Cleary Gecko 12 Bike Review

Small and mighty, the Cleary Gecko is the ultimate ride for the tiniest of riders! As the smallest kids’ pedal bike on the market available without a coaster brake, the Gecko is the bike of choice for the rare aggressive little rider ready for action. We say rare because this rocking little bike is not ideal for the typical timid first-time rider, but it’s a true pony for a true mini-grom.

To see just how small the 12-inch Gecko is compared to similarly priced 14-inch bikes, we put it to the test with three 3-year-olds of various height and skill levels. In the end, we realized that when paired with the right sized rider with the right riding temperament, the Gecko truly shines. But the window of “perfect fit” is pretty narrow and the average small rider is likely not an ideal fit for the Gecko.

Think the Gecko could be a great fit for your child? From sizing to handlebar-height and q-factor, we’ll cover everything you need to know about the Gecko to determine if it’s the best little bike for your little rider.

Cleary Gecko Review – Results of Our Test Rides

A well-built, thoughtfully designed 12″ bike is hard to come by.  With limited space for cranks and pedals and with tiny legs to maneuver them, it is very difficult to design a quality 12-inch bike. As a result, essentially all 12-inch bikes are hard to ride and are generally a waste of time.  

The Cleary Gecko is the exception. With its small frame, small brake levers, and short crank arms, the Gecko fits and performs beautifully with the smallest of riders. Unfortunately, the beauty of the Gecko is also its potential downfall. The bike is truly tiny, so before we go into the specifics of the Gecko, let’s first address what size child fits on the Gecko.

Cleary Gecko Sizing

Yes, the Cleary Gecko is a small bike, but it is likely even smaller than you think. After testing the Gecko with several kids, we found that is the best fit for kids in 3T. It is slightly too big for kids in 2T (but still usable for some) and much too small for kids in 4T clothes. So the window of fit is pretty narrow.

Also, keep in mind that the Gecko is not compatible with training wheels, so unless your tiny preschooler has already mastered a balance bike, the Gecko likely isn’t the best bike for them. Additionally, if your young balance bike master has an inseam greater than 16″, a larger 14″ bike is likely to be a better fit for them, and will last much longer.

Does a Child NEED To Be Riding a Bike This Small?

Even if your child is in 3T clothes and has already mastered a balance bike, it’s very important to honestly ask yourself if your child wants to move up to a pedal bike. Most kids in 2T and 3T clothing are more than happy to continue to ride their balance bikes.

Far too often parents buy little bikes, such as the Gecko, thinking they can convince their child to move up to a pedal bike at a young age, but it often backfires. Balance bikes are easier to ride than pedal bikes and many preschoolers prefer them and hesitate (or refuse!) to transition to a pedal bike. As a result, these small pedal bikes often sit unused and by the time the child is ready to start pedaling, they have already outgrown the bike.

What size/age child fits on the Cleary Gecko?

The Gecko has a seat height range of 15″ – 17.75″. To get a good feel for how the seat height correlates to the child’s inseam and clothing size, we put the latest 2021 model to the test with three 3-year-olds ranging in height between 37″ to 42″ tall.

TESTER #1: Barely 3-years-old, 37″ tall with a 13.5″ inseam in 2T clothes. Gecko seat is set to its lowest height of 15″.

Having just mastered gliding on her balance bike, this tiny tester was very interested in learning how to pedal a bike! While the Gecko’s freewheel did allow her to practice the pedaling motion (along with help from mom or dad), the seat was too tall for her to touch the ground with her full foot.

Being able to touch the ground with their feet squarely on the ground is essential for new riders. This allows them to easily start and stop the bike while still learning to master pedaling.

While seasoned pedalers (adults and kids) should ride with the saddle raised higher so the rider can only touch the ground with their tip toes, new riders need the comfort and safety of being able to touch with their full foot in order to allow for safe starts and stops on the bike.

For a tester of this size, we would recommend allowing them to happily continue to ride their balance bike. If they have truly mastered their balance bike and are chomping at the bit to get pedaling, encourage them to eat their veggies because they are going to need to grow a bit before it’s going to be a good fit!

