My 7 year old boy loves it. I'm impressed with quality. Don't hesitate to buy. Now he can keep up on our longer rides and doesn't mind the hills as much. Great way to get them into the sport at a reasonable price.

My 7 year old got this for his birthday. He is 48.5" tall and weighs 48 lbs. The gears on this one are much easier to shift than the 2013 model I saw in a local store. He is having to get used to a "real" bike with hand brakes and no back pedal brakes but that will come with time. It's a great size for him now and to grow into. Amazon was great with delivery, as always. We will likely be buying the 24" version of this for my other son this year and the 20" girl version as well. Lighter weight than the ones we looked at at Target which was great. My son wanted a "real" mountain bike with gears which is somewhat difficult to find in a 20" that is well made but doesn't cost a fortune. We love this bike!

My Qualifications: I don't work at a bike shop, but I can fix anything that is wrong with a bike. I have stripped down an old Trek 4300 and replaced pretty much everything.

I have spent about a week with the bike. It seems like a solid bike so far.
Parts I like: Shimano RivoShift shifter, Shimano MF-TZ20 gears, HL corp Zoom fork, Artek linear pull (entire system, can adjust the pull distance on the hand levers,) seat, sparkly orange paint, 1.95" tires, KMC Z51 Chain
Parts that are okay: Feimin resin pedals, Shimano rear derailleur
Parts I am disappointed in: Lubrication (the wheel hubs more so than the chain and gears.) Frame material (steel instead of aluminum)
Any other parts I did not mention are average parts.

Assembly: 30 min if I was in a hurry. Took me maybe two hours, but I was very picky adjusting everything.
Tools needed: 5 & 6mm allen, 15mm crescent wrench, an additional 15mm (socket or wrench)
Extra tools I used: phillips head screwdriver, 17mm crescent wrench, adjustable crescent wrench (one inch/25mm size,) Teflon based bicycle lube.
* Front wheel: Turn the fork around. There is a diagram that shows you how it is supposed to go. Put on front tire with funky washers and nuts. You will need a 15mm wrench or socket on each side. Adjust the bake pads to align with the rims with the 5mm allen
* Handlebars: Use the 6mm allen to adjust the handlebars (rotate them up.) Put the handlebars into the stem where the fork and front wheel is connected. Line up the handlebars. Use the 5mm allen to tighten the handlebars to the stem.
* Brakes: Line up the two silver screwy things that are connected to the hand lever. Pull each brake cable manually, slide it through the holes on the sides of the screwy things.

I ordered this bike for my 10 year old son last week. It arrived at my local Diamondback dealer (I researched it on Amazon, etc.) and he assembled it for me. I love and order often from Amazon, but love to support local businesses as I am one. My local dealer was only $10 above the price listed on Amazon including assembly! I have always seen value in paying more for a bike like this rather than a 'department' or 'big-box' store type. Everything is super solid... very nice Shimano shifting components, brakes are fantastic, great suspension travel on the front fork, handle grips are very nice, the tires are quite chunky/beefy (which every young boy thinks is cool), the seat is easily and securely adjustable and the orange color has a nice pearlescent type metallic finish. I would highly recommend this model to anyone who appreciates a quality product and a bike that can be properly tuned throughout the life :)

This bike is an excellent value for the money. It came about 80% assembled and took about 20 minutes to completely assemble and adjust the derailleurs on the rear wheel. The bike was packaged well and arrived undamaged and unscratched. Also, very cool that they included most of the tools needed for assembly. We bought this bike for my 8 year-old son for his birthday and he loves it. This is a bike store quality bike at a box store price. Every bit as well made and quality components as the similar bike we purchased for our other son at REI last year.

Pros:

Cost and value
Easy set-up
Tools included
Quality construction and components

Cons:

Have to assemble some of it yourself.
Must have some knowledge of how bikes go together and how to adjust shifters.

Overall, very pleased with the purchase and we would make this purchase again in a heartbeat. We will be looking on Amazon again when we are in the market for another kids bike!

First of all, my son's favorite color is orange. So when he saw this orange bike, he wanted it. And now that he has ridden it, he really loves it. He feels grown up like daddy now that he can change gears. He is only 6 going on 7. This bike is the perfect size for him to grow into. We stepped up from a 16" which was just too small now...and almost wore out. I was not sure he was ready for shifting gears and only hand brakes, but he took right to them. He did have some practice with the brakes on his previous bike and scooter, so that was not really expected to be an issue.

All in all, this was the perfect decision for his next bike. I expect this one to last a few years until he is ready for a full size.
