The battery integrated in the down tube has a capacity of 236 Wh. An additional bottle-shaped battery can be on the seat post bottle holder to add 171 Wh to the system. As in the previous version, a software system and apps are available both for the user and the retailer to manage, monitor and configure the system.
To improve the riding experience, we have introduced a new bottom bracket with torque (power) and frequency sensor. The cyclist (through pedalling, i.e. the power the cyclist delivers) communicates with the motor via the frequency and power sensor. The system reads the “pedalling power” to modulate the assistance delivered to give the cyclist a natural pedalling experience with no jerks, sudden accelerations or loss of assistance. For example, the motor will continue to deliver power smoothly even on steep inclines of over 10%. All of this is necessary as we move toward a cycling experience similar to that of a traditional bicycle.
The power sensor (with the new firmware) also optimises battery consumption, since the power provided by the motor is much more sensitive and proportionate to the power delivered by the cyclist.
