Fancy that; the Level.2 is the one I got too! I have 350 miles on mine so far. It needed the typical shift cable adjustment after a month or so (as cables stretch a bit when new) but other than that, tires and chain, it has needed nothing. I got mine after seeing it at the local Indian motorcycle dealer; I saw they had a sign that they have eBikes, so I ducked in. I didn't expect them to have anything of quality, but the Aventons are NICE.
I'm a little surprised at how easily it rolls. The tires seem kind of fat, but are rated up to 60 psi and are marked as being for moped duty. I keep them at 50-55 psi; haven't had the guts yet to pump them to 60. I'm also impressed with how smooth and strong the hydraulic brakes are. I commute on mine most days, occasionally taking another eBike to keep the battery active.
Like you, I found that it is easy to cruise at 20 mph, even in PAS 1. This morning, I was going up a very slight uphill against a 10 mph wind and going 17 mph in PAS1. No sweat, but a decent amount of work.
I posted a couple videos and a lot more detail on the bike and how I wound up setting it up in
this thread in an eBike-specific forum.
