Built around Ice Bear's minibike, sport motorcycle platform, the 2025 Ice Bear Menace 50 features a 49.5 cc (3 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. Internal engine geometry specifies a bore and stroke of 38.4 x 41.4 mm (1.5 x 1.6 inches) with a 10.5:1 compression ratio.
On the scales, the Menace 50 measures 136.1 kg (300 lbs) dry. Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,311 mm (51.6 in) wheelbase engineered for quick, flickable steering geometry. The 8.5-liter (2.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
