FirstBike Adapter for lowering the seat

The adapter lowers the height of the seat by 4 cm, a frequently used addition for children aged 2 years to comfortably reach the floor with both feet with their current height and the lowest seat setting. Thanks to the adapter, children from 87 cm tall can ride the models with inflatable tyres, and from 84 cm tall on the Street PU model with fixed wheels. It can be easily mounted on the rear wheel of any model.
