A bit late to the party... However here is my input.

I have two of these, believe both of mine are 1984 models, one has the S-A hub the other a Sachs. several other subtle differences. I have one tricked out to take with me on my travels, the other I haven't done much with. I picked the pair up for $75 at a local thrift store.

Only parts I have had issues finding are the brake blocks, they are made at an angle to meet the rim. I was able to scrub enough of the old hard rubber off the originals to make them work, more or less.

I will ride the bike distances up to ~5 miles, much after that I want something better, also being a large person (6'-2" 225#) I find the bike a bit squirrely when being ridden hard, like up hills or sprinting away from traffic lights. Other than that is fit the bill for what I needed at the time. Eventually it may get replaced by a Brompton, or maybe not.

@wahoonc I normally don't ride long distance with mine either. It's kind of the neighborhood cruiser. However I did take it on a 6 mile ride on a nearby trail over the weekend and it held up quite well. The pavement wasn't the smoothest but I still enjoyed the ride!

1. Make absolutely sure you repack the headset and front hub, if they're like mine there will be no grease at all in there and you'll notice an immediate improvement in handling and speed.
2. I would change the saddle, it's unduly heavy and creaky.
3. If you want to replace the cranks you can either find a lighter, cr-mo one piece option like I did, or get an American bottom bracket with a square taper spindle. Do not, as I did, try to make an American to Euro bb adapter work with this frame, heartache lies that way.
4. If you regularly fold this bike, take a sharp knife and cut off all the little nubs on the stock pedals or they will scrape up the top tube.
5. If the bike is not folding tightly or feeling jangly, there is a very effective adjustment screw built into the hinge clamp, you can adjust it using a screwdriver and make it as tight as possible while still being able to open and close.
6. Should you choose to replace the seatpost, do not listen to the World Wide Interwebz which will lead you to believe that it's 33.9. It's nowhere near that, maybe 32, measure it with a caliper. Or, I now have a beautiful 33.9 post in my parts bin that you can hold over your bike, if you want that experience.
7. Replacing the tires will make a big difference in ride quality and speed. Don't go cheap on this one aspect, I briefly rode mine on kids knobby tires when I had a blowout on vacation and it was horrific.
8. Be careful what you put on the handlebars, they are finicky when it comes to the fold. Nothing can be popping up to high, either. I'm going to include some bell and lighting suggestions in pictures.
Thanks @devinfan for this list, you just can't imagine how helpful it was for me. I was searching online for help on the Dahon Classic V I bough and this was really extremely helpful.

1. I have repacked everthing except the headset I don't know how to open it. Do I need an special tool?
2. First thing I did, the original one is terrible imo.
3. I bit lost about this one. The original crank is incredible heavy but I don't know what to search for a replacement. Cand you share some model or link to one that suitable for this bike?
4. Done, thanks.
5. This is a live solver, period. The bike now closes perfectly.
6. No money for that for now, but I will try to find a cheap one that weights a bit less.
7. Done, waiting for a couple of marathons racing tires.
8. Noted, thanks.

ps - sorry for my english

Very glad I could be of some help!

1. I didnít have a special tool for my headset. First remove the black plastic cover, it just pops off. Then I used a large Robertson screwdriver which I put into the top notched ring and hammered until it loosened, followed by the lower ring. Just remember the order everything goes in. Clean the bearings, heavily re-grease and re-assemble and you will notice a huge difference.

3. Unless you want to make modifications to your frame that I was unwilling to do, youíre stuck with an Ashtabula/one-piece crank. I was lucky enough to find an SR Tubular crank that is CrMo, hollow and very light. Itís a great crank and they come up now and then. Otherwise just search up cromoly one-piece crank and youíll be in business.

Enjoy your bike, they are lots of fun!!

1. For the headset someone recommended me this tool and I was lucky since I had one (never used it before, now I know what it's for). It worked very well.

3. For now I think I will stay with my current crank, if I find myself using the bike quite a lot I will invest in one the solutions you mention, since the original one is really heavy, a big piece of metal really!

Enjoy your bike, they are lots of fun!!
Thanks! This weekend there is a bike festival in my town and I hope I will have my bike ready by then.
