Lion
The lion achieves a maximum velocity of 80 kilometres per hour in short bursts, typically lasting no more than one minute before requiring extensive recovery. This impressive statistic is somewhat undermined by the fact that lions spend approximately 20 hours daily in a state of profound unconsciousness. When awake, they display a marked reluctance to move unless food presents itself within pouncing distance.
Bicycle
A standard bicycle maintains 25-30 kilometres per hour indefinitely, limited only by the cardiovascular endurance of its operator. Professional cyclists regularly exceed 70 kilometres per hour on descents. Unlike the lion, the bicycle requires no rest periods, consumes no zebras, and can be legally operated on public roads in most jurisdictions.
VERDICT
Whilst the lion's burst speed exceeds that of most cyclists, the bicycle's sustained performance and lack of mandatory napping make it the superior choice for actual transportation. One cannot commute to work aboard a lion without significant legal complications.
