What to buy for ADHD 12 yr old boy in Yr7

[ImTryingImReallyTrying]

Please give me ideas, because when I ask him myself all I get is 'I dunno'

He loves gaming, tech, super cars, sports brands. With the gaming, he has everything. This has been covered over previous Xmases and birthdays. He also has a tablet, Nintendo Switch and echo dot.

As his main gift we're getting him a new bike, but even with that he can't tell us what kind bike he wants.

What are the cool kids playing with and wearing these days???

God I sound so old asking what the cool kids are after these days, but I am an older mum and genuinely feel like I'm not young enough to know what's 'in' now.

Could have written this myself - I have a Y7 12 year old son with ADHD who got a new bike for his birthday last month!
He's also just started getting into labels - previously everything was Nike but for his birthday he asked for a Ralph Lauren polo shirt and joggers.

How about a driving experience? They aren't all outrageously expensive. Mine got to drive a Maserati last yr and is the same age. He loved it.

Also thinking of getting some aftershave, new football boots and perhaps a mini fridge for his room.

If he's getting a bike does he need much more than the usual small gifts/stocking fillers like books, toiletries, socks, chocolates, small Lego sets, card games etc - or whatever he's into.

Last year my then 12 year old with adhd got

New ping pong rackets and case
Nice shower gel and perfume suitable for a teen
Lots of books for his kindle
Theraputty (though his younger brother adores the stuff and has taken it with permission)
Various fidget toys/stress balls
Money

Trainers
led lights for room
gaming chair

My Yr 7, 12 year old ADHD boy has asked for some nike trainers (a specific pair), nike tech hoodie, a new gaming keyboard, black crocs, new backpack for school, and an aftershave.
I am also going to get him a driving experience, nike socks, and hair products, we are also looking at a secondhand bike.
