What were you lot doing on your bikes when you were young if you didn’t even master the wheelie
Riding XC. One of my mates had a riding buddy across the road – they both got very good at wheelies and things. When the kids start to learn, I’ll have to knock my hours down so I can hang around with them lol.
In terms of the physics of it, you can:
1) pedal harder to get it up.
2) pedal less to let it go down (these two give a pretty limited window)
3) move the bike forwards and backwards to keep your cog over the cop of the back tyre’s interface with the road.
Essentially if you can do a brakeless manual, the physics are the same as 3).*
* I can’t do any sort of extended manual, and my wheelies are mediocre at best. But I assume this is a theory lesson.
