How we score e-bikes
The Genius Score, explained — what goes into it and what it deliberately leaves out.
The Genius Score (0–100)
The Genius Score is a single, buyer-first number that blends two things: how capable a bike is in the real world, and how much bike you get for the price. It's always rated against other bikes in the same category, so a commuter is judged against commuters and an off-road bike against off-road bikes.
Data first: we normalize before we score
Manufacturers quote specs inconsistently, so before anything is scored we clean the data:
- Nominal vs. peak watts are kept separate — a "1000W peak" motor is not a 1000W motor.
- Weight vs. payload are kept separate — a 350 lb payload rating is not the bike's weight.
- Battery watt-hours are computed from volts × amp-hours when a brand lists only those, and dual batteries are summed.
- Claimed range is treated as the optimistic "up to" figure it is, not a guarantee.
Every value carries a confidence level and a citation to its source. If a spec isn't published, we mark it unspecified rather than infer a number.
The sub-scores (shown as stars)
Beneath the headline number, four capability sub-scores and a value sub-score break down the rating. They're shown as stars, rated relative to category peers:
- Range — usable real-world range for the battery and class.
- Power — how the motor and torque perform on hills and from a stop.
- Weight — how the bike compares to its peers (e-bikes are heavy; we judge it against its class, not in the abstract).
- Build — components: brakes, drivetrain, and the rest of the spec.
- Value — how much capability you get for the price, versus peers.
What the score is not
The Genius Score is not paid placement and not a manufacturer rating. Brands cannot buy a higher score, and our affiliate relationships never feed into it. It's also not a substitute for a test ride — it's a data-driven shortlisting tool to help you compare honestly before you buy.
Prices and specs change. Always confirm the current price and specification on the manufacturer's site before purchasing.
