Depends.
If possible, it takes quite a bit of doing. External gear hubs are usually wider than internal gear hubs, so you'll probably need to respace the frame.
No big deal if it's a steel frame, not advisable for aluminium frames. Not possible for carbon fiber frames.
Buying a new rear wheel is probably least expensive, but it'd be possible to rebuild your old wheel with a new hub.
Then you'd need a shifter, a derailer, possibly an adapter claw to mount the derailer, and some cabling.
You need to figure out how to run & secure the cabling as your bike won't have the required brackets.
Or you'll have to track down several wraparound cable stops.
Realistically, you can expect to spend more on the conversion than what a new used bike with the desired properties would have cost you.
Converting a freewheel to a cassette on your bike involves replacing the entire rear wheel hub. This requires removing the old freewheel and installing a new cassette-compatible hub. It is recommended to seek assistance from a professional bike mechanic to ensure the conversion is done correctly.
There are mainly two types of bike cassettes available in the market: freewheel and cassette. Freewheel cassettes have the gears attached to the hub, while cassette cassettes have the gears separate from the hub. Each type has its own advantages and disadvantages, so it's important to choose the one that best suits your biking needs.
Converting a freewheel to a cassette on your bike involves replacing the entire rear wheel hub. This process requires specific tools and mechanical knowledge. It is recommended to consult a professional bike mechanic for assistance with this conversion.
Your bike cassette may wobble due to loose or worn out components, such as the lockring or cassette itself. This can cause the cassette to not sit properly on the hub, leading to the wobbling.
To use a cassette wrench on a bike for maintenance and repair, first, remove the rear wheel from the bike. Then, use the cassette wrench to loosen the lockring on the cassette. Once the lockring is loose, carefully remove the cassette from the wheel hub. To reinstall or replace the cassette, reverse the process by tightening the lockring with the cassette wrench. Make sure to securely fasten the cassette to the hub before reattaching the wheel to the bike.
To remove a cassette from a bike, you will need a cassette removal tool. First, remove the wheel from the bike. Then, insert the removal tool into the center of the cassette and use a wrench to turn it counterclockwise to loosen and remove the cassette from the hub.
To remove a bike cassette, you can use a specific tool called a cassette lockring remover. This tool fits onto the lockring of the cassette and allows you to unscrew it, enabling you to remove the cassette from the wheel hub.
An internal hub bike offers advantages such as low maintenance, protection from elements, and ease of use compared to a traditional bike with external gears.
To convert a single-speed bike to a three-speed bike, you will need to replace the rear wheel with a wheel that has a built-in internal gear hub. This hub will allow you to shift between three different gears, giving you more versatility in your riding. Additionally, you may need to install a new shifter and cable to control the gears. It is recommended to consult a professional bike mechanic for assistance with this conversion.
A cassette hub has the freewheel mechanism built into the hub itself, allowing for smoother and more efficient pedaling. A freewheel, on the other hand, is a single unit that threads onto the hub and contains both the sprockets and freewheel mechanism. If you are looking for better performance and durability, a cassette hub would be more suitable for your bike.
To remove a freewheel cassette from a bike, you will need a special tool called a freewheel remover. First, remove the wheel from the bike. Then, insert the freewheel remover into the center of the cassette and use a wrench to turn it counterclockwise to loosen and remove the cassette from the hub.
