Review from guy used to high end mountain bikes (1.8m tall and 90 kilos): The R9 (metal) bike arrived properly packaged. All sensitive areas were covered with foam. Bike came with extra perks like a bike lock (medium to low quality, but still a nice touch), a multitool (same as the lock in terms of quality) and a bell (I love its design). Paint (Titanium color) is really nice, and perfect (no dents nor scratches). Folding areas (hinges) are impeccable. No loose parts nor issues with hinges. Seat is comfortable. The shifters are Shimano as stated in webpage and work GREAT. Breaks do their job as long as you ride at normal pace. If you go full speed, it will NOT bring you a full stop in less than 6 to 7 meters. They seem like good candidates to be replaced in a few months. The rack is included. The handlebar is not cylindrical. Looks semi oval, and this is a BIG problem to attach front lights. Bike weight is 12.2Kg. If you have the money, go for the aluminum one (S9 model). Removing 4kg of weight would be nice. Wheels (CST City Parkour) are OK (I will probably replace them). I LOVE THE FACT THAT THE TUBES COME WITH SCHRADE VALVES. TO SUM UP: for 660 USD (final price delivered to Poland – took literally 10 working days to arrive), this bike is GREAT. If you are “exquisite/picky” in life, probably you will want to replace some parts in the future (lock for seat post), some plastic parts designed to “lock” the bike while folded. BUT STILL I RECOMMEND.
