Centauri S Key Highlights

Clean lines

We know it's an ebike, but we didn't need it to scream "I AM AN EBIKE." Our bikes take aesthetic cues from vintage cruisers and classic rides.

Hop on with ease

Getting on and off your bike has never been easier! A lower top tube makes stepping onto your bike simple and safe.

Smooth shifting

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!

reviewers love Centauri S:

The Centauri is easy to ride and maintain

With its sporty geometry and advanced drivetrain, the Centauri is easy to ride and maintain by design.

-Cycle Volta

Vvolt has set the bar for power and versatility at a reasonable price

I found I prefer this pedal assist over a throttle...the motor is strong and completely silent, and responds to input seamlessly and proportionally.

-Mountain Weekly News

find your perfect fit

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 motor is plenty efficient for you!

  • Stellar Series models come in two sizes that should comfortably fit most people. You'll still want to choose the one that’s best for you!
  • Utility Family models all have a lower stepover and fit most riders between 4'9" and 6'4"

We recommend you compare your inseam measurement, taken wearing shoes you are likely to ride in, to the stand-over height of our various models. As long as you've got around 1" of clearance over the top tube you'll likely be good to go! If you're on the cusp between sizes we generally recommend sizing up. Don't hesitate to reach out if you've got any sizing questions!

Components & Specs

Enviolo hub

Way better than derailleur gearing. The Enviolo TK continuously variable transmission hub features 380% range and never needs adjustment.

MPF 6C motor

We're fans of the strong and silent type, so we use an MPF mid-drive motor with all-metal gearing in an oil lube bath. It has 350-watt nominal power and 650-watt peak output.

* Mid-motor battery

375 Wh standard battery provides 15-40 miles of range depending on terrain, assist level, and other factors - an upgraded 500 Wh battery is available. All of our batteries are removable and can be charged on or off the bike.

* Class 1 or 3 controller

Our mid motor bikes can be configured with a Class 1 or Class 3 controller.

Our Class 1 controller will provide motor assistance up to 20 mph, while our Class 3 controller will provide motor assistance up to 26 mph. That's fast!

Mid motor display

Our mid motor handlebar display has 6 levels of assist plus walk mode, a backlight and USB power-out. In assist mode 0 your Vvolt can be ridden without motor power, just like an analog bike. In assist mode 5, you're getting maximum power. Full speed ahead!

Hydraulic brakes paired with 160mm rotors provide ample stopping power

Centauri tires

27.5'' x 45mm tire with smooth tread for fast-rolling on pavement. Wide enough to tame bumps and offer increased tracking on gravel or hard-packed dirt

Gates belt

Carbon reinforced belts from Gates® last longer than chains, operate quietly, and don't require grease -- no more unintentional chainring tattoos!

What are ebike class designations and what are your ebikes?

In the USA There are currently 3 class designations for eBikes: Class I, Class II, and Class III.​In most states, ebikes are regulated according to this 3-class system.

  • Class I ebikes provide motor assistance up to 20 mph while the rider is pedaling. This is referred to as pedal assist, sometimes abbreviated as PAS.
  • Class II eBikes similarly provide motor assistance up to 20mph but also are equipped with a throttle. Riders can choose to use either the pedal assist or the throttle.
  • Class III ebikes provide pedal assistance up to 28 mph. Some Class III eBikes are also equipped with a throttle, but the throttle use will only assist the rider up to 20mph.

Our hub motor bikes (Alpha and Alpha S) are both Class I, whereas our mid-drive bikes (Centauri, Proxima, Sirius) can be equipped with either a Class I or Class III controller.

It’s important to understand the rules and regulations in your state or municipality to ensure you’re operating the bike in a safe, legal manner. See this guide from People for Bikes for more detail

What's the difference between hub motor and mid motor bikes?

The primary difference between the two motor systems is how and when each motor system provides assistance.

Our hub motor bikes (Alpha and Alpha S) use a wired bottom bracket with a cadence sensor. When you begin pedaling, the controller senses the pedals rotating and provides assistance based on the level selected by your handlebar display. This system is simple, tried, and true, though it can sometimes feel a little like you're being pushed from behind.

Our mid-drive bikes (Centauri, Proxima, Sirius) also use a torque sensor to engage the motor. This system is a bit more complex: both torque and cadence sensors work to measure your input and provide natural-feeling assistance. The harder you pedal, the more assistance will be provided by the motor! Our mid-drive motors have twice the torque and a higher wattage than our hub motor bikes.

Hub motors are great for riders on a budget or those looking to ride with less strenuous effort. Mid-drive motors are great for riders looking for a natural pedal feel that more closely matches an acoustic (non-e)bike.

Can I put cool accessories on my ebike? What if I want to change some of the components as well?

Racks, fenders, and mirrors, oh my! We configure our ebikes with standardized component sizes and mounting locations so you can customize your ride as you see fit.

All of our ebikes can accommodate front and rear racks, fenders, different tires, handlebars, grips, stems, seat posts, saddles – you name it!

If you have a particular part you’re interested in fitting on your VVolt ebike, please reach out to us! We’re interested in helping you feel good on your bike and will do what we can to ensure your comfort, safety, and satisfaction.

What type of terrain suits this bike?

This Vvolt ebike falls under ASTM level 2 conditions. Operation should be limited to regular paved surfaces as well as unpaved and gravel roads and trails with moderate grades. Contact with irregular terrain and loss of tire contact with the ground may occur. Drops are intended to be limited to 6 inches or less. Riding outside of these conditions incurs risk and may damage the bike or result in serious injury.
