Olakids Girls' Bike, Steel Frame

For a child just starting to ride, this mermaid-themed bike combines training wheels with features meant to make early practice more manageable. The training wheels are detachable, so they can be removed as riding confidence grows.

A basket and handlebar streamers give it a playful look, while the basket can hold small ride-along items such as a snack or toy. Seat and handlebar height adjust, allowing some changes as a child grows.

If you prioritize beginner-friendly support and a themed design, this setup makes sense, if you prefer a simpler bike without a basket, streamers, or training wheels, those extras may not be useful to you.

Where it shines

The bike is offered in 12-, 14-, 16-, 18-, and 20-inch sizes. Its adjustable seat and handlebar can help tailor the riding position, and the removable training wheels offer a way to start with extra support before moving toward two-wheel practice. The listing does not provide a child-fit chart, though, so choosing a size by wheel options alone is difficult, use the child’s measurements rather than guessing without that measurement.

The dual-brake setup includes a hand brake and a rear coaster brake. That gives a young rider two ways to slow down, but a child who is new to biking may need practice understanding how each brake works. An enclosed chain guard, a bell on the right handle, and wide pneumatic rubber tires round out the practical details. For example, on a short practice ride in a park, the basket can carry a toy while the bell gives the rider a way to signal nearby people.

The steel frame, soft foam seat, and easy-grip handles are intended for everyday beginner rides. The seller also states that the bike meets US CPSIA and ASTM requirements and is free of several listed materials, including BPA, PVC, phthalates, lead, latex, and formaldehyde. Those are product claims, not a substitute for checking the fit and supervising a new rider.

What to know

The bike arrives 85% assembled, with instructions and required tools included. The listing estimates about 15 minutes for installation, but that is a stated estimate, not a guarantee, assembly time can depend on the person putting it together. Make sure the brakes and other assembled parts are set up correctly before a child rides.

You’ll appreciate it if you want a beginner bike with removable training wheels and a design that feels more personal than a plain, basic model. The adjustable parts are useful, but no adjustment ranges or child size guidance are provided. It’s not for you if you need a confirmed fit from the listing alone, or if the child is ready for a bike without training wheels and themed accessories.

Best use cases

This setup is aimed at supervised practice and casual rides for a child learning the basics. The basket suits lightweight items such as a snack or toy, the product details do not specify its capacity, so it should not be treated as cargo storage. The pneumatic tires are described as suitable for different terrains, but no tire measurements or surface-specific guidance are given. For demanding riding or a precisely tailored fit, a bike with clearer sizing information may be the more practical approach.

Final verdict

Choose this Olakids bike if the child wants the mermaid styling and would benefit from training wheels, a bell, and an adjustable seat and handlebar. Its main compromise is limited sizing detail: the wheel options are listed, but there is no fit chart to help match them to a rider. If you can establish the right size and are comfortable checking the assembly, it offers a feature-filled starting point, if sizing certainty or a pared-back design matters more, keep looking.
