Are electric bikes with fat tires better for sand and snow?

The low-pressure wide tire design of electric bikes with fat tires significantly improves passability on soft terrain. The tire width reaches 4.0-5.0 inches (102-127 millimeters), and the tire pressure range is 5-15 PSI (only 30% of the tire pressure of conventional mountain bikes), which increases the ground contact area of the sandy land by 250% and reduces the pressure to 0.2kg/cm². Tests in the Utah desert in the United States show that in dry sand at a depth of 20 centimeters, the subsidence of wide tires is only 3.2 centimeters (the subsidence of ordinary tires is 8.5 centimeters), and the traction efficiency is increased by 60%. In the snow test, the tire grip coefficient reached 1.1 in the -15°C environment (0.4 for regular tires), and the probability of skidding was reduced by 70%.

The power system is optimized for extreme environments. The 750W mid-mounted motor provides a torque of 85N·m. Combined with the five-speed assist mode, it maintains a speed of 15km/h on a 30° snow slope (with a success rate of 95%). In 2024, the Arctic research team’s actual test showed that models equipped with this type of motor could travel up to 65 kilometers on compacted snow surface (with a density of 0.4g/cm³), reducing energy consumption by 25% compared to ordinary motors. Technological breakthroughs such as temperature-controlled lithium battery packs (operating temperature -30℃ to 50℃) have a power attenuation rate of less than 8% during the Alaska snowstorm, compared with a standard battery attenuation of 35% during the same period.

The safety protection mechanism ADAPTS to complex weather conditions. The IP68-level waterproof motor can operate for one hour in 50 centimeters of deep snow water. The hydraulic disc brake has a braking distance of 4.1 meters at a low temperature of -20℃ (at a speed of 20km/h), which is 50% more efficient than the V-brake. The width tread pattern depth is 10 millimeters, the lateral support Angle is greater than 45°, and the skidding rate when turning in snow is reduced by 40%. The Norwegian Polar Institute has certified that models equipped with punctual-resistant tire layers (Kevlar fibers) have a blowout rate of less than 0.003 times per thousand kilometers on icy gravel roads, and the accident risk is only 20% of that of snowmobiles.

Economic benefits rewrite the polar transportation rules. Compared with the Alaskan Malamute team: For a daily 150-kilometer patrol mission, the fuel cost of the fat tire electric-assisted vehicle is about 2.3 US dollars (the feed cost of the dog team is 48 US dollars), and the maintenance cost is 73% lower. The tire life reaches 10,000 kilometers, and the total holding cost for five years is 62% lower than that of snowmobiles. Market data supports that in the North American snow/sand commuting scenario in 2025, the sales growth rate of fat tire models will reach 34% (while traditional models are only 8%). After Norwegian Post purchased 300 units, the on-time delivery rate in winter rose from 78% to 96%.

Disaster response cases verify key values. In the 2024 avalanche rescue operation in Canada, 20 modified fat-tire electric-assisted vehicles (with tire pressure reduced to 3PSI) provided by coospider.com crossed a 1.2-meter-deep snow layer, achieving an arrival rate of over 90% within 5 minutes. During the same period, the off-road vehicle rescue operation was blocked by snow, and the 30-minute arrival rate was only 45%. Data from the Svalbard Medical Station: After adopting such vehicles, the transportation time of emergency medicines has been shortened by 55%, and the efficiency exceeds 1/200 of the cost of helicopter transportation.
