How does it work

The main difference with ordinary bicycles:are the two components that make up the electric system, a motor and battery.

When you start to pedal the motor is turned and it gives you a boost of power. There is a sensor which measures the effort you are doing, so, the more effort you put in the more power is sent to the motor . You can choose the intensity of the power with different levels of assistance. But if you do not pedal the motor will not provide you with any assistance.

For instance, with an electric bicycle the time taken to reach 20kms/h from a standstill is halved compared to an ordinary bicycle with far less effort in comparison.

Who are electric bikes suited to?

  • For those who would like to improve their fitness gradually.
  • For those who want to avoid traffic and the expense of a car

How do I charge the battery?

Depending on the battery capacity it will take between 4 and 6 hours.

Most users charge their battery over night which is perfectly OK as long as the charger is disconnected after the overnight charge .

The BH and most Kalkhoff models require to take the battery off before charging up , Promovec bike batteries as well as Kalkhoff Impulse batteries can be charged up directly on the bike or taken off .

What is the lifespan and warranty of these batteries

BH and Kalkhoff offer a 2 year warranty on their batteries while  Promovec offers 1 year

Depending on the models the lifespan at full capacity is between 600 and 1200 charges.

In terms of mileage the “up to” figure approximate figure  is  30 000 kms at full capacity , before dropping to 80 %  or below.

It is advisable to maintain the batteries in a dry place when not in use at an ambient temperature (18 degrees celsius).

It is also recommended to charge and discharge the battery down to 10 % for the first five charges if you can.

If the battery is not in use for a prolonged period of time, make sure that you give it a full charge every month before leaving it be so that it does not go in low voltage mode.

What types of battery are used?

All our electric bikes come equipped with Lithium batteries . This battery chemistry does not suffer from the memory effect, I.e, you can charge it whenever you feel like it . .

Kalkhoff use Panasonic ( 8Ah up to 24 Ah capacity), Impulse (11Ah up to 17Ah Capacity) and Bosch (8-11 Ah capacity)

BH NEO use Samsung (9Ah Capacity)

Promovec use Panasonic cells (7Ah up to 12 Ah capacity)

What it is an electric motor?

An electric motor is an electric machine which turn electric energy into mechanic energy. It can have several advantages in contrast to combustion engines:

  • At the same power the size and weight are less.
  • Its performance is very high (typically about 80%, increasing it as it increases the power of the machine).
  • It is quieter than a combustion engine and it has less vibration.

What is the Brushless motor?

A brushless electric motor is an electric motor which does not employ brush to make the change of polarity in the rotor. Nowadays, thanks to electronics, are very advantageous because they are cheaper to produce, weith less and require less maintenance.

Other characteristic is that for dosing the power of an electric motor, in the absence of a mechanical accelerator such as combustion engines, the drive is used. Otherwise would obtain any or all of the engine power. These motors are powered by batteries that are independent of power.
