Picture shows Narrow Medium and Wide
All have memory foam and are super comfortable.
They are unisex but we recommend the Medium or Large for Ladies. ( Simply because their sitbones are wider apart )

All are a great upgrade to OEM supplied seats on any bicycle.

All are designed with a more upright seating position.

The new standard in comfort ? Kush Plus saddles have memory foam. This is the wide version. Super comfy but not as wide to chafe your thighs.

Medium, comfort for your next bike tour

Narrow. Not as narrow as the Tour de France saddles and so much more comfort. Great for longer rides and simply to upgrade from your regular saddle.

Great sportive seat with just enough Gel to make it comfy. Underside has cutoffs in the shell to distribute loads better and give comfort.
Nice seat

You lost your seatpost ? somebody stole it ? We offer the regular Dahon Seatpost at a value price to you

33.9 fits Dahon Tern and many others.

558 grams, 23 inch long ( 580 mm ) from bottom to seat rails.

Min insertion mark at 4 inches ( 100 mm )
Max mark at 14 inches or 360 mm
The Max mark means that if the seatpost is any lower it will hang below the Crankset and poses a risk that you catch something. If your kids need a shorter seatpost we suggest to cut a portion off.

How many times have you knelt on the ground and cursed under your breath as you've tried to inflate a tire with a small mini pump? If you're like us, it's been too many times to count. The PostPump is an ingenious product that integrates a powerful floor pump with a seat post. The pump is always ready to go, hidden from the elements, thieves, and your own forgetfulness. To use the pump all you do is remove the seat post from the frame, attach the valve, flip out the foot peg, and start pumping using the saddle as the handle. Go over 100psi in less than half the strokes of the best mini pumps. Brilliant! Suitable for all models 33.9 mm seat posts. 718 grams, 580 mm long. Saddle NOT included
