App is ok, not a lot of functionality, but fantastic bike. Biggest issue right now is it isn't tracking the hours correctly. I have less than an hour on the bike and it is showing 5:25hrs. Also that it went 82.6mph for the top speed. I am thinking it was tracking while in the back of my pickup??? Not sure. Anyway great bike I hope they advance the software to be as good as the machine.

It gets the job done but I'm sure the app will get better over time. The first major feature I'd like is total ride time on each component. Battery being the most crucial to me. As far as wants, I'm personally excited to be able to get more intricate with power curves. The power is great over 60, but the torque becomes too much to handle in corners at high hp.

Works pretty well for what it is. Still a bit basic, with some key features missing like the throttle response curve etc. They say it's coming though and I'll update my review then. The app looks slick and I really love the dark mode toggle. One thing I wish there were update notes, there have been 2-3 app updates now but no change log so I don't know what's changed, maybe nothing very user facing but would be nice to see a change log to know at a glance. Bike is great.
