If you want to shoot some fast-paced mountain bike action, the GoPro Hero8 Black is the ideal choice. This is due to the fact that it captures 4K super HD footage at 60 frames per second using HyperSmooth 2.0. So, if you want smooth footage that can be slowed without sacrificing quality, the Hero8 is your best choice. It has a wide range of sensitivity from ISO 100-12800 (expandable to 25600) for low light filming. Furthermore, it has built-in Wi-Fi and Bluetooth technology, so you don't need an additional device to control it. Also, it has an automatic power-off function when removed from its mount, which saves battery life. Finally, it is waterproof up to 40 meters (130 feet), making it perfect for capturing underwater shots too! The only downside to this camera is its price tag. At $500, it isn't exactly cheap, but if you're looking to capture high-quality videos at any time then it's worth the investment. Also, note that there are other GoPros with similar features but at different prices; therefore, you may want to do some research before buying.
