I know I already posted - changing positon

Hi,
I own Tern C7.
With the current setup came from manufacture.
I want to leaning forward.

I want to know if there are any other options other than the picture I added?
Any kind of stem changing of stem is "tied" with a 'T' handlebar tube?
I would need to replace the handlbar too?
Wihch diameter to all of the parts?

Please help me

Read this blog. Look at all the pictures. Read about Tern and Tern/Dahon stems.

Go to the Tern forum and do the same there.

Google search "changing stem on Tern bike" or something similar.

Hi,
Quote:
Standard handlepost clamp seen on most Dahon bikes. This clamp opens up fully, so you can also install a bullhorn bar or a drop bar directly in the clamp.
But I dont want a Road handlebar.

Belive me that I already read.

One more thing: Although I read some stuff - I find it really hard as it hard for me bc's of concentration difficulties.

So if anyone here can share with me the info it would be amazing.

Thank you very much!

Once you get that piece , any 1" center sleeve (For the width of those 2 clamps) will do.

Must say that I dont remeber that kind of treatment. @fietsbob and @reppans Why behave in such a cynical way? @badmother - thank you for the good intention.

Is there anyone here that willing to help here?
Is there any other options other than combination of:
'T' Handlebar + dual-adjustable stem
???

Links:
'T' Handlebar
Dual adjustable stem

Thank you very much

I think part of the problem is that you are giving us wery little information. It is like asking "What shoes should I buy and where should I buy them?".

I understand the shipping problem but since you say nothing about where you live we can not help you with suggestions where you should shop from. Most of the time shipping prices from Asia is cheaper than shipping from USA and western Europe but it depends where you are shipping to.

Are you a man or a woman?

Short or tall?

Do you want the bars further forwards only or up or down in the same operation?

Is weight of the bike important?

Do you want an adjustable stem (up and down adjustment)?

Do you want to do the job yourself or ask a bike shop or a friend to do it?

Is there no bike shop in your area that can help you?

I have been looking trough old posts and googeling looking for pictures. I have a problem with my computer so I can not post links. I have no time to fix my computer just now (could maybe dig out an old computer) so it is difficult to help.

It is possible to use your old stem and just buy some more items to fix your problem.

There is also several stem options, stems going almost straight up from the bike and stems leaning forwards quite a bit. You could maybe solve your problem by buying just one new stem that is leaning forwards much more than your present stem is.

Also you could keep your current stem and buy the "aber hallo" extender only. No need for a new T stem.

Ther is one more option. Since I can not post a link you need to Google : Tern Andros stem extender or Dahon Andros stem extender.
You can also look for pictures of bikes with that extender.

Maybe it is possible to buy cheaper copys of the two andros options. You may want to e-mail or call one of the shops you want to buy from since they could have copys that have different names.

I do not own a Tern. I can not go to a shop and look at one, I can only use the internet to learn about them. I know there can be different parts on same bike in different part of the world so I can not be sure without knowing where you live (or where the bike is bougt). A Tern C7 bought in Europe could be differen from a Tern C7 bought in USA or Asia.

Yes, there are other options than what you posted a picture of but the one you posted is a good solution if it is long enough for your need.

I need to see a picture of your bike or a similar bike to yours but I would say you can use your old stem for this modification. No need for T stem I think.

You can use your old handlebar.

Go to YouTube and search for: Andros stem install

Also search for (You Tube): Brompton S2L: Raise the (handle) bar- sporty with upright riding position - best of both worlds!

The second film is a different bike, different problem, different handlebar but same system. You can decide if you want the handlebar to go up, down, forwards or backwards. You decide. In this film they use "aber hallo" stem extender. You can use a different name same look item, like Litepro.

Wahooo!
Could wished to such an amazing answer!

I will try to answer as much as all of your questions:
1. I want it leaning forward - but not as a road bicycle.
I would say - not too high to low position - maybe in-between mtb to road.
I cant say/think what is the ideal for me.

2. I'm short male - 5.25-5.245 feet

3. Weight: As right now it a bit heavy(12.5 kg) - I dont want adding too much.

4. Adjustable stem: If I able to set the right position with regular I wont need it.
But guess it important?

5. I have many bike shops around - a mechanic will do it.
**As I dont know nothing.

6. I dont mind staying with the current stem as long as the new set-up will solve the riding position.
I just want to leaning forwards - a bit...not as a road cycle.
Both the Tern Andros stem extender OR SATORI Adjustable Stem ABERHALLO OR Dahon Andros stem extender are a good option (after watching on youtube)
BUT >>> I could recognized the 'T' handlebar there...which means I do need to replace it.

7. I could not figure out HOW COME it possible just using stem such as the Adjustable stem without REPLACING the old handlebar (to a 'T' type)?

