You mean that thing at the back of the frame is not the suspension block?  Silly not to include one as the position is already there!

Nice bike though.  Thanks for the rundown.

When you have a rubber block there, there's a possibility that it might wobble in the long run as many has demonstrated under poor maintenance. Like those 'B' copies, the MT from Flamigo, it wobbles even when new. KHS foldies on the other hand has a rubber block embedded inside the steel tube and this helps but the travel is just minimal. Unless you machine the pivots precisionly with sealed bearings embedded, many will have movements. That's why they prefer not to have suspension there. Even Dahon Curl omitted the rubber block altogether by going for a snapped tight V-joint which totally clasp the joint solidly without movement. They also patented the blardy joint! rclxub.gif

If you take a 'B' unfolded and you lift up the rear wheels, you will feel the movement. That's what Tyrell wanted to avoid , probably and also Dahon Curl. A lot of care and maintenance is needed as this point as movements without grease will equate to wear and tear faster.

i would buy this dahon curl if it is below 5k

I am still waiting rclxub.gif They launched once but failed because it was too expensive. They used the highly advanced internal geared crank called Schlumpf system and internal gearings at the rear. This makes the bike hyper expensive. They retracted the launch and went back to the drawing boards. Now they have announced that the re-launching is in Spring this year. Keeping my finger crossed. I too, budget about 5K too for the bike.

I am not worried about the 3 speed of the bike. As long as the rear hubs width is the standard 135mm as opposed to Brompton's 128mm , it's fine. I can fit in the Shimano Alfine 11 speed or the Rohloff 14 speed into it without modifications to the frame. Also it is a full 18 inch bike, bigger than a B, lighter than a B, folds smaller than a B and most important, modificatiosn are possible. thumbup.gif

But sifu, by the time you add Rohloff or Alfine, it is no longer $5k and then the weight goes up.

Actually I wrote to Dahon to sell me 2 Curl's frame but no response from them...hahahaa tongue.gif My main criteria is the wide range of gears and a Rohloff's 14 speed is equivalent to a 3 x 9 speed and the Alfine slightly less. The Alfine is about 1.5K here with the shifters and chain tensioner and the Rohloff about 3K. That adds up to 8K IF....that's a big IF , the Curl is going for 5K. It still beats the price of a Brompton which is almost 13K if I want to use a Rohloff! rclxub.gif The rear triangle itself cost almost 3K and plus the Rohloff another 3K and plus the cost of the Brompton itself that's too much already.

The Bromptons are manufacture in such a way to forbid modifications unless done by them. That's selfish and also they wanted it for a main purpose only, short commuting rides. Off course there are exceptions where others takes it for long tours. It's more of an exception than a norm. That's why they made the rear triangle 115mm wide only. If it was 135mm, me and wife would have been riding it long ago. biggrin.gif

Oh ya! Akmal Basikal in Bangsar (agent for Rohloff) did try to expand the rear triangle and fit in a Rohloff. He did it but the lock nuts can't sit properly as he widen each side by 10mm and the hanger plate is at an angle.

Guys, I am looking for a new 33.9mm seatpost for my dahon bike (max load 100kg and above), any recommendation ? Thanks in advance.
*
Kimbell JAya has stocks of Lite pro 33.9 x 600mm. But light as it is, Lite pros are rated for riders up to 75 kgs only. If you are heavier but not as tall, so the seat post is not adjusted very high you can still use it. Other brands I have seen is Duccas which I used formerly but it is over RM230. Cheaper ones are from GUB but I don't know if Kimbell has it.

Yes, most seat post have lengths to 400mm. Is the extra 10mm critical? If it is then Thomson has that size you wanted.

I've had two Alfine bikes before.  I sold the first one and immediately regretted the decision.  Luck was with me and I had the opportunity to buy another identical bike in better condition and cheaper!  Thought I wouldn't ever sell but after a year, I couldn't live with that gap in the ratio, which was at my usual speed, meaning as soon as theres a slight headwind, one ratio down was too low and one up was too high......sigh

Never tried Rohloff or NuVinci but these guys are over 2 kilos, just the hub, no joke!  Make the back wheel crash through every slightest imperfection on the road. There's a NuVinci hub for sale here and I was considering it for my single speed bike, but the weight put me off.

