Hello community, bonjour à tous.tes!
I'm planning to put our bike inventory online and I was wondering what are the typical data that are relevant to inform potential buyers?
What are the key dimensions you would suggest? What is considered a "Large bike" for exemple. Or let's say someone is 6ft tall... What information would it best for them to find. Would you recommend the buyer to measure it's inseam?
Kinda looking for best practice here.
Thanks all, merci!

Hi Claude!
The most important measurement is the size of the bike, which is measured by the seat tube. This is not the "real" size of the bike, because that is more complicated, but for an online ad, this is the basic measure and lets the buyer know whether it's worth it to come in and look at the bike in person to check the rest of the fit. Most modern bikes have a sticker on the seat tube itself with the size, either in inches or centimeters. If the bike has this, great, let the manufacturer be responsible, you're done. Otherwise, measure the size as follows:
Generally, the grossest method of sizing a bike is to measure the seat tube in centimeters, from the center of the bottom bracket to the intersection of the seat tube and top tube. For modern bikes that have a sloping top tube, for instance those with "compact geometry", measure to where the intersection /would be/ if the top tube were horizontal. So in the latter case, make an imaginary horizontal line from where the top tube intersects with the head tube back to where it would intersect with the seat tube, and then measure from that intersection to the center of the bottom bracket. That number will be your "bike size" for your advertisement. See image attachments for examples.
As for your "tall people" question, most tall people already know their frame size, believe it or not. It's such a struggle for them too find a well-fitting bike that they've internalized that data at some previous point, so including the frame size in your ads means that potential buyers will self-select. Also see links below for some takes on sizes for different heights.
Other important bits of info for your ads:
- wheel diameter
- frame material (aluminum, carbon fibre, steel)
- brand and model
- type of bike (gravel, cyclocross, road, bmx, fixie, cruiser, mountain,
fat, ebike, touring, "kids'/children's", randonneur, city, cargo, etc.)
It doesn't have to be complicated. Unless you are offering shipping, most buyers are just looking a few bread crumbs that can persuade them to come in and see the bike for themselves.

Everyone To complicate things, children's bikes sizes are specified by the wheel size: 12", 16", 18", 20" and 24"inch. ByK bikes use the metric wheel diameter so 200, 250 (12") 350 (16"), 450 (20") , 540 (24") and 620 (26")
12" - eq is for preschoolers - up to 5yo or so 16" eq is for early primary school up to 7yo 18-20 is for middle primary - up to 9yo 24 is for mid to upper primary (9-11yo) and some small adults Small adult bikes (26" wheels) suit taller children and early high school (11to 13 yo) Then measure by frame size.
Here's the ByK guide.
