2020 YAMKA E4

Motor

Silent and comfortable Apache Power Silent drive unit with the Silent plus electric motor will make each ride you take very pleasant / each urban ride very pleasant. The motor is positioned in the hub of the front wheel. It has a nominal output of 250W and maximum torque of up to 45 Nm. The system is equipped with the so-called “sinusoidal control technology” that is characteristic by very silent operation and more efficient use of energy. Thus, your e-bike has greater range per one charge, which extends your options.

Battery

This modern battery placed on the rear side of the seat tube has the capacity of 13Ah (468Wh) and the range of up to 110 km per a single charge. The total range is influenced not only by the battery capacity, but also by the profile of route ridden, weight of the rider, and his or her riding style. Of course, the battery is equipped with the smart battery management system that protects it from overheating, short circuit or overcharge. As the battery is placed behind the seat tube, your e-bike has better riding characteristics and offers significantly easier handling.

Display

Your e-bike can be easily controlled via the Apache Power Codac contrastive LCD display with integrated controls and many useful functions. The display is very well arranged and is located on the left side of the handlebar. It is here that you will find an integrated USB charger connector for your phone. The control is simple thanks to buttons with which you can select the assistance level or switch between individual cycle computer functions. Besides the riding mode selected, the display shows data such as time, speed, trip made, trip remaining and battery status. You will always have an absolute control over your ride.
