Most motorcycles have fuel range of 200 mi.
In between those 200 miles, most likely a rider would stop for food, drink, bathroom breaks, etc..
Not many trips require a rider to sit in the saddle for 2hr. + without stopping.
For many urban areas, 2 hr. + should cover distance of 80 to 100 miles.

For ebikes (or bicycles), 2hr. sitting in the seem rare (to me) without stopping.
Unless you're doing errands good 30 to 40+ miles away.
Let's say you have a battery range of 35 mi. and recharge for battery is 3-6 hours.
To travel 30-40 miles would require at least one recharge.
2 hr. riding plus 3-6 hours charging time every 30-40 miles.
I think until the battery tech advances to allow longer range or the roads are converted to able charge-as-you-ride,
ebikes are not meant for long distance travel in a single sitting.
But I'm happy with ebikes taking over the task of riding my motorcycle on my 10-12 mile one-way commute on a daily basis.
