Cycling is fantastic. First thing I did is installing mudguards (full, not the Cowboy design). In the Netherlands this is a must.
Battery life is very decent and as advertised. What's really strange though is that I had quite a few power offs while riding. I. haven't figured out what causes this behaviour, but it's annoying.
Build quality seems to be very good, and the bike looks great of course. A way to power on/off from the bike itself would be a big improvement, especially for those who don't mount their phone while riding (I use a Garmin Edge I use on my racing bike as well).
