The Planet Bike Anatomic Relief Saddle is re imagined with new Lift technology to make this the most comfortable bike seat you can own! The cambered enhanced cushioning design gives extra support to your sit bones while minimizing pressure on any soft tissue. That makes this seat super comfortable, allowing you to push back into padding and away from anything tender. This is especially important if you are riding an Electric bike and don't stand up at all to pedal! The deep channel down the middle provides additional comfort, and the dampening inserts allow you to feel the comfort all the way through the saddle. The design is enhanced with Lift technology. The cambered cushion design reduces pressure on your sit bones. The addition of the Lift handle makes it easy to pivot, and move your bike, whether out on a ride or in your garage. There are two sizes to the A.R.S. Lift saddle, the 215mm designates the width of the seat. The A.R.S. Lift bicycle saddles are designed for recreational, leisure, commuters, and E-bike cyclist looking for a wider platform and an extra amount of cushion and shock absorption. There is no reason to be uncomfortable on your bike anymore!
