FAQ

Should I choose a Biky by my child's height or by age?

Use height and inseam, and treat age as a guide: the Biky Air 16, a 16 inch kids bike, fits riders 40 to 46 inches tall with a 16 to 20 inch inseam.

Measure the height first, then the inseam: your child stands against a wall without shoes, you put a book between the legs and measure from the floor to the top of the book, then compare both numbers with the table below.

Model	Rider height	Rider inseam	Seat height
Biky Air 12 (balance bike)	31 to 41 in	13.5 to 17 in	12.5 to 16 in
Biky Air 14	37 to 44 in	15.5 to 19 in	15.5 to 19 in
Biky Air 16	40 to 46 in	16 to 20 in	18 to 23 in
Biky Air 20	43 to 51 in	19.5 to 23.5 in	21.5 to 28 in
Biky Air 20 S7	43 to 51 in	19.5 to 23.5 in	21.5 to 28 in
Biky Air 24 S7	49 to 58 in	23.5 to 29.5 in	26 to 34.5 in

If your child lands between two sizes, the smaller bike is lighter and easier to start on, and the larger one leaves room to grow. The Biky Finder asks for your child's age, height or inseam and riding experience, then recommends a model.

Which Biky fits my child's age?

A balance bike for a 2 year old is the Biky Air 12, for riders 31 to 41 inches tall, and the list below runs to age 11. Age is a guide, and height and inseam make the call.

• 2 year olds: Biky Air 12 balance bike, for riders 31 to 41 inches tall. The Biky Air 12 is for 2, 3 and 4 year olds, from 18 months (ages 1.5 to 4).
• 3 year olds: Biky Air 12 if your child is still learning balance, up to 41 inches tall. Biky Air 14 for a first pedal bike, 37 to 44 inches tall. The Biky Air 14 is for 3, 4 and 5 year olds (ages 3 to 5).
• 4 year olds: Biky Air 14 up to 44 inches tall, Biky Air 16 from 40 inches tall. The Biky Air 16 is for 4, 5 and 6 year olds (ages 4 to 6). Between the two, take the Air 14 as a first pedal bike and the Air 16 for a confident rider who needs room to grow.
• 5 year olds: Biky Air 16 for riders 40 to 46 inches tall, Biky Air 20 from 43 inches tall for a confident rider. The Biky Air 20 is for 5, 6, 7 and 8 year olds (ages 5 to 8).
• 6 year olds: Biky Air 16 up to 46 inches tall, Biky Air 20 from 43 inches tall.
• 7 year olds: Biky Air 20 or Biky Air 20 S7 for riders 43 to 51 inches tall, Biky Air 24 S7 from 49 inches tall. The Biky Air 20 S7 is for 5, 6, 7 and 8 year olds (ages 5 to 8).
• 8 year olds: Biky Air 20 or Biky Air 20 S7 up to 51 inches tall, Biky Air 24 S7 from 49 inches tall.
• 9, 10 and 11 year olds: Biky Air 24 S7 for riders 49 to 58 inches tall. The Biky Air 24 S7 is for 7, 8, 9, 10 and 11 year olds (ages 7 to 11).

A 14 inch kids bike and a 16 inch kids bike overlap at age 4, and that's normal. The Biky Finder sorts it out.

What makes a Biky different from other kids bikes?

Weight comes first: a Biky Air 14 weighs 11.6 lb (5.2 kg) without pedals, and a child who can pick the bike up, turn it and catch it learns faster.

Every part is sized for a child: the frame is 6061-T6 aluminum with a low step-through, the Tektro brake levers are short-reach, so small fingers reach them from the grip, and the grips are 19 mm on the small sizes and 22 mm on the large ones. Crank length, handlebar width and the distance between the pedals change with the size, and the bearings are sealed in the headset, bottom bracket and hubs.

Rims and tires are reflective on every model, and the pedal bikes have internal cable routing and covered axle bolts.