TESTER #2: 3-years-old, 39″ tall with a 16″ inseam in 3T clothes. Gecko’s seat height is set to 17″ (almost maxed out). Of the three testers, he is the best fit on the bike.

This little tester’s first experience of pedaling a bike was on a Gecko. As a master of his balance bike, he was ready for pedals and the Gecko got him up and pedaling within a week. After learning to pedal, we moved the seat up about an inch to allow him more extension when pedaling, which still allows most of his foot to touch the ground to allow for easier starts and stops.

TESTER #3: 3 years 8 months, 42″ tall, 18″ inseam in 4T and size 5 clothes. The seat on the Gecko is maxed out at 17.75″

This young rider has been successfully riding pedal bikes for 10 months and as a result, no longer needs to have the bike saddle set low enough for her to touch the ground with her full foot. The maximum seat height of the Gecko, however, does not allow the seat to go tall enough for her. The Gecko is simply too small for her. She is a much better fit on Cleary’s larger 16-inch Hedgehog as shown below.

Cleary Gecko or Cleary Hedgehog?

As shown above, our 3-year-old with a 16″ inseam fit great on the Gecko, but our 3-year-old with an 18″ inseam was much too large for it. With the minimum seat height of the Hedgehog being 17.5″, we found new riders with inseams of at least 17″ or experienced riders with inseams at least 16″ to be a better fit on the Hedgehog than the Gecko.

For inexperienced pedalers with inseams between 16″ and 17.5″, neither the Gecko nor the Hedgehog will be a great fit. A 14″ bike, such as the Prevelo Alpha One, woom 2 or Guardian Ethos 14 would be a better choice.

Weight

When dealing with the smallest of riders, weight is just as important as size. Ideally, a bike should weigh as close to 30% of a child’s weight as possible, but with smaller and lighter 3-year-olds, a weight closer to 40% is much more likely.

As tested with the freewheel option (the coaster will likely weigh about a pound more), the Cleary Gecko weighed in just under 15 lb. at 14.85 lb. The weight wasn’t an issue for our two taller 3-year-old testers but was a bit much for our tiny 37″ tall tester. We assume the weight wouldn’t be an issue once she grew a bit, but it’s hard to say.

While we aren’t aware of a lighter 12″ bike on the market, for super petite kids, the Prevelo Alpha One and woom 2 bikes are only slighter taller than the Cleary Gecko, but they do weigh a pound or two less.

Performance, Geometry and Q-Factor

Due to his great bike fit and skill level, Tester #2 above became our main tester for the Cleary Gecko. As a confident master of his balance bike, he was more than excited and very ready to get started on a pedal bike. After patiently waiting months for his Gecko to arrive, he was ecstatic the day it finally came in.

After a couple of days practicing the pedaling motion (more info about how we accomplished this below), he was ready to start pedaling on his own. After a few attempts, he finally got it and was off to the races!

Within the first day of learning how to pedal, he was able to ride considerable distances on his own. He quickly fell in love with the sense of adventure and independence the Gecko provided.

Gecko’s Aggressive Geometry

To make sure he wasn’t just in love with pedaling in general, we want to get him on another small bike so he could compare the two experiences. Once fully comfortable pedaling, we swapped his beloved Gecko for the slightly larger and more upright woom 2.

At first, he appeared to love the nimbleness and light weight of the woom 2. But much to our surprise, that love quickly waned. As an aggressive and very eager rider, he complained that the woom 2’s handlebars were getting in the way and were too big. He wanted to lean into his bike and tackle the world around him and the upright geometry of the woom 2 simply didn’t fit his riding style.

While both bikes are great, they are simply designed for different types of riders. The woom 2 is a pretty universal “best fit” for most beginning riders who are usually more comfortable sitting up as they ride. The Gecko is designed for the ambitious rider who wants to lean in and embrace every jump and ramp available to them. This level of ambition isn’t as common at this age and size.

