Z20 batteries

The new Z20 system is available in combination with different battery types. These vary in capacity, size and shape.

External battery

Easy-to-remove battery, e.g., for charging at home
The pedelec can be used as a normal bicycle – riding without battery

_{* Realistic data for 100 W rider output and favourable conditions: Riding in assistance level 1, Eco mode, flat terrain, 70 kg additional load, incl. rider, under optimal conditions greater range possible.}

Battery V2

Capacity of up to 612 Wh for ranges up to 145 km*

Battery V5

Capacity of up to 500 Wh for ranges up to 120 km*

Semi-integrated batterys

Slim design – the pedelec looks like a "normal" bicycle

Battery V7

Capacity of up to 500 Wh for ranges up to 120 km*

Battery V8

Capacity of up to 625 Wh for ranges up to 145 km*

Energy recovery

Activation of the motor brake when riding downhill
Increased range
Reduced wear and tear on the brakes for greater durability

How recuperation works

It is well known that opulent braking generates a lot of heat. In a car, for example, the tyres would start to smoke. However, this should not be underestimated with bicycles either. The tyres also become very hot during a strong braking manoeuvre. An electric motor that has the ability to feed energy back into the motor when braking instead of letting it evaporate uselessly in the environment can assist the battery longer. Hub motors such as our neodrives rear motor can be optimally used for this purpose. In principle, it does not matter whether the motor is located in the rear or front wheel, but in most cases the motors are located in the rear wheel. A bottom bracket motor, on the other hand, where the rider acts directly on the bicycle chain, is not able to recuperate.

Technical data

Cell technology

Lithium ions

Battery position

Down tube, seat tube or luggage rack (depending on battery type)

Voltage

36 V

Capacity

14 Ah to 17,5 Ah (depending on battery type)

Energy content

500 Wh to 625 Wh (depending on battery type)

Weight

Approx. 2.2 to 4.0 kg (depending on battery type)

Power supply

Additional electric loads, e.g., headlight 6 V / 3 W

Charging

On the bicycle or removed from the bicycle

Battery charger

4 A charging current for fast charging: charging time for the 500 Wh battery is approx. 3 h
80 % of the battery capacity is already restored within the first half of the charging time. Gentle charging for a long battery service life.

Rear motor

The completely redesigned Z20 rear motor is highly efficient. Positioned on the rear wheel for a harmonious and agile ride.

LCD

The LCD is the interface between the drive system and the cyclist. The Z20 system offers two LCD variants.
