Pre-order your children's bike - pay only 20% today

Grewbik is an adjustable and modular children's bike that grows with your child - from 2 to 12 years old. Instead of buying several different bikes during their growth, you can easily change the wheel size - from 12” up to 20” - on one and the same frame.

The bike is cleverly designed to adjust to the child's height and age. It is durable, ergonomic and designed to solve the common problem of children quickly outgrowing their bikes.

When you pre-order, you can choose to pay the full amount immediately or pay only 20% as a down payment today. The remaining amount (80%) is paid before delivery between April - June 2026.
