Try to put your stronger leg at 9 o'clock (rear), that's the important one. Sometime, clip or strap on the front would help... Someone suggested to try with lifting the rear, locking it up and putting it down... I personally believe it is too dangerous. (Ask me how I know). Don't go crazy with this. Safety first. Once you try enough stopping with weight forward, it will come to you naturely.
A lot of it depends on the bike and tires. My buddy had a fixie with really burly commuting tires and neither one of us could get it to skid unless we were on marbles or gravel somewhere. Make sure and throw your weight forward, it feels like you are going to fly over the front, which is not a good feeling. Keep trying though, I'm sure you will get it!
Ok first of all what gears are you running. Think logically a lower geared bike will be easier to skid then a higher geared bike. Before I switched my high gearing for a low gearing on my bike I had a hard time skidding. Also like stated previously what kind of tire are you running. But most importantly what kid of pedals are you running. I run spd clipless pedals and they make all the difference not only can I shift my weight forward, stop my rear foot, but I can also I can pull up on my front foot to initiate the skid. Actually I compromised some speed for stopping power by going with a smaller gear. Now to skid I put my weight forward and if I want to stop in a small distance I just skid with my weight still over the seat. This is only possible because of the middle range gear and the clipless pedals.
like some others have said, focus on lifting the pedal with your front foot rather than pushing down with your back. for me, it was an 'ah ha' moment when i stopped trying to force my back foot down to skid
Sorry to revive an old thread but i broke down and got myself a fixie. I figure i dig bikes and have been SS'ing for quite some time so why not try sumpin new. My first ride was yesterday and i too am having a hard time skidding. I currently ride a 49T front 17T in the rear. Should this gear be easier or harder for a fixie newb for skidding. Since everyone digs picks...here's my new ride. Bianchi pista w/ decals removed, 165mm FSA carbon pro cranks and Velocity deep v wheels on flip/flop formula track hubs (fixed/fixed).
Two tips I have for people when first learning to skid:
1.) Be forward. Far forward. Like nuts-to-the-stem forward.
2.) PULL UP with your forward leg. Pushing down with the back comes naturally, but if you're not utilizing your forward leg, you're wasting half your legpower.
Consider what handlebars you have. Bars that move your hand position forward, like bullhorns/flop&chops will make it easier to put your weight farther forward. If you have normal drop bars, putting your hands on the tops of the curve will move you forward. Track drops, you're kinda SOL. Flat/riser bars will feel the weirdest, so just concentrate on being nuts-to-the-stem forward and be careful, since controlling the bike with a setup like that will feel weird.
Make sure your straps are tight enough that you don't have lots of slop. If you have plastic clips, I recommend throwing them straight in the trash can and getting some nice steel clips.
I wanted to say thanks for all the advice so far. I've managed to learn the skip which has helped me out a little bit but I'm thinking my gear ratio (49/now 18) is makes it tougher to skid unless i'm going REALLY fast. Either that or i'm a super wuss.
Well at least my gear ratio gets me around town faster. Just have to pay a lot more attention to my surroundings
