When choosing a bike for kids, weight is one of the most important factor to consider. A lightweight bike makes it significantly easier to learn how to ride a bike. A lighter bike makes it easier for kids to handle, with easier starts, stops, and maneuverability. That’s where the Biky Air 20 shines—it’s the lightest 20” kids’ bike available, weighing just 14.8 pounds.
This is absolutely amazing. For comparison, the next lightest bike option that I could find weighs 17 pounds, and those three extra pounds can make a noticeable difference in how easy the bike is to control and how easy it is to learn to ride a bike. If you want a bike that allows your child to ride farther, learn faster, and enjoy every moment, the Biky Air 20 is a fantastic choice.
Key Features of the Biky Air 20
The Biky Air 20 is designed with kids in mind, with every detail focused on making it perfect for young riders. Instead of shrinking an adult bike, Biky created a bike that meets the unique needs of children. The founders of Biky wanted to offer an ultra-lightweight bike that was also affordable, something the market was lacking. So, they built their own bikes to solve that problem. The result is a high-quality, lightweight bike that’s easy for kids to use and still affordable for families. Here are some of the key features of the Biky Air 20.
- Size: 20 inches
- Age: 5-8 years
- Weight: 14.8 lb
- Height: 43-51 inches
- Inseam: 22-29 inches
Biky bikes are made with an aluminum frame that is lightweight yet very durable. It was designed specifically to have a lower center frame to help kids be able to get their leg over the frame without tipping over or catching their foot on the frame. I have seen a big difference between my kids getting on and off a Biky and another popular brand of bike that has a higher center frame.
The fully enclosed chain guard is a great feature, which prevents clothing or fingers from snagging on the chain, ensuring safety during the ride. I had never seen this feature on a bike before checking out Biky bikes and I love it. At first I was a little skeptical because I thought it would be more difficult to take care of the chain with the guard in place, but after a little research, I found that the chain guard is removable for maintenance, such as lubrication, which is essential for the longevity of the bike. If you’re wondering how it works, check out this video that shows exactly how to take off the chain guard and how to apply chain lubrication here. (It is in another language but with the English subtitles on, it’s very easy to understand. The founders of Biky started in Europe under a different name and they have now begun to sell in the United States which is why the video isn’t in English.)
Biky has found that you will need to add lubricant less frequently because the chain guard keeps and protects the lubricant. It also helps my kids keep their hands clean because they don’t get grease on them when they touch the chain.
Another great feature of the Biky Air 20 is that the brake cable is integrated into the bike frame. When the cables are integrated it helps protect the cables from damage and exposure to the elements which improves longevity. This is an excellent feature typically found only on high-end adult bikes, and it not only extends the bike’s lifespan but also reduces the need for maintenance.
The seat post features a quick-release clamp that allows for easy height adjustments without tools—ideal for growing children. Another feature that I really like about Biky is that the bike comes with two hand brakes for the front and rear tires. Unlike many other bikes in this size that use coaster brakes, our kids found these hand brakes much easier and more intuitive than the pedal-back brakes.
The biggest feature that stands out to me is how lightweight the Biky Air 20 is. Biky designs their bikes so that they are ultra-lightweight, they want to ensure that the bike never exceeds 30% of your child’s weight. THIS IS AMAZING!!!
Biky Air 20 Sizing
- : 20 inches
- Age: 5-8 years
- Weight: 14.8 lb
- Height: 43-51 inches
- Inseam: 22-29 inches
The Biky Air 20 is designed for kids aged 5 to 8, making it a great option for growing kids. My tall five-year-old fit the bike perfectly, with room to grow into it further. For my seven-year-old, the bike was slightly on the smaller side, especially in terms of seat height and frame size, but still manageable for short rides. If your child is on the younger end of the age range or smaller in stature, this bike will be a great fit. For taller or older kids, it might be worth considering the next size up to ensure they get the most out of it. Overall, the Biky Air 20 offers an excellent balance of size and weight for younger riders learning to ride confidently.

