Popular shackle length with extra locking options provided by the included 4 foot fully coated, braided steel cable.
Keep your bike secure whilst visiting theft-heavy neighborhoods with the OnGuard Bulldog DT U-lock, which comes with an extra security cable. The Bulldog DT offers a 13mm hardened steel shackle that provides maximum cut resistance, at the side of an X2 double-bolt locking mechanism that locks to two sides of the bar, providing added strength and high pull resistance. The pick-, pull-, and drill-resistant M-Cylinder delivers even more protection, with a BumpBlok mechanism that renders bump keys useless. Very similar to the tumbler systems found on high-end European autos, the M-Cylinder has more than 100,000 conceivable key combinations. These tumblers may not turn unless the secret’s properly inserted, protecting both the key and tumbler from damage because of misuse. The lock mechanism is also completely encased in ultra-hardened steel to withstand drilling, picking, or pulling, whilst an integrated dust cover protects the internals from moisture and debris.
As a bonus, the Bulldog DT includes a heavy-duty, extra-flexible 10mm steel cable, letting you double your protection or lock up another bike on the same rack. Other features include an all-tube, quick-release, multi-position mounting bracket, protective coatings on the cross bar and shackle, and a tough vinyl cable cover. The Bulldog DT comes with five laser-cut keys, one of which has an LED micro-light that will help you open the lock after dark. OnGuard believes so strongly in the Bulldog DT that it offers an anti-theft protection offer of $1,501 for bikes and $501 for power sport vehicles.
