Do carbon bikes break easily?
Carbon fiber is strong, but not durable, so if you’re riding on a “crappy” road then you don’t have to worry about it breaking, but you might damage it if you hit a rock or something.
The reason for this is that carbon fiber is a “composite material” – it’s made out of long “fibers” of pure carbon that are suspended in a “matrix” material, usually some sort of epoxy resin. The fibers have a layered structure to them that makes them much stronger along their length.
So although carbon fiber is designed to be strong if you use it as intended, if you somehow hit it perpendicular to the fibers then it’s actually pretty weak.And since it’s embedded in plastic, the material isn’t very tough, and can get scratched really easily.For a direct comparison, reinforced concrete can often be “as strong as steel” but if you hit it with a hammer it will definitely chip a lot easier than steel.
Now, carbon fiber is so incredibly strong that you can make it resistant to damage by just overbuilding it, and you’ll still wind up with a lighter-weight bike than if you made it out of metal.
But unless you’ve gotten a carbon bike that’s specifically designed to be durable, they’re a lot more fragile than usual. They’re actually less likely to break on you than a metal bike is, but you have to be way more careful not to damage them.
What is the best folding bike brand?
A few years ago, folding bikes were so unpopular and consumers have just a limited number of choices. At the moment, we can see them everywhere in the United States, from online retailers like Amazon to brick-and-mortar stores like Target, Walmart or Sports Authority.
While this is good news for us, it also means you might have to spend a lot of time researching and deciding which is the best folding bicycle for your needs. We love folding bicycles and it is better test them so we know this is not an easy decision, especially for inexperienced shoppers.
Many people have the prejudice against this type of bicycle because they think it is more expensive, bulkier and can’t compete with regular full-sized bikes. The viewpoint is no longer valid as there’ve been a lot of improvements in design and materials of folding bikes in the last decade. The disadvantage of being unwieldy is solved as folding bikes are so compact and lightweight that you can put two of them in your car trunk. The weight of most recent folders is made lower than 30 lbs and we even see some lighter than 20 lbs.
Folding bicycles are suitable for anyone who wants to use a bicycle at more places, for people who are aware of their health and looking for the most healthy and environmentally-friendly way to get around. Urban commuters would benefit the most from folding bikes because they don’t have enough space to store a conventional bike and need to solve the last-mile problem.
There is no the best folding bike, but it is important to find the one that suits you.
carbon fiber bike frame lifespan
Carbon fiber bike frame doesn’t fatigue like aluminum, however uncoated carbon fibre and the impregnated resin can be weakened / damaged over time by exposure to Ultraviolet light (UV). For this reason many carbon fibre frames are painted with either an opaque paint or something with UV protection (inhibitors or absorbers). Provided you don’t subject the bike to fire, chemical attack or a hit big enough to break it, or put a notch in the frame or fork, thereby causing a stress concentrator, it should last a very long time. With proper care it may outlast the rider.
If you look after the bike, keep it out of the sun when you’re not riding it and don’t subject it to big hits, like crashing, thus staying under the failure limit of the material, it should last a very long time.
Unless they are damaged or poorly built, carbon bike frames can last indefinitely. Most manufacturers still recommend that you replace the frame after 6-7 years, however, carbon frames are so strong that they often outlast their riders.
carbon fiber bike frame weight
The average carbon folding bike weighs approximately 8.2kg (18 pounds). Like every other bike category, the frame size, frame material, wheels, gears, and tire size can change the overall weight. Carbon fiber bike frames are strong, reasonably stiff and in fact, the lightest.Usually the weight of carbon frame is around 800g.
Heavier cyclists should be mindful of weight limits for security reasons and to ensure the durability and functionality of the products they buy. Frame and wheelset manufacturers establish weight limits based on performance metrics for rider safety, to protect themselves legally, and to have a solid guarantee behind their products.
For many riders, the weight of the bike is the primary concern. Having a lightweight bike makes climbing easier and can make the bike easier to manoeuvre. Whilst it’s possible to make a light bike out of either material, when it comes to weight, carbon definitely has the advantage. A carbon fibre frame will almost always be lighter than an aluminium equivalent and you’ll only find carbon fibre bikes in the pro peloton,in part because of the weight benefits.
