What dahon is that?
Boardwalk D8 has one lever for folding and one lever to adjust the height.
I open the height adjuster, adjust it nicely n tighten the nut before locking.

corrected your youtube link. you dont have to copy paste the whole url, just copy paste those after "="

in your case,

Sometimes they do!  But you will feel it if it does. If it does just adjust it back. Dahon handlepost do get loosen especially after hard bumps but not in all bikes though. For this you need a 6mm wrench and turn the small little nut a little bit (only if it is loose). The nut is the one inside the handlepost and you can see it after you fold the handlebar, there's a small nylon piece and a nut there. Don't touch it if there's nothing wrong though

Finally my Dahon frame arrived!    Anyone interested in a Dahon Speed P27    Some old parts but mainly new parts. At last I can dispose off all the parts in one go!

If the shifter mechanism is out, you can actually take out the emergency bike tool (it's better to have one in your pouch) and then loosen the RD allen nut and adjust to an average gear (somewhere in between) and then tighten the cable clamping allen nut. Although it runs on single speed, at least it's not on the highest gear! You are the first person that I encountered with shifter malfunction. Another way is (if your bike tool have a chain breaker function), to break the chain and take the chain out of the RD cage and adjust the chain length to the middle cogs of the cassette and then rejoin the chain back when you change or repaired the shifters. 

Someone should start a bike workshop for beginners. Some I know can't even repair a puncture!

-to get more rigid feel
-to change handlebar type, like straight one to dropbar

For twist shifter, right hand is short n left hand is longer

Billy shop did not have ergon grip for twist shifter before. I asked him oredi.

I gonna get one

bole refund kot if he still have other stock as long as u did not open the package

still can use but u have to cut the right hand side shorter to accommodate the shifter

for twist shifter, buy Ergon gripRohloff-Nexus

but if you cut then how to grip and shift? 

i guess i need to return it .. the is there any replicas which similar to this Ergon grip? Ergon GP2 price is almost rm200   yikess...
