The Trek Marlin+ 8 2026 is an electric mountain bike built for trail riding rather than commuting. The Bosch Active Line Plus motor gives you smooth, natural assist that doesn't take over — it helps you climb harder trails and ride further, but it still feels like you're doing the riding. 27.5” wheels, Shimano Deore 12-speed and a dropper post make this a trail-capable package, not just a mountain-shaped e-bike.
WHO THIS BIKE SUITS
You want to tackle trails you'd normally find too demanding, without committing to a full e-MTB rig.
You're riding with faster companions and want to keep up on the climbs without burning out.
You want genuine trail capability alongside the reliability and support of a Bosch motor system.
You want an e-MTB that still feels like a bike — not something that does the riding for you.
IF YOU'RE LOOKING FOR SOMETHING DIFFERENT
If you want more suspension travel and a full-power motor for aggressive trail riding, the Rail+ range is worth a look.
If you don't need motor assist and want to keep things simple, the Marlin 7 covers similar spec ground.
WHERE IT SITS IN THE RANGE
The Marlin+ 8 sits at the accessible end of ARN's e-MTB range — Bosch-powered, trail-ready, and built around the proven Marlin platform.
HOW IT RIDES
Motor
The Bosch Active Line Plus delivers 50Nm of torque — enough to take the sting out of steep climbs without feeling artificial on flatter trails.
Drivetrain
Shimano Deore 12-speed is proper trail-spec — wide range, reliable under load, and well-supported for servicing.
Tyres
Bontrager Gunnison Pro XR tubeless-ready tyres — dual compound, aramid bead, 60tpi. Genuinely good rubber, not budget filler.
THE FINAL WORD
The Trek Marlin+ 8 2026 is the e-MTB we'd recommend to riders who want trail capability with motor assist, without the weight and complexity of a full-power enduro bike. Come in and talk to us, or get in touch and we'll walk you through the options.
