Apparently out of the box some at ES were going to 36v on the Velomini another clone of the beat bike. The in built battery is a 5s 6 ah going of the charge voltage.
If you did not want to fold with the battery on it, then yes fairly easily just make a pack to go in the V as there is a stack of room there, just fit a plug and lift out the battery to fold, I was going to say no way until I went and looked at it
I have had mine over 60kph in a full tuck down hill.
I not suicidal enough to try it but I can think of a way to get 6000w to the rear wheel, you would lose folding though.
and probably need a carton of tyres.
