As the "electrically assisted pedal cycle" category was so new, there were no existing vehicles on the market that would meet the standards prescribed by the new legislation. However, it imposed a number of restrictions that limited the performance of any vehicle that would qualify under the new standards. The maximum legal speed of the vehicle would be limited to only 15 miles per hour (24 km/h); it could not weigh any more than 60 kilograms (130 lb), including the battery; and its motor could not be rated at any more than 250 watts.[25]
