Methodology
How We Score Electric Scooters
Every scooter in the ScooterRank database receives an overall score from 0 to 100. This score is built from seven performance dimension scores, each calculated using a percentile-based method that compares the scooter against its closest peers.
The 7 Scoring Dimensions
The overall score is a weighted average of the following dimensions:
Power & Speed
Peak motor power and top speed versus subcategory peers
Range & Efficiency
Claimed range and battery capacity versus peers
Ride Comfort
Suspension setup, wheel size, and adjustable suspension
Portability
Weight (lighter = better) and foldability bonus
Safety
Brakes, lights, IP rating, and turn signals
Tech & Features
App connectivity, OTA updates, GPS, NFC anti-theft
Build Quality
IP water resistance, brake type quality, suspension quality
* Default weights shown. Site administrators can adjust weights via settings — current weights are reflected in the live scores.
Value for Money (Informational)
A Value for Money score is calculated separately and displayed on every product page as a reference metric. It measures overall score per dollar — a scooter that scores 65/100 and costs $500 has better value than one that scores 65/100 and costs $900.
This metric is not included in the Overall Score for three reasons:
- Products without listed pricing would be unfairly penalised.
- USD prices don't reflect value equally in all markets.
- Price changes frequently; the overall score should remain stable.
You can browse by value on the Value for Money ranking page.
Percentile-Based Scoring
Each dimension score represents a percentile rank among comparable scooters. A score of 70 means this scooter outperforms 70% of scooters in its subcategory for that dimension. A score of 50 is average.
This approach means scores are always relative — as new models are added to the database, scores may shift slightly. A top-of-range performance scooter added to the database may push other performance models' power scores down.
Subcategories
Scooters are grouped into subcategories for fairer comparisons:
Budget
Entry-level under ~$400
Commuter
Mid-range daily riders
Performance
High-power, high-speed
Off-Road
Wide tires, full suspension
A budget scooter scores against other budget scooters — not against a $3,000 performance model. Products without a subcategory are compared against all products in their category.
Community Range Data
Manufacturer range claims are often optimistic. ScooterRank collects real-world range reports from owners. Submissions that fall within plausible bounds are validated and displayed alongside the claimed range on every product page. Outlier submissions receive reduced weighting in the average.
Data Sources
Specs are sourced from manufacturer pages, official user manuals (PDFs), and retailer listings. AI extraction is used to parse manual PDFs — all extracted data is validated against manufacturer specifications before publishing.
