Little legs need little, lightweight bikes!
For this very reason, we recommend Frog Bikes to all our small customers (and their parents!) - child specific design, easier to learn on and more fun to ride.
If your little 'un wants to ride the same as Mum or Dad, then the Cube Kid range might be just the ticket. If we don't have the Cube bike you're looking for in the shop, if it's available from Cube we can normally have it here for you in 4-5 days.
