I still go for the Raleigh Ugo. My suspicion, if a bike gives good components and the price is still low, there must be a drawback somewhere!  hmm.gif  The Trinx 16 speed is shodded with 451 (22inch ) wheels, Shimano Claris 2 X 8 speed gearing and the price can be had for just RM850. I see many riders buys that after persusasion from shops and see them in rides and gradually dissappear. Something must have stopped them riding!

PS/ If you meet the right group and understanding group of riders and become regular, I am very sure you will move up.  tongue.gif

Ok great, ugo it is then. Theres a seller in kajang (bicycle malaysia) posted advert in bbs selling ugo for rm750.

i suggest that you borrow her frens' bikes. diff brand n model etc. to have a ride.
to get a feel of it...

bike with small wheels feels different..
90kg on a folding bike feels diff than 60kg on a folding bike....

mebe u get so used to twisting the throttle... on two wheels...

having the need to crank that leg muscle up the hill ... may be too 'potong stim... '  biggrin.gif

She has a java fit. I am fine with small bikes mainly i dont plan on riding fast and yes the main purpose is to get me sweating and exercising, so even if the bike is heavy and i had to ride harder than a 26" mtb or 29" roadie, so be it.. Plus as added benefit when i get slimmer and reduce my body weight, the power to weight ratio on the bike improves too smile.gif

if u feel ok with the java fit.. then shud be ok la with others...

some heavy rider will feel that some 'cheaper' bike is not solid enuf..
there is a difference when the rider is heavy... esp foldie, where there are joints on frame n post...
long seat post doesn't help.. ..
brake oso tak makan when down slope...
when cranking force is high, cheaper component oso takut nanti break....

but when ur main purpose is to exercise,.. then all those 'feel' are kinda pointless...
just ride man.. the more difficult the bike rides.. the more u will loose weight... just don't cancel it with extra food... biggrin.gif

I am 53 and weighs almost 100 kg. So, I guess I cannot afford to ride cheaper foldies. At least Dahons specifies that it can take 105 kg while most others dare not specify. I am also a slow rider, imagine carrying 2 bags of cement wherever you go! nod.gif Anyway, I have ridden on a lot of routes and the furthest and toughest is the Hulu Langat to Titi route, to and fro. To explain it, a foldie is actually much easier to ride than the other 2 types, namely MTB and roadie. A foldie which has smaller diameter wheels climbs easier than the bigger wheel bikes. Main disadvantage of the foldie is off course the lack of gearings which I have successfully manage to overcome by modding to 27 speed and that plus the smaller wheel is actually easier to ride albeit slower. A roadie is off course much faster because of the larger wheels and also smaller width of the tires. But it needs very strong legs to pedal.

They tend to be hard to ride because most riders start with the least gears! I see 7 or 8 speed is common. So, when they start, it takes a lot of effort but they do give good training though. Eg. when I started with 7 speed Eco C7, I practically use all the gear range when riding in Putrajaya lakeside. As I ride there twice weekly, by the third week, I use only 3 gears and now after a year plus, I don't need to change gears at all. That doesn't mean I use the highest gear ( 53T in front and 11 T at the back). I only used this for downhill pedalling and on flats it's the 3rd gear. Some can pedal the highest with no problem but I am old already. sweat.gif With the 3rd gear and a cadence (crank rotation per minute) of about 65 to 70, I can ride 20kmh on flats. icon_rolleyes.gif

A bike helmet is a helmet. Prowell, Speed gear etc. or the more expensive ones like Giro, Uvex, Specilalized, Casco etc , they serve only one purpose, skull protection. Bear in mind, the helmet can sustain impact only once! nod.gif If you crash and it usually breaks, you have to get another one. A tip is, try to buy one which has the shell and foam incorporated. This means the outer layer and the foam are joined. If you look at the cheaper ones, the outer layer is a layer of plastic and they are just laid on top of the foam.

Bravo, sifu etigge. Really respect you for your sport spirit. I riding almost everyday inside my condo for around 1 hour. The road is rough and got few bump. My bike is vibrating a lot for running through bump and small path holes in each lap as I don't slow down. I don't know how long my KHS can last if I keep on like this. I already start riding for 4 month and so far still ok. I am thinking to get another mini velo 20" Non foldable bike. Do you have any experience on it? tongue.gif

Velo is a faster bike as it is supposed to be a mini roadie. With the right set up, it can actually catch up with roadies if you are strong enough. The only advantage of a velo in your case is probably the weight. Velo is much lighter. Don't worry about your KHS, it is strong enough to handle the few bumps. So far I see my fellow riders on KHS, none have any complaints.

Thanks for the info. I am thinking to upgrade my single chainring to double crank set. My front crank is now 48t, go uphill need more effort. How about 52/38t? If after upgrade do it encounter chain drop or mechanical issue? Still thinking it. My current setting is very smooth on gear change. thumbup.gif

Upgrade is like a must do activity.

After I get my first bike, I upgrade, then ride some more, then upgrade again.

It is quite a pleasure to tinker with the bike and install different components to test it out and see the effect on the ride quality.

48T is usual for Boardwalk but usually single cranks uses 53T. The common ones are 53T/39T which is enough for me even for Fraser's Hill ride. Most definitely single chainrings are smooth shifting and expect a little chain rub when you mod to dual chain rings especially on the last extreme ratio. The front derailleur cage effectively acts like a chain limiter when installed so chain jumps are rarer. Chain drop might happen if the limiting adjust screws are not properly adjusted. (like the RD, FD also have 2 screws to limit the travel of the cage, inside and outside)

48T means your crank doesn't have the 5 screws holding the crank to the chainring (or 4 screws in the case of mountain bike crank). That means you have to buy another set.

I a bit blurr rclxub.gif since I not familiar with bike. Just a lonely rider only. I will ask the bike shop to quote for the complete setup for the upgrade. I only afraid mechanical stuff you don't touch it is ok. After touch it then weir thing will happen sweat.gif .
