Adding bigger tires and bump-taming front suspension to a powerful mid-drive motor and reliable internal gear hub, the Sirius takes our hassle-free philosophy to the trails!
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.
We plan for Alpha orders to begin shipping August 15 (Proxima/Sirius Sept 15)
Standard FedEx ground shipping is free within the contiguous US and your bike will arrive within 5 business days of shipping. If you are in AK or HI please reach out to our support team for ordering options.
Check out our super easy assembly instructions before your bike arrives - we honestly think anyone can do it in around 20 minutes!
If you'd feel more comfortable having a professional mechanic assemble and prep your bike, you can check your shipping options in checkout to see if your location qualifies for $100 shipping and assembly at a shop near you!
Vvolt electric bicycles include a standard three year warranty against manufacturer’s defect, with no mileage limitations. Our warranty covers issues you may have with your bike, inclusive of battery, motor, transmission, belt, wheels, brakes and other components.

Reliability is key when you’re venturing beyond where other vehicles can take you. With plenty of torque and an internal transmission protected from the hazards of the trail, the Sirius is ready to search out new places or help you reach your favorite destinations with greater ease.
27.5” wheels offer a more nimble ride than 29” wheels, key when managing the extra mass of an ebike on singletrack.
The suspension fork offers 100mm of travel, suitable for all sorts of unpaved paths, cross-country trails, and those bumpy roads around town.
Our standard 375wh battery provides up to 60 miles of range, more than enough for the average daily ride. Our integrated batteries maintain a clean look and reserve space in the frame for water bottles and other accessories. Our integrated batteries can be charged in place, or removed and carried by themselves if your bike storage location doesn't have electricity.
