How We Score eBikes

At eBikes.com, we believe in complete transparency. Our Editorial Scores are not influenced by sponsorships or brand partnerships. They are calculated using a strict, data-driven logic gate based on manufacturer specifications:

⚡ Power Graded strictly by Motor Wattage. A baseline 250W earns an average score, with higher continuous outputs scaling linearly to the maximum score.
🗺️ Range Graded by Battery Capacity (Watt-hours). A standard 300Wh battery serves as the baseline, rewarding bikes that offer extended range capacities.
🛋️ Comfort Calculated by suspension type (Full, Front, or Rigid) and frame geometry (Step-Thru vs. Step-Over) to determine overall ride smoothness.
🛠️ Build Quality Assessed via component tiers. Bikes receive premium marks for Hydraulic Brakes, UL 2849 safety certifications, and premium price-tier construction.
