Question: I am about 5'10". Should I go with the small or large option?
Document: Their products have diminished in quality significantly these past eight years, and their service is lousy - they will not even speak to a customer - you have to go through a bike shop.
Given that it is a folding bike, it is not that easy to design add-on friendly frame. Another annoyance is the seat. It's too small and hard as a rock. I bought some seat cushions but it still feels tiny for the comfort ride - pain around the butt, literally! It is significant issue because this bike is not for hardened Pros - it is built for casual riders.
It folds and unfolds in less than a couple seconds. I can throw it in almost any car's trunk. I was so impressed with it, I bought another one for my wife. We easily fit both bicycles in our small car.The drawbacks to this bike are not big deals to me. First, it has 7 speeds - which some may find annoying, but I find more than capable even with decent inclines. Second, it doesn't have suspension... riding through city potholes can be quite precarious.
I'm an aircraft mechanic so I'm fairly handy. It still took me the better part of an evening to unpack, assemble, and fit this bike using the instructions provided, which don't match the bike too well. I suppose one could always pay a bike shop to handle that chore if necessary. Once I got the bike how I want it, it rides great and folds fairly quickly into a pretty small size. I am sure it would fit easily into any normal car trunk.
I really like the bike, easy to ride and easy to fold up. I highly recommend this for anyone who has a storage problem and I keep mine in the trunk of my car so I will not take up any room in my condo.
Cool bike, but had to return it without opening the box.. got the buyers remorse when it got to my home &#62;.&#60; Anyway, I chose to buy this one because of weight and well, the ability to be folded easily (per you tube video). Its just too dang expensive :/
I love this bike. Easy fold up and good ride. Only thing is that when it arrived, although the box was in good shape, the fork was bent. Had to pay a bike shop to straighten it since sending it back to Amazon would have been too much trouble, especially if they sent another one that was damaged.
I bought this Jack to replace another Dahon, making it my third. I got the Jack because its a full size folder and my previous Dahon seemed less good for rough London roads.All in all its a good bike, except the gearing is a little on the low side for me at about 90 inches.
The price tag (currently $599) is probably on the higher side for this bike. However, if it is not your main concern, this is a nice bike to get and you will enjoy short commutes as well as casual rides alike. I was tempted to give it 5 stars; however, it looses a star because of its price to performance ratio.
To make matters worse, it turns out that the company no longer carries parts for it - a bike they sold only a year-and-a-half before! So still wanting a folder, I looked up the Dahon Jack and saw that it actually uses the older type of folding mechanism, but is only a 7-speed as opposed to the Matrix 24-speed gears (and yet costs $500).
Answer: no
