Are fixed gear bikes dangerous?

Fixed gear bikes are no more dangerous than traditional road bikes if you ride within your control limit. Fixed gear bikes can take twice the distance to stop as a traditional bike since they don't have breaks. This means you have to be more aware and quicker to react when riding a fixie versus a road bike.

How do I choose the right fixed gear bike geometry?

Fixed gear bikes are based on track bikes and thus the main three geometries to choose from are track, road and cross frames. Track fixies offer a stiffer ride with the quickest maneuvering and handling. These types are preferred by die-hard fixie fans and former racers and are not ideal for more mellow riders. Road geometries are ideal for new users with a less compact frame than track bikes and smoother control. Cross frames are slightly longer and provide more stability.

How do I choose the correct size for a fixed gear bike?

For the best control maneuvering you should choose a fixie that is one size down from your regular bike size. So if you ride a 57 normally then you should go for a 55 in a fixed gear bike. To find the correct size, measure your inseam in centimeters, which is the length from your crotch area to the floor. Multiply this measurement by 0.67 and round to the nearest whole number. This gives you the number of the bike size you need.
