Powerful Mid-Drive Performance A longitudinal 5kW peak PMSM motor (embedded magnetic cylinder design) delivers up to 117–159 N·m torque at the wheel. You get blistering acceleration (0–31 mph in ~3.6 seconds) and a top speed of 34 mph. Additionally, MTPA/MTPV controllers offer customizable modes (1/2/3 + Reverse) for tailored power delivery and kinetic energy recovery.

Off-Road Capability and Comfort Ride confidently with inverted front suspension (adjustable rebound/compression, 170mm stroke), rear airbag shock (adjustable), and 12-inch front/10-inch rear off-road tires for grip and stability. Furthermore, dual-piston hydraulic brakes (7.09-inch front/6.3-inch rear discs) with tool-free adjustment provide strong, fade-resistant stopping. It handles 25–30° inclines well for its size.

Safe, Smart Battery and Features The 50.4V 25Ah lithium-ion pack with automotive-grade BMS (IP67 waterproof, real-time temp monitoring) offers up to 31 miles range (at ~25 mph; real-world varies by terrain/load). Charging takes 2.5 hours (20–80%) or ~4.5 hours full. Plus, enjoy full-twist throttle, three-stage throttle curve, and durable forged aluminum frame. With its balance of power, lightness, and low maintenance, the Hyper Bee is ideal for off-road excitement—get yours for trail adventures!
