The manual and tips for KOSTKA e-footbikes

This is a smart e-footbike produced in Czech Republic. You can travel so easily and so lightly as you have never experienced before. The system is based on sensors which are located in footbike’s hub. These sensors record people’s motion activity and respond to all your impulses. Whether you want to ride faster or slower, the footbike adapts to all what you need - you will experience the feeling of synergy and enjoy the swiftness and ease of motion.

Three modes, many possibilities

There is a lot of options you can set up. And then you just kick off! You can set up parameters using a mobile app which adapt footbike’s behaviour to your needs.

PEDELEC modeThe PEDELEC mode will enhance the needed pushing power, so you can move very easily. If your speed drops to 6 km/h, the footbike will maintain it. Since it is speed of an agile person, you can easily move among other people. The speed support works up to 25 km/h.

FUN modeThe FUN mode adds another function - it will maintain the last reached speed for the specific duration you set up. It includes the push-enhancement function, just as in the PEDELEC mode. Both modes include energy recovery. The maximal speed of the FUN mode is 20 km/h.

OFF modeIf you want to get a little soaked and ride the footbike the way it has to be - without help. Simply set the mode to OFF - standard footbike mode.

No cables

You no longer need to worry about cables or unwanted damage. This unique system is based on the All-in-one solution, which means that all equipment (including sensors and batteries) is placed in the compact e-hub with nominal power 250 W.


No registration or insurance needed

Without license The Footbike Pedelec mode meets the strictest German legislation for electric footbikes - and you need not register anywhere or have an insurance.

*The legislation requirement can differ from country to country. You should always check the information of the appropriate country authority. E.g. in Czech Republic you can use all modes without any restrictions.

Safe and controllable

The big front wheel provides you an easy ride through all obstacles. The tires Schwalbe (German brand) will provide you a comfortable feeling. The optimized geometry is based on the long-year experience in footbike production. This makes our footbike models very stable and easy to control. You needn’t be afraid of an unpleasant bumpy ride because the e-footbike is small and unstable. The brakes Shimano will provide an excellent braking performance. Now you can simply enjoy your ride!


Control by phone app

You can connect to your mobile device via Bluetooth and check your speed, your location or distance travelled. The whole setting is done through the mobile app - there you can choose various parameters such as:

  • - Boost (the kick-assist intensity),
  • - Assistance (the value of the distance over which the speed achieved during kick-off will be maintained - up to 1km),
  • - Braking (the braking intensity using the BT controller; only active with the BT controller - not included!),
  • - High speed braking (the intensity of the regenerative braking - active from 30km/h).

You can pair more footbikes with your account and choose the one you use. However, a smartphone is not required to drive! It serves mainly to set up the mode.

Mobile app

Energy recovery (recuperation) and quick charging

Recuperation You can use the energy recovery while braking or downhill riding, which allows you to charge a little bit energy back again. The time it takes to charge can be only about 2 hours using a standard 2A charger, which won’t overuse the battery too much, so that it can hold up to 1000 charge cycles! In PEDELEC mode, recuperation is activated at 30 km/h and in FUN mode at 25 km/h. The intensity of recuperation is adjustable.

Long range

Distance 160 Wh lithium battery provides a highly-developed power management and energy recovery system. The PEDELEC mode ensures the range of 50 km, while the FUN mode up to 20 km. But the real values always depend on the assistance set up, route profile and footbiker’s weight.

Stretch your body

Movement We preserved all qualities of a sports footbike. That’s why the ride is quick and easy but and you can stretch your body without any additional efforts. Do you want to exercise while coming back home from work? You can just reduce the engine power and make something good for your health! The footbike helps you to stretch and strengthen your muscles, improve your joint condition and prevent back pain.

Low weight but big weight capacity

Weight The weight capacity is designed for 120 kg while dynamic load. We test the lifespan of our footbikes on our testing places, where we check the material fatigue behaviour during real ride simulation. A low weight of this e-footbike ensures perfect driveability and manipulation.


