Merging of data overlays with sports action camera video

I went for a quick 30 mins ride on Saturday and decided to record my ride using my old trusty Garmin Edge 200 and a SJ4000. Merging of the 10 mins segments into one video was done using windows live movie maker and the data overlay was done using the garmin virb programme . In total it took around 6 hours or so to transfer the data onto my computer, and to upload it to YouTube(without edits), which isn’t very ideal in the fast paced world of today. The data was slightly out in the video as I started the Edge 200 after one full round.

Raleigh MV8 Review

All along, I had a certain fascination on mini velo, they look really small and are designed to go longer distance as opposed to a BMX. To put it simply, they are in my best description described as non fold-able folding bicycles. My interest in the MV8 waned or increased depending on how much I looked at it. Just recently, I started work in Central Singapore and thought about commuting by bicycle as it was faster, and a great way to get a workout. Working in an industrial area made it crazy to ride my merida to work and my thoughts went back to the MV8. Managed to get it and as of now, I done roughly a day’s worth of commute roughly 30km shuttling back and forth places.


The MV8 costs roughly the price of the wheelset on my Merida (Fulcurm Racing Quattro) To be honest, I did not expect much from the bike, given the cost of it, but still I am pleased at the package offered by Raleigh. They skimmed on certain parts but to me, the highlight of the bike is that they somehow managed to spec a branded (Shimano Claris) rear derailleur.

The Build
I wanted a dropbar version of the bike due to the variety of holding postions avaliable on the bar. I stripped my old road bike and transferred the cockpit as well as the saddle(which gives me the option to mount the fizik saddle lights. After a few hours of tinkering in the bike shop, the final product came out well, to my expectations.

Frame and Fork
I was surprised to find that the frame came with internal cable routing,a feature that is found instead on most of the road bikes on the market nowadays instead on a S$400 bike. I accdentally pulled out the whole cable and housing while re cabling to the tiagra shifters, putting everything back though was a hassle and best done by a bike shop. The frame and fork offers a variety of mounting points should you decide to upgrade. For brakes it offers, V brake, Disc Brake(edit: was advised that the mounting points are actually for fenders) and Caliper brakes. It offers a variety of mounting points for fenders and racks as well. The bike however has a pretty standard geometry, ( I only measured the top tube which was roughly 52cm) it is relatively long compared to its wheels. It’s wheelbase is super long compared to other bikes that I ridden and it gives a very cushy feel. Huge rear triangle is not very stiff coupled with the seat tube gives it a very comfortable ride.

The bike was speced with a promax (no model number could be found) V brakes, To me, the overly shiny calipers looked cheap to me, but they do their job just fine. Fitting them to work with a road shifters posed no issues though I needed to squeeze the brake calipers more to get more braking power

Seatpost and seat clamp
The seatpost are promax branded. They are good value and are surprisingly easy to adjust.It is a one bolt design with the cradle seating on the seatpost and a clamp goes over it. To adjust just shift the cradle up and down and it is done! Simple and easy to adjust.

I swapped the stock seat clamp which was using a lever to a seat clamp that uses a bolt to clamp the seatpost as I do not want it to drop due to lack of grip (which happens often to seat clamp that uses a adjustable lever)

Drive train
The drive train consists of a KMC Z72 chain, Promax square taper crank(with a chain guard), mated to a Shimano Claris rear Derailleur and a epoch hyperwave 11-25 cassette. I swapped the cassette out as I prefer using a name brand cassette and though it looked shiny(and cheap), I would rather use my old PG850.
I like that they spec the rather new Shimano Claris rear derailleur. The shifting isn’t exactly the best with the old shifters but the bike is too new to tell if its cable adjustment or equipment mismatch or just poor tuning.

The ProMax is not exactly the best crank out there, I could feel it flexing when I mashed it really hard. The chainguard is there to prevent the chain from falling off, but if the derailleur is properly tuned, such incidents should not happen. It looks abit flimsy, but then again the bike doesnt costs alot of money!

