ABX Express charges RM128 for 10 kg and every additional 1 kg is RM9 and the volumetric charges in kg 25 kg. That means , a package measuring 70cm x 30cm x 60xm will amount to 25 kgs. So that means an extra 15 kgs charges is added to the 10 kg charge. This means it cost RM263.00 to send the package to major towns in Sarawak. If it is minor towns, it is RM158.00 for 10 kg and additional RM10.00 for every extra 1 kg and this works out to RM308.00.

If I use the City Link quote dimension as mentioned, it will be 83 kgs. This means the normal bike parcel will cost RM128.00 plus another 73 kg x RM9.00 and the cost blew up to RM785.00 using ABX Express dry.gif

But packing the Brompton in the box, the former dimensions are enough.

Sounds like it will be expensive. Only special bikes would be worth shipping.

Thanks again Sifu!

About the shipping cost, i send my SUP board which is 21kg for rm96 only... with City-link.... Just a month ago.

Just go to MailBox, plenty of shipping company choice for you to consider. Let them kautim for you.

Guys, please enlighten me on 20" 451 Wheel set question... is the tire fix for 1 1/8 or can be larger?

Added a size table : Is this correct that it fit 1 3/8" tire as well?

It really depends on your inner rim width, ( scroll up to the top pages of the Sheldon page where you cut the table from.)

There is a table for matching tire width to rim width… just need to find it… its on the same page too… keep scrolling down…

Usually the inner rim width is written or stamp or engraved on the rim. If its not, measuring is trivial.

What do think about 1 1/8 tire compare to 1 3/8?

tyre?

1 1/8 lighter and easier to pedal. but i used panaracer, low rolling resistant tyre.

Thin tire roll faster is a myth from the 70's… so outdated…just like what they say soy oil is healthier than palm oil in the 80s and yet today all fast-food restaurant uses palm oil to replace soy oil because FDA say soy oil is dangerous hydrogenated oil while palm oil is healthy semi-saturated fat.yes FDA ban soy oil.
You would most likely to pump your 1-1/8 to 100psi or more to ensure the tire doesn't bottom out and cause snake bite punture. because of narrower tire, the shape of the contact patch will be elongated, high pressure is very bumpy. I pump my 1-3/8 to 75psi, because its around 22% wider and taller, can go with lower pressure without bottoming up, also, the patch is more rounded and bigger air volume (air cushion) hence it is much more comfortable. Yet still roll fast.
There are many forces acting on the tire, the 2 significant one which we can make a difference through tire selection are one the aforementioned friction force and deformation loss
Deformation force
You want supple tire (tire with thin side wall), i.e. less energy lost through tire deformation when conforming to irregular road surfaces not how narrow the tire that makes the tire fast. Eg. My becha tire is stiff and hard, the rolling resistance is high, replace it with a same size supple tire, the rolling resistance improvement is day and night. It just happened that wide tires are always stiffer than narrow one, so the misconception of narrow tire are easier to pedal and faster.
It's the friction patch size that determine how much friction(anti-rolling force). When you have high pressure, your contact patch is smaller, when you lower the tire pressure, your contact patch gets bigger…
So a fatter tire with wider rim , yes, rim width also affect air volume, more volume = more cushion = more comfy. Doesn't always man slower.
That also explains why really fast tires are very soft and therefore wear out a lot faster. And less punture resistance.

*PS supple tires are tire with really thin side wall, so thin it freak me out.

Folding bicycles are based on an adult's bike geometry, hence not really suitable for a child. You could modify the bike of course, but not ideal.

Bought a Garion 20" 7sp for my 9yr old boy last year.
Took him 2~3hr to learn how to ride. I used the "no pedal" video picked up from youtube by accident. The best part was he didn't even fall once! Happy daddy smile.gif

IMHO geometry isn't critical for kids having great fun cycling. Still remember how I learnt cycling on a oversized Hercules steel bicycle... can't even reach the pedals and handlebar while seating on the saddle tongue.gif

Foldie is fine for children, can always set em up for up right position a.k.a normal position. In fact Foldies has more adjustment than any other bicycle. The saddle can adjust low enough so that can avoid injury. On upright position, they can see where they are going…