A 10mm spread each side is doable, but as you said the dropouts needs to be angled back in....tricky.  I guess the B was never intended to go touring or be ridden at high speed.  It is just that it feels capable that made people want to do more with it.  With demand that high, they won't be coming out with a new frame anytime soon! 

Sometimes I wonder why we bother modifying foldies.  Some of you would have had ridden single speed BMX or regular bikes and I dont recall having missed not having more gears.  You would ride to the capability of the bike and accepted the top speed or you get off and push up that hill.  The way I ride my single speed is the same.  I ride up to the maximum speed, or speed that I'm comfortable at that moment to stick to it, if my legs start to go too fast, I freewheel for a bit, then crank again.  If I start pushing it, I'd soon be wishing I had more gears.

smile.gif
*
This is interesting. Why?

For me, when I was foldie biking, riding around KL/PJ becomes boring. Ride to Klang for eats, rides in Putrajaya which I have to go 2 laps to satisfy and Broga. For that my Dahon Eco C7s were enough already. Then we ventured to Parit Buntar to Taiping, Jerantut to Taman Negara, trans Titiwangsa from KKB to Raub and the 7 speed just don't cut it. SO, I started modifications after I tried Genting Peras with my 7 speeders. Me and wife needs 3 HOURS to peak. From there , the Eco C7 went 27 speed and finally all other rides that was mentioned. Why not just buy a bike with that specs?

Did you see the price of a Tern 18 speeder? That 6K plus. The cheapest then was the Dahon Visc which was selling at 2K at that time but I don't like the frame. The KHS 27 speed cost over 3K at that time. Cost is the factor. Not everyone can afford one lump sum to get the bike they wanted. So, we do it in stages. First we go for the rear mods then the front and then components. Off course lah, last time we don't need multiple gears..............in fact I rode around Penang island with a Raleigh Chopper. BUT that was last time lah! Now after so many years , no exercising , no cycling, suddenly we start to ride, the more gears the better lah!

The way you describe is true, riding at your own pace but when you are in a group of 30 riders......sometimes the others may not mind but sub consciously, you feel like an obstacle to them. If the wait is 10 to 30 minutes is fine but when others have to wait like an hour it's a bit of a let down, especially for the sweeper. When we did Jerantut to Taman Negara, there were 33 riders ! It was so hard to control that it fragmented into 5 groups. The first group, checked into their motel at 1.45pm and the rest .... re-assembled in a warong 8 kilometers from the destination in stages. The first group sat there at 3.00 pm and 3, 4, 2 riders starts converging in intervals of 30 minutes. Finally, 4 was un -accounted for rclxub.gif

1 had a crashed and hitch hiked on a gas lorry and er companion accompanied her to the hospital. another 2 had to be rescued. A concerned rider borrowed a moped and rode out and back tracked. Another rider saw it and wanted to pillion ride on it for fun. When they came back, the he came back with another rider (cramped on both legs...hahaa) and the pillion rider rode his Brompton back with the other rider who accompanied him. Wouldn't it be nice if there were more gears? With more gears , you can control your cadence and not overwork but a single speed, you can't. Maybe you can if you stay near the coastal areas where it is flat like the Netherlands.

Ok. Thanks for the info. Currently using a 400mm, would prefer a slight increase.

If 10 mm is critical, I guess you have a wrong sized frame. I don't know what bike you ride, most probably a mountain bike or the Dahon Dash. Just 10mm, I think you can get away by just clamping slightly below the safe level.

This one is even 420 mm,

Nobody has mentioned the Birdy.  Why is that?  No like??

I do like the look of it, but never ridden one.  If one comes along at a good price...... rclxm9.gif

Maybe.......

