>>1854469i love it but they have some drawbacks. weight - that folding worksman is 50lbs, so you definitely want some gears. with 3 contact points on the ground, you will feel bumps more often, this is very noticeable on sidewalks that where the slabs are uneven due to tree roots pulling one up or just poor maintenance so a seat with springs helps.
overall i like them, been riding one for about a year now with no plans to go back. i still keep my old bike around but have only ridden it twice when i was having the trikes wheels trued. never got to try an electric one but i'd like to.
