Bosh makes mid drive motors that support 20mph to 28mph, which meet the govermental regs of Class 1, or 3 ebikes
I don't know the unit on the Firefly.
It looks like an older Bosch CX unit which was their most powerful. I believe limited to 25kph but very easy to take away the limiter.
If I had that Firefly, def would have the 75nm motor and limiter gone

He was probably pushing 300 pounds and I wouldn't have fared well in that head-on crash.
We're a second home resort location so this is more true than many other places, but many people renting these ebikes haven't ridden a bike since they were 10 years old so their skills are lacking too.
Yesterday I was pushing hard near the end of a 4 hour ride, on the flat, and a fellow on an ebike passed me like I was in reverse. If he was speed-limited to 15 mph he wouldn't have passed me.
IIRC the Bosch unit Firefly is using is only 250W and is made for those speed limited pedal assisted bikes. I'm glad Firefly is working on making these available!
