The MERIDA eONE-EIGHTY is extremely versatile, and an optimal choice for riders who want to tackle long rides and steep, rough trails without relying on a lift.
E-Mountainbike Magazine logoE-Mountainbike Magazine
Merida’s new eOne-Eighty might stray a long way from the brand’s XC roots, but this top-level 900 aluminium machine munches everything in its path and packs a lighter touch that defies its hefty payload.

Merida eOne-Eighty 900 e-MTB review

May 2025

The Merida eOne-Eighty is a full-fat, full-weight e-MTB with 180mm travel and an 800Wh battery. Its sole purpose is to be a hard-charging monster truck of a bike that can lap bike parks all day. Whilst the large battery allows for some big days and the weight gives a super stable ride, it also manages to disguise the heft with some clever geometry and its mullet wheel set-up. With a good spec and some well-tuned suspension, this bike remains unflustered in all but the tightest of tech.

Bosch-powered Merida is here – the eOne-Sixty SL and eOne-Eighty intro and test

Oct 2024 · Knut Nes

Merida has used Bosch-motors for years, but not on the emtbs. The full suspension eOne-Forty and eOne-Sixty always had, and still have Shimano motors. But it’s nice to have options. If you’re set on buying a Bosch Powered emtb, you can now add...

Merida’s new eOne-Eighty is the most capable long-travel e-bike I’ve ever tested, at 27kg I’d hate to have to muscle it over a gate though - MBR

Oct 2024 · Mick Kirkman

Merida started down electric avenue early, it developed sweet riding e-bikes before many other brands even got switched on to the concept. This helped the Taiwanese behemoth tie in with Shimano and get details like geometry, sizing and suspension performance dialled early. The original eOne-Sixty is testament to this, launched in 2016 it became a shredder’s bike of choice before there really was much choice in the slacker, rowdier end of the market. A fixture in the Dirt 100, the downhiller’s bible bike list, the e-160 became one of the best electric mountain bikes of its generation. Merida and Shimano’s successful partnership has lasted the best part of a decade with every mid-motor eeb sporting Japanese-designed power, right up to the latest EP801. Think Merida, think Shimano… until now. Merida eOne-Eighty 900 need to know Merida’s longest ever travel e-bike gets the latest Bosch CX motor Part of a new Merida electric line up that sees the brand add Bosch drive bikes to its Shimano-powered range New range uses a new shock layout and suspension platform to differentiate from older e-bikes Aluminium-only frame comes with 800Wh removable battery that’s expandable to over 1000Wh with Bosch’s range extender Mixed mullet wheels as standard and five size options, each with size-specific kinematics Prices range from £4,900 to £7,500 Bosch in, Shimano out This brand-new Merida eOne-Eighty, and separately a carbon fibre eOneSixty SL model you can read about here, both plug into the latest Bosch motor. The big eOne-Eighty uses the recently launched and much hyped CX drive unit; and the shorter travel SL gets the lighter, less powerful, SX. With this pair and the Shimano-powered e-160 launched earlier in the year, the brand now has all electric bases covered. Want a lighter, carbon-framed (fixed-battery) frame? Check out the carbon e-160 or new e-160 SL. Need a chunkier alloy-framed removable-battery model? Go for the Merida eOne-Sixty or now the new eOne-Eighty. Across the Merida electric range, travel options and intentions stretch from trail to enduro to full-on gravity machines. Merida eOne-Eighty 900 design and geometry The heart of the eOne-Eighty is its new Bosch CX gen 5 motor. It might not claim any bold new statistics over its predecessor’s 600W peak power or 85Nm, but it has clearly had plenty more work done than just a nip and tuck to save 100g. New CX immediately feels way more refined, rides much quieter and delivers its power much more cleverly. And because it now mounts with the same two bolts as the Bosch SX motor, brands like Merida have had to build all-new frames to accommodate it. The ironically named eOne-Eighty LITE frame is aluminium only and, like Canyon’s Torque:On and the Whyte E-180 Worx MX one of the few e-bikes with full Cat 5 DH rating. That means a five year warranty and a bombproof build. I chucked it down plenty of rocks in Spain, it’s designed to tackle bike parks, DH tracks and being ridden by massive riders in all weathers with …Continue reading »

Highs
  • • Wears its weight well for a 27kg bike, MX wheels add agility

  • • Suspension balance, comfort and tracking are excellent

  • • Gets Bosch’s new CX motor and latest generation 800Wh battery

  • • Built like a tank (looks like one, too)

Lows
  • • Weight is a hindrance on mellow or flatter trails or when hefting the bike

  • • The new wider rocker link design repeatedly knocked my knees

  • • Not as elegant as some carbon e-bikes
