    Cut back a little on your high end audio stuffs, and you can have a pretty good ride :P

    Pete, I know you are still looking for a bike and so is nOelnOel who is rather
    keen on getting a hybrid and went out to do her research for the best bike
    (value for money).

    Cycling is my recreational hobby and has been cycling regularly six years ago.
    As a school boy I got hold of an old Raleigh and use it to cycle to school at
    Baker Road. In my adult life I left cycling totally and came back only in 2004.

    According to nOelnOel the Helios F300 cost about S$800 which is the same
    price as the Diamondback Insight 2. I've always explain to people who has
    a fixed budget way below to get even a decent quality bike that will provide
    not only the comfort but a daily special riding experience for the rider.

    The bike will last you a long long time if you don't crash it. Let say you'll
    give the bike a lifespan of ten years and paying $800 means it cost you only
    $80/- per year. I'm pretty sure even a young working adult can afford
    that and it's cheaper than your mobile phone bill and your MRT/bus fare
    where you have to pay around from $35 - $120 per month. To give a more
    financial look at it, you are paying only about $0.22 per day. I think you
    spent more than that for a cup of coffee per day.

    Pete, I'll come to the problems of newbies taking up cycling as an activity
    and finding problems that he won't want to tell anyone. For that fixed
    budget you may have to look for a used hybrid or a good quality used MTB.
    The pics are for you to know what you are paying for. Just words without
    visuals simply cannot complete the task of providing better communication.

    Fixed Gear Bicycle for easy and daily cycling
    around the neighbourhood.


    The fixed gear bike is popular because of its
    easy maintainence. This one is from Dura and
    cost around $100 and comes with bike stand,
    and rear rack. The front basket cost around
    $12.00 and the pair of mirrors cost another $10.00
    It has 26" wheel set and decent tires (1.95).
    There is a model for man too and comes in white,
    yellow and silver colour. I got the silver one with
    18 speed and rode it daily to work.

    Sorry Ryan, this bike uses only one gear and can coast. I think the word
    "fixed gear" should not be used for this kind of bike. The more appropriate
    word should be "single gear". You are ride, the real fixie has no brakes
    and cannot coast. I have yet to try on one too. Thanks for the alert to
    the error.

    A street bike with fat tires (2.2) for cycling to work

    An affordable bike for daily cycling activity. This Dura 18 speed bike with rigid fork has been with me for two years where I ride it daily to work. The front basket, backlight, bell, and the bar-ends are additional accessories. All in cost around S$140 with a change of a new set of 2.2 tires. Comes in white, silver and even yellow colour for your choice.

The whole idea that even in the ideal of an active physical activity, equipment are invented to optimize your ability to engage yourself physically be it to keep really fit or just have a good time, you need something as silly as an electronic gear shifter to make a few more bucks. For sure there will be a lot who will clamor for it like an ipad. But really...when is too far... really too 'far'. Already we have so many electric bike being rode into four foot way of shophouses like they own it. Zip on footpath and honking at people to move away. I am all for people getting on a bike and just enjoy riding.. in whatever physical shape or form. But thing like that just does not need to exist... I am only talk about the technology that has gone so wrong. For lazy people .. nah that is not my 'beef'. heheheheh
    just to correct this statement "...the technology that has gone so wrong."

    It isn't technology itself going wrong but the irresponsible APPLICATION of technology. Technology itself has no wrong or right; it is how man uses it that causes goodness or harm.

    I decided to turn the pleasure ride into a learning experience.

    Ability is what you're capable of doing.
    Motivation determines what you do.
    What determines how well you do it?
    Well, someone told me that a person
    cannot travel within and stand still without.

