ULAC SOLOIST CX1 ULOCK 100 X 170 MM
ULAC SOLOIST CX1 U-LOCK (100 X 170MM)
The Versatile High-Security Essential.
The ULAC Soloist CX1 is a specialized high-security U-lock designed to meet the needs of modern cyclists, particularly those with wider frame geometries. Featuring a larger 100mm x 170mm internal shackle dimension, it provides the extra clearance necessary to comfortably secure e-bikes, fat bikes, and mountain bikes that often struggle with standard-sized locks.
The lock is built around a 12mm heat-treated hardened steel shackle, striking an excellent balance between formidable cut resistance and manageable weight. It is notably coated in ULAC's signature silicon overmould, which not only provides a comfortable tactile grip but also acts as a protective buffer to ensure the lock never scratches or dings your bike's paintwork.
Key Features
Extended Shackle Dimensions: The 100mm width is specifically tailored for e-bikes and oversized tubes, offering significantly more locking flexibility than traditional narrow U-locks.
Sold Secure Silver Accredited: Independently tested and certified to a Silver level, providing verified resistance against common theft tools in high-risk urban areas.
High-Security Abloy Mechanism: Utilizes a premium disc-detainer cylinder with up to 2,000 unique key combinations, offering superior protection against picking and drilling.
Silicon Overmoulded Craftsmanship: The entire shackle is encased in a seamless silicon sleeve, making it weather-resistant and gentle on your frame.
Optimal Strength-to-Weight: At approximately 970g, it delivers heavy-duty security without the excessive weight of 14mm or 16mm "New York" style locks.
Double-Bolted Design: The shackle locks into the crossbar at both ends, requiring a thief to make two separate cuts to defeat the lock.

✅ Why This IS For You
E-Bike & Cargo Bike Owners: If your bike has a thick down tube or a rear rack integrated into the frame, this wider opening makes locking up much less of a struggle.
Urban Commuters: Perfect for those who need insurance-approved security for daily stops in city centers where theft risk is moderate to high.
Aesthetic-Conscious Cyclists: If you want a high-security lock that looks modern and won't rattle or damage your bike's finish.
❌ Why This May NOT be for you
Extreme High-Risk Areas: While Silver-rated, if you are leaving a very expensive bike in a "theft-magnet" location overnight, you may want to step up to a Sold Secure Gold or Diamond-rated lock.
Ultra-Lightweight Backpackers: If every gram counts, the 970g weight might be noticeable; you might prefer a lightweight alloy lock for quick, low-risk café stops.
Pocket Carry Users: Due to the wider 100mm shackle, this model is less likely to fit in a standard jeans back pocket compared to a "Mini" or "Sport" version.
BFC Pro Tip
The Soloist CX1 is wide enough to capture both your frame and the rear wheel (if passed through the rear triangle) when locking to a standard bike staple. To maximize security, always face the keyway downward; this makes it significantly harder for a thief to attempt to pick the lock or pour corrosive liquids into the cylinder. Since this is an Abloy-style mechanism, a tiny drop of graphite-based lubricant once a year will keep the discs turning smoothly for a lifetime.
