Es2 owner
 

I bought a "used" ES2 in June 2019. I have put 180 Miles on it, mostly downtown Detroit. In the last roughly 10 miles, I can feel the upright stalk starting to loosen. I'm going to get my Allen wrench and tighten every screw.
I have had the "break" fault happen when I hit bigger bumps. The power gets restricted, but I'm able to hit the break briefly and continue on my way. I'm a little worried that one time the power is going to cut out and the break might throw me off the bike. Had anyone else have this happen?
