Unitree B2-W wheel package — the complete four-wheel assembly for the B2-W wheeled quadruped: 4 wheel assemblies and 4 calf bars, one full set for one robot.

The Unitree B2-W wheel package is the four-wheel assembly for Unitree's wheel-legged industrial quadruped — the wheel-feet at the end of each leg that let the B2-W roll across flat ground far faster than any walking gait, while the legs still handle steps and obstacles when the terrain demands it.
The Unitree B2-W wheel package is sold as one complete set: four wheel assemblies and four calf bars, everything needed to refresh all four corners of a single robot. Wheels are the wear items of a wheel-legged platform, so a spare set belongs on the shelf next to the BT2 battery, not on a purchase order after a robot is already grounded.
A fresh Unitree B2-W wheel package brings back the rolling performance the robot shipped with — grip on wet concrete, smooth tracking at speed, and clean transitions between rolling and stepping.
The Unitree B2-W wheel package is the complete four-wheel assembly of the B2-W — the wheel-feet at the end of each leg that make the robot a wheel-legged hybrid. On wheels, the B2-W covers flat ground far faster than any walking gait; on legs, it steps over the obstacles that stop a purely wheeled platform. This package is the rolling half of that equation.
Inside the Unitree B2-W wheel package are four wheel assemblies and four calf bars — one full set for one robot. It is the same assembly the robot ships with, so a fresh set restores the factory ride: the grip, the smooth tracking and the rolling speed the B2-W was delivered with.
The Unitree B2-W wheel package is the four-wheel assembly on its own, for a B2-W you already run. If you are shopping for the complete B2-W robot, this is not that product.
Wheels are the wear items of a wheel-legged robot. Tread that gripped wet concrete on day one goes smooth after enough patrol routes, and a wheel that has clipped a curb or taken a hard landing never rolls quite the same again. Replace the set when tread runs smooth, when a wheel is cracked, deformed or wobbling, or when the robot starts slipping or vibrating on floors it used to take cleanly.
Because the four wheels wear together, the Unitree B2-W wheel package is sold as a complete set of four — refreshing all corners at once keeps rolling behavior matched across the robot. Fleets that run B2-W robots daily typically keep one package on the shelf, so a worn set never grounds a robot while a replacement is in transit.
The Unitree B2-W wheel package fits the B2-W, Unitree's wheel-legged industrial quadruped. Each package is a complete set — four wheel assemblies and four calf bars, one set per robot, so a single order covers the whole machine.

The Unitree B2-W wheel package ships worldwide in manufacturer packaging via DHL or FedEx. The wheel assemblies carry no lithium battery, so no battery shipping restrictions apply — but four wheel assemblies and calf bars make a heavy, high-value parcel, and we pack and book it accordingly.
Every unit is 100% quality-inspected before it ships, so it arrives in perfect working order.
