Jump off
You step or jump off the wheel at low speed and land running. Controlled. Intentional (or at least recoverable). Your feet hit the ground before anything else does.
When it works
At walking speed to maybe 15 km/h (9 mph). You feel something wrong - wobble, loss of balance, obstacle - and you step off. Your momentum is low enough to run out. This is the ideal dismount when things go sideways.
When it doesn’t work
Above 20-25 km/h (12-16 mph), you can’t outrun your momentum. Trying to “jump off and run” at 40 km/h (25 mph) means your feet touch down at 40 km/h (25 mph) and your body goes forward. That’s not a jump off anymore - that’s a crash with extra steps.
555 take
Practice stepping off at low speed until it’s instinct. Know the speed threshold where jumping off stops being viable. Above that threshold, your strategy changes from “bail” to “ride it out and decelerate.”
