Kids MTB Trousers

Made for young riders who like to push it – from trail centres and bike parks to the pump track. Our Kids MTB Trousers are tough, breathable and built to move, with removable hip padding for extra cushioning on the trail.

The hard-wearing fabric keeps its shape wash after wash, and the breathable build keeps riders comfortable on long climbs and fast descents.

The fit is the clever bit: an adjustable waist plus a choice of three leg lengths, so they fit properly now and keep fitting as your rider grows.

Size Guide

Waist (inches)	Shortest leg (inches)	Mid leg (inches)	Longest leg (inches)
18"	25.5	26.5	28
20"	26.5	27.5	29
22"	27.5	28.5	30
24"	29.5	30.5	32
26"	31.5	32.5	34
28"	33.5	35	36

Choose by waist size, then set the leg to one of three lengths. How to check: measure around your child's waist where the trousers will sit and compare it with the waist sizes above.

Protection reduces the risk of injury but cannot prevent all injuries. Always ride with a correctly fitted helmet.

Trousers

Amazing. All fits perfectly. Can rest easy knowing my boy is safe when racing

Amazing product!

My youngest has worn these a few times now for both MTB and race BMX. Padding on them is far greater than any others we've ever had. My kids have always struggled to undo their biking trousers with the plastic ratchet type fastening, but my 5 year old can do these with ease.
Love that they will adjust and grow with the kids. Added bonus that they look great too!
Can't wait for more stock to get some for my oldest too!

The best by a mile

We have a pair of these trousers for each of our girls (4 and 7) and can say they are simply brilliant. Durable, comfortable and fit perfectly. The fact that they adjust as the girls grow is pure genius and Emma’s we no longer fear the inevitable growth spurt just as we’ve bought them new gear. Would not hesitate to recommend for any little rippers!

The best bike trousers

I love these bike trousers! The quality is great and the trousers are very stable. Especially in bike parks and at races, they have protected me very well a few times!
So if you are planning exciting experiences with your bike, these trousers are your best companion!

Brilliant, grandkids love them

Fantastic trousers. Grandkids love them, great fit, comfortable and protection in the right places.
Hardly taken them off since they got them for Christmas!

Awesome kit!

Ordered the padded hoodie and mtb trousers for my girl. They look great and certainly feel good quality, with lots of pads and protection. Will be ordering a second set for my son. 👍🏽
