Rent a Kids' Bike – Freedom on Two Wheels, With Total Flexibility

It starts with a balance bike and a dose of curiosity. Eventually, your child stands there and asks, “Can I ride a bike now?” Their very first bike is a real highlight—for kids and parents alike. It means adventure, independence, and that special moment when wobbly steps suddenly turn into confident turns. As your child sets off with sparkling eyes, your heart beats a little faster.

Some kids take off at three years old, others take their time. Both are wonderful. What matters isn’t how early or how far, but that the joy of riding is the focus. Learning to ride a bike isn’t a competition, but a real family experience—full of small successes and big emotions.

Why a rented children’s bike is the best choice for you

Kids grow. Fast. One minute the bike fits perfectly—and suddenly their legs are too long, the seat is too low, and the bike sits unused in the corner. Many families know the challenge that kids’ bikes often only fit for a limited time. Renting offers a flexible alternative here.

A rented bike adapts to your family’s daily life—not the other way around. And it comes with plenty of benefits:

  • Always the right size – just upgrade to the next size as your child grows
  • No risk of a bad buy—you can test what really fits
  • Stay flexible—ideal for vacations, growth spurts, or younger siblings
  • High-quality brands to choose from – e.g., Woom, Puky, KUbikes, or Academy Bikes
  • Sustainable & hassle-free – easy returns after the rental period
  • Parent-friendly – affordable, transparent, and easy to plan

Balance bike or bicycle? Here’s how to find the perfect start

For many children, the adventure on two wheels begins with a balance bike. Lightweight, agile, and intuitive—even the youngest children can learn to balance in a playful way. Those who start riding a balance bike early often transition directly to their first bike, without training wheels.

Whether a balance bike or a regular bike—both have their place. Here’s a quick comparison:

Balance bike Bicycle
Ideal from about 1.5 years old usually suitable from about 3–4 years
Promotes balance and body awareness promotes coordination & motor skills
No pedals – focus on balance With pedals, brakes, and training wheels if needed
often a transition to a bike without training wheels more technical, but also more fun

Some kids take off right away at age three, while others love their balance bike until age five. Training wheels are totally fine, too—as long as they provide safety and don’t take away from the fun of riding. What’s important is that the bike matches your child’s developmental stage and that they’re eager to give it a try. Everything is allowed, nothing is required—and fun always comes first.

What bike size is right for what age? Our overview

Children’s bikes come in various wheel sizes—but which one actually suits which age? Body height plays a crucial role here. Because a bike that’s too big or too small isn’t fun and can even be unsafe.

To help you keep track, we’ve put together a simple guide—including model examples that you can rent directly from StrollMe:

Child’s age Height Recommended bike size Suitable type Available models
1.5 – 2.5 years approx. 80 – 90 cm 10″ – 12″ Balance bike Woom GO 1, Woom GO 1 PLUS, KUbikes 12 superlight, Puky LR Light
2.5–4 years approx. 90–100 cm 12″ Balance bike or first bike Woom GO 2, Academy Grade 1, Cube Cubie 120
4–5 years approx. 100–110 cm 14″ – 16″ Children’s bike with child-friendly geometry Woom GO 3, Puky LS-Pro 16, Cube Cubie 160
5–6 years approx. 110–120 cm 16″ – 18″ Children's bike with hand brakes Woom GO 4, Academy Grade 3, KUbikes 16

💡 Tip: When adjusting the saddle and handlebars, make sure your child can comfortably reach the ground with both feet. This ensures safety, confidence, and above all: lots of riding fun.

Ergonomics & Safety – What to Look For

A good kids’ bike needs to do more than just look cute. It should fit your child’s height and strength—and be intuitive to use. Because if a child feels unsafe on a bike, they’ll quickly lose interest in riding.

To prevent that from happening, at StrollMe we focus on child-friendly models that excel in terms of ergonomics and safety. Every bike you can rent from us meets these requirements:

  • Low step-through – makes getting on and off easier
  • Narrow pedal spacing – ensures a natural leg movement
  • Brake levers for small hands – easy to reach and operate
  • Lightweight – for independent riding, stopping, and braking
  • Adjustable saddle and handlebars – grow flexibly with your child

When it comes to safety, StrollMe bikes are also top-notch: with sturdy frames, brakes that are easy to control, non-slip grips, and highly visible reflectors – for a safe riding experience on every outing.

💡 Tip: Your child should not only be able to ride the bike, but also push it, brake, and balance it. This promotes safety—and builds self-confidence from the very start.

More than just a bike – accessories that think ahead

A road-safe children’s bike needs more than just two wheels. Especially in traffic, visibility, protection, and control are crucial—and the right accessories help improve exactly that.

For greater visibility & safety:

  • Bike helmet – the most important accessory. It protects in the event of a fall and ensures peace of mind on every ride —> See our helmets
  • Reflectors & spoke lights – standard on all bikes from our brands like Woom, Puky, or Cube – for better visibility at dusk and in the dark
  • Bell – alerts others to your child’s presence early on (e.g., Woom Bell)
  • Light set – especially useful during the darker months or for winter commutes to school (e.g., Woom light)

For greater everyday practicality:

  • Fenders – provide reliable protection against splashing water (e.g., Woom fenders)
  • Luggage rack – ideal for backpacks, small bags, or treasures from the playground
  • Air pump – handy for home or on the go
  • Bike lock – secures the bike when stopping at daycare, in the park, or while shopping

At StrollMe, you can rent accessories flexibly—exactly when you really need them. Whether for a specific period, a trip, or the start of fall: you stay flexible, save space, and go easy on your budget.

For safety and hygiene reasons, you should buy a helmet and a pump. Everything else you can rent with peace of mind—high-quality, tested, and compatible with your bike.

FAQ – the most common questions about children’s bikes

What bike size is right for what age?

Body height matters:

12" from approx. 90 cm, 14–16" from approx. 100 cm, 20" from approx. 115 cm. The seat height is correct when your child can reach the ground with both feet.

At what age can children start learning to ride a bike?

Many children get their first bike between the ages of 3 and 5 – balance, coordination, and a desire to ride are key.

Balance bike or regular bike – which is better for beginners?

Balance bikes are ideal starting around 1.5 years old. Once a child is confident on a balance bike, they can often transition directly to a regular bike—usually without training wheels.

What makes a child’s bike safe for traffic?

Important features include: reflectors, working brakes, a bell, a light for riding in the dark – and a helmet that fits well.

Is a helmet required?

No, but it is strongly recommended. A properly fitting children’s helmet provides protection in the event of a fall and should be part of the standard equipment.

How quickly does a children’s bike become too small?

Children often grow faster than you think—a bike usually only fits for 1 to 2 years. If you stay flexible and, for example, rent a bike, you can easily switch to the next size as soon as the old bike no longer fits.

Which is better: hand brakes or coaster brakes?

Many children find it easier to use coaster brakes at first. Hand brakes offer more control later on—it’s best to combine both.

What accessories are useful?

For example: helmet, lights, fenders, lock, bell, and rack. What’s really needed depends on how the bike will be used.

How do I know if the bike really fits?

The bike fits if your child can get on and off, brake, and stand safely on their own—without tipping over.

Is my child allowed to ride a bike on the sidewalk?

Yes, it’s mandatory until their 8th birthday. Between ages 8 and 10, the sidewalk is permitted; from age 10 onward, the bike path must be used.
