The Texlock Orbit ART2 is a robust bicycle chain lock designed for reliable security during urban commuting and recreational cycling. This high-quality lock features a durable 10 mm hardened steel chain with a protective nylon coating that prevents scratching on bicycle frames while providing weather resistance. The ART2 model incorporates an advanced disc detainer cylinder mechanism with over 10,000 key variations, offering enhanced pick resistance compared to standard pin tumbler locks. With a total length of 90 cm, this lock provides sufficient reach to secure both the bicycle frame and front wheel to various fixed objects such as bicycle racks, poles, or fences. The chain links are individually hardened and tested to withstand cutting attempts with bolt cutters, while the protective sleeve maintains flexibility in temperatures ranging from -20°C to 60°C. Weighing 1.2 kg, the Orbit ART2 balances security with practical portability, featuring a mounting bracket that attaches securely to bicycle frames for convenient transport. The lock mechanism operates smoothly with a key turn of approximately 90 degrees, and the keys are precision-cut with milled edges for consistent operation. This model represents the successor to previous Texlock Orbit designs, incorporating improved cylinder technology and reinforced chain links at connection points. The nylon coating is available in multiple color options to complement various bicycle designs while providing visual identification. For optimal security, the chain should be positioned to minimize ground contact and threaded through both the bicycle frame and wheel when securing to fixed objects. The Texlock Orbit ART2 meets security standards for urban cycling environments and is suitable for daily use with regular bicycles, electric bicycles, and cargo bicycles within city settings.
