Description
SIMPLE RIDING. ANYWHERE.
The Siren Single Speed is the effortless beach cruiser built for women who want a smooth, stylish ride—no fuss, just fun. Designed with a slightly stretched frame and a relaxed pedal position, it’s perfect for riders between 5’4” and 6’4”, though its comfort-first geometry works for just about anyone.
Why It’s Different
-
Forward Pedal Design: Unlike standard cruisers where your feet sit right under your hips, the Siren’s pedals are shifted slightly forward. This means you push down and out instead of just down, giving your legs extra room to stretch without raising the seat.
-
Lower, Leaner Stance: You can keep the seat comfortably low while still getting full leg extension—great for stability, especially if you prefer feeling closer to the ground.
-
Easy On & Off: The arched top tube dips low, making it simple to hop on and off, whether you’re in a sundress or board shorts.
Built for Relaxed Rides
The Siren’s frame keeps things clean and classic, with just enough modern flair. The riding position is naturally upright, but with your feet kicked forward a touch, it takes pressure off your hips and lets you cruise in total comfort. No gears, no complications—just a bike that feels as good as it looks.
Perfect for:
-
Beach paths and neighborhood spins
-
Taller riders who want extra legroom (but still comfy for all heights)
-
Anyone who wants a laid-back ride with a feminine, timeless style
- 17” Extended Length Steel Frame with 26” Painted Aluminum Wheels and Front/Rear Fenders
- Great recreational riding bike for taller women or those who would like more leg and arm extension. 4” extended frame creates more space between rider and handlebars.
- Forward pedaling design allows riders to keep seat closer to ground while still getting proper leg extension
- Frame Geometry makes riders feel less cramped, creating a more “kicked back,” “relaxed” ride
- Circular, High Arching Top Tube Frame Design
- Dual Spring Oversized Seat for Added Comfort
- 2.125” Wide White-Wall Tires provide a cushioned, relaxed ride for easy rolling
- 28.5” Wide Chrome Plated Cruiser Bike Handlebars with Synthetic Leather Grips
- Bicycle Weighs 43lbs. Fully Assembled
- Fits Most Women 5’4” – 6’4” Tall
- Recommended Riding Speed 3 – 25mph
- Recommended Riding Distance 0 – 35miles in a single trip
- The Seat and Handlebar Height and Tilt can be adjusted to properly fit the rider
