What are people's experiences with folding e-bikes? I'm most interested in the Gocycle, but it costs as much as a used car. This Siggi https://www.indiegogo.com/projects/siggi-unfold-everyday-lif... looks great and only weighs 13 kg but has all the risks of a crowdfunding project (massive delays and initial quality issues). It's the first I've seen with regenerative braking, and you can pedal backwards to charge it.
