Thinking about getting a bike for cycling in and out of work.
I've seen a few people here talking about cycleways.com on Parnell St.
Are they the best place in town to get a bike ?

People tend to recommend cycleways on Parnell St when buying bicycles in town. They have a website, decent prices and are well located. Other places are cyclogical on the quays, Joe Dalys in Dundrum, and a bunch in Ranelagh, Rathmines, Georges St etc. Other might add more here.

Online shops are www.chainreactions.com and http://www.evanscycles.com/

When buying bicycles, there are three main types, road bikes, mountain bikes and hybrids. Roadbikes or 'Racers' are what ya see in the Tour de France. They go fast. You won't be reading this if you are looking to buy a roadbike.

Mountain bikes are what you had as a kid, typicaly heavy enough bikes, flat handle bars, reasonably upright posture when cycling them. Mountain bikes can come with front suspension (hard tail frame), front and rear suspension (full suspension) and no suspension.

Hybrid bikes are as you might think, a combination of the two above types. The posture of a hybrid is the same as a mountain bike, but the bikes tend to be lighter, thinner tyres and not have suspension. Or at least only have suspension on the saddle post. For cycling through town as the original question asked, I would recommend a hybrid bicycle with no suspension.

Suspension is somewhat debatable. I cycle a mountain bike with front suspension and thinish tyres. (1.5") I prefer to have a bit of suspension as the roads on my route can be cack and occasionally it's necessary to mount the kerb to go around traffic. However, suspension detracts from your speed, by absorbing some of the the downward force applied when pushing on the peddle. You might think, 'Well feck that, I won't be zooming around, the suspension will keep me comfortable' but after a few weeks of cycling, being able to go a bit faster can start to look quite appealing. A compromise is to ensure that the bicycle you can buy enables you to lock out the suspension. You still have the added weight of the heavy front forks, but the lack of suspension will result in a speed up. (I have aspirations of going mountain biking, which is why I stick with the mountain bike and don't get a hybrid)

Check as many bits as possible (pedals, pedal housing, brake/gear levels and so on) are rust-proof. Pedals should be sealed to prevent road gunk getting in and causing problems.

Basically, ask the sales guy:

"What's most likely to break first?" and "How much will it cost to fix?"

He'll tell you the brake / gear cables might need tuning after a few weeks on the road. Reply "yes, obviously, but apart from that ...?" :) Also, see will he throw in your first servcie (to tighten said cables) for free.

See is there a front chain guard to stop your trouser cuffs getting destroyed with oil :) Be prepared to tuck your trousers into your socks.


Accessories

Bells

Bells are useful to have and in fact are a legal requirement. They can be slightly dangerous though. You shouldn't rely on a person getting out of the way when you ring your bell, they tend to ignore em. Always be ready to brake when going through an area with lots of pedestrians, don't worry so much about making sure they know they have inspired your ire by ringing your bell furiously.

Illumination

Buy a decent set of lights, rear and front. Get a reflective, Hi-Vis jacket. I cycle with strong front and back lights on my bicycle and weaker flashing lights that I hang on my person, front and back. Reason being that if I come off the bike at night onto the road, at least my wee flashing lights might prevent a car from squashing me.

> I actually found it cheaper going into a builders' supply store > looking for hi-vis stuff.

Definitely agree on this one. If you're around DCU, head into Heitons up in Santry.


In the rain

Get a light rain-jacket, and waterproof trousers. Waterproof boots help too.

You'll heat up in no time once you get going, so don't smother yourself with overcoats and whatnot. Wear a decent pair of gloves (I use padded ski gloves) as your hands tend to freeze when cycling in cold rain. Gloves are also handy in that they stop you getting cut when you skid off on wet, icy roads.

Basically, as long as you're wrapped up, cycling in the rain is no hassle. Just remember to allow extra stopping distance. Your brakes will be wet. And if you try to jam on, the whole bike will just shoot from under you :)

Disc brakes can be an advantage here if you are willing to fork (ho ho) out a bit of extra cash. They are superior to v-brakes in the wet.

I tend to not wear waterproof trousers as I end up sweating so much in em that I get just as wet as if I'd been rained on. Decent waterproof trousers may prevent this.

Helmets

There is substantial debate as to the merits of helmets for cycling. I won't get into it particularly much. Whilst they may not safe your life, they can make certain falls less painful. All the stores mentioned at the top will stock em. Any helmet they sell will adhere to the safety regulations, the most important thing is to buy one that is comfortable on your noggin.

