There’s a particular hill a few km from home that the old scooter would have struggled to climb. The new scooter was doing 8 kph at the start and had accelerated up the hill, sitting on 10.5 kph as it approached the crest.
It was equally steep on the downhill so I let the thing have its head and hit 13.6 kph going down it. On the flat it can just exceed 11 kph.
