Merida eONE-SIXTY 675

About the Merida eONE-SIXTY 675

Merida's eONE-SIXTY 675 lands squarely in the e-enduro sweet spot - long travel, big battery, aluminium toughness - and wraps it all in a package that punches well above its price point. The 2025 model refines the fourth-generation LITE aluminium chassis with P-Flex stays that ditch the traditional rear pivot for controlled flex, shaving grams and complexity whilst keeping the suspension supple and predictable. Shimano's EP801 motor delivers 85 newton-metres through a 750-watt-hour Trendpower battery, and if that's not enough, slot in the optional 360-watt-hour range extender and you're looking at all-day epics without the range anxiety. It's a bike built to handle demanding trails, technical climbs, and rowdy descents without asking you to remortgage for carbon.

The geometry leans enduro: a 64.4-degree head angle, steep 78.4-degree seat tube, and reach figures that stretch from 419 millimetres in XShort to 499 in XLong. That translates to a planted, confidence-inspiring stance when the trail tilts down, yet the motor's assist carryover firmware keeps momentum flowing through technical climbs where lesser e-bikes bog. Marzocchi Z1 and Bomber Air suspension - 170 millimetres up front, 174 at the rear - soak up the rough stuff with a control that belies their mid-tier billing, whilst Shimano Deore Linkglide gearing and four-piston brakes bring e-bike-specific durability to the party. Maxxis Assegai and Minion DHR II rubber, a travel-adjustable dropper, and integrated mini-fenders round out a spec sheet that's refreshingly complete rather than cynically stripped back.

This isn't a bike for riders chasing the lightest possible package or the snappiest trail manners. At around 25.6 kilograms for a mid-sized frame - before you add the extender - it's a heavyweight, and you'll feel that heft in tight, slow-speed switchbacks where steering takes a touch more input. But point it downhill, let the suspension breathe, and the 675 disguises its mass with poise and composure. It's the SUV of e-MTBs: capable, practical, and built to go the distance without drama.

Merida eONE-SIXTY 675 geometry

Reach-based sizing - Merida calls it the Agilometer system - lets you choose your frame length by preference rather than inseam alone, so shorter riders chasing stability can size up, whilst taller pilots wanting quicker handling can size down. The 64.4-degree head angle and long wheelbase (1,231 millimetres in XShort, stretching to 1,311 in XLong) plant the front wheel firmly ahead of you, delivering calm at speed and confidence when the trail gets loose or steep. That slack front end pairs with a steep 78.4-degree seat tube to keep your weight centred over the pedals on climbs, so you're not fighting the bike when the gradient kicks up.

Chainstays hold steady at 446 millimetres across all sizes, which keeps the rear end snappy enough for manuals and tight turns without sacrificing traction on technical climbs. Stack sits at 633 millimetres regardless of reach, so taller riders get a more stretched-out, aggressive posture, whilst shorter frames feel more upright. The flip chip lets you swap between the stock mixed-wheel setup - 29-inch front, 27.5-inch rear - and a full 29-inch configuration without wrecking the geometry, so you can tailor the bike to your terrain or riding style. Mixed wheels sharpen the handling and make the rear end more playful; full 29 smooths out the rough and holds momentum better.

On trail, this geometry translates to a bike that feels stable and composed rather than darty or nervous. You'll carve through fast, open sections with confidence, and the long front centre keeps the front wheel tracking true over roots and rocks. In tight, technical sections - especially at walking pace - the longer wheelbase and slacker head angle demand a bit more input to change direction, and the weight becomes more noticeable. But once you're moving, the 675 feels poised and predictable, rewarding commitment rather than punishing hesitation.

Component choices & upgrades

The stock build is impressively well sorted for the money. Marzocchi's Z1 fork and Bomber Air shock might not carry the cachet of Fox or RockShox, but they're proven performers in the e-MTB world - damping is controlled, support is ample, and they shrug off the extra forces that come with motor assistance and heavier frames. Shimano Deore Linkglide gearing is purpose-built for e-bikes, with wider, more durable teeth that resist wear under high torque, and the ten-speed range (11 - 43 tooth cassette) covers most terrain without fuss. Four-piston Deore brakes with 220-millimetre front and 203-millimetre rear rotors deliver confident stopping power, even when you're carrying speed or extra battery weight.

Maxxis Assegai up front brings tenacious grip in loose or wet conditions, whilst the Minion DHR II rear balances traction and rolling speed. Both are tubeless-ready on 28-millimetre-internal Merida Expert rims, so you can drop pressures for compliance and grip without worrying about pinch flats. The travel-adjustable dropper - 125 millimetres in XShort, scaling up to 230 in XLong - gives plenty of room to move, and the integrated multi-tool under the saddle is a neat touch that saves you carrying spares.

If you're pushing harder or riding more demanding terrain, a few upgrades make sense. Swapping the Marzocchi fork for a Fox 38 or RockShox Zeb adds more adjustability and a touch more small-bump sensitivity, though the stock Z1 is more than capable for most riders. If you're regularly riding in the wet or tackling long, steep descents, consider upgrading to a four-piston brake with larger rotors - say, 220 millimetres front and rear - for extra power and heat management. Tyres are always personal, but if you're riding drier, harder-pack trails, a faster-rolling rear like a Maxxis Rekon or Schwalbe Hans Dampf will save watts without sacrificing too much grip. And if you're serious about all-day rides, the 360-watt-hour range extender is a no-brainer - it slots into the downtube and nearly doubles your battery capacity, turning the 675 into a true expedition machine.

