Unlock New Capabilities

• If you've already experimented with standard 65mm yellow BO motor wheels or built basic, bulky robot chassis, you already understand robot kinematics — which means you're perfectly ready to downsize your builds for higher speed and precision.
• This 34mm miniQ wheel unlocks ultra-compact robotics, allowing you to build micro-sumo robots, high-speed line followers, and precise desktop maze-solving bots. These are builds that require a low center of gravity and a tight turning radius, which you simply cannot achieve reliably with standard-sized wheels.
• Effort Level: Beginner

Minimum hardware to get started:

• N20 Micro Metal Gear Motor: to drive the wheel, as the internal D-shaft profile of the wheel hub is specifically molded for the 3mm shaft of an N20 motor.
• Micro Robot Chassis: to mount your motors and provide a structural base for your compact robot build.

Included in the Box:

• 1× 3PI miniQ Car Wheel Tyre 34mm for N20 Motor

Frequently Asked Questions

• Is this wheel compatible with standard yellow BO motors?
  No, the hub is specifically molded for a 3mm D-shaft and will not fit the flat double-sided shaft of a BO motor.
• Can I use this 34mm wheel on a TT motor?
  No, TT motors have a different shaft profile; this is designed exclusively for N20 and N30 micro metal gear motors.
• Will this fit a standard 3mm round shaft motor?
  No, the mounting hole is D-shaped to prevent slipping, and it will not fit securely on a perfectly round 3mm shaft.
• Is this wheel suitable for both 2WD and 4WD chassis builds?
  Yes, they work perfectly in both configurations for micro-sized robotic platforms.
• What is the maximum weight capacity of this wheel?
  A pair of these wheels can comfortably support micro-robots weighing up to 500 grams without compressing the tire excessively.
• Does the 34mm wheel size affect the speed of the N20 motor?
  Yes, a 34mm wheel offers a great balance, providing higher top speed than smaller 20mm wheels while maintaining better torque than larger 43mm variants.
• Can these wheels handle high-RPM N20 motors (e.g., 1000 RPM)?
  Yes, the tight D-shaft fit prevents the hub from slipping even at high speeds or under sudden acceleration.
• How do I install this wheel onto the N20 motor?
  Carefully align the flat edge of the motor's D-shaft with the flat edge inside the wheel hub, then press firmly straight down.
• Do I need screws or glue to secure the wheel?
  No, it utilizes a precision friction-fit design that holds securely without additional hardware or adhesives.
• Can the rubber tire be removed from the plastic hub?
  Yes, the rubber tire can be gently stretched and removed for cleaning or if you need to paint the plastic hub.
