Just updating the review of my 2020 Vado 3.0...
I've hit the 2000 mile mark. I still have a quiet chain and haven't needed to lube it yet. After the initial break-in of the spoke true, I haven't had any true issues either.
I'm averaging 80% battery drain on a 17.5 mile commute at about 22-23 average mph, turbo 100% boost on both slidebars (Mission control app)
If I take it on a leisurely ride, I can ride 30-40 miles with less than 50% battery drain. (15% boost and up to 100% only as needed for incline assistance)
Very steep hills are not a problem at slow speeds, lowest gear. 100% assistance.
I found that both Axiom and Ortlieb QR panniers work well with the rack.
The fork-mounted headlight is very bright, but it constantly losses it's aim (pivot will not tighten securely)