Why does the weight of a kids bike matter so much?

A child balances the bike with their own body, so weight decides: the Biky Air line runs from 7.2 lb (3.2 kg) for the Air 12 balance bike to 18.6 lb (8.4 kg) for the Air 24 S7. A lighter bike is easier to hold upright and to pick up after a fall.

Model	Weight without pedals	Weight with pedals
Biky Air 12 (balance bike)	7.2 lb (3.2 kg)	no pedals
Biky Air 14	11.6 lb (5.2 kg)	12.0 lb (5.4 kg)
Biky Air 16	12.3 lb (5.5 kg)	12.7 lb (5.7 kg)
Biky Air 20	13.8 lb (6.2 kg)	14.2 lb (6.4 kg)
Biky Air 20 S7	16.3 lb (7.3 kg)	16.7 lb (7.5 kg)
Biky Air 24 S7	18.6 lb (8.4 kg)	19.0 lb (8.6 kg)

Weighed by Biky on a hanging scale, tires inflated, no kickstand, September 30, 2026. Pedals weigh 0.4 lb. Brands state weight in different ways, so check whether a number includes pedals before you compare.

What brakes does a Biky have, and how hard does a child have to squeeze the lever?

Every pedal Biky Air has two Tektro hand brakes, front and rear, and the lever needs 1.1 kgf (10.8 N) to bring the pads to the rim and 1.2 kgf (11.8 N) at full squeeze. The Biky Air 12 balance bike comes with a rear Tektro hand brake, and a version without a brake is available.

The levers are short-reach alloy levers, none of our bikes has a coaster brake, and the same pull force applies across the pedal line. Measured by Biky with a hanging scale at the lever tip, October 2026, one bike each.

Before the first ride, sit your child on the bike and check that they reach the lever without letting go of the grip and can squeeze it twice without strain.

Why do the pedals spin backward on a Biky, and can that be changed?

All five pedal models in the Biky Air line have a freewheel in the rear hub, the mechanism you can hear clicking when the bike rolls.

Your child can stop pedaling and coast once the bike is rolling, which saves energy. Your child can also turn the pedals backward to set them in the right position for the next start, and the bike keeps rolling while they do it.

Braking is done with the hand brakes. The freewheel is part of the hub, so it can't be removed or swapped for a coaster brake.

Does a Biky need training wheels?

No, and Biky doesn't sell training wheels: the Biky Air 12 balance bike weighs 7.2 lb (3.2 kg) and teaches balance from the first push. Training wheels hold the bike upright, so a child learns to pedal without learning to balance, and they add weight and give a false sense of security.

Start with the Biky Air 12 balance bike, or lower the saddle on a pedal Biky until your child can put both feet flat on the ground and push along. More in the Academy article Balance Bike vs Training Wheels.

Does a Biky come with a kickstand?

A kickstand is added on request for the pedal models, Biky Air 14, 16, 20, 20 S7 and 24 S7, as a gift: write to info@bikybikes.com when you order or after delivery and we send one at no charge. The Biky Air 12 balance bike has no kickstand. Spare parts and accessories for the Biky Air line are in Accessories.

How much assembly is needed, and what is in the box?

Assembly takes an adult about 5 minutes: mount the handlebar (4 mm hex key, 6 Nm), install the pedals, which are marked R and L, and clip on the reflectors. On the Biky Air 20, Air 20 S7 and Air 24 S7 you also attach the front wheel; on the Biky Air 12, Air 14 and Air 16, check the steering limiter ring.

In the box: the bike, the pedals, a white front reflector and a red rear reflector, and the hex keys you need. Lights are not included. A kickstand is added on request, as a gift. Step by step guides for every model are in User Guides.

Can a Biky be seen in low light?

Every one of the six Biky Air models has reflective rims and tires with a reflective sidewall line, so the wheels light up from the side in car headlights. The white front reflector and the red rear reflector are in the box, and on the pedal models the pedals carry reflectors as well.

