Using your Sunday Darkwave BMX frame is straightforward. First, install the fork (not included) and wheels. The 14mm threaded x 110mm rear axle is standard, so just make sure to tighten the nuts properly. The internal chain tensioners in the hollow dropouts will help keep the wheel in place. When it comes to brakes and gyro, if you need them, attach the removable U - brake hardware and gyro tabs. For daily use, always check the tightness of all bolts and components before each ride. If you notice any rattling or looseness, use a wrench to tighten them up. To maintain your frame, clean it regularly with a mild soap and water. Avoid using abrasive cleaners that could damage the matte black finish. After cleaning, dry it thoroughly to prevent rust. When storing your bike, keep it in a dry place away from extreme temperatures and humidity. If you plan to leave it outside for a short time, cover it with a bike cover. With proper use and maintenance, your Sunday Darkwave BMX frame will serve you well for a long time.
