How we field-test
Run it past spec
Claimed range, torque, payload and build numbers get checked against what the unit actually does before we write a word.
Put mileage on it
E-bikes get ridden on hills and gravel, tools get bolted on, coolers get left in the heat — real use, not a five-minute demo.
Log the failure points
Where it slipped, overheated, rattled loose or fell short of spec goes in the write-up. Affiliate links are flagged; they never edit the verdict.
Spec sheets lie sometimes.
Mileage doesn’t.
