We bought this bike because my wife has balance issues, and riding a two wheeler is not feasible any longer. It’s very stable, and also has just the right ergonomics for her: she’s 4’-11” tall, and the seat to pedal distance, after adjustment of seat height, is perfect for her leg length. It’s also easy to get into the cockpit and up on the seat, because the down tube is curved; there is no top tube. All components were very well protected by the excellent shipping packaging. The trike comes pre-assembled into very easy to complete modules- bottom bracket, crank arms, and main chain assemble already put on the main frame for you. Headset already installed into headset tube, ready to go! No special bike tools needed. The rear frame and secondary chain goes on easily with 4 hex nuts. I liked the liberal use of thread locker on many of the fasteners!
