Hi Andrew, with your current setup you will be hitting somewhere around 55km/h. Now don’t get me wrong this setup will work just fine on the esc you have but most likely not very well on a Vesc as of the erpm limit.
Now if you were to switch to a 190kv motor your top speed would be around 40km/h (I am just using 15/36 gearing and 90mm wheels as a reference). And you would be well under the erpm limits of the Vesc.
Option number 2 with the 190kV motor is obviously the better choice but 1 will still work and you might as well try that first if you have the parts for it already. If you choose to lower the motor kV to 190 there are a few good options out there such as @torqueboards motors, @JLabs’s, Ollin’s and then some cheaper but well used and reliable hobby motors like the Sk3 motor range and even the Keda motors are proving to very good considering the price. (I have used keda motors on both of my builds and they are rock solid. One of my mates ran the board into a concrete block at 30-40kmh because he forgot that the range drops out after a while so he had no brakes to stop it again, all that happened were some minor marks and scratches.
Good luck with your build mate
