifically out of the way. I couldn't even test ride the bike because it wasn't possible. But everything did seem to be pretty low quality. I also have no idea why they positioned the brake levers where they did, I've never seen a worse spot for them.Thankfully I am like a kid at Christmas every time I get something from Amazon so I was able to realize what a blunder of a purchase this was while I could still return it, because Amazon's window is really short for this item. Also thankfully I will be home all day tomorrow to wait for the UPS guy to come back and pick this piece of junk back up.I really need a bike to get to work so it's back to the drawing board.Some people seem to have no problems with this bike and love it, but I feel it is my duty to give it a one star to show it isn't necessarily all gravy. I know I'm not willing to risk a replacement being as terrible and I'll just take my money back and look for something better. May mean a bit more money but I need something that will actually work.The question is, are you feeling lucky punk?

I have only owned this bike a month and have put a little over 400 miles on it. It has already had numerous problems so you do get what you pay for. I would only recommend buying this bike if you don't mind putting in some work or for whatever reason you don't want to spend any more. It will still get you around for atleast a little while. After only about 100 miles, the bottom bracket started grinding like crazy. I ended up taking it apart and found the bearing cage in the fixed cup to be in very rough shape. The fixed cup also appears to have numerous miniscule cracks. The bottom bracket used on this bike is normally only found on bikes from the 70's and 80's(adjustable cup). I ended up replacing it with a 122.5mm Shimano UN55 BB Square Taper Bottom Bracket. I'm not an expert and I haven't had time to test it out but it appears to be the right fit. After 200 miles the rear started grinding pretty badly. The hubs used on this bike are of very low quality(pressed-steel). I used Park Tool FR-7 Freewheel Remover for Falcon Brand to remove the freewheel and found one of the cups that contain the bearings(which I believe should be welded on) was completely loose from the rest of the hub. This causes the wheel to wobble a significant amount and makes adjusting the bearings much more difficult. I plan to epoxy it back together to get a little more life out of it. I have also replaced the handlebars with a Avenir 200 Series Rise Mountain Handlebars, Black, 640mm wide because the narrow drop bars with shifters far from the brakes just didn't work for me. This also required new brake levers/cables and grips.I also recommend finding some new pedals because the metal on the ones it comes with are very sharp and cut my legs up a couple of times before I changed them.Some details people may wish to know:The bottom bracket is standard 68mm english thread with adjustable cup similar to Pyramid Bottom Bracket Cup Set 1.37 x 24 English but with a 36mm fixed cup instead of what looks like 16mmThe rear fork according to my measurements is close to 135mm spacing which is the spacing for mountain bikes and not road bikes.The freewheel on mine was produced by Sunway Group Co. and a freewheel tool for Falcon Brand freewheels was able to get it off.The handlebar stem seems to accept 31.8mm handlebars well.The drop bars are two pieces of steel tube bolted together to allow the twist shifters to slide on from the middle. A set of aluminum plates then adapts them to the 31.8mm stem.
