Is it permissable for a female to ride a motorbike. I thought there may not be anything wrong as the women in the prophet's(pbuh) time used to ride horses and that would be a similar concept...?

A female is required to conceal the form and shape of her body to the best of her ability. That is not so when riding a horse due to the unique movement of the horse. Rasulullah (Sallallaahu Alayhi Wasallam) said, ?Allah?s curse is upon females on saddles (of horses).?

The Shar?ee prohibition for a female riding a motor-bike may be understood from the analogy of riding a horse. The situation of Dhuroorah (need) may grant a leeway. However, that is not the general situation today as modes of transport concealing the form and shape of females are well available and common.

and Allah Ta'ala Knows Best
