The Single-Drum Roller is a charming and classic construction vehicle. This set perfectly captures the essence of a road roller with its vibrant yellow color scheme and functional design, making it a standout piece in any LEGO City layout.

This set is perfect for young builders and LEGO City enthusiasts. With a manageable piece count and straightforward building techniques, it offers a satisfying build experience that can be completed in an afternoon, and the included minifigures add to the playability.

📈 Investment Analysis

C+
Investment Grade
⏳ Appreciating
The 7746 Single-Drum Roller presents a modest investment opportunity. While the set is retired and its price is trending upward, its piece count and theme may limit significant appreciation. The set's appeal to LEGO City collectors and its relative rarity contribute positively to its investment potential. However, the absence of highly sought-after exclusive elements or minifigures suggests it may not reach the same heights as other retired sets.

📖 About This Set

LEGO® City is always growing, and right now it needs new roads! With its massive drum, the construction roller flattens soil and asphalt to make safe roads for city vehicles to drive wherever they need to go. Roller drum spins to flatten the soil and the front end pivots with every curve of the road! Includes 2 construction worker minifigures and accessories Measures 7" (17cm) long

Compare Similar Sets

Compared to other LEGO City construction vehicles, the Single-Drum Roller offers a simpler and more compact design. While sets like the larger excavator or crane provide more complex builds and functions, this set is more accessible for younger builders and fits well within a smaller LEGO City display. Its focus on a specific type of construction vehicle also makes it a unique addition to a collection.

2 Minifigures Included

The set includes two identical construction worker minifigures, distinguished only by one having sunglasses. They are fairly standard LEGO City figures, but add playability to the set.