    Hey guys, I would like to ask a noob question...
    I have a crossbreed which is running on slim kenda tyres, size is 700 x 25 if i remember correctly...
    And on the tyres it stated that max pressure is 90psi, but I still feel that the tyres are under-pumped(especially the rear)
    Question is, what is the desired air pressure to pump the tyres?
    I know our own weight will also determine the desired tyre pressure, I'm weighing about 68kgs
    I'm just scared that I might burst the tyres

    Side walls of the tyre should made mention the desired pump pressure. Road bike wheels typically 100 to 120 psi, but I was told all the while to slightly underpump in singapore - I usually do 90-100 on mine. Actually by the time it hits 90psi, it gets pretty turgid already.

    Hmm the prob is wen I sit on the bike, my rear tyre was deflated like as if it's under-pumped...
    I read somewhere and came across this formula : The slimmer the tyres are/the heavier you are, the higher the air pressure needed for the tyres...

    The heavier the rider+frame the higher the pressure recommended compared to a lighter overall for the same tyre, and the rear tyre typically needs a slightly higher pressure since the rear takes a greater proportion of overall weight.
    I am not sure of any formula to calculate to the exact numbers though.

    ( I still pump both my tyres to same pressure and they ride pretty well, usually flatting after clocking under 80km rides, I am abt 73kg )

    How to optimizing your tire pressure for your weight?

    Here is a summary from what I have learned about tire pressure etc etc...

    1. The higher the air pressure, the less the tire will deflect. However the ride becomes excessively harsh, and traction will be reduced.

    2. Surprising over-inflation increases rolling resistance, because of the increase in vibration.

    3. Most cyclists would agree that wider tires call for lower pressures, narrower tires call for higher pressures.

    4. A tire is supposed to deflect a bit under load. This deflection the whole purpose of pneumatic tires. When you sit on your bike, your tires should visibly bulge out at least a bit under your weight. If they don't, they're overinflated.
    An overinflated tire is more prone to damage from sharp rocks and similar road hazards.

    5. For experience and learning purposes cyclists should experiment with different pressures, and often even vary the pressure for different surface conditions.

    6. Optimal pressure will depend on the load it is being asked to support. A heavier rider needs a higher pressure than a lighter rider, for identical tires.

    7. Most bicycles usually have more weight on the rear wheel than on the front, the rear tire should almost always be inflated to a higher pressure than the front, typically by about 10%. (this is a common suggestion)

    8. Rider skill also play a part. While a more experienced cyclists learn to "get light" for a fraction of a second while going over rough patches; newbies tend to sit harder on the saddle, increasing the risk of pinch flats.

    Hmm I guess I should have the tubes checked before pumping again, does over-inflation of the tyres causes the tubes to have an air leak?

    Carrying your equipment

    It is advisable to carry your stuff on the rear rack rather than on
    backpack over your shoulder while riding your bike. I have seen
    cyclists having their tripod and backpack over their shoulders while
    cycling without knowing that it is not only uncomfortable but very
    dangerous especially with that extra weight.

    Here is an example of how you can carry your Gizto tripod
    and your canvas camera bag on the rear rack of a double
    suspension MTB. You can ride your bike more comfortably this way.

    I would have a new set of tubes to be sure. Old tubes do leak. Nowadays LBS don't
    repair leaked tubes anymore. Please read the article on over and under-inflation

    It's common sense the LBS kept their mouth shut on such matters. So if you find that
    the tire keeps deflating, change the tubes immediately.

    To build trust and bonding in this community we got to get to know one another better.
    How about telling us what kind of riding experience you have been through and what bike
    are you riding now? Perhaps share with us what would you like to invest in when you are
    going to get your next bike. Cheers for joining us in this thread.

    Encouraging you to accomplish some cycling experience each day.
    Believe you can do it for your belief is your inward conviction to the
    activity of cycling.

    Me seldom ride off road though I love to. Maybe when work not that busy. Types of bikes I own now :
    1 alu full sus MTB
    1 Ti full sus MTB
    1 Alu hardtail MTB
    1 Ti road bike
    1 Alu road bike
    1 Alu folding bike
    1 Alu full sus folding bike and lastly
    1 Cromoly touring folding bike coming soon

    anyone here is good in taking stitching shot ? Maybe can learn something when we meet.
