I was super excited to get this bike at such a discount, but now I know why. It was a pain in the butt to put together, mainly because of the instruction booklet. It came with instructions for 4 different kinds of bikes, and had a QR code for each bike, but the one for THIS bike was cut off when printed so I couldnt get help there. The walmart page was of zero help and then I tried to look it up online and on youtube and EVERY search went straigh to a completely different brand/bike. THIS specific bike, was/is, nowhere to be found! This screams extremely suspicious to me with all kinds of red flags! We assume its put together, but it makes weird noises and doesnt get up to the speed ot claims. Just be cautious and safe with orders on here. I wish I had done my homework a little better.
