Frequently Asked Questions

Rubbee X is probably the easiest electric bicycle conversion kits to install. Attach the lock mechanism onto the seat tube of Your bicycle and insert Rubbee X into it. There’s also a small wireless cadence sensor that must be attached to Your pedal crank before the first ride. But don’t worry – no wires or magnets go to or from it, just two cable ties to secure it and You’re good to go ! Rubbee X is considered to be the best e bike conversion kit regarding ease of installation.

Installation Guide:

Short answer – You control it by pedaling.

Rubbee X is controlled by an easy to install PAS (Pedal Assist Sensor) or in simpler terms – wireless cadence sensor. The sensor is mounted on the bicycle pedal crank and it provides information about when and how fast the person is pedaling. By knowing these things and combining them with the speed of the entire bike, Rubbee can control the amount of power independently without any user interference. When You are pedaling – Rubbee provides power. You stop pedaling – Rubbee stops providing power and starts freewheeling . Rubbee becomes a natural extension of Your muscle power. When a hill is encountered and Your speed is decreasing but pedaling rate increases Rubbee enables a higher power output. High speed and slow pedaling will have an opposite effect – a lower assistance level will be provided. Rubbee X makes these calculations and power modulations multiple times a second.

The maximum assistance power level of the ebike conversion kit can be controlled via the main button. Just press is to cycle through different power modes. ECO / CRUISE / POWER modes are available depending on how many batteries are installed. ECO is available with 1 installed module, CRUISE with 2 modules and POWER mode becomes available when all 3 battery modules are installed. These modes can also be changed via the smartphone application.

Yes it does !

When pedals are turned backwards for half of a revolution, regenerative braking mode is enabled. Since Rubbee X is an ebike kit with battery, when a long downhill section is encountered the regenerative braking can recharge the batteries. Normal operation is automatically resumed once pedals are turned to move forward. When the batteries are fully charged, the regenerative braking mode will not be available until the batteries are discharged to the allowed limit.

In most cases, it does not slip. There are 3 key reasons why.

Electronic anti-slip control. If slipping is detected, the motor torque modulates similar to how ABS system works in a car.

Active suppression system. Rubbee X is pushed to the tire not only by it’s weight, but also with a 200N pneumatic cylinder.

Special roller. Both material, shape and surface texture of the roller is optimized for increasing grip in all weather conditions.

Rubbee X adds additional wear to the tire but nothing that should be worried about. We cast the rollers from a specially developed polyurethane compound mix which guarantees the best contact between the tire and the roller. This compound also allows us to reach phenomenal grip in wet conditions. We test roller materials for thousands of kilometers (literally!) on the same tire without drastic wear&tear. In any case it is generally recommended to change bicycle tires every 2000-3000 km so we recommend to follow this rule. Cool fact – our roller material is also used in high-end sports cars suspensions !

Yes! You can change from one bike to another in just a matter of seconds. The only thing You will have to do is to install the Second Bike Kit on the other bike. It includes a sensor and the lock mechanism. One Rubbee X – two (or more) DIY ebikes !
