I have seen a few posts on here advising people against the use of walmart bikes in MB projects. I am here to dispel the negativity. I have a Huffy Cranbrook that was purchased at walmart approximately a year ago. I had a spare ignition magnet laying on the floor of my garage, and I took it to my bike. The frame and the rims are all made out of steel. The welds are pretty strong, too. I have not had any issues with my frame or rims in the year that I have been using this bike as an MB. Anyone else care to share positive experiences with walmart bikes?
