About Colo Bicycles

As much as we value our customers unique designs, we also value quality. That’s why we assemble and check every Colo Bicycle here in Finland before sending them out to our customers. We have also worked hard gathering up a setup of components that is on par with the looks of our bicycles – a combo that holds up comparison with every same category bicycle in the market.

Frame and fork

All our Colo Bicycle frames are double butted, TIG-welded and made out of quality, 4130 Chromoly steel. Colo Frames come with forged dropouts and integrated chain tensioners. Our framesets are available in three different sizes and six different colors.


High flange Colo Bicycles hubs with sealed bearings. Flip-flop hub in the rear, which gives you the option driving your Colo Bicycle fixed or singlespeed, just by flipping over the back wheel. Our hubs are equipped with 18t freewheel and 18t fixed cog. On our 2-speed bicycle we use Sturmey Archer S2 kickshift hubs, with 22t sprocket


Colo Bicycles crankset, with 46t chainring and 170 mm crank arms


Colo Bicycles are rolling on 700 X 25mm Kenda tires that come in three different colors. Our tires come with Kenda inner tubes and presta valves


Aluminum alloy BMX pedals with removable reflectors. For riders with more sensitive feet, we truly recommend wearing shoes.


Fixie without brakes is surely not for everyone, that’s why all Colo Bicycles are equipped with front and rear brakes. All bikes come with Promax RC 469 dual pivot caliper brakes with Promax brake levers.

Handlebars and stem

All our bikes come with 80mm, 7 degree, forged Ahead stem. For handlebars there is a choice between 500mm riser, 420mm bullhorn and 420mm wide drop bar.


43mm and 25mm deep aluminum alloy rims with CNC-machined braking line. 2-speed option comes only with 25mm rim.

Choosing correct size Colo bicycle

We are offering Colo Bicycles in three different sizes, to assure that you will have correct size frame set and most comfortable ride as possible according to your own size, whether you are under 170cm, over 190cm, or like in many cases, somewhere between.


Our smallest frame size S (52cm), fits best for riders between 163cm and 175cm.


Our most popular frame size M (55,5cm), fits best for riders between 173cm and 185cm.


Our Large (59cm) size frame is ideal for our taller riders, from 185cm onwards.
