Hate to double post, but may I repeat what I put down to almost exactly the same situation earlier:
Wobbly stops are mainly caused by nerves, and using the wrong technique
in a few crucial ways is going to land you on the ground. The good
news is, the worst that happens is severe embarrassment and minor
bruising (plus some minor bike damage). The bad news is it knocks your
confidence even more, and makes every stop a thing to dread throughout a
journey - sapping concentration in the meantime.
certainly were feeling a bit nervy at the stop, you had to stop a bit
more suddenly than you expected, you grabbed the front brake, and you
were looking directly at the ground that you were about to hit.
Is that right? Please try these suggestions:
Do not grab the front brake at all, have one finger on it at the most.
Do all your controlled braking with the back brake only, particularly
for the final few yards.
- Stop with the back brake, and stick your left leg out as the bike comes to a halt, looking dead ahead.
Try using only the back brake on all walking pace maneuvers, including U-turns and slow corners (whether flat, down or up-hill), and you'll have an entirely different outlook on slow speeds and indeed bikes altogether. And no, this isn't hyperbole!
