1) As a tall guy, where you comfortable with it?
I'm very comfortable with the current configuration of my bike. I have a headset extender, and that allows me to configure the bars higher than the saddle (great for touring). I have the large size of the model, which helps, as it comes with a longer head-tube etc. The drop-down handle bars are a big bonus, as is the brooks saddle.
2) Is it possible to do long distance?
It's very possible to ride long distances. With an oversized chainring in the front (54 / 56 teeth) I'm almost as fast as on my road / track bikes. My longest days were in excess of 200kms, fully loaded.
3) What was your gearing ratio?
I don't recall my gearing ratio at the moment
4) Were you having fun? or How was the experience of riding?
The riding experience is very fun! The look of my bike is sort of industrial-utilitarian. I appreciate how much cargo the bike can support, and when I'm on grocery runs, I really value the clearance between the handlebars and the wheels (no shopping bags are ever going to get stuck here).
The bike also has a ton of character. People are really intrigued by the design and configuration.
I also ride with relatively fat tires (schwalbe big-apple in the front, and schwalbe marathon in the back), so the road-feel is very comfortable.
5) How is this riding experience compared to a normal road 700C?
See #4
6) Why a Mini Velo for you?
-I like the design of mini-velos
-since I'm tall and weigh around 200lbs, I wanted a more rigid frame than a conventional mono-tube folder offers. With a top and bottom tube, the ride is appreciably less noodly.
-I travel relatively frequently (I live and work in Shanghai, but travel within Asia) and wanted something that could be easily transported on the airplane. My bike is separable, and when broken down almost fits in a regulation sized suitcase. I've never had to check it as over-sized.
7) How about the maintenance cost compared to a normal bike?
The maintenance cost is identical, if a bit cheaper than a normal bike. 20" wheels are generally about half the price of 700s. Also, since I'm living in China, the cost of bike repair is about a fifth of what you'd pay in the states.
8) If you had to choose between a Road Bike and Mini Velo, what would you chose and why?
I would choose my Mini-Velo hands down (though my bike has many more functionalities than the bikes-direct mini-velo / the soma minivelo etc).
For me, a bicycle should always be measured first by its functionality. I can't imagine a more functional bike, or identify where its functionality could be improved:
The geometry is comfortable and configurable
20" tubes are universally available
The gearing is fast when necessary, and easy with hills
I have the option of fully loading the front and the back
It fits in a suit-case
The drop bars are ergonomic
It looks extremely unique
That being said, my bike is a rare breed, and no longer produced by dahon (though there are similar product lines if you do a bit of digging). Mosty of these advantages don't apply to the mini-velo you brought up in the thread.
9) What's your daily bike even at home?
This is my daily bike (I regularly commute 30+kms with it) but I sometimes use a factory five track bike for riding in the city (the geometry is a bit more aggressive)
10) What's your thought on the 20" Wheel compared to a 26 or 29er?
I wouldn't ride a rugged mountain course on 20", but for every other application they're more than adequate.
11) Where you able to match the same comfort and experience of a normal road bike?
Yes
12) In one day how much miles or km your were doing with the mini velo?
During my tour, 125 kms / day. In Shanghai, it depends purely on my schedule (an average of 15 or so)
13) How was your ride during tough weather conditions and hilly roads?
Tedious, but I don't think that had anything to do with the bike!
