Excerpts from session reports related to this document
GRB | Session 65 | 15-17 Feb 2017

14. The expert from EC introduced draft amendments on powered cycles (GRB-65-09), including definitions of new subcategories L1-A and L1-B, with a view to aligning Regulation No. 63 with the EU legislation. The experts from Germany and the Netherlands pointed out that the overwhelming majority of powered cycles were electric and questioned the need for the proposed amendments. The expert of Japan called for a prudent approach when and if introducing new categories of vehicles, because other Regulations might be affected as well. GRB was of the view that more time would be needed to study the proposal and invited the expert from EC to issue it as an official document for the next session.
