LEGO Ninjago set 71734, Kai's Blade Cycle, is a 2021 model based on Kai’s vehicle in the Ninjago theme. It contains 54 pieces and includes 2 minifigures, Kai (Legacy) and Serpentine Rattla - Sand Blue.

Kai's Blade Cycle belongs to the Ninjago theme and depicts a vehicle associated with Kai.

The build focuses on a small, action oriented motorcycle made from 54 pieces. The model is therefore easy to understand as a vehicle based duel rather than a display of scenery.

This set suits Ninjago minifigure collectors, fans of small vehicles and builders looking for a simple addition to the theme. On display, it works as a Kai focused scene. For play, its compact format supports quick chases, confrontations and integration with other Ninjago models.
