Strictly speaking, you should not ride a vehicle that can fling you off at a speed much faster than you can sprint. They should probably be talking to skateboarders about the fine art of not eating shit.

Each person will have a different maximum safe speed.

> not go 87mph

When this baby gets up to 88mph, you're gonna see some serious shit.

I'm not sure what your stance on non-electric bicycles is but just a leisurely cruise is faster than I can sprint.

And by serious I assume you mean meat crayon.

It’s not the falling that kills you, it’s the sudden stop at the bottom.

Note that's not the actual top speed in use:

"With that much power behind the 22″ wheel, the electric unicycle achieves a wheel lift speed of 140 km/h (87 mph). The wheel lift speed is the unloaded top speed of the unicycle’s wheel when the unit is lifted into the air. It is higher than the actual top speed when ridden on flat ground, but is a useful metric used in the industry for comparing electric unicycles. The actual operational top speed of the V13 is still likely to surpass 90-100 km/h (55-60 mph)."

That article got the units wrong. It should be KPH.

The promotional graphic says 140kph
