The "Surly Pugsley" is our mult-use trail bike and perfect for sandy trails. The huge but extremely lightweight tires make for a joyful ride on all terrain.  The feel of the road under those wheels is one of confidence. The soft tires provide a great suspension system and single speed gearing make for a trouble free ride. Cruising speeds are around 6-8 mph and the balloon tires barely leave a mark.
But the real reward is that this bike allows average bikers to relax and casually explore the woods and swamp with ease.
