Performance and Range
Powered by a 3000W brushless rear hub motor with a peak output of 6500W, the HappyRun G300 Pro delivers 120 N·m of torque, enabling speeds up to 50 mph (80 km/h) in off-road mode. The 72V 30Ah lithium-ion battery provides a range of up to 60 miles (96 km) in Class 1 mode (13 mph) and 40–50 miles (64–80 km) in Class 5 off-road mode, depending on terrain, rider weight, and riding style. The battery supports fast charging, reaching 80% in 2.5 hours and a full charge in 5–6 hours with the included 84V 5A charger. The battery is UL 2271 certified for safety, though some sources note it may be underwritten by a Chinese insurance agency rather than a global standard.
Design and Comfort
The G300 Pro features a high-strength aluminum alloy forged frame, offering durability and maneuverability for off-road trails and urban environments. Its 17" high-traction off-road tires ensure excellent grip on rough, loose, or uneven terrain, while the adjustable inverted front fork (80–160mm travel) and vertical rear air-shock absorber (100mm travel) provide superior shock absorption for a smooth ride. The motorcycle-style frame includes functional pedals, blending e-bike versatility with dirt bike performance. The enduro-style saddle is comfortable for off-road riding, though taller riders (over 6’4”) may need adjustments for optimal ergonomics. The bike’s 136.8 lbs (62 kg) weight may feel heavy for some, but its robust build supports up to 330 lbs (150 kg) of payload, making it ideal for carrying gear or delivery loads.
Drivetrain and Braking System
The G300 Pro features a single-speed drivetrain, optimized for simplicity and low maintenance, delivering seamless power transfer for off-road and urban riding. Its hydraulic disc brakes, with 180mm front and 203mm rear rotors, provide strong, reliable stopping power, essential for high-speed rides. Integrated LED lighting, including a 2000-lumen headlight, brake-activated rear light, and turn signals, ensures visibility and safety during low-light conditions. Some reviewers note that the brake rotors could be larger for the bike’s power and weight, requiring careful handling at top speeds.
Smart Features and Connectivity
The G300 Pro is equipped with a mid-mounted color LCD display that provides real-time data on speed, battery life, mileage, and pedal assist levels (0–5). The adjustable throttle curve and multiple riding modes (Class 1–5) allow riders to customize performance for efficiency or power. While the bike lacks Bluetooth or NFC connectivity, its intuitive controls and vibrant display ensure a user-friendly experience. The half-twist throttle offers precise acceleration, making it easy to navigate tight trails or busy streets.
Ideal for Delivery Drivers
For delivery professionals in Toronto, the HappyRun G300 Pro is a powerful and practical choice. Its 60-mile range in lower assist modes supports long shifts with minimal charging, while the 330 lbs (150 kg) payload capacity accommodates heavy delivery loads. The high-traction tires and full suspension system handle urban potholes and light off-road routes, ensuring durability and comfort. The motorcycle-style frame may require some adjustment for frequent mounting and dismounting, but the half-twist throttle provides quick acceleration for time-sensitive deliveries. Street-legal features like turn signals and headlights make it adaptable for urban environments, though riders must check local regulations for compliance, as Class 5 mode (50 mph) is off-road only.
