Types of towbars for Škoda Superb 2: which one to choose?

There are three main types of towing devices on the market for Superb 2, differing in design and method of fastening:

• 🔧 Fixed tow bar — rigidly welded or bolted structure without the possibility of removal. Suitable for regular use, but may interfere with parking sensors.
• 🔄 Removable tow bar — the ball is removed using a lock or lever. Optimal for those who rarely use trailer hitches. On Superb 2 requires additional modification of the bumper.
• 🔗 Flange tow bar - universal version with bolt-on mounting. Allows you to adjust the height of the ball, but is less reliable under heavy loads.

For Škoda Superb 2 the most popular models are from Bosal, Westfalia and Thule. For example, Westfalia AH25B (article 3135250020) - removable towbar with vertical load up to 100 kg, which does not require trimming the bumper. But Bosal K-189 (089-514) - fixed version with a load capacity of up to 2000 kg, but may conflict with parking sensors.

When choosing, pay attention to:

• ⚖️ Maximum vertical load (for bicycle racks it is this that is critical, and not the overall load capacity).
• 🔌 Socket type: 7 pin (12V) or 13-pin (12V + 24V for trailers with brakes).
• 🛠️ Need to improve the bumper. On Superb 2 with parking sensors, the installation of special spacers is often required.
