Finally i am curious and went to get a brompton. find the comparison between Fnhon 16", Tern 20" and Brompton 18"
Still Brompton win in term of folded size.

I am actively testing the bike out for pro and cons.

being a steel frame, and little elasto suspension the ride is comfortable.

handling i still feel FNhon is slightly better than brompton.

folds compact and can wheel around easily.

to travel with a folding bike by air, regardless of 20" 18" 16" the amount of work required to pack it, check it in, prepare it is almost the same. brompton may be slightly easier but not much. bottom line is you really have to plan your travel around your bike, to have thought that bike is another piece of accessories in your luggage is wrong.

been there done that...

both ways are quite evenly spreaded in terms on profile

http://www.mapmyride.com/kr/hanam-gyeonggi...route-155596999

however on a folding bike, you may takes a bit longer time, and with correct gearing i think folding is a capable climber, i climbed dragon back with my tern p24h, i think it climb better more tourque more low gear to play around with.

but with folding bike, you can actually bail out at some section by taking train.
hahahahaha

you see many people worried about not having MTB kind of gear on their foldie. for christ sake our wheel is 16 or 20 inches you don't actually need that kind of gear if you are fairly fit.
small wheel more torque.

for me the perfect gear for folding would be 52t front and 36t behind. if got double crank that would be good and perfect.

but in terms of good idea, my tern p24h would be very good. 44t front behond 11-32t, plus internal hub gear that can get really low ratio.

however implementation of the IHG is half hearted i would say, coming from the rear IGH gear cable routing design.

if they focus on it more, it would be damn fine.

half hearted only on p24H, must say that my 2 other bikes with sturmey arches was nicely executed.
you see on tern there is a lacking of pulley, plus slightly weird angle makes it not as smooth as say brompton or others, plus the shifter is not exactly smooth.
i guess rodalink must have received tons on complain on this particular model thats why they get rid of it at warehouse sale at rm300 to me. but at that price i would say it is the best bike i ever owned. barring some occasional gear skipping on the IGH. and a respectable weight of only 13kg. considering the rear wheel alone is more than 1.4kg.

QUOTE(desastar @ Jan 26 2018, 10:58 AM)

Since you have a p24 and running a 44t front plus a 32t rear, no wonder you are not missing the lower gears that others may be chasing for their foldies. Im running a 54t front on my Sram dual-drive and it is still low.

What's wrong with the IHG design? How else can the cable be located when the movement of the hub is horizontal? As it is, the cable or chain is already pulling at 90 degrees. Half-hearted? Lol

yes u r right, KHS is too heavy for my liking.
local bike shop sometimes they do not have expertise with IGH, but once you get the hang of it, it is as easy to tune as conventional bike as well. plus u r right, how much can they charge?

too many complain on tern p24h that's why even tern also gave up on the model. but i like it.

QUOTE(etigge @ Jan 26 2018, 10:56 AM)
52T/36T rear is also an mtb setup right? Double it with 36T chain ring, you get another 4 gear inches lower. That's why I opted for a single chain ring to simplify the set up. No front double chain ring is less work and maintenance. No extra cables to change later, no adjustments and a whole lot lighter and cheaper as well. No doubt though, the shifting won't be as crisp as a road bike setup. So far, for a foldie, the widest gear range are the KHS. They are triple chain ring and they are original but the whole setup becomes heavy. they have 27 speed and later a limited 30 speed models. Initially they were sold for over four thousand bucks and then slowly after changing distributors twice, it went down to almost 3K. I modded my Dahon Speed after them but nowadays, it is very, very, very hard to find triple road bike cranks.  rclxub.gif  Even if you find them, they are mostly Octalinks, I think that was the last of the triples manufactured by Shimano. The trend was shifting to double with bigger rear cogs and now even less chain ring and even bigger rear cogs.

The SRAM IGH dual drive with the 8 speed setup will give a range from 19 gear inches to almost 100 gear inches. That's why it was shodded on the Dahon Speed TR as a tourer. I don't think it was half hearted, it was meant to be that way. The Dahon MU also have a model with the same setup but it was not popular. Many other bikes in the west uses the same setup. Just that the LBS here don't really like to push them. The older generation LBS says 'mafan' while the newer generation don't really like un-conventional gear systems. Takes too much of their time, they say, " How much can I charge? " they always complain. That's why there's only a handful that do modifications. Modifications takes a lot of effort and time.

kakakkaak, 11t and the next cog after it is the most underutilised cog in any of my bike.

guys, don't over exert yourself when riding, i was on my morning ride at GCE saw one cyclist drop dead by the lane. I stopped get his driver's license from highway patrol, and post it on FB, take his phone try to call whoever that resembles family members and finally got to his wife. very healthy male 55 years old test riding his brand new s works fully equipped with power meter etc etc. after a long way finally his body was sent to sg buloh hospital for post mortem. i think he has got cardiac arrest. it didn't help when ambulance took like 30 mins to arrive. when i arrive i heard he was dead for 30 mins already.

Going over your Max heart rate in long run may damage your heart over a period of time.
It is especially dangerous for those who never exercise for decades suddenly decide to pump their heart out.

In saturday that case, I would assume it was a cardiac arrest or heart attack. We really don't know as the deceased seems to have time to stop and park the bike before collapsing. I would certainly think it is heart attack as usually cardiac arrest is sudden and unannounced.

Either way, for cardiac arrest, CPR has to be administer within 1-2 min to maximised the survival rate, AED has to be attached within the golden few minutes too, in this senario, survival chance is slim.

for heart attack, they may be slight better chance, blood thinner drugs- aspirin, etc etc. but if the blockage is severe, susah also la..
