This is how we test e-mountain bikes

The best e-mountain bike test in the world – transparent, non-biased and objective.

EMTB tests need to become more objective, comprehensive and detailed. That’s why we founded The only platform that looks at ALL bikes available on the market with an innovative testing system.
Full scale mountain bike tests – the most extensive in the world. All models, all categories, all price ranges.
The e-mountain bike market is so vast and diverse that its extremely difficult to find the perfect bike for your personal needs. No matter whether you are a emtb beginner, a changeover or a veteran e-bike nerd. That’s exactly why ex-mountain bike pro Ludwig Döhl founded After his active career as a mountain biker, Ludwig Döhl worked for BIKE, Europe’s largest mountain bike magazine, for over six years. But Ludwig quit his last position as deputy editor-in-chief of BIKE to implement his own vision of Bike Test. And that vision includes a sophisticated, innovative and totally objective testing system that not only transparently sorts out the complexities of the market, but also gives you an assessment of every bike without being biased towards any brand. The intuitive filters on our e-mountain bike market overview site help everyone find the best bike, depending on their own personal preferences. The only question that remains is: How can the entire emtb market be evaluated in a uniform and, above all, meaningful way?
During his time as deputy editor-in-chief of BIKE, Ludwig Döhl developed a new vision of mountain bike testing.
Ludwig Döhl was deputy editor-in-chief of BIKE, Europe’s biggest BIKE magazine. He noticed that the few test reports that appear throughout the year in various magazines no longer meet the market’s need for information. Therefore, with he has developed an innovative test system. It allows him to provide a mountain bike buyer´s guide for the whole market. Thanks to the test system of, the actual comparison of all mountain bikes is possible. At any time, anywhere and free of charge.

Which e-mountain bike components are used for evaluation

Overall, we look at each bike uniformly in over 100 meaningful criteria, which should give you a very good and detailed idea about the bike. Our evaluation takes into account all components that are relevant to the riding experience. The main components considered in our mountain bike rating system are:
  • Motor
  • Battery
  • Gearshift
  • Brake
  • Tires
  • Wheel
  • Chassis
  • seat post
  • Frame
  • Cockpit
The more than 100 criteria – which we evaluate in a standardized manner – are weighed up independently, depending on the intended use. And that´s the key to our statement quality. Our goal is not only to compare two rear derailleurs that are installed on different bikes, but a lot more: we want to give you an impression of the riding experience that you can expect from your future e-bike. And to do so, we have not only broken down and weighed up evaluation criteria in detail, but have also taken a look at the geometry of all bikes. But first things first.
These are the components we evaluate on a mountain bike.
A e-mountain bike is a miracle of technology. There is hardly any other machine in the world that allows you to move around as efficiently as a mountain bike. To do it justice, we evaluate every component that is installed on a emtb.
Brakes, chassis, gears, wheels, geometry. You have to pay particular attention to these components on a mountain bike.
In order to represent the complex product of mountain biking as simply as possible, we have divided the equipment into different assemblies and reflect the absolute value in this spider web diagram. The larger the blue area under the respective point (brakes, chassis, gears, wheels, geometry), the higher the quality of this assembly. We not only evaluate these criteria, but also compare them directly with the relevant market environment (purple chart).

We apply these evaluation criterias to our emtb tests

For the evaluation of the individual components, we use, among other things, the followng criteria. They get considered differently, depending on the component and to which area of the e-bike this part is installed
  • Weight of the component
  • ranking in the manufacturer-specific product hierarchy
  • product-related physical facts (e.g. larger brake discs have better braking performance. A larger bandwidth of a gear shift is better than a smaller one…)
  • general design-related facts (e.g. folding tires are of higher quality than clincher tires.)
  • function of a component (experience from practice and everyday life in bicycle workshops)
  • product specific criteria (e.g. tread depth of tires)
  • material used for a component
Every evaluation contributes to a complete bike check on Moreover, it can be traced back to one fact: EVERY E-BIKE, NO MATTER FROM WHICH MANUFACTURER, IS TREATED EXACTLY THE SAME. To make the whole thing as close to reality as possible, an example would be the rating of a brake for a enduro e-bike. It is, for example, more important at a Enduro bike than for a cross country e-bike. This equation lends itself to get the most balanced and non-biased bike reviews on the market!

The handling – the soul of any emtb

Mountainbike equipment in direct comparison.
To give you not only an absolute assessment of the equipment, we have also compared it with the relevant market environment. Our price/performance slider tells you at a glance how much bike you get for your money.
The character of a mountain bike can better be judged with a lot of experience. This is extremely important if you want to be happy with your bike in the long term.
Here we demonstrate the character of a bike with its various uses. The traits of a bike are not evaluated as “bad” or “good”. Rather, if the bike character will suit you more or less.
Reach, stack, steering angle …? Excuse me? Anyone who deals intensively with EMTBs before buying is quickly overwhelmed by the technical jargon of the industry. Therefore, we have not only evaluated the equipment of each bike, but also took a detailed look at its geometry. So you don’t have to take a degree in bike science yourself, we’ve analyzed the geometry of all bikes uniformly. The handling of an EMTB is not only due to the pure geometry data. Especially the weight plays a central role in EMTB handling. In our understanding, an e-mountain bike has good handling when you actually do not notice that you are sitting on an EMTB. The closer the riding feel of an e-mountain bike gets to the handling of a mountain bike without a motor, the higher its fun potential on the trail. A harmonious onset of motor support is also particularly important. In our handling score, we therefore mix:
  • an evaluation of the geometry
  • a classification of the weight
  • the engine characteristics
to a tangible value for each bike.
EMTB Handling
How the handling of an EMTB feels in the terrain depends not only on the geometry. Our experience has shown that the closer the handling of an e-mountain bike is to that of a natural mountain bike, the more fun it is. And that’s exactly what our Handling Score reflects.

Range – this is how far you can go with your e-mountain bike

The range depends on many factors. You can influence some of these factors directly while riding. For example, if you always ride in the highest support level of the motor, a battery charge lasts less long than when pedaling in Eco mode (the lowest support level). Heavy riders use more battery than light riders on the same trip. And on a ride on tar and gravel roads, the battery lasts longer than on a trail ride through muddy ground. Oh yes, and when it’s warm, a battery also lasts longer than in frosty temperatures. Therefore, it is simply not possible to give a meaningful meaningful mileage value at the range. Because this mileage varies significantly depending on who, where and especially how rides the EMTB. But there are also factors that influence the range of an EMTB independently of the question of “who, where and how”. The tire profile, the weight of the EMTB, the efficiency of the motor and, of course, the capacity of the battery are all crucial in determining how far you can ride an EMTB. With our range score, we have brought these values on a comparable basis. So you can see with which EMTB you tend to get further. Whether that corresponds in your case then a range of 60 or 70 or maybe only 45 kilometers we can unfortunately not tell you. But we can tell you that you will get further with a high range score than with a low range score.
EMTB Reichweite
Statements about the range of a bike in kilometers are only possible if you know who, how and where you ride with the EMTB. In the range calculation at the EMTB control center, these values are taken into account. To create a uniform information, we have calculated our range score for all bikes on
