Electrifier 100RPM Dual Shaft BO Motor with 65mm Wheel, 2WD Set of 2 | Drives 2WD chassis with caster support, 0.8 kg cm torque, 3V start, encoder-ready rear shaft, low current battery drive

Most beginner and classroom robots are two wheel drive: a pair of powered wheels at the back, a free-rolling caster in front, and steering handled entirely by varying the speed of each motor. This Electrifier pack supplies exactly that pair — two geared BO motors with two 65mm rubber-tread wheels — so you buy the drive stage in the quantity the architecture actually calls for, with nothing left over in the parts bin. Both motors share the same 100RPM gearing and 0.8 kg cm torque rating, giving the left and right sides a common baseline that your motor driver refines through PWM control for straight tracking and smooth turns. The 3V to 12V operating window with a 40 to 180mA no-load draw means the pair runs from AA battery holders and 9V packs just as readily as from a regulated bench supply, and it sits comfortably within the current limits of L298N and L293D driver boards. The dual shaft design leaves the rear stub of each motor exposed, so an encoder disc can be added the moment your project moves from open-loop driving to measured speed and distance. Wheels press onto the D-profile shaft by hand — no screws, no adapters — and the textured tread grips tiles, wooden desks, and lab flooring. Beyond fresh builds, the two-piece format earns its place as a repair and upgrade pack: swap out a strained motor on a line follower, motorise a static science model, or keep a spare axle set ready during workshop season. Part of the Electrifier robotics components line, covered by a one-year warranty and produced under ISO-certified manufacturing, with every specification cross-checked before listing.