Where the Merida eONE-SIXTY 675 excels

This bike is outstanding at long, technical trail rides where you want enduro capability without the weight penalty of a full carbon race machine. It thrives on steep, rough descents - the slack head angle, long wheelbase, and controlled suspension let you carry speed through rock gardens and root sections with confidence, and the Shimano motor's smooth power delivery keeps you moving when the trail flattens or kicks back up. The 750-watt-hour battery, combined with the EP801's efficient assist modes, means you can tackle big days without constantly watching the range indicator, and the optional extender pushes that capability even further.

It's also excellent for riders who want a single bike that handles everything from technical climbs to rowdy descents. The steep seat angle and assist carryover firmware - Shimano's clever trick that maintains power through momentary wheel lifts or loss of traction - make it a surprisingly capable climber for a bike with this much travel and weight. The durable Linkglide drivetrain and e-bike-specific components mean it'll shrug off the extra forces and mileage that come with motor assistance, so you're not constantly replacing chains and cassettes.

Where it's less ideal: tight, twisty singletrack at low speeds, where the weight and longer wheelbase make quick direction changes feel more laboured. If you're chasing the most playful, flickable ride or you prioritise nimbleness over stability, the eONE-SIXTY SL series or a shorter-travel e-trail bike will suit you better. And if you're primarily riding smoother, less technical trails or you don't need the extra battery capacity, you're carrying weight and capability you won't fully use. This is a bike for riders who want to go big, go long, and go hard - not for those chasing the lightest possible package or the snappiest trail manners.

Merida eONE-SIXTY 675 FAQs

What is the weight of the Merida eONE-SIXTY 675?
A mid-sized frame weighs approximately 25.6 kilograms without the range extender. That's hefty by any measure, but the bike disguises its mass well once you're moving, and the motor assistance offsets much of the penalty on climbs. Add the 360-watt-hour extender and you're looking at closer to 27 kilograms, but the trade-off is significantly extended range for all-day rides.

What is the range of the Merida eONE-SIXTY 675 with the 750Wh battery?
Range depends heavily on terrain, rider weight, assist mode, and how much climbing you're doing, but expect anywhere from 1,200 to 2,000 metres of elevation gain on a full charge in typical trail conditions. The optional 360-watt-hour extender can nearly double that, making multi-hour epics or back-to-back ride days entirely feasible without needing to recharge.

Is the Merida eONE-SIXTY 675 suitable for beginners?
It's capable enough to flatter less experienced riders - the motor smooths out climbs, the suspension soaks up mistakes, and the stable geometry inspires confidence - but the weight and enduro-focused handling might feel overwhelming if you're just starting out. A shorter-travel e-trail bike or the eONE-FORTY series would be more forgiving and easier to manage whilst you're building skills.

What are the key differences between the Merida eONE-SIXTY 675 and the carbon models?
The carbon eONE-SIXTY models save significant weight - typically two to three kilograms - and often come with higher-spec suspension and components, but they cost considerably more. The 675's LITE aluminium frame is tougher and more forgiving of impacts, and Merida backs it with a lifetime warranty, so if you're prioritising durability and value over outright weight savings, the alloy option makes a lot of sense.

Can I fit a different size rear wheel on the Merida eONE-SIXTY 675?
Yes - the bike ships with a mixed-wheel setup (29-inch front, 27.5-inch rear) but includes a flip chip that lets you run full 29-inch wheels without compromising the geometry. Mixed wheels make the rear end more playful and sharpen handling; full 29 smooths out rough terrain and holds momentum better. Tyre clearance maxes out at 29 by 2.6 inches, so you've got room to experiment with wider rubber if you want more grip or cushion.

What is the warranty on the Merida eONE-SIXTY 675 frame?
Merida offers a lifetime warranty on the aluminium frame, which is a strong vote of confidence in the durability of the LITE construction and P-Flex design. That covers manufacturing defects and structural failures, though normal wear, crashes, and improper maintenance aren't included - so treat it well and it'll last.

How does the Marzocchi suspension compare to Fox on the Merida eONE-SIXTY 675?
Marzocchi - owned by Fox - shares much of the same damper technology but strips away some of the external adjustments and premium finishes to hit a lower price point. The Z1 fork and Bomber Air shock are proven, reliable performers with controlled damping and ample support, and they're more than capable for most riders. Fox 38 or RockShox Zeb forks offer more tunability and a touch more small-bump sensitivity, but the Marzocchi kit is impressively sorted for the money and well-suited to the 675's enduro intentions.

Is the Merida eONE-SIXTY 675 good for climbing technical terrain?
Yes - the steep 78.4-degree seat angle keeps your weight centred over the pedals, and the Shimano EP801's assist carryover firmware maintains power through momentary traction loss or wheel lifts, which is a huge help on rocky, rooty climbs. The weight is noticeable at very low speeds, but once you've got momentum the bike climbs with confidence and traction, and the motor's smooth delivery makes it easy to modulate power through technical sections.
