Caofen is the first enduro electric dirt bike that introduced a solution for durability of its battery. As you are aware, the battery of the dirt bike is the one subjected to the highest abuse because of the high-power demand. This generates heat which is the slow killer of the Lithium batteries. Caofen implemented high discharge rate batteries, but also submerged them in dielectric fluid that constantly cools them. Another advantage are two safety features usually available for high end motorcycles. There is an electronic ABS brake system that can be engaged and disengaged by a switch. The same applies for the regenerative braking system. And that’s not all. With its 72V/48AH battery this bike is capable to a range of up to 200km.
Q: Why Caofen F80L is better than Surron LBx?
A: Bigger battery, more powerful motor, motorcycle grade front, rear suspension and brakes plus ABS, while sur-ron uses bicycle parts.
The Caofen F80B Off-Road e-bike is an exceptional off-road bike that is built to withstand the test of time. Boasting an AlMg alloy frame construction, a high charge and discharge rate battery, and an 8KW motor, this bike is engineered to conquer the toughest terrains and climates. Caofen F80B sets itself apart by offering a remarkable 2-year bumper-to-bumper warranty, a rarity in the world of dirt bikes, considering the harsh conditions they are typically subjected to.
FRAME
The Caofen F80B features a meticulously designed frame that follows the monocoque principle, completely eliminating welding. All components are securely enclosed within its lightweight magnesium-aluminum alloy construction.
With a weight of only 5kg, this frame utilizes an alloy that is 33% lighter than aluminum and 25% stronger than aluminum. One of the greatest advantages of magnesium alloys is their remarkable fatigue strength, enabling them to endure repeated stress without compromising integrity. This makes magnesium alloys an optimal choice for building structures exposed to frequent stress.
BATTERY
The Caofen F80B features 72V/32AH battery with total capacity of 2.3KWH. The longevity of lithium-ion batteries greatly depends on the management of excessive heat. The Caofen F80B distinguishes itself as the first electric dirt bike to feature a patented immersion cooling battery system. This innovative design equalizes the temperature of the battery cells, efficiently distributing it to the magnesium-aluminum shell which dissipates the heat. As a result, overheating at critical points is prevented, and the inclusion of fire retardant liquid within virtually eliminates any risk of fire or explosion. The thermal balance ensures a temperature rise that is only 50% of the normal level.
This advanced cooling and heat distribution system enables riders to tackle extreme temperature variations, ranging from -20 to +40 degrees Celsius. Additionally, this battery can be charged regularly using a fast charger without compromising its lifespan, with a charging time of only 2 hours from a 15-amp socket.
ELECTRONIC CONTROL
The Caofen F80B is equipped with a sophisticated control system that empowers riders to enable or disable a variety of functions. The bike features three settings, allowing users to maximize torque, speed, or range based on their preferences. Furthermore, an efficient regenerative brake system can extend range by 12%, though it can be disabled at any time. The display shows Current speed, Total mileage, Error codes, Real time output current, Battery State of Charge, trip distance and remaining distance.
Brake kill switches can also be independently disabled, granting riders the freedom to utilize each wheel’s brakes without affecting the motor. As an additional security measure, an electronic actuator system locks the handlebar when the bike is not in use.
MOTOR AND TRANSMISSION
The Caofen F80B motor is designed with an axial flux winding that delivers impressive torque without the need for preliminary gear reduction. This design simplifies the transmission system while increasing overall efficiency. The gear ratio of both the front and rear sprockets enables a top speed of 85 km/h, but 13-tooth sprockets are also available to enhance torque by 15%.
Overall, the Caofen F80B Off-Road e-bike excels in durability, performance, and cutting-edge features. Its AlMg alloy frame, innovative battery cooling system, customizable electronic controls, and efficient motor and transmission make it an exceptional choice for riders seeking a reliable and thrilling off-road experience.
