The Defiant Fat Tire bike is so much fun to ride. You can take it anywhere beach, trails, road and it rides perfectly. I like it so much I bought one for my wife so we could explore and have fun together.

Great product at a great price. Directions were very detailed and understandable. My only complaint would be details about the new headlight.

The new front shocks on my Defiant bike make the ride smoother, and give it a nice look. However, I struggled with the instructions in the upgrade kit. I recommend watching the YouTube video that customer support shared with me: https://m.youtube.com/watch?si=j_pNiTtO6nMy8wYY&v=28rcv4opFYQ&feature=youtu.be. Two tricky parts of the process are 1) installing the new headlight and 2) when reattaching the brake caliper, you have to remove a bracket completely that is no longer needed for this new front fork. The paper instructions missed the mark in my opinion. The video, however, is good.
