Boss Stealth 24 Mountain Bike

The Stealth is the best-selling bike in the Boss range, and this is the 24" version for older children and younger teenagers. Front and rear suspension, disc brakes at both ends, mudguards fitted and a full 18-speed drivetrain — properly equipped for real trail riding.

Who it fits

Suitable for an inside leg measurement of 65–74cm (25–29"). Measure from the floor to the crotch with shoes off — it's a far better guide than age or height. Below that range, the Stealth 20 is the size down; above it, the Stealth 26 is the adult-sized version.

What you're getting

• Gears: 18 speed Shimano — a wide spread for climbing and descending
• Brakes: front and rear Clarks disc brakes, which keep working when the rims are wet or muddy
• Suspension: front fork always active, plus an adjustable rear unit so you can dial in how much give it has
• Wheels and tyres: deep section rims, strong disc hubs and grippy 1.95" off-road tyres
• Fitted as standard: front and rear mudguards, full-colour saddle

Why we can price like this

We're an authorised Boss dealer — but we don't run a shop.

No showroom. No shop floor. No stock sitting in a warehouse depreciating. Your bike is picked and dispatched from the manufacturer's own facility and comes straight to your door.

A traditional bike shop has to cover premises, staff and stockholding before it makes a penny, and that has to come out of the ticket price. We don't carry those costs, so we're not asking you to pay for them.

What you don't lose: full manufacturer warranty, because we're an authorised dealer and not a grey importer. A real person to talk sizing through with before you order. And the option of a professional build so it arrives ready to ride.

Delivery and build

Free UK mainland delivery. Bikes ship boxed and part-assembled as standard. Add our professional build and safety check at checkout and a qualified mechanic assembles, adjusts and safety-checks the bike before it leaves — a real workshop job, and entirely optional. On a bike with disc brakes and suspension it's worth having done properly.

Klarna and Clearpay available on any order value.
