2025 Merida eOne-Eighty 400 eMTB in Black

The eONE-EIGHTY 400 might be our entry-level big-hitting e-MTB, but we've made a bike ready for the rough stuff at a budget-friendly price. Suntour's Aion 38X fork and TRIAIR2 shock serve up 180mm of sorted suspension, and our tough aluminium frame features mixed-size wheels to keep things fun and flickable. Shimano's solid CUES drivetrain offers flawless shifting under pressure, while four-piston brakes will stop you in good order.

Calling all heavy hitters, bike park senders and big mountain brawlers, this one’s for you. The new eONE-EIGHTY has landed, and it’s ready to ride the biggest lines and burliest tracks - and you can say goodbye to waiting in the uplift queue because it can rip and repeat all day long thanks to a 600Wh battery and Bosch CX power.

Get Rowdy on Repeat
It’s our longest travel e-bike ever, with 180mm of suspension at either end on a robust aluminium frame with a new suspension platform that builds on our award-winning FAST kinematic from the eONE-SIXTY and sends it to new heights. Add in coil shock compatibility, mixed-wheel size only setup, plus a whole host of other features and getting rowdy is where the eONE-EIGHTY starts, not finishes. Up or down, it’s ready to rock.

Bosch Performance
It’s also our first e-MTB to use the Bosch Performance Line CX drive unit, which offers powerful assistance and silent performance with 85Nm on tap. There’s a serious amount of range on offer too, thanks to the new 600Wh battery - plus the option of a 250Wh range extender.

Fidlock Cover
You can easily remove the battery for off-bike charging or replacement on a really big ride, plus we’ve also got a new cover that protects from dirt, impacts and moisture - and it holds itself in place with the magic of Fidlock magnets.


It’s rated for Category 5 riding too, so you can get stuck into as many bike park laps or downhill tracks as you like without voiding the 5-year warranty

Agilometer Sizing
A 30-230 mm travel adjustable dropper post (excluding the eOne-Eighty 500 & 400), combined with a low stand-over height allows riders to select a bike size based on their preferences rather than their height.
Short, Mid and Long sizing reflects the proven Agilometer sizing system, accommodating all needs from long-reach stability to shorter-reach manoeuvrability or more upright riding comfort.
