€99.95, down from €119.95. The number that matters more is four, as in years, because the only argument for spending Mini Micro money on a one year old is that it does not stay a scooter for a one year old.

The three stages are real rather than marketing

It starts as a ride-on with a seat and a handle at the back, for a child who can sit up and hold on but has no useful opinion about where they are going. Then the handle comes off and the seat drops to its lower setting, and they push themselves along with their feet, which is where balance actually starts. Then the seat comes off entirely and it is a Mini Micro: lean to steer, bar out to 67cm, the same machine sold on its own for €79.95.

Most convertible children’s products fail because one of the modes is bad, usually the last one. That is not the case here, and it is the reason the maths works at all.

What the maths actually looks like

Say the child gets it at fourteen months and rides it as a standing scooter until they start school. The parent-pushed phase is the shortest by some way. Six months is typical, less if they walk early, because a toddler who can walk wants to push their own scooter and will fight you about it. The seated phase runs a year or so. The standing phase is most of the four years.

So you are paying €20 over the plain Mini for two transitional modes, one of which is brief. If this is a second or third child and there is already a Mini in the house, that €20 buys very little. If it is a first child and the realistic alternative is a ride-on now and a scooter in two years, the 3in1 is comfortably cheaper and takes up less room in the hall.

The 50kg limit will never be what ends it. Size will, somewhere around five.

Small things worth knowing

The deck is made from recycled fishing nets, which is a nice detail rather than a reason to buy. What matters day to day is that it is stiff and quiet.

More parts means more parts to lose. The seat and the push-handle both come off, and each is worthless without the other if you are passing it on. Put them in the attic together in one bag, labelled, on the day you take them off.

Who should not buy it

Anyone whose child is already two and a half. You would be paying for two stages you have missed. Buy the standard Mini Micro, or the Deluxe LED if light-up wheels will get them out the door.

Skip it too if you want something for real distance on a footpath, or if your toddler is heavy-footed and hard on things. This is a light scooter designed to be light, and it rewards a household that looks after it.

Check the colourway before you order as well. The light-up wheels are a separate model and children notice.
