# [EU] Fucked by police / need help by calculating max speed

Got fucked by police in Munich. They took my board with them.

ERPM 10.000 with 97mm wheels is how much km/h?

Should be around 20kmh. I think. Thatâ€™s really bad. I am sorry man.

are u shure? 47.000 is around 40km/h

I guess itâ€™s 8.?? km/h.

Got to know gearing rightâ€¦?

With this gearing it should be around 10km/h

Anywaysâ€¦ A 15/36 gearing would give a top speed around 10 km/h

Noooooo! And now you have to pay a fine to get it back?

not sureâ€¦

I came to 2.7km/h

97mm*3.14 = 304mm

10.000 u/m / 7 pole pairs = 1428,57 u/min

1428,57 u/m * (15/40 gearing) = 535,71 u/min

535,71 u/min * 0,304m = 162 m/min

162m/min / 60 = 2,7 km/h?

Just use the Esk8 calculator and see the top erpm and top speed. Then do the ratio

Typical, instead of hunting down thiefs, killers and rapists they bother normal citizens for doing harmless stuffâ€¦

You go to them and show them how slow it is, with police mode on feather remote of yours xD

Noâ€¦ the speed is 2.7 km\h. Set in the VESC. Think about it.
