Priority Start 20 Review – Results of Our Test Rides

Jumping up from a 16″ to a 20″ bike is a big step.  Of all the things a parent needs to consider, in addition to price, weight, geometry, and gain ratio, gears are now an option.  For mountain-bike-riding kids or those riding on long road rides, gears are essential, but for the average neighborhood rider, are gears really necessary? 

Geared bikes add an additional level of complexity to riding for kids as well as for parents trying to maintain the bike.  Single-speed bikes, however, can restrict the length and variety of terrain a child can go on. The Priority Start 20 is the perfect in-between solution, offering the simplicity and easy maintenance of a single-speed but with the gearing options of a traditional geared bike.

We put the Priority Start 20 to the test with a 5, 6, and 7-year-old to see how they faired on the Priority. From long paved biking trails to cruises around the neighborhood, the Priority quickly became a favorite amongst the group.

Priority Start 20 Performance

Love at first ride, our main 6-year-old tester was pure smiles and was eager to keep riding.  From cruising around the neighborhood to keeping up with his older siblings on longer rides, the Start 20″ was quick and responsive and easily held its own.  With a lightweight frame weighing only 19.6 lb., the Start didn’t hold back our average-sized 6-year-old tester from cruising up hills or leaning through turns. 

While he has access to many other geared bikes, the Priority quickly stood out for offering a smooth and comfortable ride on paved surfaces. Designed for city riding, the Start features smoother street tires (as compared to the standard “multi-use tire”) that quietly and quickly rolls over the pavement.

Climbing a hill? No problem, with a quick click of the shifter, the internally geared hub of the Priority quickly goes to work. Want to catch some speed and lay down some rubber, “click, click” and off the Start goes.

While the three gears of the Priority don’t provide near the same amount of gearing choices as other bikes, it was more than sufficient for our neighborhood rides. For more ambitious riders tackling steep inclines, the Start wouldn’t be our first choice, but for the vast majority of rides that 5 to 8-year-olds go on, the Start 20 is right at home.

What size child is the Priority Start 20 best for?

Perfectly sized for our tester in size 5 clothes, the Start 20 is small enough to provide a comfortable transition from a 16″ bike, while being large enough to provide plenty of room for growth.  With a seat height range of 22″ to 28.5″, the Start is smaller than most 20″ bikes on the market and has significantly higher quality components and a better overall design than bikes found in big box stores.

We tested the Start on kids with inseams that ranged from 21″ to 26″ and they comfortably fit on the Priority without any fit concerns. With 21″ inseam, our 6-year-old tester provided a perfect fit while still offering plenty of room for growth.

Our taller 7-year-old tester with a 24.5″ inseam (who is riding with the seat higher than it should be!) still fit great on the bike, but the bike offered much less room for growth. To ensure at least a full year or more on the bike, we wouldn’t recommend the Start 20 for a child with an inseam over 24″.

For kids a little too short for the Start 20, Priority also offers a Start 16 with a seat height range of 18.5″ – 23″.   For taller kids, the Start 24 has a seat height range of 27″ – 34.5″.  All of Priority’s Start models feature belt drives and internally-geared hubs.

Priority Start 20 Components

Grease-free Belt Drive

Smooth, sleek, and certifiably cool, the Start 20 comes with a belt versus a chain.  With no need for grease, the belt is clean to the touch and won’t leave you finding surprise grease stains on your child’s pants and hands, or on your own fingers!

It’s also highly unlikely that a belt drive will ever fall off, minimizing the potential for the drama of mid-ride chain problems. For added safety, the Start also comes with a chainguard to prevent clothing from potentially getting caught in the belt.

Internally-geared Hub

The Start 20 featured an internally-geared hub which allows the gearing of the bike to take place inside the hub of a bike, versus with a bulky derailleur. Instead of a derailleur moving a chain up and down a cassette, the Start’s hub smoothly changes the gearing of the bike inside an enclosed rear hub. 

With no external moving parts, the gearing system on the Start requires very little maintenance and also provides much smoother gear changes. Derailleurs are perhaps the most delicate part of a bike, and with the way kids throw their bikes around, are the most likely to get damaged and cause serious problems on a kid’s bike. This, of course, is not an issue with the Priority 20 because it doesn’t have a derailleur!

Priority Start’s Internally-geared Hub vs. Traditional Bulky Derailleurs

Comparison of an internally geared hub versus on a Priority Start 20 versus a traditional derailleur

An additional advantage of an internally-geared hub over a derailleur is that the bike doesn’t have to be moving to shift gears. If only we had a dollar for every time we’ve shouted, “Don’t shift gears if you’re not moving!!”

On a traditionally geared bike with a cassette and a derailleur, shifting while the bike is standing still can cause the chain to jump up and down as it shifts roughly while the chain settles into place. Over time, this can cause the entire shifting system to become less responsive and in need of expert tuning. And of course, kids do this all the time! Just one more reason the internally-geared hub really is a big win for kids’ bikes.

Shifters and Brakes Levers

1, 2 or 3.  With the simple twist of the shifter, our tester was easily able to change the gears on the Start.  No debating between which of the 7 gears are the best for the ride, the Start makes it easy – 1 for downhill or extra speed, 2 for regular riding, and 3 for hills or slow and easy cruising.

Easy-to-Use Shifters and Brake Levers

Properly sized for young riders, the Start’s dual brake levers require minimal effort to activate and can easily be adjusted to bring the brake lever closer to the grip of small hands for easy reach.  While the brake levers aren’t as high-end as those found on woom or Prevelo, the performance did not disappoint.


Designed for comfort and ease of use, the Priority Start 20 has a comfortable upright position that is ideal for the average young rider.  Not too upright to prevent kids from being able to shift their weight around, and not too aggressive to tire kids out on longer rides, the Start provides a comfortable, fun ride. 

Priority Start’s Comfortable Upright Geometry

Compared to the Pello Rover, which is designed for a more aggressive rider taking on basic trail riding, the Priority is visually more upright.

Padded, Adjustable Saddle

Not skimping on the seemingly minor details, the Start offers a comfortable padded saddle on rails for front-to-back adjustability.  The seat also tilts up to down to help to alleviate any potential issues with pressure points on the saddle. Our testers had no concerns with the saddle, but knowing a saddle can be adjusted if needed is a big win

For easy seat height adjustments, the Start also has a quick release seat post clamp.

Priority Start 20 vs. Early Rider and Cleary Owl

Uniquely built with three gears in an internally-geared hub and a belt-drive, there are few very widely produced 20″ bikes that directly compare to the Start.  The Early Rider Belter 20 is similar to the Priority Start as it also has a belt drive and an internally-geared hub, but it is designed for a much more aggressive rider (more leaned in geometry) and is also about $200 more than than the Start.

The Cleary Owl 3-speed 20″ bike also features an internal-geared hub as well but is equipped with a chain rather than a belt drive. Like the Early Rider, however, the Cleary Owl is also designed for a more aggressive rider.

All in all, the Priority is an amazing and unique bike that offers a fun and comfortable ride, with minimal or any maintenance, for neighborhood riders sticking mainly to paved surfaces.

Priority Start 20 Bike Review Bottom Line

Not too simple, not too complex, the Start is the perfect 20″ bike for young riders ready for adventure, but not quite ready for the complexity of 7-speeds and a finicky derailleur.  Easy-to-use and a joy to ride, the Start 20 is a standout choice for neighborhood riders aged 5 to 8.
