Along with the mesh, is a pleasant amount of padding on the bottom of the seat. It weighs a total of 125 pounds, therefore this bike is a very stable ride.

Not everything can be perfect not even the Diamondback. There are a few flaws and kinks that need to be addressed and taken note of.

  • The assembly process can be a bit tedious; but for a few extra bucks it can come assembled and placed exactly where you want it.
  • Some customer reviews have commented on the LCD display screen. It can be a little hard to read under dim lighting.
  • Some instances, customers have noticed their seats were somewhat wobbly no matter how tightly they skewed it in. The wobbly seat can, therefore, make the seat squeak.

Most reviews were typically positive and enthusiastic. Any reviews with a negative complaint mentioned that they replaced whatever was defected (due to the amazing warranty) and were generally happy with this model.
