The quality is good for the price. Might get another one as a gift.

Got the bike in about 4 days. It was almost all put together. It was ready to ride in 30 min and felt great.

Second one!

After buying a White 36v fat tire bike for my wife to take RVing I bought this one for me. It also came with no shipping damage. Just as easy to assemble as the first one was. There are YouTube videos to watch which will help with the little bit of assemble needed. I love the display on the 48v model. If you have the extra $ go with the 48v model. I can say Wife is enjoying her 36v white one. Can't wait to use them on vacation RVing this summer.
