add-e - the solution to electrify your bike

Electro bikes are gaining more and more popularity. The constantly developing technologies and materials are making e-bikes faster and more powerful.

But why buy a new bike?

add-e is the solution to convert your own beloved bike into an electro bicycle, which allows you to use your own conventional bicycle with the newest technology. This also gives you the possibility to save space in your garage, saves the environment and is lower priced than an electro bicycle with comparable quality.


add-e is not only unique in size and weight, but also extremely powerful. add-e can easily be attached onto a bicycle, and the modular construction enables you to convert almost every bicycle without affecting the frame or other parts of the bike. add-e is inconspicuous in design, but also enables the users to ride their bike without interfering the cycling experience itself. This unique feature is possible because add-e is completely decoupled when on standby mode.

add-e electrify your bike


add-e is an add-on kit, that allows you to convert your conventional bike into an electro bike. Absolutely no permanent modification has to be made to the bikes’ frame or other parts.

The mounting kit is fixed onto the bikes’ frame within standardized attachment points for the initial fitting. Additional mounting kits enable the use of add-e on a number of bikes. This unique concept allows you to convert as many bikes as wished with one and the same drive unit and battery with simply attaching and removing them within seconds.

The special swing-arm mechanic allows normal cycling without friction and resistance during standby mode. If a support is needed a simple twist of the power-regulator, which is located in the cap of the battery-bottle, switches add-e on. The drive unit connects with the rear wheel and helps you easily overcome any obstacle, such as raising slopes. add-e can easily go back to standby mode by twisting the power-regulator back.

add-e is light weighted, nearly invisible and extremely powerful

add-e Drive unit

The add-e Sport Edition reaches up to 600 Watt and allows top speeds up to 45 km per hour (28Mph). The power regulator, which is hidden in the cap of the battery bottle is not only responsible for switching from standby- mode to power, but also allows selecting one of 5 different power-levels, starting with 50 Watt, for keeping up with your group and increasing up to 600 Watt, to support you to overcome obstacles such as slopes.

The actual range that can be achieved, does not only depend on the selected power-level, the bike on which add-e is attached on, or the individual human performance, but also on the external influences, such as wind, slopes and the surface add-e is used on.

With constant use, distances of up to 50 Km (31miles) can be achieved with only one battery. If only used when support is needed, to overcome hills and other exhausting obstacles, a daylong tour can easily be mastered with one battery load. The drive unit does not create any friction or resistance when on standby mode, and with a weight of only 1 Kg (2.2 pounds) there is no noticeable effect on the cycling experience. The compact design and shape, which measures only 7x8x8 cm (2.76×3.15×3.15 inches), makes add-e almost invisible and for sure can surprise others.

  • inconspicuous design
  • weighs only 2.2 Kg
  • compatible with nearly all bicycles
  • 100% decoupled in standby-mode
  • low cost mounting kits allow initial fitting for further bikes
  • attaching/removing add-e within seconds
  • Cycling with no battery,. no problem

add-e Mounting kit

add-e can be mounted on with 2 different possibilities, depending on the frame of the bike. Both solutions are included in every add-e set, and no permanent modification has to be made on a bike.

Typ1 Bottom bracket mounting

The bottom bracket mounting is the perfect solution for racing-, mountain- and most trekking bikes. The standardized bottom bracket allows an easy mounting, which is applied through the bottom bracket shells for fast and secure mounting.

Typ2 Kickstand holder mounting

The kickstand holder mounting is the ideal solution for city bikes and older bikes which posses a classical kickstand bracket. For this option, the mounting plate is fixed directly on the kickstand holder. The usage of a universal kickstand holder can be used to easily mount the plate on different variations of bikes.

Please feel free to contact us by sending a picture of your bike; for any information regarding the best mounting option and perfect fitting for your bicycle.


add-e Battery

add-e stands for understatement. For the first time ever the battery bottle actually is based on a bottle design. The strong aluminum housing protects the high performance cells from mechanical damage. The build- in Battery-Management-System (BMS) guarantees a long endurance of the battery and secure charging.

The built-in power regulator, which is situated in the cap of the battery bottle, is not only responsible for switching from standby to power mode but is also relevant for choosing between the 5 different power levels of the drive unit.

We offer 2 different capacity types of batteries, both are compatible with the lite and sport edition of the drive units. The innovative modular system changing of the battery is no problem and can be changed within seconds.

Each add-e set contains the standard battery with a capacity of 7.2 Ah (160Wh) . This battery type allows over two hours of constant support. We also offer a battery with a capacity of 9 Ah (200 Wh), which is identical in weight and design and provides up to four hours constant support.

Both Battery variations feature  a 5 level LED Status  indicator to show the remaining capacity of the battery.

  • approximately 50 km(31 miles) range
  • ON/OFF(standby) & performance adjustment
  • Weight 1 kg
  • high performancet lithium cells
