Review of the Dahon Speed D7

1 comments
It has seen it all...



Being my first 'real' folder, the Dahon Speed D7 (2008) has been with me ever since I started bike commuting back in 2009. It has seen it all - from riding in the rain to riding in Taiwan. It has been modified, been crashed into, been in minor accidents and is basically what you'd expect from something that has seen 3,000km worth of roads in many different situations - from commuting, to leisure riding, to touring. To be more accurate, I'd say it has done about 2,300km worth of commuting, 150km of leisure riding and 550km of touring.

When I bought it in 2009, it was the cheapest Dahon at $650, and with that money, you get a folding bike with a very natural upright geometry, a good gearing range (34" to 91"), and entry-level equipment that works well. Mine came with Kenda Kwests, brand-name V-brakes... nothing special. Unlike the American versions, however, Dahons don't come with fenders and an ArcLite rack as stock, so don't be fooled by the pictures on the Dahon website...

Performance

When I first bought the bike, having upgraded from another folding bike which shall not be named, it felt like I've hit jackpot. My previous folding bike was cramped, had rubbish gearing meant for 26" bikes and thus had a very low gear ratio at the high-end (~65") which meant that going over 25km/h was just impossible. The Dahon, on the other hand, had a great geometry that is comfortable, and it had a wheelbase that makes the bike less twitchy - a characteristic inherent in small wheeled bike. Best of all, it had quality tyres - the Kenda Kwest, which is a tyre that I feel gives great bang for buck, and... the gearing allowed me to hit 40km/h when necessary.

All was well and beautiful in Singapore, where even the steepest and most tiresome hills don't last for long, or had tolerable grades. No hill lasted more than 15 minutes, which was a good thing because the gearing on this bike was quite poor when it came to climbing. Starting at 34" - which felt a bit like the lowest gearing on a road bike, it was a bit of a pain to ride up grades steeper than 4%, especially when you had a load on it. When I took it to Taiwan, I totally wanted to throw the bike off the cliff in one of its many 7% mountains that can last for around six hours. In the end, I was walking half the time, and it came to my realisation that the gearing just isn't meant for anything but flat and lightly steeped terrain.

But let's talk about things more pertinent to daily use, rather than esoteric extremes. Commuting with the bike is great because you'll be sitting upright, so you'll be able to get a better field of view, and turning to look backwards won't affect your balance as it would on a road bike as most of your weight is perched on the saddle, rather than on the brakehoods as you would be on a road bike. The brakes are moderately good - it won't beat discs anytime, but it does brake adequately well whether in the wet or dry.

Unfortunately, for people looking for a fast ride, a road bike is still the best bet. Due to its upright position, it does suffer from significant drag that will slow you down - I tested it going down a 8% decline over 2km, and I managed to reach a terminal speed of 45km/h. Its lack of close discrete gearing also makes it hard to eke out maximum performance and optimal cadence, every gear change produces a distinctly palpable change in cadence.

Folding

In no way would I say that this bike folds very compactly to the extent that it's convenient to lug around. No, it's a 12.5kg beast that folds to something like 30 x 77 x 64 cm. Large. And heavy. It's around 33% larger than the fold of a Brompton.

Folding the Speed D7 isn't too hard, you just have to fold it vertically, then horizontally. Do the seat post, and then the handlebar post, then do the frame and pedals. Done. It gets a bit more complex when you have a touring rack on it, as you'll need to rotate the handlebars such that the brake levers don't come into contact with the massive touring rack.


I actually bought the Dahon because I had a few of my bikes stolen before, and thought that it would be great if I could take the bike with me whenever I go shopping. How wrong I was. In addition to the thousand stares that I got every time I lugged the beast with me, it was also heavy and unwieldy in cramped areas. Though I haven't had any shops stop me from taking it inside. But what I have proven that it is possible if you want to have a bike 'by your side' all the time, though there's a price of convenience to pay.

If you're thinking of taking the bike out, let me just say that it won't fit in that VW Polo's boot, though the Honda Fit manages it quite well. And trains... yes, Singaporean trains do accommodate these bikes well, though prepare for a thousand stares.


A First Bike?
Absolutely! I'd recommend this bike for people who are impoverished but are looking to get a quality bike for various styles of riding. The fact that i have done so many things with it is a testament to how it can grow with your varying interests in cycling, though... not very well at some. Commuting with it in Singapore is fine and dandy, because we're pretty flat, and if you're trying to get thunder thighs, all the better this is - because it lacks adequate gearing for you to spin comfortably when faced with 7% hills.

The ability to fold is also a big plus for everyone, especially people new to cycling and haven't necessarily got the skills to do road side repairs. Punctures and drivetrain problems can now be easily fixed - call a taxi and get to your nearest bike shop!

Schwalbe Big Apple Review

Schwalbe Big Apple HS 338 Fatty Bicycle Tire (20x2.0, Allround Wire Beaded, Reflex)

I'm gonna write about my experience with the Schwalbe Big Apple, since I have to forgo my weekends riding, I might as well revel in another activity which I like - writing about cycling. The Big Apple is a pretty fat tyre that's touted by Schwable as a "balloon" tyre, and it has the highest-end tyre protection, the Smartguard.

I have put around 600km of use into these tyres through mostly road, but also on gravel and in the wet. My opinion of the tyre is mixed. On one hand, it's a great, comfy tyre for bikes which do not have the luxury of having suspension, on the other, it's an effort killer!

Before I took these tyres touring, I used to ride the bike in the city. Immediately after changing them from Schwalbe Kojaks, I found that these tyres almost sapped me of 5km/h of speed! The reviews that I read showed that they were quite fast, but that was contrary to what I felt. I completely felt that it was so slow! The biggest indication was my speedometer - I could only keep a speed of about 20km/h, and that was quite a far cry from the 25km/h which I used to do. Of course, more critically, my maximum speed dropped to 32 - 35km/h instead of 40km/h.

Nonetheless, I still decided to take it to tour, and after the tour, I am ambivalent on this tyre. On one hand it's slow and can be frustrating when you need to travel long distances, on the other hand, it is great for Taiwanese roads which were terrrrrrrrrible. In Singapore, you probably don't need such a comfortable tyres because our roads are excellent and don't have so many uneven spots or potholes. However, one characteristic that I'm quite appreciative of is its traction. This tyre has traction that is perfect for wet downhills. When doing looooooooong downhills, I had traction to do a lot lane-wide corners at 40 - 45km/h.

The 2.0 width of the tyre also means that it has a lot of ability to tolerate lesser roads such as roads littered with gravel, packed mud singletracks and cobblestones. Within limits, you could take a bike with these tyres to light off-road areas, as I did when I was going downhill on one of the mountains in Taiwan. There were roadworks being done throughout the whole road - it was gravel all the way, but with these tyres, it wasn't a problem. With Kojaks or tyres of that kind of size, I suspect I'll have a big problem with traction as the tyre would be busy kicking stones around and the 90psi tyre would be digging a hole.

Its puncture protection... supposedly to be the best among all Schwalbe liners, but take a look!


Unplattbarr... not!
Bad luck? Probably. Or maybe I shouldn't have ridden over areas littered with crap. Oh well, that's the bane of cycling, you have to keep right as possible without obstructing cars. Nonetheless, taking the tyre out was easy because the bead isn't as stiff as the Kojak's. You could practically mount it without any tools!

Alright, I guess you guys would wanna read some of my personal opinions on some stuff that I use. Personally, I have a few tyres, bikes and saddles that I would like to share with you. If you've read an older post, I bought the Rido R2 saddle specifically for the Taiwan tour which I did last week. Here's what I think of it after this 550km worth of riding.
