This is a big problem for everyone with e-folders. A to B Magazine are folder and e-bike specialists with huge experience and their honest opinion is that no e-folder yet is truly portable, 15 kilos upwards being too much to carry for any length of time or up flights of stairs.So this puts a big question mark on top of the K16 as I have never ridden in London weather without mudguards...
I am getting more and more confused every day about how to choose a folding e-bike that actually fits my need..
If I go for the Secret I get all the above but loose the opportunity to carry it on tube/train and it's heavier to lift up the stairs.
If I go for the K16 I got lightweight and portability but no mudguards/lights/bell.
And even at 15 kilos there's lots of compromises like being ill-equipped and having small wheels. The only really universally good e-folders have full length frames, 20" wheels and full equipment. I had one, but it weighed over 25 kilos and was even difficult to put into the car boot.
It's a fundamental design problem with the materials available at sensible prices,
