Z20 batteries

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

Neodrives Z20 external battery

External battery

  • Easy-to-remove battery, e.g., for charging at home
  • The pedelec can be used as a normal bicycle – riding without battery
  • Capacity of up to 612 Wh for ranges up to 145 km*

* 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.

Neodrives Z20 semi-integrated battery

Semi-integrated battery

  • Slim design – the pedelec looks like a "normal" bicycle
  • Capacity of up to 500 Wh for ranges up to 120 km*

* 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.

Energierückgewinnung beim Bergabfahren

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.

Neodrives Z20 battery charger

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.
