    • SOOO worth it - torture testing the Impasse
I bought this bike off amazon for $250. I have been a downhill racer for 17 years so I feel pretty confident when saying I know what I'm talking about. My downhill bike is a Cannondale Super V Carbon 700 Missy Signature Edition with aftermarket goodies. I bought this bike for just something to play with. However, I was pleasantly surprised at what it can do. I can't say much about the packaging because, there is NO packaging. It's literally a bike in a box, so expect some sort of damage. Unless you do the work yourself, don't plan on taking it out the day you get it. I do some very serious mountain biking on single track trails on this thing all day once a week at Jiminy Peak, MA. Have been out 6 times now. The terain is very steep, technical, and rugged. Full face and gear required. The 29" wheels are a bonus. The bike handles very well. The pedals are metal and nice and grippy. The ride is pretty nice. The rear shock is actually pretty decent. The fork is a little soft. I bottom it out all the time. I can't say much about the shifting and components cause it's downhill. I never really shift. As long as I have 8th or 9th gear I'm all good. The bike can really take a beating too. I've spilled it probably a dozen times. I bent the handle bar which I just hammered back in place. I also broke the crappy plastic chain ring guard. That's pretty much it other than the expected scratches and cosmetic damage. No damage to the wheels or hubs, the suspension is fine, and the seat has not one tear. All shifting and brake cables are all good. I do tune the shifting and brakes after every run. It's just cable discs but oh well. I am on my second set of brake pads, as they are very small and not made for this, and my second rear tire, but the bike is still 100% factory. Anyone who says this bike is only good for the driveway or riding to work is seriously underestimating it. It will never stack up to my Super V, but when considering what I get for the cost ($4K less than my Super V), this easily gets 5 stars from me. Tough, cheap, and it gets the job done. **UPDATE** So I've had this bike for some time now and it has continued to impress me. So I increased the amount of times I ride it from once a week to twice a week. I have no problem keeping up with my buddies on expert rated downhill courses. They all have different downhill bikes such as my Super V that all have a camma in the price tag. Pads and tires are literally the only thing I've had to replace so far on this bike. The parts are cheap, and I order them right from Mongoose so the bike stays 100% factory. This bike has taken a beating and some pretty hard hits, and I have no damage other than the expected scrapes on the frame and handle bars. My buddies have actually nicknamed the bike "the death wish" lol. They say I must have one for riding a bike the way I do with them that you can get for $250 at your local Walmart. However, with what it's been through so far, I don't see it going anywhere any time soon. I inspect the entire bike before and after going out for the day, and I have not found anything wrong. I have removed all of the front shifting components. I just don't need them and they were just getting in the way. It's not that there was anything wrong with them. Also a couple tips if you do some serious riding with this bike: Check the hubs before and after you go out. Especially the front. They have a tendancy to loosen up. Also you may have to lube the fork every now and then or it will become rigid and stiff. Other than that, I say purchase and enjoy. ... show more

    • Great Moountain Bike !
This is a great bike for the price. It came mostly already assembled which was a nice surprise. I saved alot of money assembling the rest myself. I am a rough rider so I have already bent and damaged the derailleur which I think should have been better designed. This is a great bike to build on and tweak yourself. It really goes over all the bumps and does what other bikes can not do. I am very impressed with this bike. It is a very fast bike and I have had a tone of fun riding it. I wish the seat was a bit taller and the crank shafts a bit longer as I am 6'3" and around 230 pounds. You really can't beat the price. A similar bike that is swift and has a full suspension like this goes for around $700-$800 so I feel like I got a great deal. I saved on not having it assembled and that was a huge plus. Really the only downside was that its made in China so everything is delicate and the quality of the metal is not as good as it should be. Mongoose has always made the best bikes in my opinion and its just wonderful that they offer a full suspension 29er at this price. The bike is delicate and its noticeable how things made in China are done with the minimal amount of material in order to save money so things on this bike bend and break easily when you really bang it through trails like I do. I suppose it would be fine if you ride on the streets mostly. I just wish it was built stronger and built to last longer without needed frequent maintenance and repairs. I understand how the manual recommends frequent preventative maintenance but I just don't have the time to do all that and I ride really hard. If I could have afforded a really expensive bike I would have still chosen a Mongoose. I plan on adding to this bike so its more durable and can take the abuse I give it when I ride it in the woods and up and down mountains. I like to go over rocks with it. I will be a loyal customer of Mongoose for life. The feel of a real Mongoose once you get to riding is unlike any other bike. You just can't find a great bike like this for a better price. ... show more