Wheels and Tires
The bike came with Innova Tires and Quando wheels. The tires are rather comfortable due to its width. The wheels however are is a big let down. Wheels are a let down in my opinion. Wheels are supposed to be relatively true out of the box and smoothness of the bearings is a secondary issue. This wheels, however are not true and the bearings feel rough. The bearings feel is very noticeable, particularly at high speeds (over 30kph) and the wheel was untrue enough that brake rub was very noticeable even when the v brakes are calibrated. The hubs looks shiny, but it doesnt perform as it is supposed to look like.

While the hub reads. “Quando, High Performance Hub” It definitely doesn’t feel high performance to me.

This is my first foray into the world of mini velo but despite the drawbacks, I am still quite happy at the purchase. One shouldn’t purchase the bike thinking that it will perform like a S$1K bike, and it isn’t. The frame offers great upgrading options should you choose not to use their stock parts. If Raleigh is able to offer their frames separately, that will be good (around the 150-250 price point will be good) I am considering future upgrades to improve the flaws. For now, I just have to wait for the magical item that makes the world go round to regenerate.

Reasons to buy the MV8

  • Compared to its even cheaper brother the MV7, the mv8 comes with a freehub which offers a relative cheap upgrade path to 9,10 speeds if one has enough spare parts from other bikes.
  • Frame has variety of mounting points for different types of brakes and additions like rack and fenders.
  • Relatively long frame means that it is stable.
  • Fat wheels means that potholes and drain covers have no problems.
  • V brakes offer relatively strong braking power, good for those who are new.

Reasons to not buy the MV8

  • Wheels are not exactly the best, it might be a Quality control issue
  • Square taper cranks are hard to install and remove
  • Fat wheels are not meant for people who want to go fast

Full Specification as reviewed

Suggestions for a key cycling Route-Bishan To Gardens by the Bay

Recently, Straits Times reported that URA is conducting a study on making the Bishan-Kallang Park Connector a seamless route. If the study is successful, it could pave the way for other similar “commute” route for cyclists and runners who wish to commute other ways. besides public or private transport. I applaud the idea, as it could be a way for cyclists who are afraid of the road to commute safely to work without incident.

The Park connector network was originally conceived as a walkway/path to connect to all the parks all over Singapore. Commuting was never thought out of as it concentrated mainly on making parks easily accessible via jogging or cycling.  The material of choice for the connector varied within park connectors (most are using tarmac now but there are places like Siglap park connector which uses bricks for some part of the connector) Commuting was thought of as impractical (due to the hot weather) or the government had confidence in the current transportation system and saw no need for a walk/cycling commute.  Thus, there wasn’t a need for no grade crossing or relatively wide path for people to use.

The PCN idea is able to evolve further, into a park connector which has no grade crossing across roads with exits and entrances for park users, which is similar to the idea used in Amsterdam.

Special Thanks to bicycledutch.files.wordpress
This can be done via a combination of tunnels and bridges. Tests could be done to see if the grade of the bridges is gentle enough for cyclists to cross without falling off while riding. Curved bridges could also be employed if there is insufficient places  to construct a straight bridges or tunnels.

While the ideas of scholars are refreshing and insightful, I hope that the government could ask ordinary people (the ones who actually use the route) to give feedback on not only the bridges used, but also the width of the pathways. What works in theory may not work as well as in practice, thus I personally feel that users must be included in the pilot study and not people who wear suit and ties who drives to work without knowing what is going on the ground.

Lastly, I hope that by building the route, I hope that the government doesn’t force all cyclists off the road and onto park connectors, while park connectors were originally conceived as an connectors of parks,  there may be cyclists who choose to use the roads instead as it is faster or lack access to a park connector.

Review: Fizik Tri Gel Pad

Aerobars often come stock with cloth elbow padding, which may suit some people. For me, I do not like to use cloth based padding, as they will stink under Singapore Humid weather and they come out easy after the cloth padding starts to give way.

