Brisbane has the lowest percentage of female commuter cyclists of all Australian capital cities.

Just 18 per cent of the city's commuter cyclists are women, according to 2011 Census figures, which the Brisbane CBD bicycle users group says points to a deficiency in off-road bikeway options.

However, Brisbane City Council maintains it has invested heavily in cycling infrastructure in recent years, expanding the city's network of bikeways to 1100 kilometres, 630 kilometres of which is off-road.

Public and Active Transport chairman Peter Matic said council audits showed cyclist numbers were steadily increasing across the city, growing by eight per cent each year.
