There's the Mylo etrike, which has a tadpole design (two front wheels), so it's far less likely to tip over than a delta style (two rear wheels). Unfortunately it doesn't have any pedals, so not sure if that's street legal in the EU (also unfortunate if the battery dies, though you can attach two batteries to it.) If I hadn't already bought an ebike earlier this year (not knowing about the Mylo etrike), I'd probably consider it though, as it folds up nicely, can carry a passenger, and seems a lot less likely to tip over (straights or turns) than a regular ebike. Hopefully with Rad making etrikes now, they'll consider something like that but with pedals in the future.
