Note that the Zee RD comes in DH and FR spec. FR is the one that takes the 11-36T cogset. If you want to splurge and have excess funds, there is also a similar, higher spec Saint RD. You may find this thread helpful.

I have not changed beyond 1.5" (only swapped before to 1.25" Kendas)
But I did speak with the local distro and was told the widest will be 1.75" with the fenders removed.

However, since the stock bike has a rear fender with a coaster wheel to roll the bike along when folded, it means the bike would need the rear rack if the rear fender is to be removed to serve the same function.

Thanks a lot Abu. Your thread link is very helpful, the before and after pictures. I will go that way. Thanks again Abu and Pinholecam!

My present RD is a long cage.

Good luck. Yeah, that RD looks too long and low. That Birdy looks good. Report back (on that other thread or here) with images once the deed is done.

On carrying luggage

While I wrote earlier that the bike handling is unaffected with the carrying of things on the front and rear, there are 2 issues that I found with my way of carrying the stuff.

1. The Tern luggage truss can loosen over time with the way its positioned trussed out from the front mounting point if the luggage is heavy.
This can be due to me not using split washers too, so I've switched to them once I got back.
Not too big a deal if one is carrying lighter stuff like clothing but I had all my camera stuff on the Ortlieb bag in the front.
Its good to do a pre-ride check that the mounting screws are tight before setting off anyway.

2. The rear rack, being low, does give heel strike problems if the rear luggage juts out wider.
This is easily solved by making sure the luggage is set clear of the heel strike location.
Anyone considering rear panniers should take note and try out systems that cater for small wheeled bikes with heel strike clearance.


Other than these, I think the bike is no problem with what I carried.

more updates..

Balerang 6 Bridges Ride


Another ride coverage with the Tyrell IVE, this time to cover the Balerang 6 Bridges in nearby Batam.
The ride is certainly undulating most of the way and running a 1x10 with wide range cassette has become what I believe to be one of the best ways of gearing up a foldable bike.

No traffic lights where the legs get a rest, long stretches followed by long inclines, and instead of looking for the highest 11T cog, the lower cogs play an important role of riding at a good pace w/o 'blowing up' or building excessive fatigue that prevents riding the next day.

Running 1x10 (or 1x11) simplifies things with just a shift up/down of the gearing needed.
No running up the slope halfway and feeling that large drop in gearing one gets when shifting from large chainring to the smaller one.

At a point, the bike reached 60kph on the downslope and I do think it handled fairly well at this speed with its long wheel base (despite the 18" wheels and small fold).

Singapore to Malacca
About 245km over 2 days, with the Tyrell IVE.

Only 2 foldies in the ride of 55 cyclists.
The other being a nice looking Tyrell Fx.

Hung on to the tail bits of the first group of riders (ie. faster).

20170218-IMGP5265 by jenkwang, on Flickr

20170218-IMGP5286 by jenkwang, on Flickr


Further thoughts :
1. In a touring group ride, the regular need to stop to re-group/refuel/rest does make the speed advantage of road bikes less apparent.
At most, the faster riders open a 3-5min gap between me and them over 20-30km, then they have to stop, and I re-join.
So basically - use the folder with confidence.

2. Long flat stretches do give road bikes the advantage. The overall efficiency, more aero position, do come into play more than more hilly rides (like the Balerang one mentioned above), there the playing field is more even (only weight comes into play)

3. I wish the IVE can take aero or drop bars more easily w/o complicating the fold. So many instances where a more aero/powerful riding position would be beneficial for closing gaps in the riders or for long flat stretches.

Nice. And quite fitting. From (the former Straits Settlement of) Singapore to (the former Straits Settlement of) Malacca.

To complete the troika, you should press on to Penang. One day I hope to do Penang to Southern Thailand, and the southern tail of Myanmar.

Phuket to Krabi - 2 Century Rides

Updates again


Its always good to get the bike on the road and subject it to use conditions one will see on a longer ride.
This time being Phuket to Krabi (and back) with the folks from MBG (My Bike Group).
MBG is a group of like minded folks who are very enthusiastic about overseas riding and often organize local as well as overseas rides.



The plan is simple.
168km from Phuket to Krabi, R&R for a day in idyllic Krabi and then the 168km back to Phuket.
Exotic overseas location, nice food.... can't get much nice for a short trip.



A nice view at the end of a ride is always welcome by jenkwang, on Flickr

Looks like a super nice bike. Mini Velo, yet folding. I like the traditional triangle approach. What is the measurement on the wheelbase length?

This is a really nice bike in use.
Stiff, yet the selection of wider tires and the very hard rear elastomer and steel frame gives a comfortable ride.

Wheelbase is 1058mm

Phuket to Krabi


20170715-IMGP5985 by jenkwang, on Flickr

One advantage that a folding bike (that can be rolled around) gives is that it can go into shops, malls, hotels w/o problems.
No leaving the bike leading against the glass wall of the cafe on the outside, while one goes in to get a meal/drink.
All the while having to keep an eye on the bike against anyone who might make a swipe for the bike.


