The Fastron fat tire ebike is equipped with a 4.0-inch ultra-wide tire (with adjustable tire pressure ranging from 5 to 30 PSI), increasing the ground contact area by 120%. Combined with a 190mm hydraulic shock absorber on the front fork (with a rebound damping adjustable at 22 levels), in the passability test on rocky roads, The probability that the wheel height from the ground is less than 3cm has decreased to 7% (31% for ordinary mountain bikes). Data from the 2024 Utah Moab Cross-Country Race shows that its hub motor with a peak torque of 85Nm (power 750W) enables a climbing speed of 12km/h on a 35° steep slope (the industry average is only 8km/h), and the motor temperature rise is controlled within Δ15°C (ambient temperature 40°C).
The suspension system has been verified in extreme environments. The combination of a multi-link rear shock absorber (with a stroke of 200mm) and Kevlar anti-puncture tires successfully absorbed 97% of the vertical impact in the Sahara Desert test (passing through a 10cm deep rut at 30km/h). The BMS intelligently allocates dual battery packs (with a total capacity of 1.8kWh) for output. After two consecutive hours of high-intensity off-road driving, the remaining battery capacity is 42% (generally less than 30% for similar products). In the 2023 Alaska Snow Challenge, the tire hardness only increased by 15% at a low temperature of -25°C (the hardness of ordinary rubber tires increased by more than 50%), and the self-cleaning efficiency of the tread reached 88% (the clogging rate of the tire teeth on muddy sections was less than 5%).
The electronic control security strategy significantly reduces risks. The gyroscope, in coordination with the TCS traction control system (with a response time of 10ms), reduces the probability of skidding to 0.3 times per 100 kilometers (2.1 times for models without TCS), and the hill descent control function (speed lock 3-8km/h) shorts the braking distance on a 45° downhill road by 42%. Long-distance tests in the Gobi Desert of Mongolia have shown that its IP68 waterproof motor (with a water immersion depth of 1 meter per hour) has a zero failure rate in heavy rain, while the nano-coating of the hub bearing reduces the invasion of sand and dust by 76% (the wear after disassembly is less than 0.01mm).
The optimization of battery life and energy efficiency has broken through industry bottlenecks. The dual battery packs support hot-swapping (with a replacement time of less than 15 seconds), and in combination with the energy recovery system (with a braking recovery efficiency of 23%), they achieved a single-charge range of 162km (with a load of 100kg) in the Colorado Mountain trail test. Tests by the “Electric Bicycle” magazine in 2024 showed that its specially designed low rolling resistance tread (Shore A hardness 65) reduced the power consumption for sand riding to 9.2Wh/km (the average of competing products was 12.8Wh/km). The Chilean volcanic expedition team used this vehicle to conquer terrain at an altitude of 6,000 meters, and the low-temperature range attenuation rate was only 18% (the attenuation rate of ordinary ebikes exceeded 40%).
The economy and durability have been commercially verified. It adopts an aviation-grade 6061-T6 aluminum alloy frame (with a fatigue life of over 1 million cycles), and the maintenance cost is 57% lower than that of a carbon fiber frame. A wildlife reserve in South Africa purchased 30 fat tire ebike for patrol. The failure rate within two years was only 3% (the failure rate of traditional off-road motorcycles was 21%), and the operating cost per kilometer was 0.03 (fuel motorcycles required 0.15). At present, 79 professional races worldwide have chosen this car. For instance, the champion driver of the 2024 Norwegian Endurance Race did not replace any parts throughout the race (1,200km), and the frame deformation detection value was less than 0.5mm (safety threshold 2mm).
