Quick comparison between my S1 and S2
Kids are in the background so please forgive the noise, my wife put one of our boys on time out halfway through the video lol.

All and all I feel the S2 is a great step up from my modded S1 and significantly different from a stock S1. Feels like a whole different bike that addresses every area that could have been improved in the S1 design.

I forgot to circle back to my 18 mile ride. At the end of it (going up and down two steep hills for a 3rd of the 18 miles) I had 33% battery life still on mode 4 (unlimited) riding the throttle hard the whole time.

DM me about the S1 😉
