Centauri 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.

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!

Removable battery

The battery pops out with the simple twist of a key so you can easily charge separately from where your bike is stored.

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! Each model comes in two sizes that should comfortably fit most people. You'll still want to choose the one that’s best for you!

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!

Brakes

Hydraulic brakes paired with 160mm rotors provide ample stopping power

Gates belt

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

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

FAQs

Can I put a larger battery on this ebike?

You betcha! Our mid-motor bikes can be equipped with a 500wh battery, a 30% increase over the standard 375wh battery.

Does this ebike come equipped with a throttle?

No, none of our first generation bikes are equipped with a throttle. We decided to forego using throttles on our bikes due to range concerns: our 375wh / 10.4 amp hour batteries work great for assisting pedaling effort though do not have enough capacity to support throttle use.

We plan on offering a throttle on future models with larger batteries and different riding use cases (cargo & utility bikes).

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.