Wider Q-factor

To help ambitious riders have a “wider base”, the Gecko is unique in that it intentionally features a wider q-factor. The q-factor is essentially the distance between the inside of the pedals. This is an important measurement as it determines how much the child has to splay their legs in order to pedal the bike. The more splay, the less efficient the pedal stroke.

With crank arms that angle outward, as compared to straight crank arms on the woom 2, the Gecko has a q-factor that is about 2 inches wider than the woom 2. Considering kids’ hips are already pretty narrow, a 2″ difference is a significant difference for a preschooler!

image showing the wider q-factor on the Cleary Gecko as compared to the woom 2

As a result, when pedaling the Gecko versus the woom, our 3-year-old tester had to splay his legs out much wider on the Gecko. For most kids, this wider stance is less desirable as it reduces the efficiency of each pedal stroke. In fact, the Gecko’s wide q-factor is the second major reason (behind aggressive geometry) why we do not recommend the Gecko for timid to average riders.

Cleary, however, intentionally made the q-factor wide to help create that wider base for ambitious riders. As young, ambitious riders begin to gain confidence on their bike, they often begin to stand up and be more playful on the bike. Of our three testers, our main ambitious rider (shown above) surprised us and had no issues pedaling the wider bike! The other two testers much preferred the narrower q-factor on the woom.

Cleary believes the wider base (or q-factor) helps the rider feel more stable and can encourage them to continue to explore new jumps and tricks. While our little rider wasn’t quite advanced enough to try any tricks on the Gecko, we can say that we have seen this benefit on the larger 16″ Hedgehog.

U-shaped Handlebar

Unlike previous versions, the 2021 update to the Cleary Gecko now comes standard with a u-shaped handlebar instead of a flat handlebar. We found the older, flat handlebar to be too low and too aggressive for most riders, so the slight rise is a welcomed addition.

close up image of the u-shaped handlebars on the cleary Gecko

Even though the handlebars are higher, they are still quite low compared to other bikes with similar minimum seat heights, such as the woom 2. As pointed out previously, the difference in body positions created by the various handlebar heights appeal to different types of riders. More aggressive riders tend to favor lower handlebars.

image of the Cleary Gecko next to the woom 2

Lower handlebars force the rider to place a larger percentage of their weight on the handlebars, which places more weight on the front tire. This centers the child’s weight more evenly on the front and back tire and helps the child to feel more centered on the bike and can help them be more playful.

The downside of the Gecko’s low handlebars is that even a slight turn can cause the rider’s knee to hit their arm. While our little testers didn’t complain when this happened, it is a common complaint of the Gecko by other parents.

To be fair, our young tester also experienced this with the woom 2, but as you can see, the higher handlebars of the woom 2 allowed his knee to slide under the handlebars and allowed for a much tighter turn.

The Benefits of Small Bikes without Coaster Brakes

The Gecko is the smallest bike on the market that has an option for a freewheel hub, which eliminates the coaster brake (back pedal brake). We love bikes with freewheels because coaster brakes are notorious for slowing down a child’s ability to learn the proper pedaling motion. This is especially true for balance bike graduates!

The problem with coaster brakes is that they don’t allow you to pedal backwards. When learning to pedal a bike, young riders mistakenly pedal backwards quite often! On a bike with a coaster brake, their backward pedaling motion is quickly and unexpectedly met with an abrupt stop, which typically leads to a fall.

Getting a bike started from a standstill is also easier without a coaster brake as it allows kids to easily move the bike’s pedals into the “start position”. The start position is when one pedal is positioned in the upmost position on the bike, which allows the rider to get the most momentum on their first pedal stroke upon getting started.

For experienced riders, coaster brakes also lead to issues as kids (and adults) often pedal backwards when losing their balance, especially when going uphill. With a coaster brake, this ability to help regain your balance by pedaling is no longer an option.

Bikes with a freewheel hub do not have a coaster brake, so accidentally pedaling backwards isn’t an issue.

Gecko’s Dual Hand Brakes

Bikes without coaster brakes would not be safe without quality, easy-to-use dual hand brakes! With small-reach levers and responsive Tektro brake components, the brakes on the Gecko performed great for our preschoolers.

