From 2017:
https://www.bikeforums.net/commuting...-weighing.html
1997 Nishiki Blazer 49.5 lbs
1984 Nishiki International 32 lbs
2015 Charge Plug 39 lbs
Since then I put drop bars on the Blazer which saved about 5 lbs.
I also added a
Dahon Boardwalk 20" folder which is about 30lbs equipped
16" Dahon GetawayV, also 30lbs
2006 aluminum/carbon Felt F86 which is about 19lbs
I myself dropped 9 pounds since 2017. I think that's due to less muscle and less food intake due to a shorter daily commute, less distance riding and age (now 62).
