Difference Between ZF, BF1, BF3 & Electric Power ZF: With the ZF system, you must move the shift lever to switch between forward and reverse. The reverse gear is actively engaged. BF1: With the Brake Freewheel (BF1), you do not need to shift. You can drive forward and reverse simply by pedaling in the desired direction. At the same time, the integrated back-pedal brake allows you to stop gently and safely. BF3: The Brake Freewheel with 3-speed gear system allows forward and reverse driving without manual switching. The integrated back-pedal brake ensures particularly safe and comfortable braking. The 3 gears provide the right transmission for any terrain. Electric Power: The Electric Power system supports you with an electric motor while pedaling. You can adjust the assistance level to match your needs. A practical start assist makes pulling away easier, even on inclines. Safety and Warning Instructions: Are you ready for your next go-kart race? Your challenge starts soon! Get your DINO CARS SUPER SPORT out of the garage, check your kart, make sure the tire pressure is optimal, and adjust the chain tension. Then it’s time to hit the track! The SUPER SPORT is the kart where safety and comfort are at the forefront. The sturdy steel tube frame and air tires with ball-bearing smooth-running wheels are the constants for an exciting driving experience. The 6-position seat adjustment makes the racing go-kart compatible for children and adults from 5 to 99 years old. The front pendulum axle – with extra-large travel – ensures that all four wheels stay on the ground, even on uneven tracks. Another highlight is the extra-thick powder coating of the vehicle frame, which also tolerates minor accidents. The DINO CARS SUPER SPORT features a robust ball-joint steering system, allowing you to cruise easily through every corner. The chain is adjusted using the easy-to-use chain tensioner, making it simple and convenient. The fully enclosed chain guard prevents injury risks and keeps the chain free from dirt. Additionally, welded steel reinforcements in the seat mountings prevent seat wobble. This is DINO CARS quality that pays off when reselling. As you can see, safety and comfort are uncompromised with the DINO CARS SUPER SPORT. assembly Instructions Download assembly instructions Technical Explanation of ZF Hub The product shown in the image may differ from the original.
