i pretty much decided on a 305 wheelset, this will be my 6th bike. I have already got a tern 406 hence a 349 would not differ much in terms of experiences.
my priority is lightweight and portability.
I just got back from city cycling in paris, berlin and budapest. the worse thing about all these cycling is that the rental bike is min 20kg with 3 gears, so i figure even with a smallish 16" i can be par or the same with those bike.

I also get into a fight with the local bike shop because of inner tube size. I was looking for 20 inch (406) tubes and the shop gave me 2 tubes with 20" printed on it. I guess that the shop will know but when I got back, it was actually even bigger than 22 inch. I can't even use it on my wife's 451s. So, I took it back, thinking maybe if I can change them but the shop keeper's wife (women are terrible shop assistants) keep insisting that it is for 20 inch wheels. I said at least change to an 26 inch tube if you don't have but she adamantly says it is for 20 inch. I threw the tubes back to her and walked out.

Later I found out that the tubes are actually for wheelchairs. Although the biggest bike shop here in Taiping, I never patronise them anymore. Thing is , manufacturers have their own kind of listing like 20 inch x 1 3/8 inch and so forth, this actually makes the whole sizing perplexing until you really memorise what you want. At times, the shop keeper don't even know. The Kenda you mentioned must be the Kenda Kwest, that's the cheapest from Kenda Schwalbe makes them is probably for Bromptons and some mini velos. That's why so few models, namely the Duranos and Marathon Racers.

Anyway, 406 inner tubes can be used on 451s, need to stretch a bit. This makes it thinner and lighter in fact. But getting punctured while riding, you need to be patient.

Bicycle tire size specification is ridiculous! It took me many moons to finally figure out what my own tires are. With the same "20 in" there are only 3 different type with the same notation. The worst is "26 inch" it under Imperial alone it has 6~7 types on top of that there are Franch, Italy and Japan standard… and a few more types in each…

yes, all of them got their own standards..make it very confusing. and those zero knowledge shopkeepers don't help either.
for us is passion, for them is just another gig to get 2 meals on the table.

I puzzle why the 305 is call 16" 305 is only 12", unless you use 50mm or 2" tires… maybe the are referring to the mudguard size.
If you check your ruler, 20 in is 610mm, how to relate 406 and 451 to 20" is as mysterious as our formula for our petrol price.

305, 349 is the circumference of the rim in millimeters and likewise 451mm is the circumference of the rim for the 22 inch rims. This is also the same figure you use to configure your cyclo computer.

PS/ doesn't make sense either , huh? After reading even more stars

Not circumference. But The clincher catch diameter.
Circumframce of 451 is 451x3.142= definitely not 20inch, 406x3.142=not even close to 20inch…
1 inch = 25.4mm 451mm =17.75inch, 406mm=16inch…
So it's still doesn't make sense.

It's a mystery…

today i join rb group for some spin.



and this is the big boys game! lucky this group are not that fast. what didi i mean by "fast"? thiis group never exceeds 35kmh most of the time below 30kmh. lucky with those speed and route mostly flat, i can keep up.



many do wonder does my bike can fold?maybe this picture can clear the toughts



this bike i estimated weight around 18kg and its kind of heavy for rb. maybe double the weight of the rb. i really need to push extra effort to keep up with them..

ok lets calculate 700c wheel dimension

700c, also a mystery…
Anything with an alphabet as last digit are French, 650B, 650A, 650C, by definition, A is narrowest, C is widest, but in the market tires having 650c printed on it is always the smallest (17c-19c) and 650A only comes in 1-3/8" width, I know because I need a pair of 650A aka EA3 AKA standard British 3 speed aka 26"x1-3/8" On my fake basikal tua. No this is not the same as MTB 26er which is another mystery…
Anyway, 700c is 622, to get to 700, you need tires at least 39mm tall… got or not?
More mystery to solve before we can get to the Bigfoot mystery…
I have strong believe 700c refer to the mudguard size, not the tire size

Hello.
I am newbie in folding bike world and hook up with the foldie when I saw one.
I am thinking of looking for a foldie for myself but still not sure what are the thing that I should aware of. (still clueless of the terminology).
Anyway, I would say that my budget is about RM1K, looking for touring/long distance type, manageable going uphill and downhill. The 20" kinda catch my attention.
Any suggestion on the brand?
Thank you in advance.

hunt for a used dahon chromoly framed bike. really comfy for touring/long distance travelling. maybe need to increase your budget a bit. but it'll be well worth it.

There's a korean used item store nearby Ampang selling a Dahon D7 with dirt cheap price.
I had check and most part is alright, Might only need to replace chain and cassette, maybe tire as well.

It's a super good deal from what i see. Been tempted to get but i have too many bikes at home

WTA what is the best taobao agent if I want to buy fnhon from china?

i use EZBUY

Ic, do u come accross sgshop?

And what about malaysia custom, do I have to pay any tax when the item arrived at malaysia?

have u use ezbuy to buy fnhon?

I see. Which dahon do you suggest?
I also saw some people use Java or Trinx but not sure about which. Thus asking otai here for info. Hehe.

Thank you for the info as I do not mind for a used one but unfortunately I am in Sarawak.

same here, only i am at sabah

Java / Trinx are good enough for fresh blood. It can handle mid-level ride but pls look for 8speeds and above. Easy for u to upgrade later on.

However, I do think u might wanna increase ur budget a lil bit. Must consider cost for other cycling gears such as blinker, helmet, spare tyre etc.

Pls check the hinges before purchase and ask the bike shop to tune ur bike first upon confirmation.
