    • Fun to be had on this yellow bike
Color: Yellow Size: 17"
I bought this bike for my girlfriend and she Loves It. It shifts easily with the thumb shifters, and the shifters have indicators that let her know what gear she's in. The mechanical disc brakes are a little noisy but work fine, and seem to be better than cantilever or caliper brakes on wet conditions. The bike arrived mostly assembled and in good shape, and assembly was pretty easy and straightforward. The gears shifted alright out-of-the-box but needed to be tuned first, and the brakes were already adjusted and ready to go. We needed to adjust the spring shock since she is small, and the ride was a little bit rough for her light weight before the adjustment was made. The fork shocks don't seem to be adjustable, but they work fine as-is. Trail riding is fun on this bike, the shocks really soak up the bumps on rough terrain, and the rear shock keeps the back tire on the ground when going up a hill with loose gravel on it. Plenty of gears keep a rider up with the rest of the pack, as well as offer plenty of power when going over hills and rough terrain. The lightweight aluminum frame makes it easy to take it on and off the bike rack, and is light enough for my girlfriend to control and sling it around on complex rides. It's just an overall fun bike to ride. ... show more

    • Terrific Value
Color: Black Size: 21"
Excellent entry level mountain bike. I am an experienced mountain biker coming back from a 5 year layoff due to injury. Gave away all my bikes so I needed something inexpensive to see if I was going to be able to ride again sustainably. This bike has all the components of a bike costing thousands more - it’s just 10 to 15 lbs heavier because it doesn’t utilize state of the art materials such as carbon fiber, titanium or high strength aluminum. Great disk brakes and 24 speed shift set and good full suspension ride. Comes well packaged for shipping and is very easy to complete final assembly for the average do-it-yourself person. Excellent choice for any biker on a budget. ... show more

    • Great
Color: Yellow Size: 19"
Its a great bike that looks awesome and handles rough terrain like a champ. Putting it together was easy, and keep in mind that you may need to do some adjusting on the breaks as they may need it if the disk is touching the caliper.

    • Hard to put together, but seems like a decent bike
Color: Yellow Size: 19"
Edit: the extra j-shaped part is a sacrificial part that is meant to be destroyed in case of an accident to protect the rest of the bike, which is why they provided an extra one. Original review: The instructions that come with the bike are total garbage. It pretty much just tells you to take the bike to a shop, go slow, ask questions, use grease (I didn't), and use muscle (what?). There are no step by step instructions and no tools provided. I'm pretty handy and did eventually get it working well. Getting the handlebars, seat, front disk brakes, and front wheel "on" is pretty self explanatory, however pretty much nothing was lined up correctly (even stuff installed at the factory). If you don't have that front brake lined up perfectly, it sounds aweful when riding and it's pretty finicky about placement. I also had to adjust the back brake position. The derailleurs needed to be tuned (thanks internet) so that it would shift properly and quietly, but it's pretty quiet now. In the end, I still have an extra piece. It's a J-shaped piece of metal with some holes in it. There's already an identical piece like this installed on the back of the bike and it does not fit on the front. The bike seems to work fine without it, so maybe it's a random spare? It seems like a sturdy part that wouldn't likely ever break, so I'm not sure why a spare would be needed when they don't provide spares of anything else. Makes me worried something important is missing and the bike is going to fall apart on me, but it seems to work ok. (Edit: after some research, this part is called a derailleur hanger which is designed to be damaged in an accident to save other parts, hence the spare). Again, actual assembly instructions would be very helpful. A signature was required so USPS double-rang my doorbell and woke my toddler from his nap, which is annoying since this is a pretty cheap bike and I've had much more expensive things delivered with no signature required. I think my least favorite thing about the bike is that I don't see how you could ever attach a kick stand to it with the way the back is designed. So I'll have to lay it down or lean it against something. Overall, this seems like a good bike for the money. Putting it together was a pain, and honestly if I could rewind time, I would just spend a little more and go to a bike shop or even a sporting goods store to get a bike that's already put together and tuned properly. My 2 year-old kid was going nuts while I was putting it together and couldn't wait to go for a ride with dad, and kept trying to "help," which was cute, but...not actually helpful. I'd rather just have pulled a new bike out of my trunk, thrown his seat and handle bar attachments on and taken him for a ride. If you're on a budget, though, and don't mind tinkering and watching a YouTube video to compensate for the lack of provided instructions, and don't want a kick stand, this is a decent purchase. ... show more

I live on a the small island of San Pedro Belize. I could not be more pleased with this bike and have been a road cyclist in my younger days with bikes coaster over the 3k price range. I have rigged it up with fishing pole holder, fenders( all dirt/ mud roads) and some other small mods. I’ve putover 3,000 miles on it since April. For the price point this bike is FANTASTIC! Easy assembly and I have yet to have an issue. Durable, awesome look and I can beat the golf carts on the island. Kudos to GRAVITY BIKES ... show more

    • Great bike! Well worth the cost.
Great bike! I'll start with more general info and then move into the details. I got the small 17 inch bike in yellow. Ordering was easy with no hassle. I live in New Mexico and the bike shipped from Dallas, so it took only 3 business days for it to arrive. It arrived in a large box, about 80% assembled. Assembly does not require a professional, but involves installing the front brake, front wheel, handlebars (just make sure they're tight), and the saddle. The tires come pretty low on air, and should be replaced, because they go flat within an hour of riding. Suspension: front suspension is great. Easily adjustable, great shock absorption when downhilling. Rear shock is a bit slow but is just fine on jumps. Brakes: mechanical disk brakes provide great stopping power, nice and quiet. ... show more
