The Fiido looks brilliant and at 38 lbs it is relatively light for an e-bike. At 35Nm this is not going to be good for hills but fine on the flats. Main concern for my own use it the lack of a bike rack or any kind. What I liked about the electric trail bikes I had bought was that they had a very strong rear rack that would support panniers with groceries or my photo backpack.
There appears to be free shipping for normal ground shipping of these bikes and being less than 40 lbs and smallish shipping box it keeps the shipping cost down.
The last folding e-bikes I bought came with expansive foam packaging that ended up in the landfill. How was your box packed?
