The Motor

You can choose the more suitable motor for you depending on the level of assistance of your choosing as well as the engine performance. If you wish a medium level assistance, the Motor 24V (25km/h) will be the perfect fit, on the other hand if you want more performances, go for the 36V or 42V (36km/h) motor.

For European countries we strongly recommend the gold version – meeting the legal requirements of EN15194 – and the Platin version (300W) for non European countries.

The motor does not require any specific care, nevertheless it still needs some upkeep in order to work properly, such as:

  • Replace the adhesive tape (3 replacement bands will be available into the package) once it is worn out or damaged. To replace it you will need a hair dryer in order to warm the adhesive tape before removing it from the motor.
  • If you wish to clean your motor from the durt or dust we strongly advise you against using a high-pressure cleaner. Instead use a damp sponge.

The motor is adjustable to all bikes (road bikes, city bikes…) Nevertheless, we do not recommend its use on mountain bikes du to the spiked tires. Indeed, working with spiked tires will make the motor more noisy, it will increase its wear as well as the wheel’s wear and decrease its efficiency.
If in doubt, please feel free to send us a picture of your rear wheel, so we can work on a tailor-made motor for you !

Absolutely yes ! Our product is suitable for all wheel sizes. It will work just as much on a junior wheel (a child bike) than any other wheel.
The Motor Kit consists of many items :

  • The motor
  • The remote control
  • The wiring
  • The power switch (on/off)
  • Mounting plates
  • Basic tools(screws)
If the motor is well maintained and is not damaged, it does not need to be changed. Indeed the product is designed to be long-lasting and reliable. It does not wear.

Best suited for the Gboost-System are tires with a flat even running surface in the center. Typical mountain bike tires are not recommended since they generate vibrations and noise. We recommend switching to tire types as shown on the left side of the picture below.


By the way, you should be aware that mountain bike tires have a higher roll resistance than street or city tires. So you will need to put more energy into your bike to reach the same distance with a mountain bike tire than with a city tire, or in other words, your pedelec runs less far on the same batterie.

The wear and tear of your tires depend first and foremost on the quality of your tires. However the fact that the motor is in direct contact with the rear wheel may accelerate its wear (from 30% to 50% more). The renewal will depend on the quality/performance of your rear wheel as well as its wear, the frequency and intensity of use.
We offer 2 levels of maximum speed depending on the type of motor you ordered:

  • 25km/h (+/- 10%) for the Gold
  • 36km/h for the Platinum
Yes, it is possible to retain energy while braking, however, it remains quite minimal and therefore does not really affect the endurance.
Yes, the motor and battery being waterproof, It allows you to ride your bicycle everywhere no matter the weather.

The Battery

Tough question ! The battery life depends on many external factors (the outdoor temperature, the wear (flat roads,uphills..), the degree of desired assistance.. ). However, to give you an example, at its maximum capacity (250W, going uphill), the battery will last for about an hour (app. 30km), as well on a flat road you can go up to 100km of battery life (assistance level 1).
If your battery is running very low, the charging time will be about 3h – 5h if you want it to be fully charged.
  • Gold   – 3h 10mn
  • Platin – 4h 48mn

We are currently selling just one type of battery. For more information regarding the product, click the link –> x.

The Battery Kit consists of 5 items :

  • The battery
  • Its mounting bracket
  • Holding clips
  • A key to lock the battery so it is theft-proof
  • A charger
It weighs approximately 2kg.

The battery does not require any specific care, nevertheless it still needs some upkeep in order to work properly, such as:

  • Do not expose to temperatures exceeding 50°C
  • Store in a dry place at room temperature and keep away from direct sunlight.
  • Do not use a high-pressure cleaner.
  • Long term storage can accelerate battery self-discharge, and lead to the deactivation of reactants, therefore, fully recharge the battery every 3months
