@dcosmos I would shoot a video showing me going 25+ on my V1 but I sold it. Perhaps I can borrow one from someone in the PDX area? I have screenshots of the app, but I know those could potentially be doctored. When I get my plus on Friday I plan on seeing how fast I can get it going.
There's really no trick to it, just find a mild hill with extremely smooth pavement and no cross-traffic concerns. Slowly ease your way up to speed going downhill. Once you get past about 18 you have to start putting more focus into balancing since the motor will no longer be able to do 100% of that for you (which is why some people have issues with nosediving at higher speed). When you want to slow down just lean back really slowly and bleed off speed. The reason this works is that while the Onewheel's motor alone is not capable of exceeding something like 18 mph you can use gravity to carry you way past that point and let the Onewheel just help with the balance. The first day I tried that I got up to around 23mph and the second day I got to 26.4mph (which is my top speed). I could probably go higher but I'd need to find a longer stretch of road, and there isn't much point since at the time the leaderboard was rejecting speeds that high (FM said they are working on fixing this).
No conspiracy. Try it yourself at your own risk.
