Be at one with our single-speed cruiser

This is a whole new breed of one-speed bikes. Our Retrospec Siddhartha is designed for the modern, urban, hybrid rider. With its retro appeal and superior performance, it’s among the best single speed bikes available. Leather grips, mustache handlebars, and a leather saddle provide the comfort of a beach cruiser, while the track bike frame provides an aggressive ride for urban excursions. We’ve eliminated all of the cables and wires that show up on most bikes. We’ve made our Siddhartha single-speed cruiser as sleek and minimalistic as possible.

The Details

The Siddhartha SS features KT coaster brake hubs, so you can coast and brake with your feet, just like on a beach cruiser. Front and rear wheels come with 32 spokes, and are built with lightweight 30mm Deep-V rims for a comfortable ride. A resilient nylon rim tape and CST Super-HP tubes and tires (700x32c) are durable and smooth rolling. All Siddhartha one speed bikes come with a flat top tube and angled fork for a traditional track-style frame.

We strongly suggest that you take your bike to a professional bicycle mechanic to be built and/or checked out. Incorrect assembly of your bike could result in premature wear and/or failure of individual components. The brakes and derailleurs are not yet set up and need to be properly adjusted in order to stop and shift correctly.
