From 12 Inch To 24 Inch Kids Bikes, Rei’s Co-op House Brand Offers Budget-friendly, Quality Bikes For Both Little And Big Kid Riders. The Standard Rei Co-op Cycles Rev Line Is Meant To Rock The Neighborhood, While The Rev Plus Line (only Available In 20″ And 24″ Wheel Sizes) Are Recreational Mountain Bikes With Wide, Knobby Tires For Beginning Trail Use (or Just A Cool Bike For Neighborhood Riding!)

This Review Will Cover 12″, 16″, 20″, And 24″ Kids Bikes From The Rev Neighborhood Line From Rei’s Newly Resigned 2022 Line. The Re-design Resulted In Some Solid Improvements For The 16″ And 20″ Bikes, But The 12″ And 24″ Bikes Need Additional Improvements Before We Can Wholeheartedly Recommend Them. Read Our Full Review Below To Understand What We Loved, And Didn’t, About These Bikes.

REI Co-op Kids Bikes Overview

The Co-op Rev 12″, 16″, And 20″ Are All Single-speed Models With A Coaster Brake, Smooth Street Tires, And Tool-free Training Wheels. The 20″ Model Also Comes With A Rear Hand Brake In Addition To The Coaster Brake.

The Co-op Cycles Rev Cty 24″ Bike Is Similar To The Smaller Bikes But Is Geared. It Also Has Dual Handbrakes (no Coaster Brake) And Does Not Come With Training Wheels.

We Recommend The 16″ And 20″ Bikes. We Do Not Recommend The 12″ And Have Reservations Recommending The 24″ Bike.

Rei Co-op Cycles Rev 12 Inch Bike

While the overall quality of the Co-op REV 12″ bike is actually quite good for the price, we cannot recommend it as a result of its coaster brake being hard to engage. We had two testers, ages 3 and 4, test out the bike and both of them struggled to effectively and safely engage the coaster (backpedal) brake.

The Coaster Brake Mechanism On The Rev 12 Is The Same As Found On Many Other Bikes. To Engage The Brake, A Child Should Simply Pedal Backwards, Which Stops The Bike.

However, The Rev 12 Has Super Short Crank Arms And Very Small Pedals. This Combo Provides Too Small Of A Base For Kids To Effectively Backpedal To Stop. On Our Test Rides, Pedaling Backward While Applying Enough Force To The Pedal Was Too Challenging For Our Testers. With No Safe Braking System To Stop The Bike, We Cannot Recommend It.

As A Point Of Reference, We Found The Crank Arm Length (the Length Of The Bar That Connects The Pedal To The Bike) On The Rev 12 To Be 5mm To 20mm Shorter Than Similarly Sized 12 And 14″ Bikes. The Longer The Crank Arms, The More Leverage Kids Have On The Pedals And The Easier The Coaster Brake Is To Activate. The Crank Arms On The Rev 12 Are The Shortest We’ve Seen On A Bike.

If You’re Looking For A Budget-friendly 12 Or 14 Inch Bike, The Only One We Recommend Is The Btwin 100 14.

Rei Co-op Rev 16 Inch Bike

There Are Many Affordable 16″ Bikes, But Very Few Of Them Are Actually Easy To Ride, And Durable Enough To Pass On To Your Next Kid. Rei Has Done A Solid Job In Making A 16 Inch Bike That Several Of Your Kids Can Enjoy Cruising Around The Neighborhood.

What We Love About the REI REV 16

  • Great Quality, Durability, And Low Weight For The Price
  • Updated Design Of 2022 Model Is A More Comfortable Fit And Riding Experience For More Kids
  • Training Wheels Attach And Detach Without The Need For Tools

What You Should Know Before You Buy

Coaster Brakes (back Pedal Brakes) Make It Harder To Learn To Ride A Bike, But At This Price Point, It’s Hard To Find A Bike Without Them
The Grips Are Pretty Small. If This Bothers Your Child, You Can Easily Swap Them Out.

Geometry Improved Over Previous Model

The 2022 Update Of The Rei Co-op 16 Inch Bike Is An Improvement On The Previous Model. Rei Kids Bikes Have Struggled With Strange Geometry Issues In The Past, So We Were Happy To See Some Small Changes That Make This Little Bike A Better Fit For More Riders.

With Higher Handlebars And A Lower Minimum Seat Height, The 2022 Rei Rev 16 Is A More Natural Fit For A Wider Size Range Of Kids. Its Lower Bottom Bracket And Shorter Crank Arms Help Keep Kids’ Knees From Coming Up As High On The High Pedal Stroke, Making Pedaling More Comfortable And Efficient.