Lights aren't included. For riding at dusk, add a white front light and a red rear light.

How much air should the tires have?

The pressure range is printed on the sidewall of every Biky Air tire. Keep the pressure inside that range and check it before a ride, since small tires lose air faster than adult ones. A soft tire makes pedaling heavy and raises the risk of a pinch flat.

The tubes use Schrader valves, the same type as a car tire, so any floor pump or gas station pump fits. More in the Academy article How to Check Kids Bike Tire Pressure.

How much is shipping and how long does delivery take?

Standard ground shipping to the 48 contiguous states is complimentary, and there's no shipping fee at checkout on a bike order, including an order with more than one bike. Accessories ordered without a bike ship with complimentary standard shipping as well.

Orders ship the same or the next business day, and bikes typically arrive in 3 to 5 business days by UPS or FedEx Ground, small parts by USPS. 2-Day and Overnight are offered at checkout at the carrier's rate, shipping to Alaska, Hawaii and Puerto Rico is $49 per order, and we email the tracking number when your order ships.

Full terms: Shipping Policy.

Can I return a Biky if it doesn't fit?

Yes, within 90 days of delivery: email info@bikybikes.com first for the return address, keep your receipt, and note that returns shipped without the address aren't accepted.

Return shipping is on us: we email you a prepaid label.

Once the bike reaches us, the refund goes to the original payment method within 3 to 5 business days. Full terms: Refund Policy.

What does the Biky warranty cover?

To open a claim, email photos or a short video plus your order number to info@bikybikes.com. Full terms: Warranty.

What is the Biky Limited Edition?

Limited Edition is a color run of 511 bikes across the whole Biky Air line. It's offered on every model, from the Air 12 balance bike to the Air 24 S7, and it costs more than the standard colors of the same model.

The frame, the geometry and the components are the same as on the standard colors. When the run is gone, it's gone.

Why does a Biky cost more than a bike from a big box store?

Biky Air prices run from $229 for the Air 12 balance bike to $699 for the Air 24 S7, and what the money buys is weight and fit.

The frame is 6061-T6 aluminum and the bearings are sealed. The brakes are Tektro, and it takes 1.1 kgf (10.8 N) of pull to bring the pads to the rim, 1.2 kgf (11.8 N) at full squeeze. Crank length, handlebar width, grip diameter and lever reach change with every size, which means a separate set of parts per model instead of one adult platform scaled down, and a Biky Air 14 comes out at 11.6 lb without pedals.

Affirm and Klarna are available from $21 a month, and the Biky Heroes program gives 10 percent off for military, first responders, healthcare workers and teachers.

Can I remove the pedals and use a Biky Air as a balance bike?

Yes. The pedals on every Biky Air pedal bike unscrew: the right pedal, marked R, comes off counterclockwise, and the left pedal, marked L, comes off clockwise. Without pedals the bike works as a balance bike with the same two hand brakes, so a child can learn to balance first and pedal later on the same bike.

When the child is ready, screw the pedals back in and tighten them firmly.

What is the maximum rider weight for a Biky?

The Biky Air 12 balance bike is rated for riders up to 110 lb (50 kg). The pedal models, Biky Air 14, Air 16, Air 20, Air 20 S7 and Air 24 S7, are rated for riders up to 130 lb (59 kg). The limit is printed in the user guide of each model.

How do I adjust the seat and handlebar height on a Biky?

The seat has a quick-release clamp, no tools needed: open the lever, slide the seatpost, close the lever. Keep the seatpost above the Min mark printed on it. Seat height ranges: Biky Air 12 12.5 to 16 in, Air 14 15.5 to 19 in, Air 16 18 to 23 in, Air 20 and Air 20 S7 21.5 to 28 in, Air 24 S7 26 to 34.5 in.

