When first riding a fixed gear, a cyclist used to a freewheel may try to freewheel, or coast, particularly when approaching corners or obstacles. Since coasting is not possible this can lead to a "kick" to the trailing leg, and even to loss of control of the bicycle. Riding at high speed around corners can be difficult on a road bike converted into a fixed-gear bicycle, as the pedals can strike the road, resulting in loss of control. Proper track bikes have a higher bottom bracket to compensate for the constantly spinning cranks and largely mitigate this problem.
