How fast do fixed gears go

That humungous serving plate-size chainring then goes to work to propel you forward at speeds your Huffy would never even dare to dream of. That monster of a chainring sports teeth and is 17 inches in diameter. That means every go-round of the pedal sends the bike forward way farther than your standard road or mountain bike.

According to NPR , the bike has already reached speeds of 60 mph on the open road, but creator Tom Donhou would like to get it up to mph. Getting there under pure leg power alone is a little out of reach, which is why many speedster bicyclists use a lead vehicle that provides a good draft to follow in. That's how Donhou plans to get up to speed with this unusual bike. The Donhou mph bike won't be breaking any speed records, but it does manage to look much more like a regular bike than most of the specially designed creations that have set records.

That chainring is certainly an attention-getter. The bike was unveiled at the Bespoked Bristol show, but so far it looks like it will remain an specialty item and not go into wider production. The larger the number of patches, the more evenly the bicycle tire wears, and the longer it lasts. We can use one of many calculators available on the internet to calculate this value and analyze the ratio and cadence. When choosing the optimal ratio, we have to consider several factors, such as personal preference, leg strength, or elevation of terrain.

If we live in hilly places, too low a gear ratio will mean that our legs will move at the speed of light everytime we ride downhill, which is an accident waiting to happen. Especially if we're using SPD pedals or straps read more about this in another of our articles. However, if the ratio is too bigh we'll probably have to get off our bike halfway up the hill and push it. For flat places, a ratio of 2. This is what we install as standard on our bikes. However, if you need another ratio, let us know.

We'll easily change this parameter for you. Starting from a middle value will be the simplest way to find out our needs. After riding for some time, we'll be able to decide whether the ratio is right for us or whether we need a higher or lower value. The replacement of the rear cog is enough. The gear ratio that you decide on for your fixed gear is a very personal thing, and the value of this parameter will be different for every rider. If you're only at the beginning of this journey, it's best to experiment or go to a bike workshop and ask for help in choosing the right ratio.

Remember also that preferences will change with the development of muscle mass and fitness for each person. Are you interested in the idea of owning a very nice fixed gear, or are you looking for a fast, versatile bike for the city?

Check out our latest range here. Since , we have built several hundred personalized bikes, and we can safely say that we know quite a bit about it. As part of the blog, we want to share this knowledge and infect you with our passion for bikes. You will find numerous tips here, as well as articles on cycling culture and history.

This means that when you stop pedalling on a single speed bike, the back wheel will continue to turn but the cranks pedal arms will not.

On a fixie if you stop pedalling the cranks will continue to spin. This means that you are essentially always pedalling on a fixed gear bike with no way to coast. On a fixie you can actually brake by preventing the pedals from moving.

This locks the rear wheel in the same way the brakes on a normal bike do. Single speed bikes will have brakes in the same way you would find on any normal geared bike. Fixies are mixed. Some do not have brakes fitted at all relying on road position, rider skill and stopping the cranks to brake.
