I am in search of the best folding bike to put in the back of my plane. The Blix Traveler looks possible and seems the lightest but will the battery really work to take me into town and back? Evelo is a bit heavier but how does one make this kind of choice? There are certainly a slew of others but most are well over 40 lbs which is the max weight I want to carry in the plane. Any suggestions?
