No problem, happy to help. The confusing thing is that there are two similar ratings, E-25 and E-50, both of which are recommended for e-bike use. And the search tool doesn’t capture all the newer models. The reality is that the rating applies “for sustained speed” (not ‘maximum’) so to most people using a regular bicycle or even an e-bike with E-25 tyres, 25kph (15mph) is a sufficient average speed for typical use, indeed that’s the speed e-bike assistance is legally limited to on European roads. Most people will exceed that speed downhill, but not for long continuous stretches. The E-50 rated tyres are actually designed to suit use on unrestricted e-Bikes capable of a consistent 30mph which are legal to use on private roads and off-road. Personally, I don’t see any harm in equipping my eBike with the best tyres. But you may wish to shop around; I would suggest that any E-25 rated tyres will be suitable for most ‘normal’ cycling, the choice will be more about selecting between the intended main use: off-road, touring, fast road, gravel etc.
