How we rate
Every bike on Compare E-Bikes goes through the same process, so their scores can be compared with each other.
1. We collect the data
We start from the product listing on Amazon.com. When a figure is missing or contradictory, we look it up on the manufacturer's site, other major retailers or expert reviews, and note the source next to it. If no reliable source publishes it, we mark it "not published": we never fill gaps with estimates.
2. We score six areas from 0 to 10
- Range. Battery Wh and advertised miles with pedal assist, checked against reviews.
- Power. Rated and peak power, torque and top speed.
- Comfort. Suspension, tire width, geometry and riding position.
- Portability. Weight, whether it folds, and how easy it is to store or transport.
- Equipment. Brakes, display, lights, fenders, rack and extras.
- Value. What you get for what you pay, compared with the rest.
Scores start from fixed ranges for the whole catalog. For example, range is measured on a scale from 20 to 80 advertised miles and adjusted down if the battery's Wh don't back it up or reviews point to a lower real-world range. Power starts from peak power (500 to 2,000 W) and is adjusted for torque and top speed. Portability starts from weight (80 down to 45 lb) and gains points if the bike folds.
On top of that base we apply editorial judgment within one point, and explain it in each bike's review. The editor's score is the average of the six areas.
3. We read what buyers say
We look at the average rating, the star breakdown and the themes that come up most in Amazon reviews, and summarize them in our own words.
4. We keep it current
Prices change often, so every page shows the date they were checked. When we add new bikes, we review everyone's scores so they stay comparable.
