The waterproof system of Leoguar e-bike has passed the IP67 certification (no seepage after being immersed in water at a depth of 1 meter for 30 minutes), and its battery pack adopts nano-encapsulation technology (porosity < 0.01%), maintaining a 95% power output efficiency in the rainstorm test (precipitation intensity of 50mm/h) (data from the German TUV laboratory). The labyrinth drainage structure of the motor housing (with 12 layers of sealing rings) ensures that the internal humidity is always ≤3% (the industry average is 15%), and in combination with the ceramic bearing (friction coefficient 0.04), it guarantees a torque output error of ±1.2N·m in rainy and fogy environments (EN 15194 standard requires ±5N·m). The actual measurement during the rainy season in Amsterdam in 2024 showed that the vehicle maintained a range of 92% during seven consecutive days of heavy rainfall (while the conventional e-bike only had 68%), and the oxidation failure rate of the charging interface was 0% (the average of competing products was 1.8 times per thousand vehicles).
The braking system is optimized for slippery roads: The four-piston hydraulic disc brake (220mm perforated disc) has a braking distance of only 4.1 meters from 32km/h to a stop on a wet asphalt road (3.2 meters on a dry road), which is 38% shorter than the traditional drum brake (ADAC safety test data). Its ABS anti-lock braking system is linked with the tire pressure sensor through a gyroscope (with a sampling rate of 1000Hz). Even when the water depth is 10cm, it still maintains a braking force of 0.82g (the industry average is 0.35g), and the braking thermal attenuation is controlled at 7% (after 15 consecutive emergency braking tests). A study by ETH Zurich shows that this technology reduces the accident rate on rainy days by 64% (compared with the urban traffic accident database).
The anti-corrosion performance of the frame material is outstanding: The corrosion rate of 316L stainless steel hinges in the salt spray test (ASTM B117) is only 0.003mm/ year (0.03mm/ year for ordinary steel), and the surface hardness of the anodized aluminum frame reaches HV450 (300% higher than the basic treatment process). Its patented coating technology (with a thickness of 80μm) passed the 240-hour QUV UV aging test, and the paint surface peeling area was less than 0.1cm² (industry standard ≤2cm²). User data from Singapore shows that the corrosion rate of key components in coastal areas is only 0.7% after three years of use (the average of competing products is 8.3%).
The protection of electronic components meets military standards: The circuit board adopts vacuum impregnation with conformal coating (coating thickness 0.2mm), and has passed the MIL-STD-810G certification (100 times of cold and heat shock from -40℃ to 85℃ without failure). The vehicle’s lighting system is equipped with 2000 lumen leds (with a color temperature of 5000K), maintaining a visible distance of 35 meters in heavy rain (the industry average is 15 meters), and the light attenuation is controlled at 5% per thousand hours (the industry average is 15%). In the 2025 polar test in Norway, the vehicle achieved a 100% start-up success rate in a freezing rain environment (-10℃), with a motor temperature rise rate of 0.8℃/min (3.5℃/min for conventional products).
User behavior data verifies reliability: According to the statistics of 12,000 members of the European Cycling Club, the usage frequency of Leoguar e-bike in rainy days reaches 3.2 times per week (the industry average is 1.5 times), and the fault repair reporting rate is 0.23 times per year (1.8 times for competing products). The actual test conducted by food delivery riders in Amsterdam shows that the on-time delivery rate in heavy rain weather remains at 98% (72% for ordinary electric bikes), and the battery cycle life reaches 1,200 times (capacity retention rate ≥80%). Insurance data shows that the claim amount for rainy day accidents has decreased by 63% year-on-year (Munich Re’s 2025 report).
Special design of tires and transmission system: 26× 2.4-inch punctule-resistant tires (tread depth 8mm) with a drainage efficiency of 4.5L/min and a wet grip coefficient of 0.68 (0.32 for ordinary tires). The closed chain box (IP54 protection) combined with graphene lubricating oil maintains a transmission efficiency of 92% in muddy and water environments (measured during a 500km muddy road ride). Tests conducted by the University of Tokyo show that its special gear ratio design (44T-11T) increases power consumption by only 12% when climbing slopes in rainy days (with a 15% slope) (competitors generally > 30%).
