DD2 needs a pedal bike, she's grown out of her balance bike.
DD1 is still fine on her first pedal bike and she's got a scooter that should last ages, it's got an extendable handle and 50kg weight limit.
They're 4yo and 6yo so don't necessarily know what stuff costs.
Cheap 2 wheel scooter? Her current one is 3 wheel (double wheel at front) but you can only ride one at a time and I don't like buying duplicate items.
No technology, screens turn her into the devil child.
