The battery of a pedal assisted bicycle stores electric energy. It can be recharged in any socket with a suitable charger (laptop type). Currently most manufacturers integrate Lithium batteries, into our models, as they have no memory effect and are much lighter (2-3kg) than other materials like Nickel and Lead.

The motor of an electric bike is usually integrated into the hub of the front or rear wheel, and the maximum power is allowed to develop is 250W. Depending on its configuration they can be classified like direct transmission or gear, being the second ones lighter and smaller than the first ones.

The pedal assistance sensor is located in the bottom bracket and detects that the user is giving pedals. It works by sending a signal to the controller to adjust the level of power assistance as a function of the pedaling cadence (rpm) and torque exerted on the transmission.

The control panel displays the status of the battery charge to the user, and it also allows to select the desired level of assistance. In some models it is also possible to configure the specific settings of the electrical system and access to some data such as distance traveled and average speed. There are basic control panels with just some leds and other more complex with a LCD digital display and multiple functions, or even mobile APP via Bluetooth.


The General Vehicle Regulations (Real Decreto 339/2014) defines an electric bike or pedal-assisted bike as a bicycle that has a motor with a limited power under 500W which helps the user when pedaling. The motor must not work if the user stops pedaling or when the speed exceeds 25 km/h.


As a complement, the European Directive on type-approval of two or three wheels motor vehicles (Reglamento EU 168/2013), limits the maximum rated power 250W.


All our FLEBI ebikes and components have CE certificate. They have been validated, certified and approved according to international standard EN15194:2017 EPAC regulating vehicles (ElectricallyPowerAssistedCycles), ensuring compliance with the strictest levels of safety and quality.
