Holds 70+KW Primary Carbon Belt & Jackshaft CNC Pulley Drive System

Tips: With our hollowed-out design and optimized spacing layout, we estimate that up to 90% of carbon fiber belts on the market can achieve around a 20% increase in lifespan when paired with this drive system.

Upgrade your Light Bee/79Bike Falcon/Ventus/Rerode R1/Eride Pro with REV797’s Primary Drive Belt System—engineered for riders who demand durability, performance, and low maintenance. Replace the stock chain with a quieter, stronger belt system designed for aggressive riding in mud, sand, or city streets.

1. Stronger, Wider Belt: 19mm ( Light Bee/79Bike Falcon/Ventus/Rerode R1/Eride Pro 23T&51T)/25mm (ultra bee 27T&61T) carbon belt offers superior strength and grip compared to the stock 16mm/23mm, designed to withstand high torque, heavy accelerations, and frequent 0–60 tests.

2. Mud-Shedding Pulley Teeth: Hollow, drilled teeth let dirt and sand fall through, reducing wear and extending belt life, perfect for off-road or aggressive trail riding.

3. Quieter Operation, Less Drag, Less Heat: Enjoy the smooth, quiet feel of belt drive with reduced friction and maintenance compared to chains.

4. Signature Whistle Under Load: Hollow teeth produce a subtle “scream” under heavy acceleration—a mark of precision engineering.

5. CNC Machined Mold Steel: Sandblasted, copper- and chrome-plated pulleys for maximum strength, wear resistance, and corrosion protection.

6. Built for Reliability: The pulley fits belts up to 20.5mm (Light Bee, etc) / 25mm (Ultra Bee). Weighing 0.86 lbs, it is heat-treated for toughness and designed to fit stock geometry for straightforward installation.

Upgrade to a drivetrain designed for high-performance, aggressive riders—lighter pulleys, stronger belt, and the ability to evacuate mud and dirt for maximum durability.
