Can’t say enough bad things about this bike.. I ride about 5 miles a day from home to school and back. Very flat, good weather, easy ride, and I’m not huge or anything. I figured a cheap bike like this would last a year, and then I’d upgrade. I’ve had Mongoose Montana Mens Mountain Bike a month, and there have been a number of problems.

In general, the parts are flimsy. The seat post clamp won’t prop up the seat. The handlebars are loose because the bolt that holds them comes loose. The bike feels like it’s off balance. Also, while making sharp turns, my toes scrape the front tire. Biggest problem – pedals made of really weak plastic that actually ripped. Drivetrain, shifters, and brakes OK so far, but I’m not expecting much.

Do NOT buy this bike if you expect to ride it on a daily basis. Spend 2X or 3X more and get better quality components.

You Get What You Paid For. Sometimes being frugal about certain items is not worth in the long run. Take this bike as an example. Took it out of the box and, at first, looks very promising. After placing all the parts together (handle bar, front tire and seat) took it for its first spin. First thing I noticed that it wasn’t shifting (rear) correctly. Brake pads (front and back) need adjustments to make them not rub against the rims. Took it back home right away and discovered that the rear derailleur is bent – signs of poor/very cheap quality. With my bare hands, straigthened the rear component and took it for a spin again and after adjusting the brakes. I got the rear gear to the highest number but couldn’t make it go to the lowest number – more adjustments. Despite being Shimano components, I was very disappointed of the low quality parts. So just expect to make quite a few adjustments with this bike. If you are not mechanically inclined, try asking your friends or make some new ones who are, otherwise, to the bike shop it goes.$$$

Not the best, but good warranty.

Ok, I must say that I am totally disappointed with this product. First of all, I had to reassembly front brakes, because they were not working properly. Then, I realized that spokes on the front and rear wheels must be adjusted as they were wobbly! Luckily, I knew how to do that, but took me about 1 hours to make it work and to true the wheels. Then, tried to ride it; guess what! the gears needed adjustment! I also did that, and thought that it is now OK. I use the bike to commute, 10 miles a day. I rode it like 70 miles (on the main road) and the left pedal is now broken! I am 165 lbs, and I am not riding aggressively.The pedals are really bad quality!

I also had problems with the handlebars. Couple of times they became loose during the ride, and I had to stop and fix it. I am really lucky for that didn’t cause an accident!

Make yourself a favor, instead of buying this bike [...] for all the adjustments, pay more and get something better than this!

I know that it’s cheap, but it is not free! And cheap doesn’t mean that exaggerated low quality product! I would definitely return it If I could!

Edit: I think I have now problems with the fork: the slider moves back and forth, even though the stanchion is stationary (I am not talking about the normal up-down movement of the suspension!). I hope it will not fall apart when riding!
