Strengths: A long pedal crank for good torque. Close to the ground for easy mounting. High handle bar, for upright pedalling.
High
Weaknesses: Limited to riding on pavement. Low clearance can cause pedals and frame to hit the ground on sharp turns. No basket will mount to front axle.
Bottom Line:
Easy to mount and most comforatble at low speeds. At age 70, I can highly recommend it for older people who have health problems but are are still agile. With an artifical hip, I can still ride because of the upright pedalling position.
