From Laboratory to the Outdoors: The Reliability Testing System Behind PREETO

For an e-bike motor, power and efficiency are just the beginning. True reliability is proven in harsh environments — from freezing mountain trails to humid coastal cities, from smooth asphalt to rocky paths. PREETO knows that a product designed for global riders must withstand all of these conditions.

That’s why PREETO operates a dedicated reliability laboratory specifically designed for drive motors. In this lab, motors undergo rigorous validation protocols that replicate extreme real-world conditions:

• Multi-functional vibration testers simulate off-road bumps combined with variable temperatures, reproducing the stress of rugged mountain biking.
• Temperature and humidity chambers test performance across a range from -40°C extreme cold to 120°C scorching heat, ensuring consistent output under any climate.
• Thermal shock chambers measure tolerance to sudden temperature shifts, such as riding from shaded valleys into direct sunlight.
• IPX7-rated rain simulation chambers expose motors to heavy downpours, validating waterproofing and sealing reliability.
• Salt spray testers assess resistance against corrosion for riders near the sea or in winter road-salt conditions.
• Noise analysis systems ensure that motor sound remains stable and quiet, with ambient lab noise controlled under strict thresholds.

Every PREETO mid-drive motor must pass these automotive-grade endurance tests before reaching the market. For riders, this means no anxiety about weather, terrain, or distance — whether climbing in the Alps, commuting in humid Southeast Asia, or touring the California coast, PREETO motors deliver consistent, dependable performance.