Keeping your bicycle

I did a lot of reading about this a few months ago. Have a look at http://www.sheldonbrown.com. He has lots of cycling articles and a good one on bicycle locks.

The end points were :

  1. Its all about pissing the thief off and making them look for an easier target.
  2. Use two different locks, the thief will need to carry two seperate pieces of equipment to nick the bike. I use a chain/padlock & Ulock. More on this.
  3. If you have a detachable front wheel, take it off and lock it to the back wheel. Lock it with the ulock, passing it through the rear triange and onto something immovable. The less space available in the lock, less room for leverage on behalf of the thief. Taking the wheel with you doesn't increase your security.
  4. Take your detachable saddle with you, or replace the quick release bolt with an alan key one. Someone will just nick your saddle and chuck it in a bin, cause they are scummers.
  5. Other obvious things. Park it in a public place, not in some secret location no one will ever find it. A secret location means a thief can spend their time working away on the locks without worrying about passers by. Lock it to an immovable object.

That's most of what I can remember. The lock I settled on was a rather large Abus Granit lock and chain for 90 euro. I bought it in The Great Outdoors, funnily enough. They have a reasonable bicycle accessories section in there. Last time I went in, they were out of that exact lock though. You could also head into a locksmith and ask for a boron alloy chain and good padlock. Something like a 13mm boron chain requires a hydraulic bolt cutter to get through it. The best padlocks are the ones that only have room for one link to be fit through. No space for a crowbar to get in there then.

My second lock is a fairly cheap combination ULock. If you get a Ulock, make sure it doesn't have a circle key. Google for Bic pen attacks ! The best Ulocks are Kryptonite ones. As above, make sure you get a flat key one. I see the New Yorker one mentioned a lot.

If you get a large chain & padlock, leave em at your target location.. I.e I leave mine locked to the bike rack in DCU, it's too heavy to be carrying it on my bike everyday. I have the ulock for quick tops. Also, never leave the padlock resting on the ground, you are leaving it open to getting whacked with a hammer. Wrap the chain good and tight about the frame and the 'immovable object'.

That's around about it. In conclusion, get a Granit chain and a Ulock & don't ever lock your bicyle in the city center if you love it.


Good cycle practices

People might put in comments about cycling through town, what to do and what not to do. There are a number of books about cycling through urban locations, a google will find em.

Road Positioning

When cycling through town, or for that fact anywhere, there are occasions when it is safest to move into the center of the lane. This is particularly the case when there is not enough room for a car to safely overtake you. By cycling in the middle of the lane, the car will not attempt it. If you are over the in kerb they might.

Similarly if cycling along a line of parked cars, do not stay in close, give them the mandatory door length space between you and them.

If approaching a left turn, it might be best to enter into the main lane of traffic. This way cars turning left will not squash you as they turn. Indicate of course that you are moving into the main lane of traffic. I find that drivers invariably allow you in, if you indicate, as they are nervous of making you go spat. Also, moving into the main lane makes it easier for oncoming cars turning to their right to see you and also for cars emerging from the left turn ahead to see you. (this is also why a front light at night is important, so as oncoming turning cars can see you)

Cycle Lanes

It is mandatory to use cycle lanes when they are available. That is, a Garda can bust you for using the road, when a cyclelane is present, even if it's safer to use the road. However, the cycle lanes must be correctly defined and marked. There are a number of laws relating to the use of cycle lanes and cycling on the road in general. Theses are nicely presented at http://www.geocities.com/cyclopath2001/legal.htm

Braking

As mentioned above disc brakes offer superior performance to V-Brakes, especially in wet weather. When braking, the various books and sites I've read advise using your front brakes first, not your back brakes. Front brakes offer much greater stopping force. To avoid going head over heels, don't jam on the brakes as hard as you can. If travelling particularly fast, shove your arse up and over the back of the seat, moving your weight over the back of the bike, this will prevent you flying forward.

Be particularly careful in wet weather, skidding on your front brakes is remarkably scary.

Check your brake pads regularly enough, if you head a scraping sound from em when you brake, make sure you change them quickly. You might have worn the pad away and the metal underneath is shredding your wheel rim to pieces.

Traffic Lights

Various Gurus differ on traffic lights. At a dangerous junction, where it is difficult for a cyclist to get in the correct lane, it can sometimes be safer to move out while the light is red so as to get ahead of the waiting cars.

In general I obey all junction traffic lights, but tend to go through pedestrian lights. This is illegal of course, you are required to obey all lights.
