Our take on the Firmstrong Siren Lady Single Speed Beach Cruiser Bicycle

The Firmstrong Siren Lady is a single-speed beach cruiser with a women's frame, forward pedal design, and color-matched fenders and rims. It suits riders from 5'4" to 6'4" who want a relaxed, stable ride with extra legroom. The forward pedals let you keep the seat low for easy stops without sacrificing leg extension. Compared with basic cruisers, it offers a more coordinated look and a geometry that accommodates taller riders, though the single speed limits use on hills.

About the Firmstrong Siren Lady Single Speed Beach Cruiser Bicycle

The Firmstrong Siren Lady is a single speed beach cruiser with a 17-inch extended-length steel frame and 26-inch painted aluminum wheels. It has matching color fenders front and rear, and the rims are color-coordinated with the bike. The frame has a circular, high-arching top tube.

Its Forward Pedal Design places the pedals slightly in front of the seat. Riders can keep the seat closer to the ground and still fully extend their legs, which makes it easier to put both feet flat on the pavement at a stop. The 4-inch extended frame adds space between rider and handlebars, for a more relaxed, upright, kicked-back position.

The 2.125-inch wide white-wall tires and the dual spring oversized seat cushion the ride. The handlebars have synthetic leather grips. Seat and handlebar height and tilt can be adjusted to fit the rider. The bike arrives 85% assembled.
