Right wheelie school time….(for those interested)…
Pick a low gear, say middle ring at the front, 1 down on the back.
Lower your saddle a little from normal riding height, say 30mm.
Pick a pancake flat bit of road/grass, or a very slight uphill incline.
Pedal along at a slow walking pace.
Put a finger on both the front and back lever. Very lightly engage the back brake so that you can feel the slighest of resistance.
To lift the front, push down on the forks then use their energy to make lifting the front easy, then its a quick pedal stroke and pull to get the front up. Aim past 45 degrees, the balance point is higher than you think normally. Once the front wheel is off the floor match the pressure on the back brake with the front brake so both hands are equal in terms of their pressure.
Think smooth pedal rotations and steering is mainly via your knees, which sometimes help if they are pitched outwards a little (think knees pointing outwards as soon as the wheelie starts). You use the rear brake and pedalling to keep at the balance point, if you pedal too much, squeeze the brake, if your not pedalling enough the bike drops anyway. Going over the back is no big deal, provided your not clipped in (SPDs aren’t helpful for wheelies). Just land on both feet and squeeze the back brake to stop the bike.
Then practice, practice, practice…..etc. It does come.
