    • So glad I bought his bike
Style: Trail Size: Large Color: Neon Green
Review Image by TexasLadyPirate TexasLadyPirate
Bike was very easy to assemble no parts missing. No parts damaged in shipping. Bike had no scratches in it and welds and paint job is very well done. Extremely happy with my purchase and the speed if shipping. Did have to Oder a kickstand and replaced the skinny seat with one more comfortable (wider). Bike shifts easy and is a very smooth ride. Came in Bright Bright Lime green green sticker states neon colors may fade, this is odd does this mean if I leave it in the sun or no matter what? If so they need to use better paint as the color is really cool! Bought the large frame as I’ve had a hip and knee replacement and don’t bend as much as I’d like. The height and size of the bike are perfect for me with my limitations and my 5’11” frame. Bike is not heavy which is great as hubby can’t always be around to help me load it fir out of town trips. Frame and handle bars are thicker than standard bikes so read any accessories you buy to make sure they fit. This is a bike for off and on road riders. Like the wide tires as I live in the country and sometimes need to avoid traffic (weedy shoulders). Great bike for both men and women regardless of age. I’m in my late (late) 50s but my kids already want to borrow my bike (no). Great bike, highly recommend, great brand, I expect many years of use out of this bike!! ... show more

    • What a Pleasant Surprise
Style: Comp Size: Medium Color: Grey
I read an article recently that said Mongoose had started building good bikes again. I was skeptical, but I needed a decent hardtail for my wife and really didn’t want to spend $1,200. And even if I did, they were all sold out anyway, so I bought her the Mongoose Switchback Comp for $600. Tonight I opened the box, put the frame on my stand and settled in for what I thought was going to be a nightmare assembly. Not 45 minutes later, I was done! Other than having to tweak the brake cables just a touch, it went together like a dream. The derailleurs were pre-adjusted perfectly and even the seat angle was dead on. There was even lubricant where it was supposed to be and the screws for stuff like the handlebars already had Loctite on them. I was also impressed with the components. Everything that mattered was from Shimano and other reputable companies and they were all decent grade stuff! I do wish it had Presta instead of Schrader valves, if only because now I need to keep 27.5 tubes in both styles, but it’s a minor thing. As for the construction, it was also impressive, especially at this price point. The Aluminum frame welds were as good as I’ve seen and where the cables were run through the frame, the holes had reinforcing plates welded on. I found no rough or sharp edges to cut cables or snag clothes. It’s also a very nice looking ride in dark gray matte with pink lettering and the finish is nicely done. The devil is always in the details and this time, the folks at Mongoose really got it right. I recommend this bike and wouldn’t hesitate to to ride it straight into the nasty stuff! ... show more

    • I think the size runs a little small
Style: Expert Size: Large Color: Grey
Great bike, although I did receive it with 1 flat tire. I contacted mongoose and sent me a new innertube. The derailer does need to be adjusted. Also I feel a little big for the bike and it seems like the size description isn't right but I'll end up keeping it because i do like it.but other than that is was easy to put together. I feel like this bike is to expensive for what it is. I looked at some trek marlin models in the same price range and they have better components. ... show more

    • Nice Bike W/ Decent Components
Style: Sport Size: Medium Color: Navy
I was skeptical about ordering this bike considering some of the lousy reviews it's received on Amazon. But, when I looked at most of the negative reviews, they were more about the shipping than the actual bike itself. IF your Mongoose Switchback arrives in a totally intact cardboard box (which mine did), what you'll find inside is a well-outfitted bike for the price. First you'll notice the attractive matte paint on the (somewhat heavy, but not unwieldy) aluminum frame with internal cables. Shimano shifters, cassette, cogs, crank, and DISC brakes run smooth. Hybrid Kendals tires on Xposure aluminum rims are perfect for different surfaces. Xposure front shock is a bit soft, but is ample as long as you're under 200lbs. Grips, seat, and handlebars feel firm. The only knocks I have on this bike after riding it for a few hours over one week is the cheesy feel of the plastic shifters and I question how well the crank arms and pedals would perform taking it downhill. But, as an everyday bike where it's not going to get much off road abuse, it's a great bike and fun to ride. ... show more

    • Great Bike!
Style: Sport Size: Small Color: Orange
Review Image by Irving G Irving G
I love this bike! It rides great and is a very sweet looking bike all for a very affordable price. The bike arrived mostly assembled needing the seat and post, handlebars, forks and front wheel to be assembled on to the bike. It is something that can be easily done if you have even the slightest inkling of mechanical inclination. There were some minor adjustments I needed to make mostly to the brakes, other than that everything ran just fine on the initial test ride. A few of the things I was very impressed are how light the bike is for a mountain bike with a front suspension, I'd say it comes in at under 34 lbs., I was extremely happy at the color scheme on the bike, which I was a little apprehensive on whether or not the picture online was going to be a good semblance of the actual unit and how smooth and sturdy the ride is. Very pleased, and do recommend for a bike at the $500-$600 price point. ... show more
