The 4.8-inch wide tire of the fat tire e bike (with adjustable tire pressure ranging from 5 to 15 PSI) reduces the ground contact pressure of the sand to as low as 0.05MPa (0.25MPa for mountain bike tires). Tests in Utah in 2024 showed that its climbing success rate on a 30° sand slope was 98% (while that of a regular eMTB was only 65%). The snow performance is equally outstanding: at -20°C, the tread hardness only increases by 18% (the hardness of ordinary rubber tires increases by more than 50%), and the Finnish Aurora Tour team measured that the speed through deep snow reached 15km/h (snowmobiles have a speed limit of 20km/h).
The passability of complex terrain has been significantly improved. The 190mm hydraulic front fork absorbs 94% of vertical impact (passing through a 10cm tree root at 25km/h), and the K-shaped structure of the rear suspension enables a roll Angle tolerance of 42° (75% higher than that of hardtail vehicles). Data from the 2023 Moab Cross-Country Race shows that it took only 8 seconds to climb a 35° rock face driven by an 85Nm torque motor (while traditional mountain bikes take 15 seconds), and the tire self-cleaning efficiency was 88% (the tire tooth clogging rate on muddy sections was less than 3%).
Intelligent optimization of battery life and power. The dual battery packs (with a total capacity of 1.8kWh) support hot swapping (completed in 5 seconds), and the energy recovery system (with an efficiency of 25%) enables a single-charge range of up to 120km (with a load of 100kg/ mixed terrain). The APP intelligently adjusts the output: automatically switches to BOOST mode on downhill slopes (instantaneous power 1.2kW), and activates ECO mode on flat roads (power consumption reduces to 8Wh/km). User data from Montana shows that this strategy reduces the range fluctuation rate to ±7% (±22% for traditional models).
The safety protection has been comprehensively upgraded. The gyroscope, in coordination with the TCS traction control (with a response time of 10ms), reduces the probability of skidding to 0.2 times per 100 kilometers (2.5 times for models not equipped). The IP68 waterproof motor (1 meter water depth for 1 hour) and ceramic bearings (reducing dust intrusion by 81%) have been verified in the Sahala Rally – all 32 participating cars achieved a 100% completion rate (the average for other teams was 78%). TUV Rheinland of Germany certified that its braking distance on slippery roads is 2.1 meters (friction coefficient 0.48), and the 300-lumen headlights at night reduce the accident rate by 57%.
The economic benefits have been commercially proven. Norwegian Post purchased 200 fat tire e Bikes. The delivery efficiency on mountainous sections increased by 40% (an average of 120 kilometers per day), and the frequency of tire replacement decreased from 3.2 times per year to 0.7 times. Compared with the Jeep Off-road (0.35 per kilometer), the operating cost of this vehicle is only 0.03 per kilometer (electricity + maintenance). The Yellowstone National Park Rental Station’s quarterly profit has increased by $150,000 due to the introduction of this vehicle (customer renewal rate is 83%). The EU life cycle report indicates that the wear resistance index of its specially designed tread is 600 (280 for standard tires), and it needs to be replaced only after 30,000 kilometers.
