Ultra lightweight 17lb Aceoffix C5 build for $1500 all-in (taxes + tariffs) - Brompton T-Line alternative
I have a Brompton electric that I love, but I wanted something lighter that I'm willing to lock up outside at the gym (so not crazy expensive like the T-Line) and that I can also carry around for multimodal commutes with lots of stairs. Additionally, the fold had to have just as small of a footprint as a Brompton, as I'd love to fly to Europe/Asia and pack it in check-in luggage.
So here's my ongoing Aceoffix C5 build, which weighs less than the 4-speed T-line, despite including a rack and fenders. I went with Aceoffix b/c a fairly knowledgable youtube made a video about it and because its fold was exactly the same as a Brompton, whereas some other bikes seemed to have slightly larger folds and I was concerned about being able to pack those.
