100%
In-House Development
The PREETO systems are developed and produced 100% inhouse, ZHAOWEI has the full control from start to finish.
We use same automotive design and test standards to develop and manufacturer all PREETO systems.
All the gears are designed, tested and manufactured by ZHAOWEI inside ourself.
OWN TESTING LABS – Precision, Performance & Reliability
At PREETO, quality and durability are at the core of our e-bike systems. Our in-house testing laboratories conduct rigorous assessments, ensuring every component meets the highest standards for durability, vibration resistance, impact resilience, dustproofing, waterproofing, and electromagnetic compatibility (EMC).
Precision Engineering for a Seamless Riding Experience
PREETO’s high-precision manufacturing technologies set a benchmark in e-bike performance. Our specially grounded gear systems detect even the slightest rider movement, adapting instantly to changing terrain and conditions. The result? Ultra-responsive power delivery within milliseconds for an intuitive and controlled ride.
Uncompromising Quality & Safety
Built on decades of automotive expertise, PREETO’s quality control process follows the same stringent protocols as our ABS brake system manufacturing, with over 100 million ABS components produced. We adhere to the highest safety standards (EN15194:2017), ensuring absolute reliability in every ride.
Engineering Optimization for Peak Performance
Our engineers utilize advanced multi-objective optimization to refine motor performance:
Minimized cogging torque & back-EMF harmonics for ultra-smooth operation
Enhanced rotor design for increased air-gap magnetic flux density, boosting torque output
Segmented stator structure to maximize the slot fill factor, reducing energy losses
Integrated overmolding technology for superior heat dissipation, ensuring sustained high-power performance
Intelligent Ride Control – Real-Time Adaptability
PREETO’s multi-sensor integration brings intelligent ride control to the next level. With a three-axis sensor, torque sensor, wheel speed sensor, and cadence sensor, our advanced real-time algorithms analyze rider input and terrain conditions instantly. The result? Seamless power adjustments for stable, responsive, and natural pedal assistance across all riding environments.
