Alpha S Key Highlights

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.

Simplicity exemplified

With one speed and no shifting system, controlling your Alpha is as easy as selecting your level of motor assistance to adjust how hard you have to pedal. The perfect bike for relatively flat commutes and casual cruising.

Quiet, hassle-free belt

No messy clunky chains here: get ready for a whisper quiet ride. The drive belt lasts 2-4 times as long as chains and provides consistent power, unlike traditional bike chains that lose efficiency as they get dirty and worn. Moreover, wear your white pants after labor day and avoid grease marks!

Finally, An E-Bike That Looks Cool

The VVolt Alpha S is the perfect bike for someone who wants a simple, no-frills commuter bike with the extra assistance a motor can offer. Want to get to work a little faster or less sweaty but still in style? This is a great e-bike for you.

The Alpha S features a quiet, smooth, efficient, and maintenance-free ride


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!

What if I want a larger battery on my Alpha?

Ah, so sorry :^( Our Alpha and Alpha S models are only available with a 375wh (10.4ah) battery at this time.

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.
