Exactly what you want
Your review: Been using these for years. Compact folded but HUGE when expanded. Durable, dependable, versatile, reliable.
Pros: Stores so small, but opens up into whatever you need. Relatively light.
Cons: You have to learn which latch moves which handle, but that passes with experience. Get the larger wheel models if you'll be running off smooth pavement. Small wheels don't like uneven surfaces.
