The Gunai 1000W Ebike is designed for heavy riders, offering a 400 lb weight capacity, reinforced steel frame, and dual suspension. Its 48V 15Ah battery provides 45-60 miles per charge, while the 1000W motor ensures reliable power for steep inclines. Safety features like hydraulic disc brakes and puncture-resistant tires enhance stability for larger riders.
How Does the Gunai 1000W Motor Enhance Performance for Heavy Riders?
The 1000W brushless motor delivers 95 Nm of torque, enabling smooth acceleration and consistent power delivery even under 400 lb loads. It maintains speeds up to 28 mph on inclines up to 30°, outperforming most mid-drive systems. The motor’s thermal management system prevents overheating during extended use, critical for maintaining performance during long rides.
Advanced flux vector control allows the motor to automatically adjust phase currents based on real-time load detection. This technology reduces cogging torque by 40% compared to standard hub motors, ensuring seamless power transfer even when climbing steep hills with heavy cargo. Riders can select between five power modes through the LCD display, with Mode 5 providing 15% extra torque reserve for sudden weight shifts or elevation changes.
| Motor Feature | Standard Ebikes | Gunai 1000W |

| Continuous Power | 750W | 1000W |
| Peak Torque | 65 Nm | 95 Nm |
| Cooling System | Passive | Active Liquid |
What Structural Features Support High Weight Capacities?
Gunai’s triple-reinforced alloy steel frame uses aircraft-grade welding techniques, achieving 2.5x the torsional stiffness of standard ebike frames. The 4.3″ wide tires with Kevlar belts distribute weight evenly across surfaces, while the upgraded 12-gauge spokes prevent wheel warping. The dual crown suspension fork absorbs 80% more impact energy than basic coil systems.
The frame’s hexagonal down tube design increases vertical load capacity by 30% through geometric reinforcement. Critical stress points feature 4mm thick gussets at all joints, tested to withstand over 200,000 fatigue cycles at 400 lbs. The rear rack integrates directly into the main frame structure rather than using bolt-on attachments, supporting 110 lbs of cargo without compromising stability.
“The Gunai 1000W redefines heavy-duty ebike engineering. Its harmonic drive transmission eliminates gear shock common in high-torque situations – a game-changer for riders above 300 lbs. The real innovation is the dynamic load balancer in the motor controller, which adjusts power distribution 100x/second to prevent frame resonance. This isn’t just an ebike – it’s a physics lesson on wheels.”

FAQs
- Can the Gunai 1000W handle off-road trails with a heavy rider?
- Yes, its 160mm travel suspension and multi-surface torque mapping handle technical trails up to 35° inclines at 400 lb loads. The motor automatically increases thermal tolerance by 15% in off-road mode.
- How does weight affect battery life?
- At 400 lbs vs 250 lbs, range decreases by 25% in PAS 5 mode. However, Gunai’s regenerative descent charging recovers 8-12% battery on downhill sections, mitigating this difference.
- What’s the warranty for frame components?
- Gunai offers a lifetime warranty on the main frame and 2 years on mechanical/electrical parts for riders under 400 lbs. High-load users get prioritized support with 3-day component replacement guarantees.