Enter Fizik with their revolutionary “Technogel™” elbow pads. According to Chain Reaction Cycle description of it “Technogel™ won’t harden, lead, break down or migrate. When pressed, TechnogelTM moulds itself to the individual’s shape, by deforming 3-dimensionally along horizontal, vertical and diagonal axis.” According to the description, I purchased it as I thought it will be a viable long term solution to solving the cloth pad dropping out after awhile. It comes in a variety of shapes and sizes to suit a variety of aerobars.

Long term review
When I purchased it some time back from Bike 24, I still had my vision aero bars. The pads looked cool and  you can also cut it to suit the shape of your elbow, which I did not find a need to.

The Good
What I particularly like about them is that the pads are not that thick and do not deform when elbow pressure is applied to them, this flat yet comfortable base might take a little to get used to but it is good. They also do not seem to need washing as it does not stink at all, compared to cloth pads which may  need some washing after some usage.

About a year later, I switched to 3T clips on and the vision shaped pads still fit well !

I find it cool that you do not need to install/epoxy new stuff to install these baby on, simply rip out your old cloth pads and install these on!

The Bad
Unfortunately, Technogel™, while sounding futuristic and cool does degrade after some time. First it turns yellow probably due to the exposure to UV rays from the Sun, before turning into a sticky, messy gooey pads that is quite disgusting to rest on, I have ripped the left pad out simply from the adhesive strength from the sticky residue.

End of the day, I still re-purchased the pads. They are comfortable to ride in and do not stink which is the main reason I purchased it. It is no maintenance at all, no cleaning or whatsoever till it decides to turn sticky. On CRC, they are priced cheaper than some cloth pads which make it a bargain. Still, I do not mind the stickiness, as it means washing one less bike component. If Fizik is able to make it un-degradable, they could have a product that is the best aftermarket pads out there. For a relatively low-tech product, I am surprised at the innovation Fizik has thought out when coming out with this pads. I have tried rotating the bike so that the elbow pads will have minimal exposure to the sunlight when its parked at home, hope the pads can last longer.

Do not need Washing

Warning! It degrades under regular exposure to sunlight
Sticky residue might make you think twice about riding the elbow pads

The 2x Elbow pad set was paid for using the author’s money with no discount other than the price listed on the sites.

Review : Bryton Rider 20

Bryton is a Taiwanese company that manufactures Sport GPS devices for athletes and consumers. A few of my team mates are running the Bryton rider 40, while I was previously running the Garmin Edge 200. I was looking for a cycle computer to replace my Garmin as I wanted more data; I wanted to know my cadence, and heart rate.  Upon surfing the internet at my usual online cycling store(bike 24), I chanced upon the Bryton 20 on sale and purchased it as the Eur rate made it pretty cheap.

Why not other brands?
My requirements for the new computer are

  • GPS
  • Cadence, Heart Rate compatible
  • Ability to upload data online

My initial choice was to go back to Garmin by upgrading to the edge 500, but it costs 2x the price of the Bryton, which made it pretty unattractive. The Polar CS 500 (which I am pretty familiar with as I used a Polar CS100 for about 2 years)  came in a close second, but upon reading that it requires a dongle to upload, I was turned off by it. I thought of the Cateye stealth series as well, but online searches about uploading data was sketchy at best.

When comparing  GPS enabled cycle computers, I feel that it is always good to compare it with the Garmin Edge series. Their computers are user-friendly and their tracking software are easy to use as well (albeit with minor bugs) On to physical comparison.

The Bryton is much smaller than the Edge 200 both in terms of size, and as well as the weight. I am quite impressed with how small it looks, in fact it could pose off as a typical “cateye” kind of cycle computer. This means it looks pretty small and discreet on the stem, rather than their bulkier cousin.

One thing that I like about the Edge 200 is that the rear USB plug is shielded from the elements by a nice fitting rubber plug. No such feature, on the Bryton Rider, instead, it uses a proprietary 4 pin system on the back (I suppose 2 is for the Power, and the other 2 is for the usb) My long-term experience is that it tends to collect dirt and that power and data transfer is impossible without cleaning up the golden female pin.

