MERIDA eONE-Eighty 400

The MERIDA eONE-Eighty 400 is Merida’s highly effective entry level 180mm travel eMTB. This beauty guarantees immense fun and delivers exceptional performance.

The eOne-Eighty is for the heavy hitters, bike park senders and big mountain brawlers. 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 85Nm of Bosch CX power. Furthermore, the battery is removeable for easy charging off the bike. It’s MERIDA’s longest travel e-bike ever, with 180mm of suspension at either end on a robust aluminium frame. Add coil shock compatibility, mullet only setup plus a whole host of other features and getting rowdy is where the eOne-Eighty starts, not finishes.

There’s a serious amount of range on offer too, thanks to the new 600Wh battery and the option to add a 250Wh Bosch range extender. You can easily remove the battery for off-bike charging or replacement on a really big ride.

Bosch’s Purion 200 display provides all the necessary rider information at the touch of a button.

Perfect geometry. Perfect lines. A great set of components take the eONE-Eighty to dizzy heights. Designed for full off road, this gem of an eMTB provides serious performance.

Perfect Balance, Extraordinary Performance, Great Components

The SR Suntour Aion 38X Air forks are ultra responsive and highly capable. As a result, they gobble up almost anything thrown in front of them. Offering a huge 180mm of travel, the Aion’s are a great entry level fork with superb performance. On the rear is a very nice SR Suntour TRIAIR2 shock. Featuring a rebound and compression damper adjuster the TRIAIR2 offers huge flexibility and fine tuning. In addition, the piggyback comprises an air-backed internal floating piston system (IFP) which is easy to adjust.

Gearing on the MERIDA eONE-Eighty 400 is slick. A Shimano Cues 9-speed and 11-46T cassette work in perfect harmony. A Merida Team TR II tubeless ready wheelset prove tough, stable and reliable. Maxxis Assegai 29×2.5″ tyres are on the front, whilst the rear is taken care of by a Maxxis Minion DHR II 27.5×2.4″. Consequently, the result is superb maneuverability and grip, all in one. Shimano Shimano TC500 hubs finish off a high performing wheelset. Braking is highly effective, thanks to the Tektro Gemini M535 4-piston hydraulics, front and rear. They’re hugely responsive and offer both powerful and controllable braking.

Unlike many eMTBs, the MERIDA eONE-Eighty 400 comes with lights on both front and rear. Worthy of note is the Lezyne Hecto lamp on the front which strongly illuminates the path ahead in low light conditions.

A Merida Expert TR II dropper seatpost operates smoothly and precisely.

Enviable Aesthetics, Smooth Lines

The aesthetics of the MERIDA eONE-Eighty 400 are enviable. This is one seriously good looking eMTB! Internal cable routing has been perfected thanks to Merida’s ‘Smart Entry’ approach. Cables are routed internally, with clamping under tension. There’s no rattles or noise!

Ideal for those on a tight budget, the MERIDA eONE-Eighty 400 delivers above and beyond where others struggle.

How do I measure my height?

With your shoes off, stand upright against a wall, with your shoulders back and legs together. Use a pencil to make a small mark on the wall above your head (make sure you hold the pencil parallel to the floor). Then measure from the floor to your mark, in centimetres or feet and inches.

How do I measure my inside leg length?

With your shoes off, stand upright with your back against a wall. Place a book/ruler between your legs, level with your crotch. Then measure from the floor to the top of the book/ruler, in centimetres or feet and inches (it’s easier if a friend helps).

Q & A

Do all brands of ebike use the same unit of measurement?

No. Most brands show sizing in centimetres, however some use a S/M/L system, and others use inches. The table above includes all of these variations to help you find the right size.

Which size should I go for if I'm in between those listed?

If your measurements suggest that you have a choice of two different sizes, then in the end it’s a personal choice. Here are some rules of thumb to consider: Touring/Trekking ebikes - choose the smaller size. It is possible to make a smaller frame bigger (for example, by raising the saddle or fitting a longer the stem), whereas if the frame itself is too big for you, it’s likely to be less comfortable and won't feel right. eMTBs - choose the larger size. You’ll find an eMTB with a slightly larger frame easier to handle than one that feels cramped. You can always fit a shorter stem if necessary to reduce the reach to the handlebars.

How are ebike frame sizes measured?

An electric bike’s frame size is calculated by measuring the distance from the top of the seat tube (where the seat post inserts), to the centre of the front chainring. Sizing Guide
