Anyway, I'm trying to say just because 10 or 15 mph makes sense for the bike trails, doesn't mean it's ideal for an ebike that is trying to survive on the street.
It's an infrastructure problem.
If you are very lucky you find 3 types of infrastructure:
1. a road
2. a bike trail
3. a footpath
On 1) the spped limit is 50km/h in cities and 100km/h outside
on 2 the average people drive 10km/h to 20km/h, very few do 30km/h
on 3) the average speed is 3km/h
If you want to use this infrastructure you have to be in the same speed category.
So if you want to ride on the street you should be able to do at least 50km/h which translates to an (electric) motorcycle, a type of vehicle that exists.
If you want to use #2 youhave to stay within those limits. Motorcycles usually(!) are not allowed on bike paths for good reason. Why should electric motorcycles be allowed? There is NO reason for that? Zero emission next to a busy road has zero relevance for other cyclists.
It would be perfect if there would be an infrastructure for 30-60km/h "light vehicles" which could include e-bikes, but in reality we often don't find even all 3 options above (often bike and foot path is mixed so you have a speed between 3km/h to 20km/h and most fast bicyclists are not even able to ride 30km/h because of all those people moving much slower on the same lane), so it will stay a dream that we will see nation wide 4th grade of infrastructure.
You have to decide on which side you want to ride:
using the road requires a motorcycle.
using the bike lane requires a bicycle and requires bicycle speed.
Btw the infrastructure problem is exactly the biggest problem that our fast s-Pedelec class faces. Those s-Pedelecs usually drive around 35-40km/h which is to fast for bike pathes (they are not allowed there but you most likely will get away using them at reasonable speed) and they are to slow for many streets with lots of traffic at 50km/h+