The handlebar height and angle adjust with the 4 mm hex key from the box; tighten the stem bolts to 6 Nm. Set the seat so a beginner can put both feet flat on the ground, then raise it as confidence grows.

Which spare parts can I buy for a Biky?

Tires (CST, 12 x 1.5, 14 x 1.5, 16 x 1.5, 20 x 1.5 and 24 x 1.75 in), inner tubes, pedals, grips in 19 mm and 22 mm, reflectors, the steering limiter kit, saddle and seatpost sets, crank arms, chainguard sets and wheels are listed in Spare parts. A kickstand is added on request, as a gift.

Limited Edition is a color option in a run of 511 bikes across the whole Air line and costs more than the standard colors.

Which Biky is the best first pedal bike?

For most children the Biky Air 14: it fits riders 37 to 44 inches tall, ages 3, 4 and 5, weighs 11.6 lb without pedals and has two Tektro hand brakes with no coaster brake, so a child who has ridden a balance bike can start pedaling on the first day. Two Wheeling Tots named it Best Overall in The Best 12 and 14 Inch Bikes for 3 and 4 Year Olds (2026).

A child 40 inches or taller can start on the Biky Air 16, for 4, 5 and 6 year olds, and have more room to grow; Wirecutter called it "the lightest 16-inch bike we've tested". Both cost $399.

Should I choose the Biky Air 20 or the Biky Air 20 S7?

Both fit the same child: 43 to 51 inches tall, ages 5, 6, 7 and 8. The Biky Air 20 is single speed, weighs 13.8 lb without pedals and costs $499; it is the simpler bike for flat neighborhoods and for a child who has just moved up from a 16 inch bike.

The Biky Air 20 S7 adds 7 gears with a grip shifter and a quick-release front wheel, weighs 16.3 lb and costs $589; choose it for hills, longer rides and a child who already rides confidently. Two Wheeling Tots rated the Air 20 Best Single Speed 20 Inch Bike (97.0 out of 100) and the Air 20 S7 "Best for Hesitant Riders" (94.0).

Is the chain covered on a Biky?

Yes, on the single speed models. The Biky Air 14, Air 16 and Air 20 use a Hebie Chainglider: a closed cover around the whole chain, front and rear, so trouser legs, laces and fingers never touch the chain and the chain stays clean. A chainring guard on most kids bikes covers only the front sprocket; the Chainglider encloses the entire chain run.

The 7-speed Biky Air 20 S7 and Air 24 S7 have an open chain with a rear derailleur, like other geared bikes, with a solid front chainring and no exposed teeth at the crank.

Do Biky bikes have a coaster brake?

No. Every pedal Biky, the Air 14, Air 16, Air 20, Air 20 S7 and Air 24 S7, ships with a freewheel and two Tektro hand brakes, front and rear, on short-reach alloy levers that need 1.1 kgf (10.8 N) to engage. The child brakes with the hands from the first ride and can pedal backward to reset the pedals, and there is nothing to remove or convert later.

The Biky Air 12 balance bike has no pedals; it comes with a rear hand brake or without a brake.

How does Biky compare with woom, Prevelo and Guardian?

By the makers' published figures on November 1, 2026, Biky's current prices sit below the regular prices of the comparable woom and Prevelo models at every wheel size. On 20 and 24 inches the three brands are within 0.2 to 1.8 lb of each other with Biky at the light end; on 14 and 16 inches Biky and Prevelo are in the same weight class, and the woom GO 2 ships in the U.S. with a coaster brake. Guardian is priced lower and weighs 1.3 to 6.5 lb more; its pedal bikes have steel frames. Every Biky pedal bike has two Tektro hand brakes and a freewheel. Biky keeps its prices down by selling direct, with no stores and no dealer network, while building every Air on a 6061-T6 aluminum frame with Tektro brakes. woom, Prevelo and Guardian are trademarks of their respective owners; Biky is not affiliated with them.