I have a friend who rides a Tyrell FX and his wife a Birdy. After a while, he sold off the Tyrell to get another Birdy. That's shows the Birdy is better right? Full suspension too! But I kind off put off with the front fork, looks weird. In Pacific Bikes stable, I still prefer the IF Reach, even the older model excites me. But these are not functional bikes , I call them boutique bikes. I serviced a Tyrell FX once and did a few rounds on it and I find the riding geometry not suitable for me. The Dahon Dash or the Performer mininvelo rides better than it. Probably my body's anatomy is wrong for the bike, hahahaa. tongue.gif

I really don't have a lot of time riding bikes but I enjoy working on them. I like to collect iconic models hence I'm thinking about the Birdy. At first I too hated the front but now I like it. I much prefer the older series. The new one, whilst nice has a softer edge to it.
The only reservation I have is to introduce another wheel size to my collection!  16, 20 then 18? Not that I would go through tyres and tubes quickly though...

Risse and Muller did cameout with a limited 10th anniversary edition of the Birdy and that came with 20 inch wheels. If you can find that in the market, you have a 20 inch model....original I mean! nod.gif Off course many also modded to 20 inch. Fei Lee of GW Cycles did a few and he's the expert about Birdys around Malaysia. icon_rolleyes.gif

53/30....sounds like two distinct sets of ratios, pretty big gap. It's not a road bike I guess. Yes I agree the front is ugly, but that is what's drawing me to it. Weird huh?  doh.gif

I'll PM you one day when I'm there. I'll try and bring one foldy back with me.
*
I think Paul is saying that he used 53 T in front and 30T at the rear. As far as I know, you can't shift that much difference in gap. Also, I have tried putting double chainrings on a foldable Tyrell, it's tricky. Only the CX, the non foldable ones has multiple chainrings. icon_rolleyes.gif

PS/ Also, I don;t think there's a30 T chainring with 130BCD in the market, is there? hmm.gif

Hahaha silly me, just assumed Paul was talking about chainrings. That's why I thought it was strange. Still a newbie here lah!

I definitely won't be able to do 53/30 up that last bit of hill!
*
If speed is not the ultimate criteria, can always go for the compact crank which is 110 BCD and that size have 50T chainrings or use mtb cranks that can hold 48T chainrings that touring bikes use. In cycling, the ultimate goal is ,
no. 1 , destination, no. 2 , level of fun and no. 3 , speed. Off course, all those must accumulate to calories burnt.

When I rode Fraser's Hill, I done that 5 to 6 times already with 2 to the peak and the rest till Gap Junction, I always take a bet with my wife on who will we meet at Gap and who we will not see. Many we see, all pumped up from KKB to the dam and that we guess will never reach. Hahahaaa. True, we see them zooming downhill even before we reach the waterfall. we need to know the terrain well and also we have to space out our energy, like budgeting money. tongue.gif Also,for those who never tried there, you should. It's a good place to ride. Peaceful and cool. Less or sometimes NO traffic thumbup.gif

Don't worry about whether you will reach or not. If you don't try, you won't know how far you can go. Start from Sg.Chilling, not KKB. Park your car just after the bridge as there's a stall there. Someone to look after the car.Start the ride and ride as far as possible. Until you drop! Then downhill down back to the car. Sooner or later, you will reach the top eventually and then finally after that, start from KKB.

You are right.  I don't try to beat speed records anyway, prefer touring speed.  What I suffer most would be the M'sian sun and heat. I've done a 45km MTB ride once and nearly died from heat stroke, hahaha.

If Fraser's Hill ride is cool. maybe I'll try if there's a group going one day.  biggrin.gif

Between road riding and offroad riding, offroad is endurance! Roadies are into speed and the peak performance. One can only get used to only one training. So, you cannot equate 45km offroad to 45km on road. On road riding, one only needs to concentrate more on peaking your performance as the roads are even where else on off road riding, a lot of other skills are needed. You have to concentrate on the line of ride, avoiding ruts, rocks and roots. This itself is sometimes too consuming for riders. Then the balancing skills and getting into tight spaces and finally the hilly terrain which needs a lot of low gear cranking and grinding.

