Sturmey Archer 3 speed hub maintenance

This week, I decided to thinker some more and overhaul my Brompton's 3 speed SA hub. First was to remove the rear wheel. To do this, follow the instruction from brompton (youtube) and it is straight forward.

After getting the rear wheel out, I started removing the nuts and cones from both ends, then the ballring cap that holds the mechanism inside. It would require to do some hammering, just use your rubber or wooden mallet and a screw driver. After removing the cap, you can see the axle going inside with clutch, springs and all those parts greased inside. Remember to remember how each part are placed in sequence. Used kerosene to clean and remove those old grease, dried them up and put them back together. Greased it with teflon grease and everything seems smooth and clean. When putting it back together, one tip is to put back the puller chain first to hold the small piece of metal that pulls the clutch.

New Look

Replaced all the brown leather wraps with a black foam wrap. Managed to replace the rear bolts with titanium ones. Oh yeah and changed to cambium brooks saddle too :)

Ready to ride!

This is my everyday ride to the office. Haven't had time to shop for a brompton bag yet so used my old handlebar bag.

Wasting time taking pics of my mini foldie

Wet Ride!

Went for a 50km ride from east to central then back. I have to go to the gym to get my jiu jitsu gi so why not cycle. I've been injured since the last competition so i cant train. I need to get some alternate exercise of some sort.

We got caught by the rain on our way back so we have to take some shelter.

Good thing I have those fenders on. Lights, bags and GPS units are all rain proof so its all good.

But be reminded always. Be extra careful when riding wet, it can be very slippery at times. Always bring extra lights, batteries, water and snacks ;)

Coffee with the Wifey

Finally convinced my commander in chief to join me for a ride and a coffee :)

We took our eldest to her cathecism class then we took a quick break. She was a bit slow since she hasn't cycle for quite some years now but that's fine.

My 2nd Foldie

Giving in

After months of my beloved mini bike, I gave in. I bought my second foldie, a Brompton P6R. Pre-owned but still in good condition. It was from a good friend of mine, also a foldie person. It is in black color with leather straps and grips, added by my friend.

Folded together with my mini.

Fits perfectly in my cubicle

Comes with stock saddle, pedals, breaks and gears. So far I'm happy with it specially on how easy and compact it is to fold.

Cleaning the Brompton

The first thing I did when I got the bike was to clean it. It came in good condition but I really want it clean based on my own standards. My plan is to take it apart, clean it, grease or lube it, then put it back together.

The first one to go was the drivetrain, since this should be the dirtiest part. Removed the chain via chain link, remove the rear bolts, tensioner and sprockets. I have a bottle of paint thinner left from my old painting project so I used it to soak all the parts. Paint thinner is very good in removing the grit , gunks and grease. You can google the procedure for removing these parts, its easy. Just remember to take note all the correct placements of the parts that were disassembled. After some soaking and brushing, drivetrain parts are now clean and grease free. Lube them with dry lube and grease before putting them back together.

Then the brake sets. There's some dirt and gunks trapped between the calipers so it's time for some cleaning too. Disassembled both the front and rear caliper brakes, soak with the thinner, lube and clean as new :)

Finally, the front hub axle. Removed nuts from both sides, pull the axle, remove the ball bearings, soak, wipe, grease, done.

Well, it sounded easy to do it but it will really require some planning, time and proper tools to get the job done. I even broke the rear brake cable when I was putting it back and have to buy a new one.

My first foldie

Living in a city like Singapore, cycling is one of the best options for commuting specially that most of the roads are bike friendly. So on with my first purchase.

Here are the choices that I considered:

• Dahon
• Tern
• Brompton
• Vert
• Lamborghini
• Java

Since many of my friends already are foldie owners, most of my decision making are influenced by asking their advice and experience.

Some factors I considered for my decision:

Price

Price is always a great factor on making any purchasing decision.

Aesthetics

I want a bike that looks slick and curvy, just my personal preference.

Build Quality

I don't want to buy something very cheap but suffer after. At least something that will last for years.

Parts Availability and Compatibility

As I plan to slowly upgrade any parts if I can, parts availability is a big plus. Having said that, the bike should be able to support these "upgrades".

Brand Reputation 

Known brands don't always have the upper end and most of the time will cost more but having the popular brand doesn't hurt either.


So starts with my search. My friends own Terns, Bromptons, Tyrells and Lambo. Bromptons and Tyrells are out since both are pricey and out of my budget. Even used Bromptons are so expensive, I can buy 2 new Terns/Dahons for the same price. I was leaning more to Tern, Dahon, Java and Vert.

There are some other new brands like Hachiko and Aleoca which are selling cheap foldies but you get what you pay for. I've seen many of these foldies around and in comparison to top brands, the quality is far lesser. Although I won't count them out but for now, I won't be picking any of them up soon.

Vert is a relatively new brand but offering some descent bikes with reasonable price. V6 and V8 models looks beautiful but I heard "some" not so good reviews about this brand. Here is the V8 model from bicyclesg.com, one of the dealers here in Singapore.

V8 Model costs around 398SGD posted on their site (14/07/2014)

Java is another up and coming brand which is offers quality foldies. Bikeactually.sg is a known distributor of Java here in Singapore. Here is Fit-16, a 618 SGD bike from Java:

This bike is one that made my list. Feature rich comfortable bike. Colorway is slick. Gray, black and red is beautiful. The "down side" for me is the disk brakes(I prefer clamp or v brakes) and the not so curvy frame.

So down with my last two options: Tern or Dahon.

We all know what's the history between this two companies. Tern(owned by Hon's wife and son) basically was a "spin off" from Dahon and Dahon suing Tern for patents etc. etc. So more of the bikes from these two companies are very similar in terms of design and looks.

They both offer a plethora of foldies to choose from. From starters, mid range and high ends. Problem I have now is, those bikes that I want, is in the mid to high range. Meaning it will cost more. So here are my options, buy a low end one, then gradually upgrade the parts. Or buy a used one then upgrade.

So I went into local sites, forums, craiglists to get a used one. One local site, togoparts.com has some good ads selling foldies and parts which I often check. Then finally, I found a post in craiglist Singapore. It is a used 2014 Mini Cooper folding bike. The price is 600 SGD. So I checked the specs of this bike, it's basically a Dahon Vybe frame(from the looks of it) then Mini upgraded the parts. The bike cost around 950 SGD brand new from the BMW site.

Here is the picture of the BMW Mini Cooper foldable bike:

 

This bike looks gorgeous. It comes with 2 colors, black and lime green. Lime green being a bit expensive for its additional add ons. The owner was selling the lime green version(though I prefer the black color).

There are not so many reviews about this bike. I probably seen about 2 or 4 articles about it but that's it. So I went and test the bike. The comfort and ride is awesome. Sturdy and not stiff. Shifting is smooth. That Neos 2 Rear Derailleur and Teflon coated Taya chains are perfect. I'm sold. I bought it. Next. Upgrades.
