Wanted to give an update on this. I had my Vado sl 4.0 eq updated today at my dealer. I got the bike home and started a ride. The chain promptly jumped off the chain ring. Went back to the shop because the chain was stuck in between the motor housing and chain ring and I didn’t want to tear up the paint down there. They got it back on the chain ring and when I got home I started another ride and within a quarter mile it came off again. I rode this bike 250 miles or so with zero issues before the update. Now the chain has come off twice in less than a mile. Called the LBS back and they put in a message to Specialized. They think it could be the update. They also think Specialized could end up replacing the chain ring. Today was a long day needless to say. Anyone with this bike may want to wait before they update theirs.
