Using your Kink Launch BMX bike is easy. Just hop on, hold the Kink T875 8.75” bars firmly, and start pedaling. This bike is great for riders around 5’3’’ – 5’7’’, so make sure it's the right size for you. When riding, always wear proper safety gear like a helmet. As for maintenance, since it has a sealed integrated headset and a sealed Mid bottom bracket, you won't have to worry too much about these parts. But it's a good idea to check the tires regularly for proper inflation and any signs of wear. Also, keep the chain clean and lubricated for smooth pedaling. If you notice any unusual noises or problems, take it to a professional bike mechanic for a check - up.
