Send a correction
43 bikes, 16 brands, 7 categories, and a market where a brand can revise an entire lineup between spring and autumn while keeping the model name. Some of what is on this site is already behind. The quickest way to find out which part is for somebody who owns the bike to say so.
What is worth sending
A spec that doesn't match the maker's page
Motor wattage is the field most often mismatched, because a maker's spec page carries the nominal rating and its own marketing carries the peak, and the two are hundreds of watts apart. Battery capacity is the other, quoted as watt-hours in one place and as amp-hours at some unstated voltage in another. Say which bike and where the right figure lives. It gets read off the manufacturer's own published page before anything changes, and a corrected number does not sit still: the head-to-head table picks a per-row winner straight from these numbers, so one fix re-decides that row across every matchup the bike appears in.
A class designation that's wrong for where you ride
Class 1, 2 and 3 is the field least likely to survive the trip from spec page to driveway, because a bike can ship configured one way and be sold as another, and because what each class may legally do is set state by state rather than by the maker. The class recorded here is the one the manufacturer publishes. If your bike arrived speed-limited differently from what the spec page says, that is worth a message: class is one of the filters on the list, so a wrong one drops a bike out of a shortlist it belongs in and into one it does not.
A bike that should be listed and isn't
Send the model name and a link to the maker's spec page. A bike joins the catalogue only once every tracked field can be read off a published source — motor, battery, claimed range, top speed, weight, max load, brakes, drivetrain, wheel size, warranty — because a half-filled entry shows up as blank cells in each of the 53 matchup pages that bike would then be pulled into, and on its brand hub.
A range figure that doesn't survive contact with a hill
The range on every bike page is the manufacturer's claim, and those are measured in the lowest assist mode by a light rider on flat ground. A year of commuting on one is better evidence than the number on the box. What you send goes into the owner notes on that bike, which is where the argument about real-world range belongs — the spec row keeps saying what the maker says, clearly labelled as such.
A price that has moved
The prices here are list prices from the August 6, 2026 refresh, and direct-to-consumer e-bike brands discount so constantly that a price is only useful as a tier. If a bike has settled well outside its band, that matters more than it sounds: the price filter is a band filter, so a stale figure quietly shows the bike to the wrong shopper.
Who reads it
Two people run eBike Ranker. There is no office, no test fleet and no lab; what stands in for one — manufacturer spec sheets for the numbers, public owner discussion for the complaints — is set out on how this site works. Both of us get every message, and a reply comes from one of us rather than from a queue.
What a message will not buy
No bike brand pays to be here and none has ever been asked for money. There is no sponsored slot, no paid placement, and no arrangement in which a rank moves. A bike sits where it sits because of its price or whichever column the reader chose to sort on. Brand enquiries are welcome; the answer to the one about ranking higher is the same every time.
When nobody publishes the number
A field nobody publishes is left blank rather than estimated, and the matchup table is built to cope with that: a row where either bike is missing a figure declares no winner instead of treating the blank as a zero and handing the other bike a free point. As of the August 6, 2026 refresh all 43 bikes have every tracked spec filled in, so that rule currently has nothing to do — which is the honest version of the claim, not a boast that gaps never happen.

The form below goes to the same place, but if you would rather write directly, use chelsea@hagadornwebdev.com. A model name in the subject line saves a round trip.
Writing in subscribes you to nothing. Your address carries an answer back and stops there — no bike brand, no dealer network and no list is told who questioned a range claim.
