Leoguar’s electric bike for adults series is specially designed for adults. The frame size covers the range of 510-650mm (ISO 4210 standard) and is suitable for cyclists with a height of 175-205cm. Its patented adjustable seat tube supports 135mm vertical adjustment (±0.5mm accuracy), combined with 780mm wide handlebars (±15° Angle compensation), it keeps the riding posture Angle of users with an arm span exceeding 200cm stable at 35°±2° (data from the Dutch TNO Ergonomics Laboratory). The 2024 Berlin Cycling Club’s actual test showed that a 198cm tall rider, after continuously cycling 50 kilometers, had a lumbar pressure index of only 12.3kPa (the average of traditional models is 18.7kPa), and the knee flexion Angle error was controlled within ±0.8°.
The structural parameters of the vehicle body have been optimized: the extended aluminum alloy frame (tensile strength 520MPa) has a wheelbase of 1250mm (18% longer than the standard version), and combined with the rear floating seat tube design (with a rear displacement of 45mm), it enables cyclists with legs longer than 110cm to obtain an effective pedaling travel of 72cm (the industry average is 65cm). Vibration tests by the German TUV laboratory show that its carbon fiber front fork (rigidity index 92Nm/deg) combined with the dual-chamber shock absorber (stroke 120mm) can reduce the road surface impact by 89% (at a frequency of 5Hz), and the hand vibration on the gravel road surface is reduced from 6.2m/s² to 0.7m/s² (ISO 2631 standard).
Targeted upgrade of the power system: For high-weight users (≤150kg), the peak torque of the enhanced mid-mounted motor has been increased to 110N·m (certified by EN 15194), maintaining a speed of 25km/h in a 15% slope test (with an efficiency of 92% when carrying a load of 130kg). The adjustable five-speed assist mode (250-1000W) automatically ADAPTS the cadfrequency (50-110rpm) through algorithms, enabling a user with a height of 195cm and a weight of 100kg to achieve a range of 135km in mixed road conditions (NEDC standard), with an energy efficiency 27% higher than that of standard models.
The ergonomic accessory system includes: an extended floating seat cushion (length 320mm, memory foam density 65kg/m³), a six-way adjustment system (front and back ±50mm, Angle ±8°) to adapt to different pelvic widths (120-160mm). The optional telescopic handlebar riser (with an adjustment range of ±40mm) and adjustable pedals (with a height difference of ±15mm) enable cyclists with different torso proportions to achieve the golden triangle ratio (the distance ratio of seat cushion – handlebar – pedals is 1:0.85:0.9). According to biomechanical research at ETH Zurich, this design reduces the load on the core muscle group of users with a height of 190cm by 37%.
User data verification of comfort: Leoguar’s North American market research shows that the net promoter score (NPS) for users with a height of 185cm or more reaches 82 points (the industry average is 54 points), among which the satisfaction score for seat support is 91% and the score for legroom extension space is 93%. During the 30-day actual test conducted in Amsterdam, cyclists with a height of 201cm covered an average daily cycling distance of 28 kilometers (the average distance for users of ordinary vehicle models was 19 kilometers), and their muscle fatigue index decreased by 41% (surface electromyography signal analysis). After-sales data shows that the three-year failure rate of this series of models among people over 190cm in height is only 0.7 times per thousand vehicles (the average of all users is 1.2 times), and the warranty claim rate of the frame structure has decreased by 63%.
The pricing strategy reflects the professional positioning: Although the frame customization service increases the base selling price by 18% (2,850vs the industry average of 2,400), the 5-year maintenance-free cycle (2 years for regular models) reduces the cost per kilometer of use to 0.11 (0.19 for competitors). The modular design supports later upgrades (such as extending the carbon fiber seat tube by 15%), and the cost of modification accessories is 62% lower than that of vehicle replacement. According to the 2025 survey by J.D. Power, the annual comprehensive holding cost of tall users is 29% lower than the industry average, and the five-year residual value rate remains at 68% (52% in the industry).
