I took a little time to go through some of the archived threads, and I found this one. The OP was asking a question about the Qile Duo brand of folding bikes. OK, so this thread is almost a year old, and the probabilities of the OP, and the counter poster reading my reply, are slim to none. However, since I do own one of the models from the brand in question, I felt I should chim in, and give my personal impressions.
My humble opinion about commenting on other brands, is that you don't unless you have personal experience with the product in question, or know someone who has, and you've been able to get that person's candid impressions about it. No offense meant towards the counter poster.
My experience with the VSTII (Model # of my bike) has been very satisfactory to date. It is best described as a 20", 5 speed, rear suspended folding bicycle. It comes with full fenders, and a rear cargo rack.
I bought it through eBay (Any surprise with that?) back in early May 2008 from a vendor based here in Florida. It arrived in perfect condition, and virtually no assembly was necessary. Alright, there are some caveats. First of all, the rear band brake can be "tricky" to properly adjust right. A bike shop mechanic is one's best bet, but no all of them know how to do it.
I took this bike to one of my favorite bike shops where I had them go through it from end to end, grease all the bearings, the joints, and perform a complete tuneup. They did a wonderful job. I've had no major issues at all.
Next was to lose the "knobbie" type tires as they created too much drag, and change out the saddle to something more comfortable. These two upgrades are done very commonly by buyers of mid to high end folders anyway, so it's not a reflection of the bike's overall quality. For tires, I got a pair of 20" x 1.95" Kenda "Kontacts", and the saddle was switched out for a MTB type from "Bell". Two weeks after that, I bought new hand grips from Bell that were much more ergonomically correct. So far, so good.
I equipped my bike for commuting as I was anticipating to let go of my car which I did in late October. But I've ridden it for pleasure, as much as for necessity, and it has held up perfectly well. For the last 2 1/2 months of 2008, I've used it to commute to work 5 miles each way.
I worked for a company in Downtown Orlando, and for some reason, the city planners think it's so neat to go back to the era where brick streets was "state of the art". Well the brick layers didn't do a good job, and this translates into a rough ride. But the robust frame, strong 20" wheels, and the rear suspension on my Qile Duo would laugh at this stuff.
If one were to equate my VSTII with a "department store" bike in terms of quality, then according to this "wisdom", it should have fallen apart more than 1,000 miles ago! So that takes care of that assumption!
The other side of the coin is that yes, it is heavier than more expensive brands. No it's not the first choice for a cross country tour, and cruising at speeds above 17 mph can get laborious, but one would be missing the point of this bike, which is a low cost, reliable, and ruggedly built folding bike for daily use.
Qile Duo does offer several models that are better suited than mine for higher performance levels, better componentry, etc. So to discount that brand as a "department store" bike is way off. They also have another brand called "K-Rock". From what I've read, the factory is compliant with the requirements for the ISO 9001:2000 for international quality management standards.
I don't own any part of that company so that is not the reason for this counter post. It's a good bike...that's all.