With powerful dual-hand brakes, however, comes the opportunity and importance of teaching proper braking technique. In order to help our young riders learn to brake with just the right hand (back brake) or with both hands, we placed a piece of colored tape on the right brake lever to remind our young preschooler which side was his right side :).

Gain Ratio

Another feature to always consider when purchasing a single-speed bike is the bike’s gearing. The Gecko features a pretty low gain ratio of 2.96. As a comparison, the Prevelo Alpha One has a gain ratio of 3.7, while the woom 2 has a 3.71.

The low gain ratio of the Gecko means that it will require less effort to get started compared to other bikes, but in turn, it will reach a lower maximum speed than bikes with a higher gain ratio.

For aggressive riders who like to tackle ramps and jumps, the lower gain ratio of the Gecko will allow them to power up obstacles faster and easier.

One word of caution about the Cleary Gecko is that a chain guard does not come standard on the bike, but Cleary does have one available upon request. As a result, make sure your child does not wear baggy pants while riding the Gecko as they could get caught in the chain.

Street Tread Tires

The Cleary Gecko 12 comes with a multi-use tire that provides plenty of cushion and traction for use on mainly paved surfaces. While we did not test the bike out on any dirt trails, we don’t anticipate any problem with the tires performing on hard, compact dirt trails, but would advise again taking on really aggressive trails.

Learning to Ride on the Cleary Gecko

So if you’ve come this far and believe the Gecko is the best little pony for your little grom, here’s a quick tip to help them learn the pedaling motion of the bike.

Before you have the child try to ride the bike, get a 4×4 piece of wood about 8″ long (or something similarly shaped) and prop the bike up on the frame of the bike as shown below. Then while holding the bike in place, have the child practice pedaling the bike. At first, they will accidentally pedal backwards, but with time they will master the correct forward motion.

Once they have mastered pedaling, allow them to start riding, but make sure they “run” on the bike before they begin to pedal. Having kids push the bike with their tiptoes while their legs are behind the pedals is a great way to get started without worrying about their legs hitting the pedals. Getting started on an area with a slight decline is also beneficial to help them gain momentum faster.

Once moving and the bike is stabilized, have the child begin to pedal. It may take a couple of tries, but in time they will be up and pedaling on their own!

Cleary Gecko 12 vs. Other 14″ Bikes

While the Cleary Gecko 12 is the smallest kids bike on the market (that we know of), it certainly isn’t the smallest by much. The Prevelo Alpha One (14″ bike) and the Guardian Ethos 14 both have minimum seat heights which are only about 0.5″ taller than the Gecko’s. Both bikes also come with a freewheel option.

Like the Gecko, the Prevelo Alpha One has low-rise handlebars, which will make for a more aggressive body positioning on the bike (but not as aggressive as the Gecko). It also has a much higher gain ratio, which will be beneficial if you plan on riding longer distances. Like the Gecko, however, the Alpha One is small, and kids with an inseam of at least 17″ are better off on Prevelo’s 16″ Alpha Two.

The Guardian Ethos 14 is slightly different than the others in that it has a high-rise handlebar, which makes it better for timid and average riders compared to more aggressive riders. The upright position, as well as a longer seat post, do allow for more room for growth on the Guardian 14 versus the other 14 inch bikes.

Having tested all three bikes, we can confidentially say that they are all great bikes, but the bike that is best for your child really depends on your child’s size and riding ability.

Cleary Gecko Bike Review Bottom Line

With an exceptional build quality, a freewheel hub option (to eliminate the coaster brake), aggressive geometry, as well as a wider q-factor, the Gecko is uniquely designed for the tiniest of mini-groms in 2T/3T clothes.

What makes the Gecko top-notch for ambitious riders, however, also makes it less than ideal for your average first-time rider. Timid riders (which most first-time riders are) are better off on a more upright bike such as the woom 2 or the Guardian 14.

If you do believe your little rider is ready for action, be sure to check and double-check your child’s inseam prior to ordering to make sure the Gecko will be a great fit from day one. The Gecko is likely much smaller than you think and your little one may be better off on a larger 14″ or 16″ bike.
