Schwalbe Marathon Racer 20x1.50 (40-406) HS429 Tire - The most popular recumbent trike tire by far. There is a reason that this tire is the default stock option on so many recumbent trikes. Every tire is a compromise of weight, speed, puncture resistance, and longevity and the Schwalbe Marathon Racer is the best option for the average trike rider.

UTCustom Catrike Seat Extensions - We have had so many people tell us that they wish their Catrike seat could go more upright. Well, now you can! Our seat extensions let you adjust the seat back to a nearly vertical position. Hey, it's your trike right? You gotta be comfortable! And, yes, they are sold as a pair since you need both sides it would make no sense to sell just the right side (or just the left).
