- Stack Stack is the vertical distance from the center of the cranks to the center of the head tube, measured to the top of the head tube.
- Effective Top Tube Effective top tube is the distance from the center of the head tube to the center of the seat tube/seat post, measured parallel to the ground.
- Seat Tube Center to Top Seat Tube length is the measurement of the seat tube, from the center of the cranks to the top of the seat tube.
- Head Tube Length Head Tube Length is measured from the bottom to the top of the head tube.
- Head Tube Angle Head Tube Angle is the acute angle between the head tube and the ground (measured towards the rear of the bike)
- Seat Tube Angle Seat Tube Angle is the acute angle between the seat tube and the ground (measured towards the rear of the bike).

Surprisingly poor quality
We bought this for our 8 year old. After only a few rides, the handlebar covers began to separate from the frame. After repeatedly readjusting them, my son asked us to remove them — the patterned rubber was hurting his hands anyway. Upon removing the rubber, we saw that the handlebars were already broken/damaged. My son rides hard but has only owned the bike for about 2 weeks. The bike has otherwise been pretty good (the left fear is a little hard for him to turn, but it rides nicely). This is disappointing, though.
Derailleur Failure
Please see other reviews about the derailleur/shifter. I have purchased two of these, one stopped working in six months, the other in less than two months and probably only 4 rides. To make things worse REI will not commit a time to fix, you have to show up and hope they will get you in. Poor quality and even worse service when this seems to be a known issue with this model. Very disappointing when you have to tell your kid their brand new bike doesn’t work correctly and the shop won’t make time to fix it. So much for the REI commitment to quality and service. Sell low quality at a high price and then say, sorry, but you have to wait….
Not what I expect from REI quality
I've been an REI member for almost two decades, and this is the fourth REI bike I've purchased for my boys. Sadly, this is probably the last. The quality of the new Co-op bikes isn't anywhere near the old Novarra bikes -- and that's a big deal with young boys. The two older bikes were absolutely bomb-proof. These Co-op bikes break like wet tissue paper. While the ride of the bike and the fit seems great, the components (namely brakes and derailleurs) are garbage and I've had to bring both of my kids' bikes back in for repairs three times in six months. Go pay up for a brand name bike or be ready to buy multiple cheap bikes from a big box store... it'll be cheaper for you in the end.
Good value for decent kids bike
This is a really decent bike at a good price for kids, providing a lot of value. It seems easy for my kiddo to ride and control. It is a bit on the heavy side but at this price that is not unexpected. My only real complaint is that the reach is pretty long for a kids bike, which is a frame geometry feature I've experienced on adult REI bikes as well. Would be nice if this came with a shorter stem or bars that swept back more (or tweak the geometry in future versions). However, it is hard to find an affordable kids bike outside of the used market so this is still worth it. I recommend this bike to other parents.
Great gearing
Hard to find kids casual 24” bikes wtih enough gearing to make it up hills comfortably. Most come with 1x front chainring, which is good for simpicity, but the rear is usually 7 to 8 speed, which is just not enough for hills. This is perfect with a triple front chainring! I did change out the brakes, and updated the L & R shifters to the click style (makes a HUGE difference as the twist shifters are hard for my kid), all for cheap on eBay or Amazon. Also helps to change out the seatpost to zero offset to reduce the reach, and got an alloy short stem and aluminum bars to replace the stock to reduce weight and further reduce the reach so my kid can ride comfortably. With these few modifications (all on the cheap, just look on eBay or Amazon), the bike is incredible and my kid loves it. The biggest selling point for this bike is the triple front chainring, which makes all the difference for climbing hills.
Sad grandchild
This is a pretty sturdy bike but the handlebars don’t adjust nor do they sell a riser. This bike is too expensive to not have something so simple addressed. My grandson was hunching over the handle bars. He can fit other 24 inch bikes.Also the patterned rubber hurt his hands so your child will need gloves. He loved the color and it the handle bars were able to be adjusted we probably would keep it but we need to return the bike. He was very disappointed.
Poor geometry -- handlebars
I am the 3rd of the 10 reviews posted here to state there is an issue with the geometry on this bike. I purchased this in the late Spring as my son had outgrown his 16" bike. He's barely ridden this because the handlebars are set up in such a way that he is very hunched over and uncomfortable. I literally have it sitting at REI in austin right now because it just doesn't work for him, and apparently it would require an entire new fork to get the height up. I expect we will be returning this and looking for another option. Very frustrating.
Good quality, good price
I purchased the smaller 20 inch, single speed and the larger 24 inch, 21 speed REI coop brand bikes for my kids. Both are of good quality and are competitively priced. No front suspension, reasonable weight, reasonable tire width, good brakes. These are the right design choices.
Great bike for my eight year old
My daughter loves this bike. It is her first real bike, and it is helping her to learn how to be a proper cyclist. So far the design, components, and workmanship are excellent.
Middle of the Road Bike. Poor Assembly.
First impressions are that I'm fairly happy with the bike. It is basic but everything is fairly good. I would have liked to see at least 1 disk brake but its ok. I have built many bikes over the years and realize that this is a kids bike, so I gave it a break on build expectations, however I was very surprise on how bad the assembly was from REI. For instance 1 brake side wasn't touching, front wheel at least 1 inch off center, shifting for both derailleurs were not calibrated, reflectors loose on bike, warped wheels, among other issues. Thankfully I have all the tools and quickly were able to calibrate, tighten and trued the wheels. The reason I find this so bad is that without the knowledge, this could have easily taken 1-2 more trips, and I will need to pour over the rest of the bike to ensure that everything is actually assembled correctly (like bottom bracket, bearing, etc). I strongly recommend buying from a bike shop and paying the extra money unless you know your way around a bike.
