ONGUARD chain lock for e-scooter ONG-8290 — 4 mm x 90 cm, 2 keys with code

Chain lock ONGUARD ONG-8290 is designed for securing e-scooters and similar personal urban transport. With a 4 mm hardened chain and a 90 cm length, the lock offers flexibility to thread through frame elements and wheels while remaining compact enough for daily carry. The package includes two keyed cylinders supplied with a duplication code, enabling replacement or spare key production when needed. This chain lock is intended for short-term stops and routine urban use where a portable, easy-to-store lock is required.

Advantages

The 4 mm chain construction balances portability and deterrence for opportunistic theft, and the 90 cm reach accommodates most scooter frames and wheel positions. Two keyed barrels with a code allow orderly key management and convenient duplication if a spare is lost. The lock’s compact form factor and moderate weight make it suitable for carrying in a backpack or attaching to a scooter without creating bulk.

Suitable for

• Locking e-scooter frame to fixed objects during short stops
• Securing wheel and frame components in urban environments
• Daily commuting where a lightweight, portable lock is preferred
• Use by riders who want a keyed lock with the option to duplicate keys

Key specifications

• Chain thickness: 4 mm hardened links
• Chain length: 90 cm for flexible locking options
• Locking mechanism: two keyed cylinders supplied with a duplication code
• Recommended use: short-term urban stops and everyday portability

How to use

Thread the chain through the e-scooter frame and, where possible, a wheel or a fixed object such as a rack or post. Insert the keyed cylinder into the locking housing and turn the key to secure the chain; retest the lock engagement before leaving the vehicle. Keep one key with you and store the spare in a safe place or arrange duplication with the supplied code to obtain additional keys if needed. For routine use, coil the chain neatly to reduce wear and to ease carrying.

Usage recommendations

Use the chain lock as a deterrent for brief stops and in combination with a more robust anchor or location choice when leaving the e-scooter unattended for extended periods. Avoid leaving the vehicle in isolated or poorly lit areas; periodically inspect the chain and cylinders for signs of wear or damage and replace if any compromise is detected.
