Revi Bikes Flux 750W: The Ultimate Heavy-Duty Electric Cargo Bike

Massive Payload Capacity Meets Smart Utility Engineering

The Revi Bikes Flux is designed to be the ultimate workhorse for your daily life. Whether you are transporting gear, groceries, or passengers, the 750W high-torque motor (peaking at 1200W) provides the muscle needed to move up to 440 lbs of total payload. With 85 Nm of torque, this bike maintains consistent speed up steep hills even when fully loaded, making it the perfect replacement for your car on local errands.

Built for Safety and Versatility

Utility doesn't come at the expense of safety. The Flux features a low 14" step-through frame, making it incredibly easy to mount and dismount while the bike is loaded. It is equipped with integrated rear lights featuring turn signals and brake lights, ensuring you are visible and your intentions are clear to traffic. To handle the extra weight, the Flux comes standard with 180mm hydraulic disc brakes and a front suspension fork to keep every ride stable and controllable.

Expandable Power & Storage

• Dual Battery Ready: Start with the 48V 15Ah Samsung battery for a 55-mile range, or utilize the reserved space to add a second battery for double the distance.

• Integrated Utility: The heavy-duty rear rack supports up to 180 lbs, while the included free front rack helps distribute weight evenly. When not using a second battery, the reserved space converts into a waterproof storage bag for tools and snacks.

• Passenger Ready: Safety is built-in for your smallest passengers with included rear wheel guards and footboards, protecting feet from moving parts.

• Ergonomic Cockpit: Find your perfect riding position with the adjustable stem, designed to reduce strain on your wrists and neck during long hauls.

Frequently Asked Questions

How does the dual battery system work?

The Flux is designed with a reserved compartment for a second battery. You can choose to add a 10Ah or 15Ah pack to effectively double your range. The system is engineered so that a single charger can replenish both batteries simultaneously through the bike, eliminating the need for multiple cords.

Is the step-through frame strong enough for a 440 lb load?

Absolutely. The frame is constructed from reinforced 6061 aluminum alloy specifically engineered for cargo stress. The 14-inch standover height provides a lower center of gravity, which actually makes the bike more stable and easier to balance when you are carrying heavy groceries or passengers.

Can I carry children on the rear rack?

Yes, the Flux is passenger-ready. The integrated rear rack is rated for 180 lbs and the bike comes equipped with rear wheel guards and passenger footboards. These safety features are designed to keep your passengers' feet secure and away from the spokes during travel.

What is the difference between the Class 2 and Class 3 modes?

Using the LCD display, you can choose between Class 2 mode, which allows for throttle-activated riding up to 20 MPH, or Class 3 mode, which deactivates the throttle but provides pedal-assist power up to 25 MPH. This allows you to stay compliant with different local trail and road regulations.

How do the turn signals operate?

The turn signals are integrated into the rear lighting system and are controlled by a switch on the handlebars. When activated, the appropriate side blinks to signal your turn to vehicles and pedestrians behind you, providing a higher level of safety than standard hand signals alone.
