The new HUP enduro: a youth MTB hardtail that climbs as well as it descends…

Lightweight, full-sized wheels, boost axles and enduro-focused geometry for youth riders age 6+ creating a unique hardtail that changes the game for youth and small adult riders, here's why;

Progressive Geo: super-low standover, youth top-tubes, slack 65º fork, up to 120mm forks for riders 120cm+
Full Size Wheels: choose 27.5"or 29er (world's smallest) or Mixed - in Aluminium or Carbon, up to 2.4" tyres
Still Lightweight: strong, double-butted 6061 in 3 sizes for youth/small adult riders and as light as 9.5kg!
Custom Components: short cranks, dropper posts, big gearing, hydraulic brakes (+ upgrade sizes as they grow)
Quality Throughout: only top brands including SRAM, FSA, Jagwire, Fulcrum, Rockshox, Manitou, Tekro & KMC
Build Flexibility: frame only, self-build bundles (with/without wheels/fork) or individual components or use your own parts

Lightweight and capable of even the most technical descents - but still happy to climb. Now they can roll over trouble, not into it, because trails are designed for adult size wheels - not 24” wheels. That’s why our test squad love them!

Low maintenance design with full length outer (internally run) cabling, including option to fit a dropper post. Child-specific ‘progressive’ geometry with a 65 degree fork angle (controlled descending), proportional top-tube and short stems for correct fit. Super-low standover/low stack giving small riders the space to move, dropper post ready for tiny legs from just 60cm inside leg.

Big wheels on clever geometry and correct components, the advantages of running 27.5” or 29” for riders more typically on 20”/24”/26” wheels are very real. Roll over trouble, not into it. Trails are designed for adult size wheels, not 24” wheels. Parents also benefit from component sharing (life is simple with everyone on the same size wheels!) and accessing quality upgrades from adult bikes like soft compound, lightweight enduro tyres or carbon wheelsets.

Riders sizes (L to R): 125cm on 13", 139cm on 13", 142cm on 13", 156cm on 15.5", 161cm on 15.5" & 166cm on 17.5"

With 3 sizes of frame covering riders from approx 120cm (57cm inside leg on 27.5" wheels) up to approx 175cm tall, you can move their components to a larger frame as they grow, just like all our HUP bikes. You can even bias the geometry to suit your favoured riding: XC (longer stem, narrower bars, smaller brakes, fixed seat post, XC tyres) or Enduro: (shorter stem, wider bars, larger brakes, dropper post, enduro tyres).

Included with this frame: frame, headset, mech hanger, thru-axle & cable fittings.
Self-build bundles or components available separately. HUP frames are handmade/painted in Taiwan. Headset requires cups to be pressed into headtube. Frame protection tape is highly recommended.
