That's a good question, I'd rather like to know myself; It's like a smaller BPM. I wonder how many RPM it can be pushed to until back EMF starts hurting.

BTW, where did you get that particular motor from?

I got these answers from Bafang on my questions :

Can you tell me what the nominal power (Watt) is of this Bafang motor : BFSWX02 48 V (12)
 
Feedback : 350 Wat ,500Wat,750Wat 


What is the number of rotations at max. throtlle ?

Feedback: 340 RPM 

340×23×25.4×0.001×3.14159×(1/60)×3.6=
37.44 kmh and i get in real life 34.5 kmh so wind, weight and drag cost me only 3 kmh which is not a lot.
