An electric bike is very different from a regular bicycle. It consists of several electric components such as a motor, a battery and a controller integrated into a design. The e-bikes wheels, frames, tyres, braking system and overall design are purpose-built to accommodate electric components, stability and safety. Therefore, just converting a normal bicycle with electric conversion kit may not be safe.
E-bikes are also called pedelec bicycle where the riders pedalling is assisted by an electric motor. 1:1 Pedal assist system (PAS) in an e-bike activates motor only when the user pedals the e-bike. The PAS motivates the user to pedal naturally and helps you get that calorie burn.
In Australia, legal E-bikes must comply with the European Standard for Power Assisted Pedal Cycles (EU standard EN15194:2009 or EN 15194:2009+A1:2011) and the motor power must cut out (stop operating) automatically when the speed reaches 25km/hour.
As a customer always ask the seller if the E-bike is compliant to EN15194 standard and they have secured import licensee before importing to avoid a costly mistake.
