When it comes to e-bike performance, many riders think first of torque or efficiency. But there’s another factor that quietly shapes the riding experience: weight. A motor that is powerful but heavy can compromise handling, agility, and overall comfort. PREETO’s engineers set out to solve this by pursuing lightweight design without sacrificing strength.
PREETO adopts high-strength aluminum alloys and engineered polymers in non-load-bearing parts, significantly reducing overall mass while maintaining durability. For critical components such as the gear set, PREETO uses powder metallurgy with precision sintering, striking a balance between toughness and reduced density.
Through finite element analysis (FEA), engineers simulated thousands of stress conditions to refine the motor housing and gear structures. The result: designs that use less material without compromising reliability.
The motor integrates controller, sensors, and cooling pathways within a streamlined casing. This reduces the need for external modules, saving not only weight but also installation complexity.
With these innovations, PREETO achieves a 20% reduction in system weight compared to conventional mid-drive motors of similar power ratings.
For the cyclist, this means:
In short, PREETO proves that lightweight and high-performance can coexist, giving riders the freedom to enjoy both agility and power on every journey.
