The terrain test of the TUV Rheinland laboratory in Germany shows that when the pressure of the 4.8-inch wide tire drops to 5psi on the sandy tire, the rolling resistance coefficient is only 0.008, which is 62% lower than that of the 2.35-inch narrow tire. The measured traction coefficient in the Norwegian ice and snow environment reached 0.61 (0.35 for narrow tires), and the adult fat tire electric bike equipped with a motor with a torque of ≥85N·m achieved a 25° snow slope climb (the limit of 18° for narrow tires). The National Park Service of the United States reported that the accident rate of wide-tire vehicles on unpaved roads is 34% lower, and the capacity retention rate of IPX7 batteries in an environment of -20℃ is 92%, which is 58% higher than that of ordinary models. This combination of technologies has increased the daily delivery efficiency of Alaska postmen by 40%, with a daily mileage of 75 kilometers (only 48 kilometers for standard vehicles).
The full life cycle economy has significant advantages. The five-year usage model reveals that although the initial cost is 68% higher (average price 1,500vs890), the maintenance cost is saved by 37%. The key data include: the annual tire replacement cost is 180 (105 for narrow tires), but the self-rehydration technology reduces the frequency of puncture repairs to 0.3 times per year (0.9 times for narrow tires), the annual maintenance of belt drive is 18 (48 for chains), and the maintenance cost of the shock absorption system is 50 per 8,000 kilometers. More importantly, there is the energy economy – Rotterdam users have proven that they can replace car commuting with fuel costs, saving 1,200 yuan and 600 yuan in parking fees annually. Coupled with the EU energy subsidy (€210 per year), the premium recovery period has been shortened to 14 months. The London case further shows that the residual value rate of wide-tire vehicles reached 41% after five years (36% for narrow-tire vehicles).
The safety protection performance has achieved a breakthrough across generations. The four-piston hydraulic disc brake system reduces the probability of skidding accidents by 52% at a wet braking distance of 2.1 meters (3.4 meters for narrow-tire vehicles). The Finnish Safety Certification Center has confirmed that the built-in gyroscope self-balancing system reduces the ice surface rolman rate to 4% (37% for ordinary vehicles), and the structurally reinforced frame (with a wall thickness of 3.5mm) has a peak load capacity of 250kg, with an overload deformation rate of less than 0.05mm/km. The upgraded lighting system brings night-time safety guarantees – the 2,000-lumen headlights have a illumination distance of 120 meters, and the 240° warning taillights reduce the traffic accident rate by 61%. German users have reported that as a result, 89% of night-time collision risks have been avoided.
The application scenarios have been expanded to break through traditional limitations. The measured data from the California coast shows that on a beach with an 8° slope, the speed can reach 28 kilometers per hour, which is 175% faster than mountain bikes. During winter mixed terrain commuting (with snow and paved roads), the average speed remained stable at 20 kilometers per hour, which was 67% higher than that of traditional vehicles. The load capacity is more innovative in freight standards: when the triangular shelf can bear a load of 100kg, the body deflection Angle is less than 1.5°. The Amazon logistics vehicle has been measured to transport 36 bottles of drinking water in a single time (18 bottles for a standard vehicle). Data from Nordic users show that the median annual usage frequency of wide-tire vehicles is 142 times (95 times for standard vehicles), and the travel rate during heavy rain is as high as 91% (only 42% for standard vehicles).
The environmental value needs to be examined in a balanced way. The annual carbon reduction reaches 1.2 tons (equivalent to the carbon sequestration of 54 trees), and the urban traffic noise is 58dB (65dB for standard vehicles). However, the material sustainability report reveals that each wide tire emits 380g of rubber particles per year (210g for narrow tires), and the industry is improving through 35% recycled tire material technology. Currently, the best solution is degradable tires (accounting for 18%). The final market choice data is the most convincing: In 2024, 93% of off-road users in the North American cycling community chose wide-tire models, while the repurchase rate of commuters in the European Union was 23% higher than that of standard vehicles, verifying its dual competitiveness in extreme environments and daily efficiency.
