This HP Velotechnik recumbent trike seat is about as close to new as you can get without being officially new. It was briefly used on a demonstration-model recumbent trike at Amlings Cycle & Fitness (RIP). Please closely eyeball the pictures: the only sign that the seat is not new is the evidence of black paint being scraped off the rear mounting brackets. The cushion and frame are otherwise pristine. I have placed yardsticks across the seat to give you some idea of the dimensions, and I have tried to show the mounting brackets on the back of the seat. To the best of my knowledge, the seat can be used on a variety of HP Velo recumbent trikes (and bikes too.) It might be possible to adapt the seat to another brand of recumbent if you are willing to do some MacGyver-style alteration. It is very light weight, and is of high quality, like HP Velo cycling gear generally. Thanks for your attention, stay safe, and happy riding.