The Rei Rev 16 Has A Seat Height Range Of 20.1″ – 24″. Below You Can See How Two Different-sized 4-year-olds Fit On The Bike.

On The Left, Our Rider Is 42.75″ Tall And Has The Seat Set To 21.1″. On The Right, Our Rider Is 44.75″ Tall And Has The Seat Set To 22.75″. Both Have The Saddle Set So They Can Touch The Ground With Their Tip-toes, And Experienced A Smooth And Fun Ride.

While Our Larger Rider On The Right Can Still Comfortably Ride The Rev 16, The Handlebars Are Much Lower In Relation To Her Waist, And Closer To Her Knees.

This Perches Her More On Top Of The Bike And Her Hands And Arms Are Also Forced A Bit Straight Down, Rather Than Naturally In Front Of Her. That Said, While Not The Most Perfectly Comfortable Fit, It Is Certainly Fine For A Child This Size To Continue Riding This Bike For Several More Months. If You’re Buying A Bike For A Child This Size, The Rev 20 Is A More Appropriate Fit.

The Window Of “great Fit” Is More Narrow That We Would Like On This Bike, But We’ve Found That Issue To Be Pretty Consistent For Budget-friendly Kids Bikes. Overall, The Rev 16 Is A Better Fit And Design Than The Vast Majority Of Budget-friendly 16″ Bikes Out There.

Light Weight Helpful To Young Riders

The Co-op Cycles Rev 16 Kids Bike Is Built With A Solid-quality Aluminum Frame, Similar In Construction To Higher-end Bikes. Its Aluminum Frame Allows The Rev To Weigh Much Less Than Most 16″ Bikes With Heavy Steel Frames.

Since Kids Are Lightweight, It’s Important That Their Bikes Are Lightweight As Well. Ideally A Bike Shouldn’t Be More Than 30% Of A Child’s Weight. Building A Lightweight Bike Is Expensive, But The Rev Series Is Quite Unique In That It Is The Same Weight Or Even Lighter Than More Expensive Bikes.

Training Wheels – No Tools Required!

While we encourage parents to skip training wheels, if you are using them, REI makes it super easy. The arm of the training wheel attaches to the bike’s frame with a large, screw-in, knob. Simply line up the holes, insert the knob, and turn to the right to tighten

Coaster Brakes Aren’t Ideal, But Expected at this Price

Like Most Other Similarly Priced 16″ Bikes, The Rei Rev 16 Comes With A Coaster Brake. Coaster Brakes, Or Back Pedal Brakes, Aren’t Ideal For Young Riders Learning How To Pedal, But They Aren’t Necessarily Problematic For Everyone.

Coaster Brakes Tend To Work Fine For Kids Who Start Off On A Bike Using Training Wheels, But They Usually Cause Confusion For Kids Who Skip Training Wheels By Using A Balance Bike First.

When Balance Bike Graduates Are Learning How To Pedal, They Often Accidentally Pedal Backwards When Learning The Motion Of Pedaling. This Leads To An Abrupt And Unexpected Stop, Which Almost Always Leads To A Fall And Much Frustration.

For Kids Who Learn To Pedal While On Training Wheels, Backpedaling Isn’t An Issue As The Training Wheels Keep Them Upright In The Event Of The Abrupt Stop.

So If Your Child Is Graduating From A Balance Bike, The Coaster Brake May Slow Their Progression, But Considering Essentially All Bikes In The Rev Price Range Come With Coaster Brakes, You’ll Need To Consider Increasing Your Budget To Get A Bike Without One. (unless You Can Catch A Joey 3.5 In Stock!)

Grips are Oddly Sized

The grips on the REV 16 are oddly small, and are actually the same sized grips they put on the 12″ bike. As you can see below, our 4-year-old tester’s hand barely fits on the grip of the 16″ REV (on the left). Compare this to how much more room her hand has on a more standard-sized grip (on the right).

REI Co-op REV 20 Inch Bike

What We Love About The Rei Rev 20

  • Great Quality, Durability, And Low Weight For The Price
  • Upright Handlebars (vs Low Bar) Allows For A Better Fit Over A Longer Period Of Time For More Riders
  • High-quality Tektro Hand-brake For The Rear Wheel
  • Training Wheels Attach And Detach Without The Need For Tools
  • Comes With A Kickstand

What You Should Know Before You Buy

  • Coaster Brakes (back Pedal Brakes) Can Make It Harder To Learn To Ride A Bike, But They Are Standard On Bikes In This Price Range
  • Some 20″ Bikes Come With Gears. This Bike Is A Single Speed, Which Is Ideal For Beginning And Casual
  • Riders This Age. If You’d Prefer A Bike With Gears, The Rev 6-speed Plus Is Rei’s 20″ Geared Bike.

