Just got the Magnum Cruiser low rise - which is really a mid-step. I have numerous back issues including damage to my lumbar spine from an infection, a broken neck In my cervical spine and moderate spinal scoliosis. At 67, all the chemotherapy and radiation from cancer treatments in my 20s has stiffened my heart and I have to be careful with exertion. The Magnum was perfect for me. Incredibly comfortable from the pedal forward design, love the tool-free adjustable handlebars, the powerful motor and the big battery. Just came back from a 30 km ride which included some steep hills and only used 1/5 of the battery. Nothing hurts! Very happy and highly recommended. My wife is really thrilled that I’m out riding with her again.
