Great value in a kid's mtn bike
I have the old version of this bike and it has provided great value & performance for the past couple years. My son is 10 and it fits him perfectly. He has ridden it downhill & bike parks & wilderness trails at Solitude, Southern Utah, Steamboat, and Trestle at Winter Park. I upgraded the rear derailleur, and put Maxxis tires on after year one. I'll be upgrading him to a dual suspension soon, but if your kid wants to get into mountain biking this is a perfect starting point!
Good value...only if you're a bike mechanic
To cut to the chase...you're better off either buying one of the REV bikes without a 'fake' front shock that isn't meant for serious riding, or going for a more expensive bike with an actual air shock. That said, this has been a great bike for my 9-year-old son, and is serving well as a high-value transition trail bike before he is ready to step up a level in his riding. I mean, who wants to spend $1,000 for a bike your child is going to out grow in one or two years? The problem is that you get what you pay for, and to make a bike this affordable they had to cut some corner. The tires are not good, and the front shock actually has a sticker on it warning not to use for serious off road riding. I mean, if the fork isn't mean to used for serious mountain biking, why put it on a mountain bike? The fork is good enough for basic trail riding, but not anything serious, and def no jumps or anything like that. Also, the tires, shifters and rear mech are basically junk. I replaced the tires immediately, and the shorter after the rear mech went into the wheel and broke, and replaced it and the shifter with parts off an old bike. So with an additional $400 so of new parts, and the skill of a former bike mechanic, it works great. So, in sum, if you think your child is going to do serious mountain biking, you're going to have to pay more for something like a Woom bike. Cheers.
Delicate Mt. Bike
I love the color and how the bike looks. We added extras like a kick stand, lights and extra reflectors but considering it's a mt bike I expected it to be more durable. I've had to bring it back to the shop because of the derailer getting bent or broken. Also, I thought the brakes were rubbing, making a noise, I had them look/fix it only to find out after I paid that it wasn't even the breaks that were squeaking. I took it back because I could still hear it and they fixed/oiled another part and never offered a refund. My child is only 11 and rides on the streets mostly. No other issues than that.
Best Bang for the (Young) Buck
Great bike so far! Best bang for the buck out there for a 24" wheel size. Please with the choice so far! Considered Cannondale, Canyon, Trek, and Kona - no one matched the features and hardware w/ a comparable price point as the Co-op Rev DRT 24.
nowhere to mount a water bottle cage
TL;DR: there’s no water bottle mount on this bike. So it’s a kids bike that can’t carry water. So far we are still in the honeymoon phase with this bike, but, I’m very disappointed to discover after the purchase that there is nowhere to attach a water bottle cage. So my daughter is now required to wear a backpack in order to carry H2O with her on our neighborhood family rides. She doesn’t like not having a water bottle on her bike, and she doesn’t like needing someone else to carry water for her. This could end up being returned for the simple reason that she can’t carry her own water on the bike.
Great bike, terrible wheel/tire set up
Well, the bike itself seems pretty decent and I appreciate the hydraulic disc brakes. A lot, the wheels and tires quickly became a sore spot for us. We live in Arizona and my daughter parked both tires almost immediately on can die in the rocks. We went into REI to ask them if we could do slime or tubeless, or anything to make sure this doesn’t happen again and they basically told us there was nothing that they could do. I have never seen such a paperthin tire in my life. This just doesn’t make sense.
Excellent Bike for Young Riders
We bought these bikes as an upgrade for our 7 and 9 year old. They are just the right size with room to grow. The easy handle shifter with a single front sprocket is great for getting them used to learning how to appropriately use gears while riding without being too complicated.
Entry level components - borderline dangerous
Cheap components and build quality ($500+ kids bike?). breaks have a ton of play, detailer rubbed from the first ride, the front wheel came off causing my 8yr old to give over the handlebars resulting in two staples. Save the money for less bells and whistles.
