Grewbik Ember - Adjustable Children's Bike

One bike. Five sizes. Total freedom.
Grewbik is the only children's bike your child needs from 2 to 11 years old. With a smart adjustable frame, the bike grows with the child - you only change the wheel size, not the entire bike.

Made of aluminum for low weight and high durability, with ergonomics, safety and design in focus. Grewbik gives children of all ages a safe and fun cycling experience - and parents a smarter investment.

Features:

- Adjustable frame - five sizes in one bike

- Choose between wheel sizes: 12”, 14”, 16”, 18” and 20”

- Low weight thanks to strong aluminum frame

- Comfortable components adapted for growing children

- Designed and developed in Sweden

Tip:

The bike comes with a set of wheels in your chosen starting size. As your child grows, you can easily switch to a larger set of wheels (sold separately) and customize the bike in just a few minutes. It's a smart, sustainable and fun way for both children and parents to keep up with their development - without having to buy a whole new bike.
