Dahon Mu Uno question

A neighbor has a Mu Uno with rack, bungee and fenders and front brake for sale for $250. Am I right that this is a crazy good deal? It's single speed but I can change out the rear cog as needed, I believe, to get comfortable gearing. It would be my backup bike that I CAN lock up outside the movies and also a fun bike for my adult son to ride when he travels. It looks to be in perfect condition - I am seeing it tomorrow morning. Good price and good bike???

Or buy them both and close out 2018 with a bang! The Mu Uno is a good bike.. I've had a number of them through the years.. perfect for 2 speed conversion.. or belt drive .. or 451 conversion.. I've done all of those mods..

Oooh, how do you do a 2 speed conversion? Don't want an IGH as it makes flats a pain. They already sold one of them!

Yes that's a nice bike, go get it! For 2-speed without shifters you can use a Sturmey-Archer kickback hub or SRAM Automatix.

The newer IG hubs have quick disconnects of the shifting cable to make flat repair easier. Key question is if the dropout spacing is same for the single as for an IG hub. 99% of time, I don't remove rear wheel to fix flat (unless I need to change tube), I just stand the bike upside down, lever half the tire off on the non-drive side, pull out tube and inflate and inspect for leak, patch with sticky patch, put tube back in and tire on, re-inflate.

An external 2-speed would require a minimal derailleur to both switch gears and maintain chain tension. lacking a derailleur hanger, you can get derailleurs with an integral "claw mount" that goes under the axle nut. I've used those to convert from Dahon "compact" derailleurs which are both expensive and junk. The new derailleur shifts better, shifting direction is now "normal" and not reversed, and because the derailleur is further aft, the wheel comes off and on much easier. Also, the derailleur cage is longer so can accommodate a wider range cassette and/or double crank.

I think I will stick with the single speed for now. It came with all kinds of stuff....fenders, rack, bell, rear view mirror, etc., none of which I want. Anyone out there interested in these parts, let me know. I'd sell them for just a tiny bit above shipping cost to pay for my time packing them. Once I get more used to stopping with the coaster brake, I will probably take off the front brake, too. The seat post has the biologic pump inside it (and it works!) but I carry a tiny pump so I'm wondering if it is possible to remove that pump and just use the seat post? It rides really nicely - they hardly used them, the tires still have the little "feelers" on them. A few scratches and that's about it. I think it willl serve me well as a backup bike as long as I can keep my adult son from stealing it =). I put some much narrower handlebars on it that I had since the stock ones were way to wide for me and I didn't want to cut them down in case my son wants to use it. Pics are before and after.

Looks like I can get a litepro seatpost around 320 grams for pretty cheap, so if anyone is looking for a BioLogic™ Zorin PostPump™, 34 x 580 mm, let me know. $25+shipping. I'll drop about a pound without it. It's a pretty cool invention if you don't already have a mini pump or cannisters. I also took off the double kickstand. Super light bike loaded down with so much stuff!!!

Having had experience with that coaster brake and knowing where you live and the kind of hills you encounter, I'd definitely leave the front brake on the bike. A front brake is more important than a rear brake, much like a car or motorcycle..

I won't be using the Mu Uno on anything even remotely hilly; that's what the Bike Friday is for =). Point taken, though, I'll leave it for now. The Mu Uno is basically to ride to Oakland and lock up at the Grand Lake Theater (since they're not cool with me bringing my BF folded up inside). All the N/S rides are pretty flat; anything E or W will get the 8 speed.

Yey yep, I've had a couple UNOs and put a front brake on both. Coasters work, but I always grab for that phantom lever in a panic stop, my brain doesn't instinctively remember to back-pedal.

Nice bike!

Just from the little bit of time I had with it today, it does seem a nice bike. I'd never even heard of the Mu Uno til I read about it here on the forum. The handlebar is quite a bit higher than the one on my Bike Friday (which is just shy of level with the saddle) so it's a much more relaxed riding position. Not sure how I will take to it - I like a fair amount of stretch for my back. But it won't get used all that much so I'm sure I can live with the difference. My son is coming by tomorrow (we go to brunch every NY day) and he can't wait to give it a go --- if it has any failings I am sure he will discover them as he is murder on a bike. Bracing myself for the battle to pry it from his greedy not-so-little hands =). Btw, Happy New Year!!!

Picked up a LitePro seat post to replace the very heavy Biologic one with the pump inside (anyone want one?) and that has made a big difference in weight. The bike is still too heavy for me to carry it for very long, but replacing the marathon racers with lighter weight tires in the near future will help. I put together my "single speed flat kit" which is basically a 15mm and 2 10mm stubby wrenches + 20" tube; it will live on the bike in a tiny handlebar bag. My patches and tire levers, etc., are in my sling bag I wear along with my Pakit tube. Having just been out in the rain, I have to say the coaster brake is pretty awesome!!! No screeching when it rains, it stays dry, and stops just like always. Less crap to clean off the bike, too, since it rides higher from the ground than my Pakit. The Mu will definitely be my bad weather bike =).