8. Sorry - but I dont have a photo with me and today I did not took it with me to office)
I can only say that I own the 2013-2014 (not the 2016).
I live In Israel.

Summarize: It is really possible solving cycling position only by replacing to stem such as SATORI/ABER HALLO design ??? Without changing to 'T' handlebar?

Thank again (an a lot!)

One more thing.

If you need quick fold like the bike is now buy the more expensive like Andros.

If a slow fold (using one tool) is ok or if a small fold is not important the cheaper Aber Hallo (or similar from other factory) is ok.

6. About using your current stem and not a T stem. It is possible, no problem to make it fit but:

I kept searching for old posts and found a Bikeforums post about this. You need to take som time to look at this post, there are a lot of pictures. search for: Aber Hallo or Litepro Stem Ekstender?

In that thread they say that maybe the quick release top (like you have on your bike) is not strong enough in the long run to hold the handlebar.

I find that to be a bit strange becouse if it can hold a handlebar it can aso hold the handlebar extender unless you are an extremely strong rider and pull on the handlebar a lot.

I have seen no warnings from peopel selling the extenders not to use them with quick release.

Also you can buy a new top for the adjustable handlebar and I would think also a top with two bolts instead of a quick release if you are worryed about strenght.

In the BF thread about Aber Hallo and Litepro there are other options discussed also. You can cut of the top of the handlebar and use an adjustable ahead or quill stem that may be in the shop already so no need to buy online.

I think you should first choose a shop (a independed bikeshop, not a chain store) and talk with them about what they can do.

Print out the thread I mentioned (or bring a computer to the shop) and ask in 2-3 shops what they would suggest.

You can also e.mail them with a link.

Yes - I prefer staying with the quick fold. Unless it not a big difference.
So I dont mind to stay with it.
I read the aber hallo litepro stem extender: There are few methods there.

Such as:
This
Similar as above
Folding Bike Modification - Aviation Aluminum Double Stem Kit
Double stem mounted on a T shape handle post
This (how is it possible w/o T handlebar??)
DAHON ANDROS stem (but again, T handlebar is needed)
ABER HALLO STEM >> It looks like this is the only one that able to installed w/o T handlebar?

I dont see anything from the options that does not include replacing main parts...
Correct me if I was wrong.
After I read EVERYTHING and feel quiet confused...

Part of the problem is that the bike (all folders) is made exactely the way it is is to make it possible to fold it small. When you start changing things a small change can make a HUGE difference- in folded size and in the time it takes to fold the bike, plus the bike can refuse to stay closed when foldes so it can start opening up when you carry it. It can be more comfortable to ride yes, but impossible to fold properly.

Changing out parts is expensive, buying the right bike when you buy is cheaper...

In the last BF thread I mentioned they suggest to look for a stem that is leaning more forwards than the regular ones. They say most stems are leaning 12 degrees (if i remember right) and that you should look for one that is leaning forwards 17 degrees. I suggest you e-mail the C H White shop you linked to and ask. Tell them what bike you have and what you are looking for. 17 degree stem only. No other parts.

you seem to miss the simple mechanic logic (it happens when people take computer classes, instead of shop)

by putting a tube the same size as a handlebar in place of your handle bar , in the existing steering mast,

then putting something like the various things you found to make your 9th post,
gripping that and then put your handlebar in it.. the double clamp pieces join those tubular pieces..

Thor Does not make the Aber Hallo, he found the manufacturer of it and has a dealer's account with that supplier.



So you don't need to buy a T steering Mast. you make its function,
with the substitute section of aluminum tubing*, or solid aluminum bar, you seek out.

You are finding out Folding bikes are not made in various sizes ,
its expensive enough to design and make just one product in one size.

* you can buy a simple seat post of the right diameter, and cut it up ..

I went to the impoeter shop.
They saw the "Adjustable Double Stem" (TranzX) sell on Ali and told me that the product would be just fine and even offered to come and they will install it.
I added the setup as they was explain me.

What is your opinion?

Perhaps barends if you want a more streched out position. Perhaps they too can be quick released.

I do want to more streched - how much? some like between MTB to ROAD.
How much streched? I marked my "desired" one.

Regarding: "Perhaps they too can be quick released"
On daily use I do not fold the handlebar. Only the frame.

Hope it helps...
Is there a reason why this stem would work with the bike?

On my 20th response I told what the bike shop told me (that the TranzX would work).

Sorry, I dont understand whether it cynical or not.
You must understand that although I write&speaks gr8 = I found it hard 2 understand these kind of responses.
And I must say that I appreciat anyone here who trying to help.

@fietsbob
You asked a pic's of the bike.
So here are they.

All of the correspondense could be much shorted if we could discuss stright to the point.
What do I mean?
1. I wrote which positon I looking for.
2. I mentioned what the mechanic of the importar shop told me.
** I cannot say in 100% that I sure about his opinion.

Thank you
