Lightweight and streamlined

We tried a heavier bike before getting this one, and the lighter weight really makes a difference!

Fantastic Kids' Bike!

I bought the super lightweight Biky Air 20 bike for my 7-year-old son, but it is so well-designed that even my 5-year-old is able to ride it with ease. As a parent, I am incredibly happy with this purchase. It strikes the perfect balance of being extremely safe and lightweight, while still being a fast and fun bike for the kids to ride. Highly recommended!

A lovely addition to our family rides

My son has so much fun riding this bike, and we absolutely love it! It’s very lightweight, and the shipping was excellent—the bike arrived carefully packaged. We’re really happy with it and would definitely recommend it to other families!

Great lightweight bike

Our 6 year old had hard time moving up from Woom 3 bike he outgrew, because all 20in bikes was significantly heavier. Until we found biky, and their 20 in bikes weighs exactly the same as his 16 in bike! He loves his big boy bike!

Great lightweight bike!

We bought it for my son's 7th birthday and he enjoys riding it every day!

It was very easy to assemble and he helped by adding the stickers that came in the box.

It does not come with a kickstand, but I was informed that they will have one available soon.

We cannot be happier with our purchase!

Honest Review - Super light - Best at Pricepoint - Still Not a Cadillac

We have 4 kids and didn't find Biky until our youngest was 7 yrs old...so we've owned many different name-brand kids bikes: burley, woom, REI, Scott,...this one wins for ease of use out of the box, how incredibily light it is and on price point. Most bikes weigh twice as much as this one and the difference is noticeable, especially with kids. Will it hold up as well as the much more expensive woom bike? That remains to be seen. The woom feels more substantial, and holds up well to the beating our kids gave them for 6 plus years and multiple siblings. But it also comes at a price point that is arguably much, much higher. Of course, This review is for Biky. Great bike, great price. If others are out of your price range, this is the company to go with.

My daughter absolutely loves this bike… She was afraid of moving up in bikes and getting rid of her training, wheels, but this bike gave her so much confidence that she was off and loving it within five minutes of getting on it!

It is very light and there was a lot of thought gone into its design, and it is a high quality bike, buy with confidence!

Perfect Bike !

I was looking for the perfect bike for my 7-year-old granddaughter. After doing a lot of research, I decided to go with the 20-inch Biky Bike. The bike is the lightest bike on the market, and the build quality is exceptional. Customer service and shipping were perfect. I highly recommend this company to all my friends and family.

Fantastic Bike!

My 6.5 y/o son loves his Biky Bike! He learned to ride on a heavy bike with coaster brakes about a week and a half before we got his Biky Air 20. He noticed the difference between the two bikes immediately and wants to ride his Biky Air multiple times a day. :) My husband had no trouble putting the bike together. The Biky Air 20 is so lightweight and clearly has high quality components. It is easy for him to handle, and the hand brakes were a very simple transition for him. I put a piece of blue tape on the rear wheel brake (right hand), and he caught on right away. I am so happy with this purchase! It gives me so much joy to see my son so happy and free.

Best experience

We are very happy with our Biky bike! It’s truly incredibly lightweight, and the difference compared to other bikes is huge. It’s so much easier for a child to ride, and you notice it immediately. Super smooth and easy to control. Definitely worth the purchase!

One small suggestion: it would be great if you added a kickstand as an accessory so the bike could stand on its own.

Big boy bike!

We like our new big boy bike and so far, it's been easy to adjust to and fun to ride. Only wish it came with a stand, too! But otherwise, it's turning out to be a good purchase.

Great bike at a decent price

I had a difficult time choosing a bike as I was buying a 16” and 20” at the same time for my kids. I had an older 16” that my dad had picked up for $10 or so, but it was so heavy and my daughter never got the hang of it without training wheels. I thought about Guardian bikes, but the deceptive pricing structure, mixed reviews on quality, and political leanings made me wary of them.

I ended up with a used Woom 3 for my son and a 20” Biky for my daughter. I would say they are similar in quality, very lightweight, and the proportions are just right for kids. My daughter actually started out learning to ride on the Woom (it came a couple days earlier) and then resisted moving up a size because she was nervous. Once we got her to try the Biky it was game over-she absolutely loves it. It is so easy for her to manage and within a few days of riding she is a pro, and I wouldn’t consider her especially coordinated. I love the cables that tuck into the frame (steering limiter is what they call it I believe) and the brakes are so easy to use (we put a sticker on the back brake so she knows which one to use first). Shipping was fast and it was easy to put together. I would consider it worth the cost-but we got the red on sale and it was the upper end of my budget for a kids bike. My only real complaint is that it does not have a kickstand. At this price point that would be a feature I would expect to see. We did end up adding an aftermarket one but even if Biky made one I would have liked to go that route.

