    I was hoping for a large framed bike so I could stretch my legs. This is a basic small bike frame that happens to have large tires.

    Out of shape, want to ride down trails or go to the store this is my ride. Put it together in less than a hour. Comes with a manual Yes I read the directions on everything and you should too. Took about 45 minutes to do the fine tuning and away I went, I did forget how out of shape I am [that is not the bikes fault ] If you are not comfortable with hand tools ship it to the store and have it assembled, better safe than sorry Keep in mind that this is a 29" bike. The package was not great but other than the holes in the cardboard no damage.

    This would be a good bike if it would have arrived in one piece. Unfortunately the front tire has a broken spoke so I didn't even unpack the unit from the plastic ties they use to ship the unit in the box. The bike arrived fast considering it had to travel 1/2 way across the US to Florida. The box was damaged on the one side and the copper color staples used to seal the box were all undone. What kept everything closed were the two plastic bands they use to seal the box. I find it hard to believe they would have shipped it unsealed like this from the warehouse but who knows? Maybe it was a returned unit and some one didn't see the problem and shipped it back out. I called the help number but they are closed on Saturday. I will call on Monday to see if they will rectify the problem; if not, it will be returned to Walmart. The good news, I was impressed when the unit arrived 4 days earlier than their shipping time estimate. The bike has a wonderful green metal flake paint job, alloy rims with 29 x1.95 (700 x 50c) blackwall tires. It is an all steel bike with a nice chrome finished front fork and a according to my bathroom scale with all its parts weighs only 38.7 lbs. I still hope to get one put together soon to further evaluate this bike . Note this bike comes with basic tools to put bike together including a multi-purpose wrench and two allen keys. Nice touch Walmart and Mantis!
