An e-bike is an Electronically Power Assisted Cycle (EPAC), also known as a Pedelec.
An e-bike is an Electronically Power Assisted Cycle (EPAC) by EU legal definition. The e-bike is primarily a bicycle engineered to incorporate a low wattage 250W motor and a lithium-ion battery, to take the hardship out of cycling when needed.
The e-bike must be limited to 25kph, at which point the motor assistance cuts out and pedaling alone propels the e-bike. Any electric bike with a throttle is not classified as an EPAC and therefore is not road legal.
The motor is designed to assist you while pedaling, allowing for the enjoyment and health benefits of cycling, while offering assistance when required e.g. uphill climbs or into a headwind. The fact an e-bike requires 30% less physical effort means longer distances can be travelled than regular cycling. E-bikes have also been shown to encourage the user to choose cycling as an alternative to their car more often than a regular bicycle.
E-bikes manufactured to European standard EN15194 are 100% road legal in the EU and are classified as a bicycle for legal purposes, hence they do not require Tax, Insurance or number plates, unlike e-scooters which are not legislated for in most jurisdictions. No driving licence is required and anybody over the age of 14 can legally ride an e-bike.
