How to set up a folder?

Looking for info on how to set up a folder for long rides. I posted this in the Bike Fit Forum but thought I would get more specific info here. My folder is a very light weight Dahon. Type of info I'm looking is seat height and fore/aff and handle bar height. Anything that would make it an all day rider if that's what I want to do.

How do you set up a regular bike? to suit your body and preferences..

I put Ergon Grips on my Brompton M3L, fitted a saddle I liked , you can change the pedals to something you may prefer /

those are the 3 contact points . adjusted the saddle reach to the bars, distance.


other than that.. long rides are just more hours spent in the saddle turning the pedals .

if uncomfortable after a couple hours get off the bike, stop in and buy a snack , pick up a brewski, take a break,
then go another few hours ..

seat height? like any bike.. pull up post till when your heel is on the pedal the knee is straight,
so ball of the foot it's a bit less than fully extended.

once there , note where the side of the saddle touches your hip standing along side the bike ,
since every time you fold the bike you drop the seat.


DaHon owners may have some things they like to do .. parts to buy and all that ..

Hi,

All folders are fundamentally not suited to any extreme of bike riding.
IMO they don't do long distance and are not built to do that efficiently.

rgds, sreten.

My road bike just utterly creams the folder over long distances.
(Wheel size being an issue, bigger the better is always true.)

Oh, nonsense; I've done long loaded tours bike camping tours on my BF; some other folders are very fast. Not all folders are suited for touring, or for fast riding, but certainly many are.

Thanks for all replies. My folder is a very light Dahon Helios SL w/8 speed cassett. The handle bar stim is fixed and I'm considering how to modify it to add a stim if anyone has ever done this. Maybe an adjustable stim and road type turn down handlebars. Also what would be a good way to add a small hill climbing touring front chainring and shifter. What brifters would work with this. I posted this here as some may have upgraded their folders in a similar manner. Whaat other mods should I consider.

Check out Thorusa web site there is a picture under technical of a drop bar Helios Sl conversion. Thor could advise you how to add a front chain ring.. I added a front chain ring to my MU P8 and made it a P16. I have toured extensively with this set up.

You're not familiar with critical thought, are you? Just passing off opinion as fact.

Hi,

Anything compromised for purpose is going to be limited.

rgds, sreten.

I like my folder, I like riding it, I accept its limitations.

Are you sure you don't want to qualify that, or do you do want to stick with it as is?

You guys are funny today!

I suspect the question has, at its heart, an assumption that a non-folding bike can fit better than a folding one. So the key to folding bike set up will be the way his non folding bike is set up.

With folding bikes we have to compromise between the ride and the fold. The ones that fold the best (strida, brompton) do not necessarily ride all that well (yes, i know Brompton riders of a certain size will object), and the ones that ride well (swift) don't fold that well. Even if you do find a good compromise (I am very happy with my Downtube 8H) you must still make further comprises: a drop bar would give more hand positions but would severely impact the fold).

The best compromise is to figure out what hand position you use the most on your favorite non-folding bike, and replicate the relative hand/seat/pedal positions on your folding bike.

Well, getting back to the original post, Tony N is asking for advice on how to set-up his Dahon Helios SL for all day riding. My thoughts:

Sreten - I don't think putting larger wheels on the bike is realistic. However, you appear to be knowledgable so perhaps you can give him other suggestions.

One question Tony N - by all day riding do you mean covering long distances or meandering a bit - taking breaks, sight seeing? If you want to eat up miles you may want to try to achieve a more aerodynamic position. If puttering about, maybe being upright is more comfortable for you. I suppose you will answer that you want to do both. Think about what position will be most comfortable for you for a full day of riding - most people have a pretty good idea of what works best for them - some like drop bars, some can't stand them.

It looks like you have been given good advise to check out Thorusa.
