Electric Bike Laws 2016In 2015 there was an amendment to the "Electrically Assisted Pedal Cycles (EAPC) which stated that electric assisted bikes that are limited to 25km/h (15.5mph) while equipped with a motor that does not exceed 250 watts are exempt from motor vehicle legislation and do not need what is known as "Type Approval"
This means any e-bike that complies with these rules are usable without the need for tax, registration and insurance and still be fully road legal.
Link to those rules can be found here
HOWEVER as of January 1st 2016 it has been deemed that any electric bike bought from there on, that can be powered solely using a "twist and go" throttle will have to go through type approval. If the Twist and Go throttle does not exceed 15.5mph it will not be treated as a motor vehicle according to the law and will not require to to wear a helmet, registration, insurance and even tax.
This being said the new law will not affect any electric bicycles that have been bought before January 1st 2016 due to whats known as acquired rights (grandfather rights) this means that new rule cannot be applied to something made before the due date of the rule being applied.
The rule about "Twist and Go" throttles does not apply to walk assist throttles (ones limited to 6km/h) therefore this update to the law will not affect those types of throttles.
