I have a class I. It is significantly faster than anyone else on the bike trails around me most of the time. My roadbike will go faster on the downhill sections, but on flat or uphill it is much slower. Because of this it doesn’t fit well on the bike trails - I make it work, but only because the trails are not busy and so the rare times I encounter anyone else I hit the brakes and pass much slower.
