Engineered by Ice Bear for the scooter motorcycle segment, the 2023 Ice Bear Maddog 150 features a 150 cc (9.2 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 1.9 HP (1.4 kW) at 5,500 rpm while maximum torque reaches 2 Nm (1.5 lb-ft) at 4,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 12.7 HP per liter and a 1,000 rpm working window between peak torque (4,500 rpm) and peak power (5,500 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Maddog 150 measures 158.8 kg (350 lbs) dry. Rider ergonomics and chassis geometry center around a 599 mm (23.6 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,598 mm (62.9 in) wheelbase engineered for planted straight-line stability. The 6.06-liter (1.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
