ONGUARD Rottweiler 8025E e-bike cable lock — 25 mm x 180 cm, 5 coded keys

ONGUARD Rottweiler 8025E e-bike cable lock is a flexible security solution designed for everyday parking and travel. The lock combines a 25 mm diameter protective sleeve with a 180 cm steel cable to secure the frame and wheels of electric bicycles. It is supplied with five coded keys that allow keyed access control and easy sharing between multiple users or as spares. The construction is intended to balance portability with visible deterrence for casual theft during short stops and commuter use.

Advantages

The 25 mm protective sleeve increases resistance to cutting tools compared with thin cables while reducing the risk of paint damage to the bicycle frame. A 180 cm length gives flexible anchoring options, enabling attachment to posts, racks and fixed objects at a variety of angles. Inclusion of five coded keys eliminates the need to carry duplicates or rely on a single key; the keyed system provides straightforward operation without combinations or electronic batteries.

Suitable for

• Short-term parking of e-bikes and bicycles in urban environments
• Commuters who need a portable, flexible locking option
• Securing both frame and wheels to a fixed object
• Shared use where multiple keyed copies are required

When it may not be suitable

This cable lock is not intended as the sole security measure for high-risk locations or prolonged unattended storage where determined thieves may use heavy cutting tools. For long-term parking in high-crime areas or for securing high-value e-bikes overnight, a hardened U-lock or chain lock rated for heavy-duty security should be considered in addition to or instead of a cable lock.

Key specifications

• Cable diameter: 25 mm protected sleeve
• Cable length: 180 cm (flexible steel core with protective covering)
• Lock type: keyed cylinder mechanism
• Keys supplied: five coded physical keys
• Intended use: frame and wheel securing for e-bikes and bicycles

How to use

Loop the cable through the bicycle frame and one or both wheels, then pass the cable around a fixed object such as a bike rack or a pole. Insert the cable end into the keyed locking cylinder and turn the provided coded key to lock. Keep at least one spare key in a secure place. When unlocking, insert the matching coded key, turn the cylinder and withdraw the cable. Store the lock in a pannier, backpack or attached to the frame while riding to maintain portability.

What to consider before purchase

• Level of theft risk at typical parking locations (short-term vs long-term security needs)
• Need for portability and cable length for your common anchoring points
• Preference for keyed access and the requirement for multiple keys
• Compatibility of cable diameter and length with your bike frame and rack layout

Usage recommendations

For improved security, use the ONGUARD Rottweiler 8025E together with a secondary rigid lock (U-lock or hardened chain) to protect the frame and critical components. Always lock through the frame and at least one wheel, choose well-lit and visible parking spots, and retain spare keys in a separate secure location.
