The Robot Wheel 70mm x 8mm for BO Motor is a plastic and rubber BO motor wheel measuring 70mm outer diameter and only 8mm width, designed for robot builds requiring large-diameter wheels in tight-clearance chassis or precision line-following applications. This bo motor wheel is the narrowest BO motor wheel in StemVolt’s lineup — at 8mm wide it is significantly narrower than the 15mm bundled BO motor wheels and the 25mm wide individual 65mm BO motor wheel, while maintaining the 70mm diameter for good ground clearance and line travel speed.
The 70mm x 8mm wheel’s ultra-narrow 8mm profile provides two specific advantages over wider BO motor wheels. First, it fits chassis designs with very tight lateral clearance between the wheel edge and the chassis frame or motor bracket where a 15mm or 25mm wheel would not have room to spin freely. Second, the narrow contact patch is beneficial for line follower robot builds — a narrow tyre makes contact with the floor at a more precise point than a wide tyre, reducing the tendency to “drift” sideways on a line course and improving steering response when the robot corrects its path from line sensor input.
The 70mm bo motor wheel’s rubber tyre provides grip despite the narrow profile, and the 70mm diameter produces the same linear travel speed as a standard 70mm wheel at matching RPM. StemVolt provide fast and reliable delivery with trusted service support.