Geometry Improved Over Previous Model

The 2022 design of the REV 20 is very similar to its predecessor with one key difference that has a big impact. Instead of the low, flat handlebar that made the bike awkward and overly aggressive, the 2022 model has a riser handlebar.

The riser handlebar allows kids to sit in a comfortable, upright position. The bar can also be rotated towards or away to adjust the fit as kids grow.

For our 46″ tall (with shoes on) rider, we rotated the handlebars towards her so she wouldn’t have to reach so far. For our 50.5″ tall rider, we rotated them up and out to better accommodate her longer arms and torso.

Handlebars Rotated for Short and Tall Riders


The Co-op Rev 20 Has A Seat Height Range Of 21.5″ – 27″. Our Primary Tester Is 46″ Tall And Has A 20.25″ Inseam (with Shoes On) And Has The Seat Seat To 23.3″. As An Experienced Rider, We Have The Saddle Set So That When She’s Sitting, She Can Touch The Ground With Her Tip Toes.

If Your Child Is Timid Or A Beginner, It Is Safer And Will Build Confidence If The Saddle Is Set Lower, So That The Child Can Reach The Ground With Their Feet Flat. When The Seat Is Set To Its Lowest Point (21.5″), Our Same Tester Can Touch The Ground With Flat Feet.

Tip Toes for Experienced Rider vs. Flat Feet for Beginner

The REV 20 was also a great fit for our 7-year-old tester who is 50.25″ with shoes on and prefers the seat set to 25.5″. Below you can see how both our 4 and 7-year-old testers fit on the bike.


The Rei Rev 20 Is Lightweight For A Budget-friendly Bike. At 22 Pounds, It Is Significantly Lighter Than Competitors Like The Btwin Rockrider (24.3 Lbs) And The Schwinn Koen (27.8 Lbs.). It’s Also Several Pounds Lighter Than The Rev 20 6-speed Plus, Which Weighs 24.5 Pounds.

A Few Pounds Can Make A Big Difference For A Kid’s Desire And Ability To Pedal And Manuever A Bike, And Especially To Ride Up Hills Or For An Extended Period Of Time. Our 4-year-old Tester Flew Up And Down The Ramps At Our Local Skatepark Just Like She Does On Her Much More Expensive Bikes.

Geometry and Fit

The REV CTY 24 has a seat height range of 25.5″ to 31.5″, which is considerably lower than the average 24″ bike found at big box stores or even many bike shops. While the seat height range is comparable to other expensive bikes, the geometry of the bike makes it difficult to ride when the seat is in its lowest position.

When the REV CTY’s seat is set to its lowest position, the bike is hard to pedal as a result of the high position of the pedal on the upswing. As shown below, our 7-year-old 49″ tester can stand over the bike with her toes touching the ground, but pedaling the bike requires a tight knee bend that made riding the REV very uncomfortable. Although she is a confident rider, she was very vocal about her discomfort and difficulty in riding the REV.

Once she got up to a descent speed, pedaling the bike became easier, but the long reach to the handlebars made it challenging for her to maneuver. All in all, it was very clear that she was not a fan of the bike at her size.

Our Taller 10-year-old Tester (54.5″ Tall, Inseam Of 27″), Had No Issues With The Bike Being Cramped. He Quite Enjoyed The Smooth Rolling Hybrid Tires Of The Rev Cty, But Considering He Was Riding With The Seat Height Set At Its Max Of 31.5″, The Bike Offered No Room For Growth.

As A Result, We Believe The Best Fit Range For The Rei Rev Cty 24 Is For Kids Who Are Able To Ride It Within The Seat Height Range Of 27.5″ To 31.5″. While Every Child’s Preferred Seat Height Setting Varies, That Roughly Equates To Kids With Inseams Ranging From 24″ To 26″.

Rei Co-op Cycles Rev Bottom Line

Ei’s Rev House Line Of Kids’ Bikes Offer Great Quality And Confidence (especially If You Have An Rei Nearby!), But Some Models Provide A Much Better Value And Performance Than Others.

After Extensive Testing, We Found The Rev 16″ And 20″ Models To Be Great Options For Parents Looking For A Quality Bike Without Breaking The Bank. The 24″ Rev Cty Was A Fun Bike To Ride For Taller Kids, But We Struggle To Recommend It Due To A Difficult Shifter. Lastly, The Rev 12 We Don’t Recommend At All Due To Its Short Crank Arms That Make It A Challenge For Kids To Quickly Stop The Bike.