You can fold the footbike easily in two steps within a second. The FOLD system provides the handlebars folding and the SPIN system ensures that the frame can be rotated around its axis. You will get a compact package which you can carry while travelling by public transport or car and which you can deposit where it is necessary. Our unique folding systems will help you with this!


No one will get away with her

Motor lock Our e-KOSTKA has the option of locking the engine as a protection against unauthorized use. When the e-KOSTKA motor is not rotating, the speed indicator changes to a lock icon and the motor can be locked. When the lock is activated, the motor has a high resistance to rotation, so normal driving is not possible. If you try to control the application or go to the e-KOSTKA when it is locked, a message in the application will alert you.

*The engine lock function does not replace the classic bicycle lock and does not secure the footbike against theft!


16"-12" Folding street e-footbike

KOSTKA e-REBEL MAX FOLD is a light e-footbike which can be folded up easily within 20 seconds! You will appreciate improved qualities of this adult footbike especially in the city traffic, but it’s good for short trips as well.

The main advantage of this footbike is an extraordinary dexterity, extremely light weight and small size. You could even put it in your pocket, if we exaggerate a little bit. But it’s no exaggeration to say that you will leave behind all other drivers on the road.

So you can easily take it to the stairs or ride over every obstacle that gets in your way. When folded, its measures are only 82×64×20 cm, which makes it easy to carry in public transport or to be stored in a small apartment.

The footbike’s resistance is guaranteed by the frame which has been formed from very solid (CrMo) steel and reinforced with special welding and a stiffener on the lower side. The frame is not only protected against deterioration by them, but they make it tougher as well. The extraordinary dexterity and comfort are provided by the inflatable wheels are covered with high-quality tires Schwalbe Big Apple. If you encounter unexpected pedestrians, cars, trams, or a crazy dog... or perhaps a hole in the pavement road, you can always stop using the brakes Shimano.

The model KOSTKA e-REBEL MAX FOLD is equipped with a transport bag and a strap which protects the footbike against damage and makes it easier to carry it at the same time. A short strap allowing you easy rear-wheel transport (when folded) is also included.

Jeden Tag was dazu lernen

Gestern habe ich viel über technische Herausforderungen geschrieben. Falls noch Platz ist, möchte ich heute noch ergänzen, dass der KOSTKA REBEL selbst toll ist! Leicht, klein, hochwertig, klappbar, stabil, Ergonomie sehr angenehm. Passt in jeden Bus, Zug und Kofferraum vom Auto. 5 Sterne!
Auch die Idee, einen Tretroller mit e-Motor auszustatten, der wirklich die Tritte verstärkt und KEIN e-Scooter ist bekommt von mir 5 Sterne! Ich kenne keine vergleichbare Umsetzung, das ist wirklich etwas besonderes. Vorteile:
- keine Zulassung, im Schritttempo darf man auch auf Fußwegen fahren, wo Fahrrad und e-Scooter nicht erlaubt sind
- 6km/h im Pedelec-Modus zu halten ist eine super Idee
- Der Fun-Modus erleichtert bergauf fahren sehr (wenn man rechtzeitig Schwung holt)
- Viele Möglichkeiten, den Modus anzupassen (das ist auch der Nachteil, es dauert, bis man alle Funktionen verstanden hat und im richtigen Moment einsetzt)

Zum Problem mit dem zu starken Schub beim bergab fahren (Bericht oben von gestern) könnte das eine Lösung sein: Fun-Modus bergauf auf 100% Unterstützung, wenn man oben ist Pause machen und mit der Zehus App die Unterstützung maximal reduzieren (das geht nicht mit der Fernbedienung). Zum üben und lernen bergab den Pedelec-Modus mit reduzierter Unterstützung einstellen. So müsste es auch mit der Rekuperation klappen.
Ich wünsche, dass der E-Kostka viele Freunde findet und den Fahrern wünsche ich Geduld beim lernen, wie die technischen Feinheiten funktionieren.