The route between Phuket to Krabi is relatively easy.
About 1.2km of climbs over 168km.
The IVE with the 11-36T and 18" wheels is certainly enough gears to cover the ride.

Do you have to take off all the touring gear each time you want to fold and go into a restaurant?

It depends on the type of tour and the packing.

So many cases, I have already checked into the accommodation and left most of my things there, so there's nothing much on the bike (so no need to unload the bike before folding)

Then there are light tours where I am only using the Ortlieb bag on the front ( so no need to unload the bike before folding)

Next will be a loaded rear rack, but having everything in one bag, so thats not a big deal to unload too.

I have a few straps on my rear rack. (Bungies made from old inner tubes)
Some hold down the less taken down stuff (eg. stuff I won't use till the end of the day)
Other straps hold down the stuff I take off the bike often (eg. tripod; extra water container).
So there is no need to shuffle thru all strapping just to take the regularly accessed stuff.

Day 1


20170715-IMGP5964 by jenkwang, on Flickr

Day one started off at about 7.30am after breakfast.

Since it was a supported ride, the clothing bag was left on the van.
Not wanting to wait too long in the event or rain or punctures (and in the spirit of self sufficiency), I carried the spares and a rain cape on the bike.
A tripod for any photo ops or selfies if I had the chance.


Rain is almost a sure thing for such long rides, so water proofing what is carried is essential.
This can be really simple though, like a water proof 10L bag and plastic bags (for the wallet/phone/camera/passport).
"By right" Thai law requires the traveler to carry the passport with him at all times, though one can also just do with a photocopy.



20170714-IMGP5911 by jenkwang, on Flickr
Almost every stall seems to be able to whip up very good Thai fried rice, almost like its a qualifier for opening a food stall.

I wonder why this Tyrrell Ive does not have a version with internal gear hub, or if it could be possible to make the upgrade.

It would not be hard to change it to one, but I guess its just what the makers decided to spec the bike on.

Thanks for your answer, pinholecam.

I see you are very enthusiastic about the Tyrrell Ive...

I am the owner of a Tern Link P9 for 5 years now and I am very satisfied on how fast and sturdy it is, but it's time for a change now.

I am looking for something better for the city, a bit lighter, more compact when folded and ideally with an internal gear hub.

I tried a Birdy some months ago, while I was at K.L., but I didn't feel it as good a ride as with my Tern, plus the bike is not so light.

Still, I think I have to go from 20" to 18" (I am reluctant to go down to 16" and specially to Brompton), so I have a dilemma:

* Tyrrell Ive, if only it had an internal gear hub.

* Chedech, if it had some system like a rear rack to carry some luggage.

What do you think? Specially, if you know the Tern Link P9 and can make a comparison with your Tyrrell Ive I would really appreciate.

The thing about the Dahon/Tern fold bikes is that they are pretty utilitarian (in a good sense).
They have a wide range of add ons to choose from (ie. racks, mounts, accessories) , work fine.
The 406" wheels on most of them are a good middle ground wrt size of fold, speed and tire options.
They even roll well folded once one ties it up with a velcro strap.

The 16" vs 18" vs 406 vs 451 is always this conflict between fold size and a bit more speed.
IMO, 18" is the better compromise between 16" and 20" for fold size, a bit more comfort with wider tires and speed.

So its still back to what you ultimately value/need for a new bike.
Best fold size (ie. 16" Brompton or 14" Crius Smart 3.0)
In-between (18" Bridy or Tyrell IVE)
Better speed (406/451 wheel folder)


Whats the reason that you prefer the IGH?
I have a Crius Smart 3.0 (3 spd Shimano IGH) and there certainly is a bit more drag on it than a deraileur system.
As you probably know too, over here in South East Asia, IGH are not popular at all and support will be poor/none.
It will be hard to get hold of a 8sp IGH here and they will have to be built up (no off the shelf IGH whee).
You can try Taobao though where I've seen wheels with IGH setups.

So, do you mean IGH gives a poorer experience on pedaling than a dérailleur?

I am a bit tired of the cassette, it easily gets disadjusted; it could also be useful IGH in the city to be able to change gear as you are stopped.

It would mean a heavier bycicle, though.

What cogset and derailleur are you using? Contemporary Shimano transmissions are remarkably consistent and reliable. They shift crisply and accurately time and time again. I would just set up an IVE with a Shimano Zee RD, 11-36T cogset (SLX HG81 or XT M771), and quality Zee/SLX/XT shifters.

>> For my case, yes.
I was rather keen about getting a bike with the IGH, but after using it, I think I prefer the derailleur system.
This of course is in the context of my ride preference and environment.
So YMMV


I am a bit tired of the cassette, it easily gets disadjusted; it could also be useful IGH in the city to be able to change gear as you are stopped.
>> You will probably need to find a store that can help you with the RD tuning every now and then, or learn it via Youtube.
I've never needed to shift at stopping, but I live in a rather flat place.


Do consider your options.
Like what Abu_M said above a 1x system (Saint/Dee with the 11-36t cassette) is nice option.
