Recuperation, charging cycles, EPAC? In KTM e-Bikes you can find high-end technique. We want you to be informed and therefore you can find the most important terms described below:



eBike or Pedelec (PEDal ELEctric Cycle) - are usual terms for electric bicycles which, in the most cases,  are not 100% correct. EPAC (Electric Power Assisted Cycle) is the only, legally correct term. Ein EPAC is defined this way: not requiring a licence / the engine supports only when the rider pedals / assistance only up to 25 kph / 250 W nominal engine power.

LED Display

Displaying of a certain state by an array of light-emitting diodes on the console. For example the remaing battery power is displayed by 5 lamps - if 5 lamps are lighting this means the battery is fully loaded - if 3 lamps are lighting this means that the battery is 3/5 loaded. 

LCD Display

Displaying of certain states directy in numerical values or bars on the console-display. For example the remaing battery power is displayed as bars. Additionaly the speed, assistance level and further functions are displayed by a numerical value.


Recuperation means that the battery is charged by the engine. Thus the reach can be prolonged by 15%. Recuperation is only possible at rear hub engine EPACs because of their mechanical assembling. E.g. recuperation is activated while pulling the brake lever. Additionally recuperation can be activated while riding downhill. The engine is working like a generator and thus is an additional brake.


A frequently discussed topic in the world of e-bikes. Generally spoken: the reach depends heavily on many various conditions (assistance level, weight of the rider, terrain, wind, tire air pressure and outside temperature) and can only be given as a guideline by the manufacturer.

The KTM given reaches are guidelinis of the respective driving system manufacturer and relate to optimal conditions.

These are: Flat terrain without headwind, 20°C outside temperature, specially narrow tires without profile, rider weigth below 70kg and a few more.
By optimal use of the recuperation (rear hub engine) the reach can be prolonged by 15%.

Generally there's no compulsory wearing of a helmet (State: September 2013). Nevertheless we recommend to wear a certified helmet as well as adequate clothing while riding an EPAC.

Max. load
The max. load (rider+luggage) is 118kg (only a few exceptions). KTM carriers may be loaded with 25kg. Exceptions are marked.

Volt [V]

Is the unit for electric potential.

Ampere [A]

Is the unit for electric current.

Ampere-hour [Ah]

Ampere-hour is the unit for electric charge - indicates which amperage can be taken within an hour from, in this case, the battery.
Watt-hour [Wh]

Is a unit of energy - it indicates which performance can be taken within an hour, in this case, from the battery. Watt-hours are more transparent that amp-houts because the performance is a product from voltage and amperage. This way it's easier to calculate the reach.
Newton metre [Nm]

Is a unit of torque - One newton metre is equal to the torque resulting from a force of one newton applied perpendicularly to a moment arm which is one metre long. It accelerates, in case of an EPAC, the rotation of the wheel.

Brushless DC electric motor

There's no connection over the brushes, which can wear out, from rotor to stator at the brushless DC electric motor - in contrast to the conventional DC electric motor.This means the Brushless DC electric motor is maintenance-free, The motor consists of a permanent magnet, the stator of several magnetic coils.

Nominal power

The nominal power is the average power indicated by the manufacturer at which the engine can be used permanently (EPACs 250W).

Maximal power

The maximal power is the power indicated by the manufacturer which the engine can apply for a short period of time, e.g. to accelerate the bike.

Charging cycle

A charging cycle is one complteted chargíng of the battery.

Indicated charging cycles = Guaranteed charging cycles

KTM guarantees these charging cycles for a period of two years and a battery capacity of at least 70% of the mint condition.
