Co-op Cycles - REV 20 Kids' Bike - Red Hot

Category: Bikes

We bought this for our 6.5 yo. It’s a great bike. He’s learning to use the handbrake while still being able to have the pedal brake. Bike is lightweight, easy to ride, and great entry level trails, too.

The bike is light and easy-ish to ride. My son who is 6 and on the taller side and he is still awkwardly reaching for the handle bars Which makes the bike a little hard to steer. Something I hadn’t heard mentioned is that’s the peddles on this bike will do nothing but leave your cliffs legs torn and bloody! Bike could be great with some adjustments.

Impossible to mount training wheels. The rear axle studs have zero additional length for adding training wheels. Quite disappointing for an otherwise pretty nice bike.

This is a fantastic bicycle. It was for

One of the lightest bikes for this type. My grandson loves it!

Bravo it's a amazing bike built really good it good



What tools are needed to put this bike together? 

The bike comes mostly assembled and includes the necessary tools to complete the build.


My son is 9.. 4ft .. What do you suggest?

If he is 4' tall, he is just right for this bike. The 20 inch REV works well for kids who are 4' to 4' 5" tall, which means he can get several years of use out of this bike depending on how quickly he grows.


Can you fit training wheels on this bike?

Yes, you can fit training wheels on this bike. We recommend the Wald 742 Training Wheels Kit found in the link below.


My daughter took a small spill and the front brake piece came unhinged - can’t figure out how to fix.  Any online resources or videos available on small repairs?

We recommend you take the bike to your local REI bike shop for repair.


Is their a recommended height or inseam for the child to fit this bike?

Can I put the Wald W742 training wheels on this bike?

Are alternate gears available to change the ratio for easier pedaling. The bike my daughter has now is very hard to pedal and they use non standard gears. As a result, she does not ride it.

does this seat adjust forward any? I feel like my 5yr old may be btwn 16" and 20". the 20" seems like he may bend forward more to reach the handles. I know the seat raises up and down but by any chance does it tilt forward?  thank you

Is it possible to put fenders on a Coop Cycles Rev20 Kids bike (single speed version) ? If so, what brand/model of fenders ? Thanks

Due to the lack of braze-on mounting points, we do not have a recommendation for fenders for this bike.


Am I right that your size measurements are NOT actual frame size measurements but rather height from ground to top of seat tube? 

The 22 inch standover height measurement is taken from top tube to ground. The wheel diameter is 20 inches which is why we call this the REV 20. The minimum seat height is 21 inches and the maximum is 26 inches which is also taken from measuring from the seat to the ground.


I see the question and response on the "handle bar adjustable". I need clarification. Can the handlebar be raised or lowered?

You can adjust the seat height on this bicycle, but the handlebars are not adjustable.


Can you remove or disable the coaster brake?

No, the coaster brake is not designed to be disabled.


Similar to question above, what is the step-through height of the bike? Distance from ground to the top tube. Trying to determine if my 5 yr old can fit the 20" or needs the 16".

​The standover height for this bike is 22 inches.


Is the handlebar adjustable on this?

​No, this handlebar is not adjustable.


what are the min and max inseam heights for this bike ?

Unfortunately, we do not have minimum and maximum inseam lengths. However, the minimum seat height is 21 inches and the maximum seat height is 26 inches.


I suspect this bike is not training wheels compatible, but can you please confirm? Thanks in advance. Cheers!

This bike is training wheel compatible. Here is a link to our selection of training wheels:
