Benefits of the Gboost E-bike Retrofit Kit
(compared to others Retrofit Kit Friction Drives eg. add-e go-e)

Small & light-weight

The motor unit is so small that people will barely notice the motor mounted to the bicycle. It weighs only ~950 grams.

Cycling with no battery & Energy-recovering

The motor can be fully disengaged to guarantee no braking forces what so ever in the normal bicycle mode. So you can continue to use your Gboost-ebike without motor assistance also as a normal bicycle. Or you can keep it engaged to re-charge your battery when rolling downhill and also use less your breaks.

Easy to install in minutes

The Gboost-E-bike-Kit can be installed in no time on any size of bicycles, without the need of special tools or skills…

  • one screw only to fix the motor & control unit.
  • no need to install an external magnet disk (on newer bikes is often not enough space) 
  • no a battery-powered wireless senors (another battery and wireless connection failure risk)

(and compare to others like add-e or go-e)

Proven high reliability

To survive the daily use, especially in wet and dirt conditions, the Gboost motor is a real closed design. Dirt and water will cause no damage or corrosion. All connectors a sealed, too. 
The bearings, one on each side, are over-seized to take the tire pressure loads to ensure for a long live.

(Other friction drives on the market use just standard stock RC model motor designs, which are very sensitive to dirt because and corrosion, due to their open air-cooling design.  These RC motors also have and only one small bearing on one side, not designed for the tire pressure load and fill fail sooner or later. )

Thanks to our special designed control technology, there are no external sensors or hall sensors needed. 

Our Gboost V2 was sold over 1000 units in Decathlon stores, with an exceptional low failure rate and still running strong, thus of their fully closed design. 

 

Ultra silent

The newest engine technology paired with our internal damping makes the Gboost is so quiet that bystanders cannot hear whether you are driving with or without engine assistance.

GBoost is still the only really silent friction drive in the market, you can buy today.

Internal Pedal Sensor:
simple, reliable & compatible with any pedal crank

Thanks to the the integrated pedal assist sensor (patent pending), just stick a tiny magnet to the pedal crank, save time and forget it for ever.

There is no more need to install a classic pedal assist sensor and the ugly magnet disk as well. This also often caused installation challenges in the past, thus in many modern pedals systems is not enough space for the magnet disk.  The old classic external sensors often fail, either because so sensitive to the position (+-2mm). And the newer wireless external sensors, often run out of their battery or even have disturbed wireless connections in some areas.  We used this solutions in the past…   not anymore… 😉

Extreme efficiency and Range
works with not perfect round wheels


To avoid the slipping of the motor, a patented pressure regulation assures that there is just enough pressure of the motor onto the tire, so it is not slipping (also in wet conditions). The motor should also not press too much and deform the tire, thus this would waste energy. 
This regulation mechanism also compensates for less tire air pressure or not perfectly round turning wheels. (Which is not so rare in real day to day usage of bicycles)

One more thing, for the geeks… : The pressure regulation is also responsible that we have unbeaten efficiency among friction drive systems, even outperforming many classic e-bike systems.
And better efficiency means, you will get more range with the same battery
