Layer 1

Perfect for any ride

The perfect balance of comfort and speed, we make everything 'just right' on the Centauri S. A joy to ride, the Centauri S is comfortable, sporty, powerful,  lightweight and responsive. 

"S" is for Stepthough…but it’s more than that. Our stepthough frames have a different fit than the step-over counterparts. The S/M Stepthough fits riders looking for lower standover and a more relaxed position, with a taller bar height offering a more upright seating position. The L/XL Stepthrough has a similarly low step-over height, good for riders with reduced hip mobility, while the seat tube height is extended by 4cm to offer a great fit for riders with long legs. All in all, the four sizes of Centauri and Centauri S can fit riders from 4’9” to 6’4”.

One of the benefits of an ebike is that you don’t need to focus on getting the exact-right size to maximize pedaling efficiency - the bike is plenty efficient for you! We’ve chosen two sizes for each model that should comfortably fit most people. That said, you still want to choose the one that’s best for you! A good rule of thumb is to compare your inseam measurement (taken wearing shoes you are likely to ride in) to the standover height of our various models.

The S/M Centauri will fit riders from 4'9" to 5'8" and the L/XL will fit riders from 5'7" to 6'4"

Simple Shifting

Simple Shifting

Shifting is simplified on the Centauri S. With the Enviolo internal gear hub, just twist the shifter to find your perfect gear. There’s no such thing as a “missed shift” with this step-less system that provides a wide gearing range. Unlike derailleur gears you can shift anytime– while pedaling, coasting or stopped! Just twist and the hub will smoothly transition to the gear you need.

Belts > Chains

Belts > Chains

The Gates belt drive delivers cleanliness and efficiency. With no oil to pick up dirt around town it keeps you neat, and effortlessly sheds mud on backroads. Even better, belts last longer than a chain while being maintenance-free.

Hydraulic Brakes

Hydraulic Brakes

Hydraulic brakes complement the power and durability of the drivetrain. They stop you faster and require less maintenance than cable brake systems.

Hello, Computer