All in all I am very happy with this bike and recommend it to people I know. I will definitely be purchasing again when we are ready for gears/a larger size.

Awesome Bike, But missing sidestand

I recently purchased a 20-inch bike for my 7-year-old, and the bike itself is great. However, I quickly realized that it doesn’t come with a side stand.

Could someone please suggest which kickstand would be the best option for this bike?

Finally found the right bike for my daughter

My 6-year-old daughter's WOOM GO 3 is getting too small. We want to buy her a 20-inch bike. My wife asked me to pick the bike, because I am an engineer. I got furious when I found out that all the other good brands' bikes had shifters and even disc brakes. Seriously? If these designers think we want to spend money on features, they are wrong. We want quality, safety, and the right mindset from the bike designer who understands what a kid needs. Until I found BIKY. They get all the right components. A 6-year-old does not need a shifter, disc brake or suspension. Simple, light, and safe is the priority. I love the simple design and the high-quality components I saw when putting it together. And most of all, the bike chain. OMG. This is the right bike chain for a kid! I had my finger caught in the chain when I was a kid. When I saw the chain, I basically told my wife that no more discussion. So I put the bike together that night. This is my dream bike for my daughter!

Great bike, new size

Got this as a present from Santa for my 5 1/2 year-old. It’s a little tiny bit tall for him, but the previous size down was a little too short so we went for it. He’s already riding an assisted, and he loves his new bike. Only wish it came with a kickstand.

Love it!

I really didn’t want to spend this much on a bike, but after watching my kiddos cousin using a much cheaper bike and her struggles i decided to try it. I definitely think it’s going to be worth it! Sooo much lighter! It’s going to be a Christmas present but so far it’s perfect. Packaged extremely well and fast delivery.

Easy to learn on!

This is my 6 year old daughter’s first 20” bike. Her previous bike dint have hand brakes so she was scared of going too fast. But this bike gave her the confidence she needed to go faster. Not to mention this bike is about 10 lbs lighter than the previous bike she had! Customer service has been great and has been very accommodating. Thank you all! Would definitely recommend this to any parent who wants their child to learn how to ride a bike quickly and safely.

Excellent Bike!

This is my son's second bike and he loves it. His previous bike was a Woom 2 (14" bike) and honestly he had outgrown it for over a year already. His inseam is 21.5" and height is 48". He's 6 years old and he's been riding bikes every since he was 2. He started with a balance bike for almost a year and then picked up the woom pedal bike immediately. I highly recommend this approach and plan to do the same with my other kids.

The Biky arrived within a few days after ordering. The packaging box was slightly damaged (probably UPS fault) but the bike itself was fine. The frame and wheels was well padded throughout. I have no experience with assembling bikes but I was able to easily follow the instructions to attach the wheels and handle bars.

We've had the bike for a month now and we're still satisfied with it. So far we've stuck to just riding around the neighborhood or at the park and it's been excellent. There was no kickstand so I bought a third party one along with a bell.

We're happy with our purchase and I have no doubt this quality bike will still be good for our next child once they're ready in a few years.

Best Bike for kids period!!!

My daughter has been struggling with getting off the training wheels from her old bike that she was to big for. When we met biky at the otter classic my daughter was fearful to get on a bike without training wheels. However, I noticed the details that biky put into creating their bikes with children in mind. The bike is light, so it’s easy to balance. The bike also has chain that (protects) does not expose the gears. This is a very well thought out bike.

Lightweight, well made ride for kids

As a bicycle education professional, I get to see a LOT of different bikes. Biky has quickly rolled to the top of the ones I will recommend for kids, especially those kids who are slight of build and nervous of stature. The upright positioning and lightweight materials promotes confidence and ease of use.

Perfect bike for your little ones!

I found about this bike from a trip to Pretend City. I couldn't believe how lightweight it is and I was impressed with the build quality. I reached out to Biky and they were quick to answer my questions. I immediately purchased the Biky 14 for my 4 year old and waited for the Biky 20 to be stocked for my 6 year old. I received the Biky 20 assembled, but I know from the Biky 14, that it is easy to assemble. If your little one doesn't know how to bike yet, you can easily remove the pedals and use it as a balance bike. My kids both love biking more, especially with matching bikes. Biky's customer service is top notch and if you're local, they will make sure everything is perfect.