I hope that Bryton will implement a standard usb design (such as the micro usb or the mini usb) so that users will be able to use other usb cables should they lose their cables.

FEATURES- Computer
The Byrton Rider 20, uses a 3 button system, while the Garmin uses a 4 button system. The big blue button is used to acess the menu, while the other 2 are for scrolling (note that the upward facing button is for scrolling the upper half which contains, time, Total time for ride, current, max, average cadence. Downward facing button is for scrolling the lower  half which contains distance, calories burnt, odometer distance and time, and current, average, maximum heart rate)

The other unique feature not found in the edge 200 that is found here is the link up to your ant+ speed/cadence sensor as well as to your heart rate montior. The sensors used need not be from bryton but rather any ant+ compatible sensor. I am currently using the garmin gsc 10 speed/cadence sensor as well as the bryton heart rate montior. Other than a slight delay in recording the speed and cadence, the combo has worked flawlessly so far.

A pecularity of the Rider 20 is that the cycle computer somehow does not operate while it is charging, so if you have to do a ultra long distance riding, you might want to consider a garmin instead for that extra long one day long ride that you have.

Features- Bryton Sports While you can choose to upload your files to your training programme of choice, Bryton has provided a rather simple programme called bryton sports

It is rather simple to use just plug your device in and use download bryton bridge, and you can download all your files from your cycle computer into the bryton data centre.

The Bryton is very nicely priced, being signficantly cheaper than its direct competitor. However, due to it being rather a new player into the market, the product does have its drawback which can be ironed out in the next update (I highly doubt the durability of the golden pins in the long run.) At that price range, none of the competitors in the market is able to provide such features. In short, it is a fun-sized cycle computer that will be able to function anywhere (including tunnels) while tracking your data at the same time.


  • Cheap
  • Speed,Cadence, Heart Rate compatible


  • Funny USB interface
  • No usage of device while charging

This product was paid for using my own money and as at time of writing still sitting on my table. Any factual/ spelling errors on the article is concidental due to it being typed at 1155pm in the night, and I will seek to correct any errors made.

Road to a faster me

I am back, after 2 months  of not riding or so due to examinations. As my school term winds to a close. I find myself picking up my favorite sport again.

Started Day 1 with a 30 min spin around my neighborhood on my TT bike. Wanted to go for an hour, but felt nauseous.

Needed to change the pads, since they degraded by turning into a sticky residue due to UV exposure I think

Day 2 of training started with a group ride with my usual group. Got dropped on the last 4km, Heart Rate spiked up way higher, and the nauseous feeling was back, at least I managed to hang on for 90% of the way

NTU bike rally, 2015 edition!

Back again for the 2015 edition of NTU bike rally, I skipped the event for 2 years and am back again as I plan to improve my fitness again. It happened on 8th March 2015, and due to some school related matters, I am not able to sufficiently high mileage in to be considered in optimum form. Moreover, due to some unforeseen circumstances(Non Drive Side Retaining bolt dropped off), I was forced to train for 2 weeks in my spare bike, a 11kg road 8 speed road bike. Fortunately, I managed to get my Merida Reacto back 2 days before the event and well more about it below.

About NTU Bike Rally
The thing that separates Bike Rally apart from the other organized events is that it is a student-initiative operated by the NTU sports Club. This gives newbies(Mostly NTU students from what I observed) a chance to ride in an organized ride on the road escorted by either safety car or marshall. For the ordinary cyclists, it means two things 1. Cheap prices as it is from a not-for-profit organization 2. Long Distances. This year, route on offer are the 168km event as well as the less-daunting 88km. It makes the event a bargain compared to the other cycling events organized in Singapore. Then again, this event is a non-timed event with no price money for first,second,third so perhaps that’s the reason why prices are lowered.

I signed up for the event under my brother’s name(who is a NTU student) thus, it costs merely 20SGD for the ride, and perhaps breaking a few clauses of the ride. I added the Jersey for an extra 45 sgd and it looks amazing for the price.

I had relatively little sleep before the event as I came home late.

