Single Speed Bikes

A single speed bike is a bicycle with only one gear ratio—no shifters, no derailleurs, and no front or rear gear changes. Because there's nothing to shift, single speed bikes are simpler, lighter, lower-maintenance, and easier to learn on than geared bikes. They're a popular choice for kids' first bikes, BMX riding, and casual neighborhood cruising. Almost every Glerc bike in this 12"–18" collection is a single speed bike for that reason.

Yes, single speed bikes are ideal for kids, especially beginners. Without gears to learn, children can focus on balance, pedaling, and braking instead of worrying about shifting. Single speed bikes also have fewer moving parts that can fail or need adjustment, so they stay rider-ready longer. Most Glerc bikes for ages 2–10 are single speed for exactly this reason.

Both share the same drivetrain principle—one gear, no shifting. The difference is in how they're built: A single speed cruiser bike has an upright posture, swept-back handlebars, and a low step-through frame for relaxed neighborhood riding. Our vintage girls bikes (Little Miss, Little Molly, Sasha) fit this style. A standard single speed bike (like Cosmo, Bilbo, or the BMX-style Starry, Pongo) has a simpler frame and more classic geometry, designed for everyday use. Pick by where and how you'll ride.

Yes, significantly less. With no derailleurs, shifters, or shift cables, single speed bikes have fewer parts that can fail, slip, or need adjustment. Routine care is mostly chain lubing, tire pressure, and brake checks. For even lower upkeep, our belt drive single speed bike—the Nova—replaces the chain entirely with a clean, oil-free carbon belt. Great for parents who want a no-fuss ride.
