Difference Between the R2 & R1 Carbon Seats Read Before Purchasing

Why I created the R2 Carbon—for riders who need even more comfort, plan to ride over 30 miles, or find narrow seats uncomfortable. If that sounds like you, the R2 Carbon will be the ideal choice!

From my testing, the R2 Carbon performs exceptionally well for long-distance rides—I rode nearly 70 miles without discomfort. However, since it’s wider than the R1, it’s better suited for riders who use throttle more often than pedaling. The extra width provides superior comfort but can make pedaling a bit more challenging.

My goal is to design the best possible seat for every rider so that you can enjoy the most comfortable ride.

The R1 Carbon seat is perfect for riders looking for a significant comfort upgrade from the original seat while maintaining a sleek design. It’s ideal for those who frequently pedal, cruise around town, or ride on dirt trails. The extra padding absorbs bumps, making it far more comfortable than the stock seat.

One of the key design goals was to keep a narrow profile to match the bike’s aesthetic. However, due to this design, there are some limitations to long-term riding comfort. Based on my testing, mild discomfort starts setting in around 20-30 miles, though it's still a huge improvement over the original seat, which becomes painful after just 6 miles. Comfort is subjective and depends on body type, but for most riders, the R1 Carbon offers a much better experience than the stock seat.
