It weighs half that, including me, and the average speed over a longer trip is about 33 to 35 Kph. In cities you ride just as fast as the rest of the bike traffic, there isn't any point in trying to go faster, and top speed is rarely achieved, you'd need a 100% full battery and a rider in very good condition. More usual you'll be around 35 to 38 kph in open country where there is very little other traffic.
My 'commute' is 64 km, it takes me two hours on the dot door-to-door.
Using my Stromer ST1X — which lacks the top of the line motor of the ST3 and ST5 — I can bike at 45kph at any battery % above 30.
I am probably 140kg with bike, battery, laptop, clothes, and stuff.
Outside the cities I can go in the bike lane, and I am absolutely twice as fast as most bikes.
I live in the Netherlands, so everything being flat helps.
I recently sold my ST2. I could get only 30-60km on a full (1kwh) battery at max speed (46 kmh). But then why would you go below max speed om a 7k bicycle? I got rid of it because it was also very expensive in maintenance, and because cycling on the road slightly slower than cars really sucks (a few too many encounters with aggressive cars). The stromers are near impossible to ride without assist, think because of the regenerative engine. When the battery was empty or I had one of those weird error 18 things I could go abou 17kmh with a lot of effort. I got a vanmoof bike instead niwy, so much nicer. 30kmh, easy to pedal past assist speed cause of light front wheel motor. Lightweight, 500wh battery is pretty ok (also same 30-60km range). Lots of repairs (under warranty) though, build quality is subpar. My 30km commute is 65 minutes now on my vanmoof, where it was 50 minutes on a stromer.
I don’t have the ST2, but 30km on a full battery seems off to me :)

How was the Stromer reliability wise?

That's a very neat bike and that motor is twice as strong as the one on the Bosch models. What kind of range do you get out of it at 45 kph?
Something like 50/55km on the 800Wh battery.

My concern at those speeds is traction. I prefer fat tires so a bit of loose gravel or a pothole doesn’t ruin my day.
I go at that speed on my road bike under my own power with teeny tiny tyres to reduce drag. By comparison this thing is safer since it has disk brakes and larger tires.
Yeah road bike riding is absolutely what I want to avoid though. Suppose it’s personal preference but I hate those tiny tires. I’ve hit a curve + gravel/loose asphalt and had my front wheel slide sideways causing me to lay the bike down at full speed. Back in my BMX days I had a friend lose his top lip like this and I was riding right next to him (it got sewn back on). And I’m just a casual rider now a days. I’m not a commuter or sport rider, just gets me outside on a nice day. So I am taking in my surroundings and not necessarily 100% focused on the road.
2 1/4" tires on it, traction is pretty good. Haven't fallen yet, had to brake hard for animals (cats, dogs, deer, a rabbit or two, and once a boar). So far so good, but having already had a pretty bad bike accident I'm pretty careful now.
