Folding seat post

In our opinion, correctly adjusting the saddle position is absolutely basic to ergonomically correct riding. With a badly adjusted saddle, at the very least you use more energy – in the worst case, health problems, for instance, damage to the knees may be the result.

With a BERNDS you don't need to adjust the saddle height every time you unfold it, because its unique folding mechanism means that the saddle is automatically in the right position chosen by you. 

Up to the present day, there is only one folding bike that can do that - the BERNDS.

We have taken a lot of trouble to give you this benefit: 

the hinge is complex but precisely manufactured so that it moves easily and works perfectly. 

Just like the handlebar stem, the upper seatpost is a standard size so that very different lengths and saddle offsets can be used. 

On the plus side again: our hinge seals the seat pillar completely to water seeping in. Since there is no water entering from above, the bottom bracket does not need to be open at the bottom - unlike other bikes. As a result, even after years of intensive use, you can change the bottom bracket on a BERNDS without too much effort.
