Yup. That's how I weigh my bikes. It still takes a bit of "engineering". I run a ulock through the top bracket of the scale to hang it on my workstand and then hang the bike from the hook using a Velcro strap I got at REI.

I think my 2013 Jake weighs about 26 pounds with rack and fenders but no luggage. At the other end of the scale, my 2013 Jake the Snake singlespeed weighs exactly 18 pounds with no rack or fenders. Most of my other bikes are between these two. I think my Long Haul Trucker is the only one outside the range. It weighs 35 pounds before I start loading it.
