Fixed with a front brake.

Ride with a 39t chainring and a 17t cog, or a 44t chainring and a 19t cog, for 60-61 gear inches.

Forget about skidding, learn to stop by back pedaling, and use the brake for safety while learning.

Frankly, and with all respect for single-speed riders, I don't understand single-speeds.

They look like a broken fixed gear bike.

Coasting has no value that I can see, although back in my geared bike days, coasting somehow seemed desireable.

Nowadays, riding a bike that coasts would give me the creeps.

I think most single-speed riders would choose fixed if they would only make a two day commitment to fixed gear.

As for flip-flop fixed/single-speed bikes, that REALLY has me wondering.