Woke up at 5, had breakfast and slowly made my way to the F1 pit building. There wasn’t that many people when I arrived, checked in promptly and then went to chit chat till the event started at around 630

Flag off and Getting Lost
The flag off was not very fast, quickly made my way to the front to get draft from the safety car which wasn’t traveling very fast. It was still dangerous and had to do sudden braking as we went meandered around the CBD area till Bukit Merah area. It was all slow and happy till we reached the first “rest” point at West Coast park. Several in my group asked where the rest point was, but the marshal indicated for us to go forth, after seeing my distance (roughly 12km) and having read the ride map (which indicated next rest point was 17km away) a couple of us decided to press on.

The speed suddenly increased dramatically to the 40s kph without the safety car, and the group was left with around 15-20 riders, mostly people from the west coast riders. We didnt have an idea where the next rest point was but I figured that it was at raffles Marina (same as the year I last participated in) There wasn’t that many signalers to indicate where we are supposed to go, but I noticed little yellow A4 Signs on Lampposts indicating where we are supposed to go. (Good idea by them) Reached Raffles Marina early, almost missing it as there was ongoing construction work and stopped for some well needed isotonic drinks, water and some bananas.

On The Verge of Bonking
Safety car finally came, and off we go, this time headed for NTU, met with my friend B(a friend on the sometimes I will be there 6 am ride), and we stuck to the front while catching up with each other. Took some photos, and almost fell off due to a pothole along Pioneer road. The speed/cadence sensor decided its a convenient time to die, and it failed to revert back to the GPS signal. Saved the ride data, and started a new one. Data up till that time is here.

Soon came the NTU climb up and god it was tough, compared to the previous 50km of straight road. Managed to stick somewhat close to the car, and was rewarded with red bull, and water at the rest point. Soon, it was time to go again, and off we went, this time to woodlands promenade.

We went pass Mandai at a somewhat crazy speed, and off we go to Gambas Avenue, it was then I felt that I was going to bonk soon, the feeling that my body is not sweating and felt that I was going to give my last shot at riding. I bonked pretty badly around 2km away from Woodlands Promenade, felt like I was on fire, signs of nausea and headache. Decided to take a break, cool off and consume more food and drinks. Rested for awhile with a self-made Ice pack and chatted with the crew and other cyclists. I must say the stop was excellent with helpful student volunteers who gave food, ice and drinks to cyclists who really needed them.That day was exceptionally hot.  The heat was getting to me, and that wasnt the last time it got tome.

New Friends last together all the way!
After resting, I didn’t have any cars to draft, so I went off at the same time as other cyclists, hoping to draft them. I met 2 NTU students who was participating in the event as well A and T. Off we went together as a Trio, catching up with other cyclists. Passed through all the pit stops together (one at Punggol Waterfront and the other at Changi Beach) I bonked again shortly before reaching Changi Beach and we decided to take a short break there.  Sadly, I forgotten to charge my Bryton (though I left the house with 3/3 bars on the battery) and it died shortly before reaching Changi Beach.

We rested for a short while before riding all the way back to the Starting/Ending point at the F1 Pit building. Journey back was a bliss with a tailwind along Changi Coast road, and light traffic along Nicoll Highway. Noticed some people from the running hour group with their tandems. A great initiative to let the blind ride alongside the able for the ride! Finally done with the event at 2pm and after resting, headed home for some well needed rest.

The day was exceptionally hot coupled with lack of training made this event a painfully one for me. However, I was rewarded with some new friends, and the enthusiasm of the NTU crew gave me the strength to carry on riding. In conclusion, the bike rally, is a fun long distance ride that reminds me that cycling isn’t all about racing and training, anyone can do it as long as they try!

Finally some pictures.

My friend/Nemesis for most of the journey. Despite the bike rack over it, the car is still aerodynamic and I didnt feel much draft from it.


Somewhere along Jalan Buroh, going very fast

Hanging on to the back along Lim Chu Kang Road.

End point, just after lunch time.

Data for the last 100km is here. unfortunately, I forgotten to charge and the last 30-40km of the journey is not recorded.
