This is the stock saddle used on our Aventon Pace 500 and Pace 500 Step-Through ebikes. It features standard rails so you can upgrade many other makes/models, too.
Aventon Pace 500 Saddle
I had bought a second one thinking I was upgrading. I did not read the ad close enough, it is the same saddle that comes with the bike. I probable will never need a second one, but you never know. The Aventon people are great, helpful and prompt, and the Pace 500 is awesome!
Fun bike to ride, love the smaller, lighter size. The brakes are noisy and not great.
