So I'm on a mission to purchase and modify a utility bike fully equipped with chain guard, fenders, rear rack and perhaps a front basket. However, I live on the third floor of an apartment and I want to make the bike a light as possible, preferably under 30 pounds. Since the specs of most bikes don't list weight, I'm planning to weigh things myself, possibly even weighing bikes in bike shops.
In addition to weighing the bikes themselves I'll be weighing accessories such as baskets and racks. I'll also be weighing my current bikes to have a comparison.
I'm aware that I could easily weigh a bike by standing on a standard bathroom scale and subtracting the difference. I'm more interested in a luggage scale or something similar, but I want to make sure it is suitable for weighing weirdly shaped components like fenders.
What scale would you recommend I purchase? Much appreciated.