Assembly and Maintenance
Ordering the Biky online is straightforward, and the bike arrived quickly, just a few days after placing the order. Assembly was very easy, even our kids could help. It comes with all the necessary tools and only took us about 20 minutes from start to finish.
Biky backs its products with a five-year warranty on the frame and forks, with other components covered for one year. Regular maintenance is important to ensure safety and longevity of the bike. Keeping a bike in good condition extends its lifespan, offering better long-term value and reducing the need for frequent replacements. If you have questions you can check the handbook here for more information about how to keep the bike in good condition.
Initial Impressions of the Biky Air 20 Bike
The feature that stood out the most on the Biky Air 20 is how incredibly lightweight it is—just 14.8 pounds—making it far lighter than most comparable models. Finding a kids’ bike this light is almost unheard of, as similar lightweight options typically weigh at least 2-4 pounds more. When choosing a bike for a child, weight is one of the most important factors to consider because it has the biggest impact on their riding experience. A lightweight bike like this makes riding much easier and more enjoyable, helping kids handle, pedal, and steer with minimal effort. The reduced weight also makes starting, stopping, and maneuvering simpler, which is key to improving safety and building confidence. I’ve noticed a big difference in how easily my kids can handle Biky bikes vs other brands, which has boosted their confidence so much!
Another feature that stood out to me is the low center bar on the frame, which makes it easy for kids to get on and off the bike. This thoughtful design is especially beneficial for kids because it helps eliminate the struggle of getting on and off of the bike. I noticed that our five-year-old had no trouble getting on and off the 20″ bike completely on their own. This accessibility is ideal for kids just learning to ride, giving them independence and reducing frustration. Overall, the low frame and lightweight design make this bike an excellent choice for kids starting their cycling journey.
The Biky Air 20 features a single gear, making it a simple and straightforward option for beginners. While this is ideal for beginners who are just learning to balance, pedal, and steer, more experienced riders might prefer a bike with multiple gears to tackle hills or increase speed on varied terrain.
However, the simplicity of a single gear has its advantages—it reduces maintenance, eliminates the need for gear shifting (which can be confusing for some kids), and allows riders to focus entirely on mastering the basics. If your kids are just learning to ride or sticking to flat paths and trails, a single-gear bike is often the best choice, providing a smooth and manageable riding experience.
Performance and Handling of the Biky Air 20
The Biky Air 20 stands out as a well-made, high-quality bike, and its lightweight design is easily our favorite feature. When choosing a bike for kids, weight plays a huge role in ease of use and overall handling. A lighter bike allows children to ride with more control and confidence, helping them master cycling skills much faster. It also minimizes the strain that heavier bikes can cause, enabling kids to ride for longer without getting tired.
My five-year-old loves how easy it is to lift this bike on her own—something she couldn’t do with her previous, heavier bike—and now rides much longer than before, and is always begging us to take her for rides. We love that biking has become so easy for her that she’s always wanting to ride more!
The tires are another highlight, offering solid durability for a variety of surfaces. They perform perfectly on flat dirt trails and sidewalks, which are exactly what a 20” bike needs. The lightweight wheels and tires make steering and pedaling smoother and easier for young riders. I also appreciate the bike’s low center frame, which makes getting on and off incredibly simple for kids. The only downside my daughter mentioned was the lack of a kickstand, but overall, this bike has been a really great upgrade.
Overall Thoughts on the Biky Air 20
The Biky Air 20 is an exceptional choice for kids learning to ride and get more confident on a bike. Its thoughtful design—particularly the ultra-lightweight frame and user-friendly features—makes the learning process smoother, safer, and more enjoyable for kids learning to bike.
Throughout this review, the Biky Air 20 has exceeded our expectations, from its durability to its outstanding performance on a variety of terrains. For parents looking for a reliable, safe, and easy-to-handle bike, the Biky Air 20 is an investment worth making. Whether your child is enjoying casual rides or developing a lifelong love of cycling, this bike is up to the task. I recommend the Biky Air 20 to any family seeking a long-lasting, high-quality bike for their kids.
