Merida eBig Nine 400 Electric Mountain Bike in Silk Dove Blue/Blue

Season:2026

Brand:Merida

Code:P-R806

The Merida eBig Nine 400 gets the balance right in a way that a lot of electric mountain bikes simply don't. Sporty enough to be genuinely exciting on the trails, comfortable enough to keep you out there for hours.

If you've been looking at Merida electric mountain bikes in the UK and want something that actually performs off-road rather than just ticking a spec sheet, the eBig Nine 400 is worth your attention.

The details:

  • Power when you need it
    The 85Nm Shimano EP6 drive unit gives you a serious assist on climbs and technical sections, the kind of boost that makes a brutally steep singletrack feel manageable rather than miserable. It's a motor that responds naturally to your pedalling, so the ride never feels artificial.

  • Range that doesn't let you down
    The 630Wh battery keeps you going for a proper amount of miles, so you're not constantly clock-watching or cutting rides short. For longer days out on UK trails, that range matters more than most spec points.

  • Control on any terrain
    SR Suntour suspension soaks up the rougher stuff, chunky tyres give you grip when the ground gets loose, and Shimano brakes bring you to a stop with confidence. The Merida eBig Nine 400 handles varied terrain without asking you to fight it.

  • Built to last
    The high-quality aluminium frame keeps unnecessary weight out of the equation, and it comes backed by a lifetime warranty. For a Merida bike at this price point in the UK, that's a reassuring long-term commitment.
