Revi Bikes · Flux Cargo E-Bike
The Revi Flux is a longtail electric cargo bike built for real family life: a 440 lb payload, a 180 lb rear deck that takes child seats and passengers, a free front rack, and a 750W motor with 85 Nm of torque that flattens hills with everything loaded. Add the second battery and ride up to 120 miles.
| Pick your setup | Single Battery — $1,599 | Dual Battery — $1,699 |
|---|---|---|
| Battery | 48V 15Ah (720Wh) Samsung cells | 15Ah + 10Ah (1,200Wh total) |
| Range | Up to 55 miles | Up to 120 miles (PAS 1, Eco) |
| Second-battery bay | Doubles as a storage bag for tools & snacks | Holds the second battery |
| Charging | 4–6 hrs | One charger fills both batteries at once |

More Power for More Cargo
Cargo bikes live and die on torque. The Flux's 48V 750W motor peaks at 1,200W with 85 Nm — enough to boost up steep hills and hold speed with heavy loads, up to 28 MPH.
Five pedal-assist levels plus a throttle, with Class 2/3 selectable right on the full-color display.

Dual Battery Option
The removable 48V 15Ah Samsung-cell battery runs up to 55 miles. Add the second battery (10Ah or 15Ah) and stretch it to 120 miles — school runs, grocery trips and delivery routes on one charge.
One charger fills both batteries at the same time. Skip the second battery and its bay becomes a built-in storage bag for tools, snacks and water bottles.

Built for Precious Cargo
The longtail rack carries 180 lbs and accepts most child seats on the market. Rear wheel guards and bamboo footboards come standard, keeping little feet and loose straps away from the wheel.
The 14" step-thru standover — lower than nearly every competitor — means you can hop on and off with a full load without swinging a leg over.

Seen and Safe
The integrated rear light adds turn signals and an automatic brake light — tap the signal on the bars and the correct side blinks, just like a car. Anti-puncture 20"×2.4" tires carry reflective sidewall strips for extra night visibility.
Hydraulic disc brakes on 180mm rotors and a front suspension fork keep the whole load composed.
Sold separately in our accessories shop — turn the deck into whatever the day needs.
