Description

SIMPLE RIDING. ANYWHERE.

The Firmstrong Siren Lady 7-Speed, formerly known as the Chief Lady, is the ideal beach cruiser for women who want the classic look of a cruiser with the added performance of a multi-speed bicycle. Although the frame measures 17 inches, its extended length and 4-inch forward pedaling design make it a perfect fit for taller riders between 5 feet 4 inches and 6 feet 4 inches. However, because of the unique geometry, it remains an exceptionally comfortable choice for riders of all heights who value stability and a little something extra from their cruiser.

The standout feature of the Siren is the forward pedaling setup, where the pedals are shifted 4 inches in front of the rider's hips. In a traditional design, you push directly downward to pedal, but the Siren allows you to push slightly down and forward. This creates significant added leg room for taller women without needing to raise the seat to an uncomfortable height, providing full leg extension while keeping you lower to the ground. This laid-back riding position allows you to maintain a straight back while having your feet kicked forward, effectively taking the pressure off your hips and providing a greater sense of stability during your ride.

With the addition of a Shimano 7-speed gear system and front and rear handbrakes, the Siren Lady is much more versatile than a standard beach cruiser. These gears allow you to tackle hills and handle long-distance rides with ease, making it perfect for commuting or getting exercise. The frame design is clean and sleek, featuring a high-arched top tube that dips low to ensure getting on and off the bike is simple and safe. The Siren Lady 7-Speed is a long, elegant cruiser designed for women who want a high-performance ride that feels comfortable, stable, and feminine whether they are cruising the boardwalk or city streets.
