Dahon Ios D9 extend post
 

Hello fellow cyclists
I really need your advice on an issue that I encounter.

I recently bought a Dahon Ios D9 folding bike. I really do like the bike, its features and the overall feeling and performance.

However, the only disadvantage is the short length of the handlebar post. It is a solid piece of specific length, not adjustable, relatively short, and there is no stem option (at least to my knowledge,) because it is a T-bar. Additionally, I need to have my seat post high enough in order to pedal correctly and efficiently. Hence, I am riding with my body bowed forward to some degree which hurts my lower spine.

I know some cyclists like to bend forward all the way when riding but for me this is an uncomfortable position. I already have done some research on my own with very poor results. It is a challenging matter to my opinion. Thank you in advance for your enlightenment!

I've ridden a Dahon Mariner (similar geometry AFAIK) & I couldn't get a good handlebar position (height OK but reach too short). Dahons seem to be designed for short rides. Custom-made stem might work but would probably cost ~$400.

Thank you all so much! I think I ended up on my decision. I am going to use a riser handlebar. My local bike store has one that makes a 4”+ difference which is perfect. It’s going to make my Dahon a little bit like a BMX but I don’t mind. it might even look more cool and I’ll try to get used to it.

Problem solved, with persistence, research, and experimentation. Unfortunately, the original Dahon T-bar double stem was not compatible with the clamp diameter of any common rise handlebars. Nevertheless, I found online a special stem compatible with those rare Dahon T-bar posts. This stem not only gave me 2-3 inches extra height by itself, but also made it possible to use a regular riser handlebar which offers me another 3 inches, ending up with a 5-6 inches rise which feels reeeealy comfortable! Look at the pictures below.

By the way I have an older folding Dahon D-7 that I want to sell online. Could you guys recommend me any website where a can sell it? Thank you so much! Be safe, healthy and happy!!!

Happy Independence Day !!!
