I just put this together today, so all I can comment on is the ease with which I put it together. I'm almost 67, female, 5'9, and in decent shape. Being in shape means I could handle the roughly 70 pound box, but not without a dolly to get it from my front porch to my downstairs.The instructions are well-written, the bolts, nuts and so on are super well-packaged and well-labeled. I put it together by myself in just over an hour. But I've put lots of things together, so I'm fairly experienced.For those of you who are not, go slowly, and don't tighten anything up super tight until you're sure you've got it on correctly. I put the front stabilizer bar on upside down the first time, so the wheels were pointed up in the air, rendering them useless for moving the bike. I hadn't noticed the arrow sticker (see pics) but it was a super easy fix since I hadn't totally tightened it up.Be aware that some of the bolts are already attached to various peices of the equipment, not all of them are on the card that holds most of them.I love the wide seat, and the back rest is also comfy. The seat position is adjustable forward and backward, so I could easily set it to fit me: 5'9 with very long legs. I imagine it would adjust fine for folks shorter and taller than me.Hope the pictures I've included are helpful!
