About the bikes


There are many reasons why thousands of customers choose to cycle electric, the majority are seeking freedom for traffic, high petrol costs and parking costs. When you consider the total expense of driving on your time and wallet, an Electric Bike becomes an incredibly practical and affordable option for commuting. Others really enjoy or enjoyed cycling and it many benefits but do not feel fit enough or enjoy the effort of climbing steep hills and strong winds. They choose an electric bike to enjoy the journey without sweating but still staying fit.

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.

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.

About the motors


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.


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.
