Merida eSilex 400 Electric Gravel Bike LIFETIME WARRANTY

Merida eSilex 400 Electric Gravel Bike the answer, the development of gravel bicycles and electric bicycles (e-bikes) in recent years is “up and coming”. So, what if we combine the two “concepts”? yup, Gravel E-bike.

While there are some specifics you need to consider when buying an e-bike specifically for “off-road” such as the gravel, most of the things you need to check are the same as with any other electric bike. Check out our handy guide on how to buy an e-bike here. You need to consider the type of bike, placement and torque, battery size and range, bike weight, and, of course, your budget.

Just like a conventional gravel bike, it can also make a great city or commuter bike, thanks to its sturdy wide tires and wide gears which come in handy when you are carrying a lot of stuff. In this case, you need to consider safe storage and charging, as these bikes tend to be quite expensive. 1

The rear hub MAHLE motor system X35+offers 40 Nm of smooth and drag-free support and is powered by a 250 Wh internal battery. The system is controlled by a one-button iWOC switch which is positioned on the top tube. Different colours of the switch indicate the support as well as the battery level.

MAHLE ex35+ Hub Engine

  • 40Nm


To keep the cockpit as clean as possible, we have placed the iWOC on/off switch on the top tube. This location makes it perfect for reaching it in every riding condition. MAHLE’s iWOC switch is not just an on/off switch but the rider can also toggle between the different support level by pressing the button. Different colours of the ring indicate at which level the system is running. Due to the combination of on/off and switching levels in one device the bike has a sleek and clean appearance, especially around the cockpit area. For an even cleaner look, the cables are routed through the headset directly into the frame. This means no e-motor cables at the front end of the bike.


Should the 250 Wh battery not be enough, or you are intending to go for an extra-long outing, then you can fit a 250 Wh range extender. The range extender can be attached to one of the bottle cages fixing points and plugs straight into the system for immediate range extension.


  • 250Wh

The battery is the heart of the MAHLE ebikemotion system. It is not only the fuel tank for the power supply; it is also the brain of the whole system. The control unit for the rear hub is also located in the thin battery casing. While the 250 Wh capacity doesn’t sound a lot in the first instance, the weight and the efficiency of the rear hub engine in combination with the riding style of an e-road bike, the battery has enough capacity to have a long day in the saddle. And should the integrated battery provd to be not sufficient for an extra-long outing, then a 250 Wh range extender, that can be mounted to the frame like a water bottle, will make sure that there is plenty of juice in the tank.
