The bike is good, except that the front wheel was a little twisted, which is the option from the staff in my local bicycle store. Other than that, I've used this bike for around 1 week. I only ride it from the parking place to school, 1 mile one way, 2 miles per day. It is smooth, but a little heavy for a lady. It took me a lot energy to put it into / take it out of the trunk every day. But it should not be a problem for guy.
I'm sort of a bike n00b but this is my second folding bike. The other is a 20" Dahon and while the folding mechanism is understandably different, the ride for this bike is much smoother with a lot more "speed" options. It is definitely much heavier than the Dahon but still not too bad. I did find the front tire very hard to align when putting it together. Works great now.
If you consider this just as a mountain bike, it stacks up pretty well against its competition. Dual suspension, quality components from suppliers such as Shimano; it?s tough and built to last, and looks great too. But where this bike really comes into a league of its own is when you consider its incredible folding frame. For so many people, space is at a premium, whether it?s storage space at home, space in the car, or even space on public transport. This bike allows you to keep all the fun of a mountain bike even in tight spaces. KMC Z33 chain, Folded dimensions: L 39" x H 35" x W 23.5", 36 lbs fully assembled. Left shifter: Microshift 3 speed grip shifter, Right Shifter: Microshift 6 speed grip shifter, Front Derailleur: Saigun QD-23a, Rear Derailleur: Shimano RD-TZ50. Brand new.
