Customer Reviews

When I opened it, the frame was pretty badly scratched.
Its a perfect size for my frame (6' 1" and 180 lbs) and can tackle hills, roads, etc.
David Martel
It was easy to assemble for someone handy with a few tools.

I bought the Mongoose Impasse because it fit my budget for a full suspension 29'er mountain bike. I felt the bike was a bit of a gamble, because detail specs and reviews are just not available. But I was feeling adventurous and ordered one.

First, the bike was rather poorly packed in the Mongoose factory box. No Styrofoam packing was in the box to protect delicate pieces like the rear derailleur, or the wheel hubs. The bike came partially assembled with the front wheel tie wrapped to the frame. Just a little bubble wrap, and a few plastic protectors for the hubs that were broken and laying in the bottom of the box. As a result, the rear derailleur and mounting point were badly bent in shipping by Fed Ex. So I removed the derailleur, straightened it out, and also straightened the mounting point (near the axle drop outs). Took about an hour to get the parts back in proper alignment.

Second, the Owners Manual covers ALL Mongoose "department store" bikes, so be patient to find the section specific to the feature on your model (aka Threadless stem vs classic Quill Stem adjustment). I would have liked a shorter owners manual with more info specific to this model.

After assembly (which is not really difficult assuming there are no damaged parts), be prepared to adjust the disk brakes. They should not drag, and are easy to adjust if you follow the manual. Just be sure to spin the wheels and ensure that the disk is centered in the caliper. I also had to spend a little time making adjustments to the rear derailleur to make it shift properly (although this was probably a result of the shipping damage). If you are unsure about being able to do this sort of work, just take it to a local bike shop and they will set it up properly for you.

Now the riding.

I'm: Height 5'7", weight 154 pounds
I Use it for: commute to work around 10 miles each day, 3 or 4 times a week,
My previous bike: 26" no suspension, steel frame, very heavy no aluminum parts.

Packing: Ok, NO broken parts.
First adjustments: brakes.
Wheels: Ok, but they begun to loosing pressure after 2 weeks of use.
Paint and stickers: regular quality.
Suspension: front and rear are low quality but for soft use are Ok.
Seat: looks nice but too cheap. It was tore with the first 4 miles.
Doesn't work for me: seat tube is too short and I must buy other one and the seat is not confortable at all.
Frame: great.

General: The biker is nice but have some low quality parts, that justify the price. Check out there are a sticker that said "This Bicycle is not designed for competition, stunting jumping or off-road use...."

Driving: Since this is a 29", you're going to apply more force to go on, this could be discourage. Beside that I have increase my Max speed from 24mph to 31mph, Avg speed from 15mph to 18mph. Of course it depends of the route.

Beginners don't buy this bike, try for 26" and cheap one, after you turn in an amateur cyclists you will be ready to try it, and feel the difference.
Amateurs and occasional riders try it.
Semipro and pro don't waste your time with this bike.

I just recieved my new Mongoose Impasse 29" mountain bike.

I haven't riden it yet due to illnes but I'm anxious. It was easy to assemble for someone handy with a few tools. It required a metric wrench, metric hex "allen" wrench and a screwdriver.

There was no recomended rider height for this bike so I took a chance. If your jeans are over 32" long you'll be OK, I'm a little short but I'm keeping it. All the faux componants are there for a $1000+ bike and they look good.

I'm a little sensitive to false advertising so when I noticed the "ALUMINUM MONGOOSE" sticker attached to the "STEEL" rear suspension fork it set off my BS detector. The front fork is also steel which might be understandable for strength. The steel kickstand should have been aluminum even though it's not part of the frame. The seatpost,rims, stem and handlebars are aluminum. Overall my bike and I could stand to loose a few pounds but we'll work on that together. One of the plastic brake lever adjusting screw holes is striped out and I'm in the process of trying to get them to send me a replacement. So far no responce. I'm not sending the bike back for a minor defect.

I'll let you know how it works as soon as I get back on the road.


After a few miles on the Mongoose Impasse I'm satisfied with the value. Everything works as advertised.It has a very soft smooth ride and at the same time it feels tight and responsive. My previous suspension bike had a tendancy to bounce and jiggle around a little. This one just absorbs the bump and dosen't oscillate. I didn't even try the seat it came with. I bought a split gel padded one while I was waiting for shipping. Customer service at Mongoose was very good to deal with.

I went from an old entry-level GT (Aggressor 2.0) with aluminum hard tail frame, caliper brakes, etc. Gears were getting worn. This was on sale around Black Friday so I sprung for it rather than having a new gear set installed. WOOPSE!

The old bike has a LOT of mileage and a LOT of thrashing on it. Warp in the front wheel, bull bars, scratches, dirt, everything is worn. Last couple of years I've primarily just used it for taking the kids for rides in a trailer. But it's an old trooper.

This Mongoose is just an embarrassment to itself. Let me enumerate the unfortunately lengthy list of things that are wrong right out of the box, and some inherent design flaws:

1. One of the tire tubes (rear, as it turns out) was leaky from new. A 3-mile ride and the tire is down when I pumped it up just before I left. (Fixable, but should not be the case.)
2. The front brake caliper's inner brake pad rubs against the rotor when the axle is properly seated in the fork. (Fixable, but should not be the case.) (Update: Adjusted the inner brake pad, cable tension, but it appears the front rotor is warped as well, it squeals in cycle with the front wheel rotation while riding.)
3. The crank shaft squeaks and creaks, sounds like dry or just bad bearings.
4. The derailleur is either mismatched or improperly adjusted; the chain derailed three times during my inaugural ride. (Update: further riding indicates that the gears just don't shift quickly/smoothly relative to better sets. Adjusting cable tension helped only incrementally but still could no solidly land a gear, especially when moving across several sprockets quickly.)
