It depends where you are riding. Going uphill is a no-no. Big gears, a flippy floppy front end and its weight make it rather unpleasant. On the flat its OK- quite comfortable as long as the trail is quite smooth and flowing. Bottom bracket is quite low so pedal strikes canbe an issue. Downhill its brilliant- stable and the rotational weight of thise wheels (14lbs rear and 11lbs front) act like flywheels and help keep it going. Brakes are piss poor though so you have to ride with big commitment. The slack head, long wheelbase and low BB all help to keep you out of too much trouble if you decide to go for it.