It is not to say road riding is easier either because road riding is stressful, really stressful. Many roadies are competitive and it gets even more stressful. Off course one can say, I will just ride slow but riding in a group sometimes
drives your adrenaline high because of your peers and many try to be equal or catch up and this is disaster for those not used to it.

Most important I think is the clique you are riding with, even with foldies. Sometimes you get riders who makes a nuisance of themselves. We used to have one who always gets lost and don't want to stay with the pack and the leader and sweeper have to go all around hunting him. He could have seen something nice and sat a while reminiscing his grandmother because he saw a chicken by the roadside and that to him is why he rides, so all the others have to wait for him. While we appreciate his sentimentality, he was not thinking of others. At the same note, we also have people who organize but not taking care of their charge and sometimes just leave early. Yes, I have seen that, honestly. Hahahaaa.

My point is, riding 45 km offroad is actually very tough. I can ride Kampar to Sitiawan and ride 12 hours and still can sit down for a beer but after doing 35 km with the KLMBH here, I really wanted to take their chicken loop and go home earlier. Hahahaa. I am in the midst of organizing a ride into the jungles, from Kuala Tembeling to Kuala Lipis area. All done in the jungles. Maybe you want to join me? We ride for a day then set camp (organizers will be in 4WD and set camp and prepare food) and then ride another day and return by long boats along Sungai Jelai. This is not a jamboree or race. More of a fellowship off road ride , enjoying nature at it's best. Slow, doesn't matter if the slowest is slower than a sloth. Hahahaha. icon_rolleyes.gif

Confirmed will be this spring. Looks like a 3 speeder unit ( The rear looks wide enough for a normal Alfine gears )with normal crank and chainring so price will also be normal lah. Problem is when is Guan Chow going to bring it in or rather will they dare to bring in, seeing the Dahon Qix is stagnant. I for one will not be waiting, if either Bangkok or Singapore brings it in, 2 for me rclxms.gif

Hi sifus, just curious, let say the folding bike is not folded, can it be put in a normal car, eg myvi, at the back seat leg room?
*
Yes they can be fitted into the rear passenger seat but WHY ? It's foldable anyway, isn't that the purpose of a foldie? Also you need to take precaution as the lubricant from the chain will stain your seats. Normally they will push the front passenger seat as far as possible to the front and load the bike from the rear driver side door. They even fit in a road bike this way, off course with the front wheel taken out. I can fit 2 mountain bikes into the rear passenger seat with all wheels taken off. icon_rolleyes.gif

Hi all sifu,

I'm thinking of getting into cycling, and wanted to buy folding bikes because of the versatility it gives. For now, I think mainly I'll start by cycling to work, which is about 7-8km distance.

I'm planning to start off with a budget bike like Raleigh Ugo.
Is this a good choice or is there a better alternative?
I learned from this thread that brand like Dahon or Tern are better quality, but the cheapest I saw from the net for these bikes is about RM1,300.
I wanted something that comes with a bit quality and upgradable, but not too expensive.

Hope all sifu here can give me some advise on how should I start.
Thanks!

Raleigh Ugo is a good choice to start and if you want to save even more, look for a used unit. The front chainring of the Ugo can't be upgraded though unless you want to do some metal grinding work on the frame. tongue.gif My advise, look for a used Dahon Route. Same price as new Ugo and you don't have to change bike later.

Remember, get a helmet and a pair of gloves!

Hi all sifus, need your advice on which folding bike to get. 1st time buyer with no experience or knowledge on FB. Did read up on V3 beginner guide tho'. Mostly use for casual rides 2-3 times a week. Space is an issue as I live in HK and budget preferably below RM1000 = HKD2000. These are the ones I've looked at, thanks in advance.

I would prefer the 2 on the link above. More proven especially the no.4 link. Since most of the ones you short listed are single chain ring units ( only one gear in front ). icon_rolleyes.gif

Usually the tourers or cyclist I met, never ride up Gunong Raya. It is one of the best place to ride. Only 13 kilometers up to the Binariang satellite station. The tea house is operating or not, I have no idea but the view is really breath taking (if there are no haze lah). Starting place is in Jalan Ulu Melaka and you have to pay toll to use the road.
