"Heavy" was also one of my main concerns when browsing through foldable e-bikes, I wanted a foldable one for easy transport and storage, I live in an apartment and don't have a garage. I've honestly found CARBO to be a quite viable option and 5 months into my purchase, I am enjoying it very much! It's surprisingly SUPER light, fully made of carbon fiber and at a low price considering the quality it provides.Thank you, "A". I did do a little research on the "Lectric". I believe it is also rather heavy. Seems like most of the ebikes are rather heavy. I am impressed with the NYC popularity of the bike though. Maybe I need to look at it again. I really like the Riese and Muller Tinker, but not the price. I am looking at the compact bikes primarily because they are easier for me to get off and on. Don't really like the "step-through", but I may have to go that route. I have difficulty throwing my leg over the taller bikes. The Z20 is kinda cute, I'll check it out.
