As with most other provinces, the Nova Scotia Motor Vehicle Act defines a power-assisted bicycle as a bicycle with an electric motor with 500 watts or less and a maximum speed of 32km/h. Electric bikes are permitted on trails or the road as long as you wear an approved bicycle helmet. They do not have to meet the conditions defined within the Canadian Motor Vehicle Safety Regulations for a motorcycle, but they do have to comply with federal legislation that defines Power Assisted Bicycles.
