Unlock New Capabilities

• If you've already built micro-robots using the smaller 34mm miniQ wheels or wrestled with the bulky, standard 65mm yellow BO motor wheels, you understand the delicate balance between speed, torque, and ground clearance. Upgrading to a larger wheel size is the easiest mechanical modification you can make to alter your robot's performance profile.
• This 42mm miniQ wheel unlocks higher top speeds and superior obstacle clearance for your N20-powered builds. By increasing the diameter, your robot covers more distance per motor rotation, making these wheels the perfect upgrade for high-speed line followers, larger micro-sumo robots, and miniature exploration rovers that need to navigate uneven terrain without getting high-centered.
• Effort Level: Beginner

Minimum hardware to get started:

• N20 Micro Metal Gear Motor: to physically drive the wheel. The internal D-shaft profile of the wheel hub is custom-molded to fit the 3mm shaft of an N20 motor securely.
• Micro Robot Chassis: to provide a structural base to mount your motors, sensors, and battery.

Included in the Box:

• 1× 3PI miniQ Car Wheel Tyre 42mm for N20 Motor

Frequently Asked Questions

• Is this 42mm wheel compatible with standard yellow BO motors?
  No, the hub is molded specifically for a 3mm D-shaft and will not fit the rectangular cross-shaft of a standard BO motor.
• Can I mount this wheel directly on a TT motor?
  No, TT dual-shaft motors use a flat slotted shaft profile which is incompatible with this wheel's 3mm D-shaped mounting hole.
• Does this wheel fit all variations of N20 micro gear motors?
  Yes, it fits all standard N20, N20 encoder motors, and N30 motors that feature a standard 3mm D-shaft output.
• Can I use this wheel on a round 3mm motor shaft without a D-flat?
  No, it requires a D-shaped shaft to lock in place and prevent slipping under rotational load.
• Does the size of the wheel affect motor power consumption?
  Yes, because of the larger 42mm radius, the motor requires slightly more torque to turn, which can marginally increase current draw under heavy acceleration.
• Will this wheel warp or degrade if exposed to motor heat?
  No, the white central hub is made from durable ABS plastic that easily handles normal operating temperatures produced by N20 motors.
• Is there any electrical isolation provided by this wheel?
  Yes, the ABS plastic hub and thick rubber tire are completely non-conductive, isolating your motor shaft from static or short circuits on the driving surface.
• How do I connect the wheel to the N20 motor shaft securely?
  Line up the flat edge of the motor's D-shaft with the flat side of the internal hub hole and push straight on using steady, even hand pressure.
• Do I need set screws or glue to secure the wheel?
  No, the internal socket uses a precision friction-fit tolerance that firmly holds the motor shaft without screws or adhesives.
• Which direction should the tire tread face during mounting?
  The tread pattern is non-directional, so you can press the wheel on in either orientation without affecting performance.
• Is there specific motor driver code needed for these wheels?
  No, motor driver code controls the motor driver IC (like the L298N or TB6612FNG); the physical wheels react purely to the mechanical torque output.
