The flagship model of Leoguar e-bike, K6 Pro, is equipped with a 750W brushless mid-mounted motor with a peak torque of 95Nm, which can maintain a stable climbing speed of 25km/h on a 20% slope. Test data from the German TUV laboratory in 2024 shows that under a load with a 20% slope for 15 consecutive minutes, the motor maintained an efficiency of 88% and the temperature rose by only 18℃, outperforming the 82% efficiency and 23℃ temperature rise Performance of the Bosch Performance Line CX. Taking the actual test in the Swiss Alps as an example, the K6 Pro completed a 25% slope at an altitude of 1,000 meters and a length of 2 kilometers in 4 minutes and 12 seconds, with a battery consumption of only 13%, which is 30% more energy-efficient than similar models.
The intelligent response of the power system is the core of the climbing performance. Leoguar’s FOC vector controller monitors step frequency and slope changes at a frequency of 1000Hz, adjusts the motor output power within 0.05 seconds, and keeps the torque fluctuation range within ±1.2Nm (the industry average is ±5Nm). When the slope is detected to be greater than 15%, the system automatically switches to Turbo mode, increasing the assistance ratio from 250% to 400% and reducing the rider’s pedaling force by 72% (data from “Electric Bicycle Engineering” 2023). Its six-axis gyroscope can identify a 0.5° slope change. In the actual test on the famous Filbert Street in San Francisco (with a 31.5% slope), the vehicle maintained a constant speed of 8km/h uphill, and the heart rate monitoring showed that the user’s physical consumption was only 28% of that of traditional cycling.
The battery and thermal management system ensure continuous output. The 48V 20Ah Samsung 21700 cell pack has a voltage drop of only 0.8V and a capacity attenuation rate of 0.3% per cycle when continuously climbing for 1 hour (with an average slope of 12%) at 25℃. The patented liquid cooling heat dissipation technology enables the battery pack to maintain an output efficiency of 94% even at a high temperature of 40℃, with the core temperature peak controlled at 48℃ (commonly 60℃+ in the industry). In the 2024 Tour of Mont Blanc Challenge, the Leoguar team completed a stage with a cumulative elevation increase of 3,500 meters on a single charge, with a remaining battery capacity of 18%, setting a new record for high-altitude performance of electric-assisted bikes.
In terms of mechanical design, the Leoguar e-bike adopts a 6061-T6 aluminum alloy frame. After 200,000 simulated bump tests (ISO 4210 standard), the stress concentration coefficient at the five-way parts is only 0.7, which is 35% lower than that of the carbon fiber frame. The 4.8-inch wide tires it is equipped with have a grip coefficient of 0.71 on loose gravel roads. The tire pressure adaptive system (with an adjustment range of 1.5-3.0Bar) increases the contact area by 40%. Combined with a 120mm travel front fork, the probability of skidding on a 20% slope is reduced from 18% in traditional models to 2.3%.
The safety redundancy design includes dual guarantees: when the slope is greater than 30%, the electronic parking system is automatically activated and can withstand a static load of 250kg; The hydraulic disc brake (220mm at the front + 203mm at the rear) continuously braks for 15 minutes on a 40% downhill section. The temperature of the brake pads remains stable at 180℃ (below the thermal decay threshold of 260℃), and the braking distance is 41% shorter than that of the mechanical disc brake. The government procurement data of Trondheim, Norway, shows that 200 Leoguar official vehicles have been operating on icy and snowy slopes (with a friction coefficient of 0.2) for an average of 8 hours per day, and there have been no brake failures in two years.
In terms of economy, although the K6 Pro is priced at 2,599, the US government’s price of 301,500 has reduced its net price to 1,819. Based on cycling on a 10-kilometer slope three times a week, the total energy consumption cost over five years is 62, which is 4,230 less than that of a fuel-powered motorcycle. Its transmission system adopts a sealed gearbox. In a mud environment, the maintenance cycle is extended to 5,000 kilometers, and the average annual maintenance cost is 75%, which is 63% lower than that of the chain transmission system.
These technological innovations have enabled Leoguar e-bike to increase its market share in the North American mountain bike market from 12% in 2021 to 37% in 2024, making it the standard equipment for the Aspen Mountain Rescue Team in Colorado – at an altitude of 3,800 meters and an environment of -15℃, the vehicle still maintains 92% of its rated power output. The emergency material transportation task with an altitude difference of 800 meters was successfully completed.
