Ask a Bicycle Question - Part 5

[THFC78]

Just finished watching ur 4 vid,will try when free,thks ... btw is there a PCN to east coast (East area)

Here you go, video started from crossing the overhead bridge over PIE from bedok pcn

There are some strong riders on foldies. Encik George who is now based in Taiwan, is able to climb and speed up so fast, makes roadies want to throw their bike away.

Honestly speaking as a foldie rider, pick up is faster, turning is smaller and more nimble. Top speed may not match roadie. However with the number of red lights encountered during NTU bike rally, it gives them an advantage as they last longer and a chance to catch up with roadies who kena stopped at lights.

I don't use clipless but I notice the fact they will clip on and slowly push off at lights make them lose a second or two. Long straights is where the roadies shine and the gap widens at places like Lim Chu Kang or Coastal.

What I found amusing is how the mountain bikers were struggling at slopes. I thought their smaller chain rings will give them an edge but I found myself passing them at slopes. This is from a 110+kg bui bui on a steel frame Gios roadie siah

hehe, the slopes not steep & bumpy enough for mountain bikes to have an edge

Wait till you see foldies cycle faster than you, the other day, a Brommie was cycling at 36km/h and trying to cut us while we were cycling back to final stop.
Then again, like wat Snoob said, if you it due to the physics and the smoothness of other things on the bike. Of cos, those riders have been cycling for a long time. Thus easier for them to attain higher speed.

U serious !? That folding "bike"? But how to peddle to fast if their gear isn't that big ? Wouldn't they peddle empty (?)

Wait a veteran on that folding bike....I'm beginning to question my purchase haha

aiya someday, when i get back the borrowed mtb, you can join the edmw sexercise sweat abit road ride

normally this kind of people i let them go in front, they shag then i slowly increase tempo

Lol, looking forward in my flip-flops and singlets XD

That's wat we did, didn't know he was drafting us until I wanted to overtake other riders. Then I shouted bike back. He LLST move to the front and we draft for 1km then overtook him and dropped him. But still gave him a thumbs up when I pass him Not easy to maintain 36 on brommie.

Drafting (?) As in helping him to cut the air first (?)

I know of somebody who completed 168 km on a 18" Birdy. His average speed was about 28-30 kmh.

He has road bike but he said don't need to use it...

You kidding (?) Is he very fit with muscular legs (?)

due to gearing, they can move off faster than a road bike. Acceleration on a mtb will always be faster than a road bike, but once you move off, you lose to a roadie. it doesnt require energy to move off, maintaining it is the killer.

i know cause i used to ride a trek remedy, even drafting at 35kmh along coastal on knobby tyres that weigh 1kg per pair requires a lot of energy and "creative" ways to hide your frontal area.

i got bad luck since my rear sus cannot fully lock, so i require even more energy.

overall just a stupid thing to do, mtb with knobbies are for trail, not to chase roadie.

Knobbies (?)

anyone know if any lbs in the north carries 26" schwalbe land cruiser tires?

any one can help? thanks!

I don't know his configuration for his Brompton. Assuming he got the standard 6 speed with 3spd hub and 2 cogs, with smallest rear cog, crank at 54T, the largest gear inch is 108" or 8.62metres. 60rpm gives about 30km/h.

In comparison, a road bike with 53/14T and 700c wheels will hit 8metres. At 60rpm, is 29km/h; at 80rpm, is 38.6km/h.

Brompton has small wheels. 16inches. But you have to know the gearing is quite different too.

road bike gearing so big? moi 29" hard tail is also 8m / rpm. at max 1 cadence = 3.75 wheel spin

Any folding road bike which Can be brought into public transport to recommend?

Most 20 inch foldies can be brought up. Only difference is how easy/hard to fold and carry.

How about 26" wheel size foldable road bike? Any available models?

but not road bike mtb.

if u buy 26" road bike, good luck finding spares lol

hi anybody wanna order from bike 24 ?? need to get some pedals and some stuff

will close when order hits slightly before 400

Yeah...

He has Birdy, Tern, Brompton and carbon road bikes.

Can't reveal too much, except he's a SAF regular.

Just look at the Brompton gearing..

Quite scary. The only bad thing is the small wheels, which make it harder to roll and coast. I tried the standard chainring size and find it a bit tough to cycle.. Can imagine how tough it will be when chainring size is increased..

And with only six speed in such a big gear range, finding a sweet spot to maintain cadence when encountering different terrain will be tricky.

This person is cycling on a Tern Verge X10 with 451 wheels. His configuration is 56T front with smallest rear cog. So his biggest gear ratio is 56/11 = 5.1.

This is his video cycling with roadies. You can check it out his other videos..

Can imagine how fast he will be if he is using a high end carbon road bike. But then he needs a foldable road bike due to space constraint.
