Merida eSilex 400 Electric Gravel Bike in Low Key Green/Brown

Season:2026

Brand:Merida

Code:P-R893

Sometimes a small push is all that's needed to open up a whole new world of exploration.

The Merida eSilex 400 electric gravel bike pairs a sleek, lightweight frame with versatile gravel tyres on 700c rims with the helping hand of the latest MAHLE ebikemotion X30 hub drive motor and a 237 Wh battery, so you can ride further without the faff of planning around your legs.

A fully-featured frame and carbon fork with plenty of mounts makes it ideal for overnight bikepacking trips or smaller adventures, while the smooth shifting and powerful braking of the Shimano GRX groupset with double chainset makes for reliable company, on or off the road.

If you often find yourself eyeing up the bridleway when you're out riding, or you simply enjoy going wherever the mood takes you, the eSilex 400 is worth a serious look.

As Merida e-gravel bikes go, this one sits in a sweet spot: enough motor assistance to take the sting out of long days in the saddle, without ever feeling like a motorbike.

The rear-hub MAHLE X30 system with integrated battery delivers support that feels natural rather than intrusive, and if you're planning a longer stint, an externally mounted 208 Wh MAHLE Range Extender can boost your range further.

For those who want the full specs and more details before committing, it's worth knowing the eSilex comes in both 650b and 700c wheel sizes, so you can pick the setup that suits the terrain you're most likely to tackle.

Merida bikes have a strong reputation for building frames that punch above their price point, and the eSilex 400 is no different. The triple-butted aluminium frame keeps weight down, while the carbon fork and extensive mounting points mean you can load it up for a multi-day tour or keep it stripped back for a weekend blast. Either way, it's ready.

  • Latest MAHLE ebikemotion X30 hub motor for natural-feeling assistance
