Great Bike!

I've been riding this bike for a little over a year now and absolutely no complaints! It's really light and easy for me to carry up two flights of stairs to my apartment and has even been sturdy enough to handle my silly crashes from reckless riding. Would highly recommend to anyone looking to start out riding fixed.

Nice bike!

it's a good, simple and actually very fast bike, would recommend as a first fixed gear!

Would buy again!

Light weight, good looking, a pleasure to ride, and excellent value for money. Can't think of a better deal at this price! Would possibly recommend changing the pedals and saddle for slightly better comfort, but these are minor things and more personal preference than anything else. Five out of five!

Simply Great

Got this as my first step into the fixie world and it's not disappointed. Have had to get different pedals and straps simply for comfort while riding. Overall; love the bike, very happy.

Very stiff

i bought this bike a few months ago for training but after a few weeks i decides that i could use this bike for racing if i felt like it. the bike is very stiff so all the power is used efficiently.The packaging of the bike was done very well and it arrieved quickly.
