Spongy Wonder Bicycle Seats

Enjoying my new Spongy Wonder bike seat - BIG TIME! Admittedly, it took 5 or 6 rides to find that optimal combination of seat height, seat width, seat angle, and handlebar height. But once I found that "sweet spot".....YOWZA! My wife gets up in the morning and I'm already GONE, sometimes for hours. Love this bike seats. I like to call it "Perineum Freedom". I'm scheduled to meet with my urologist next month and I'm going to give him one of those business cards you gave me.....more than one if he wants. Thanks to my new saddle I'm now able to continue doing one of my favourite pastimes. AWESOME! Thank you Jeff.

And best regards, Joseph LeBlanc

“Human beings are not designed to sit on something that resembles a rounded two-by-four.” - Jeff Dixon, Inventor


The Spongy Wonder is 3 inches shorter than most conventional bicycle seats. The rider cannot even see the front end when sitting on it. The front end is not in the way and neither does it present any issues.

"While 'horned or nosed' (bicycle seats with a horn or nose) bicycle saddles with troughs, grooves, or center cut-outs may feel better because the internal penis fits into this area, the nerve and blood supplies to the penis lie along the sides of the internal penis, therefore the pressure on these key structures actually increases along the edges of the trough restricting blood flow. Grooved, cutout designs may not be better, and may be worse, than a solid saddle nosed seat." Dr. Steve Schrader of NIOSH

Even more happy thoughts from SW Bicycle Seat Riders

Seeing injuries from bicycle seats fairly often in my internal medicine practice, I was happy to discover the Spongy Wonder Bicycle Seat. I immediately bought one for my own bicycle, and was quite gratified to see how comfortable it was, while still able to maintain good control of my bike. I've had mine for a year now, and have yet to put on the replacement cushions! If you're a rider, old or young, male or female, you need one of these bicycle seats.

The Spongy Wonder Bicycle Seat is great and the best of the noseless, perineal sparing Bicycle seats that I've tried. I'm going to the site to order another one for my other upright bike.
