Can you do whatever you want on an electric bike

Can you do whatever you want on an electric bike

So you need to replace the sprockets on your electric bike, but they seem expensive, especially compared to freewheels. Do you need to buy an expensive flywheel, or can you install a flywheel on your e-bike?

You can flywheel on an e-bike, but only if the rear wheel is designed for a flywheel. Generally, taxiing can be done using a flywheel or a flywheel and cassette system. Flywheels are considered inferior and tend to be used in less expensive e-bikes.

In this article, I’ll go into detail about what exactly an e-bike flywheel is and how it’s different from a flywheel. I’ll also consider fixed gears and cassette systems and whether it’s a good idea to swap them out with the flywheel.

What is a flywheel?

The cassette is a sprocket set screwed onto the rear hub. When you pedal forward on an e-bike with a flywheel, you will travel forward. When you stop pedaling, the pedals stop and you will coast. If you pedal backwards with the flywheel, it has no effect.

A flywheel works by allowing the outer body to turn freely in only one direction. An internal ratchet mechanism prevents the flywheel from engaging in the other direction.

This spring-loaded component is called a pawl, and when a cyclist pedals, it engages a pair of teeth that move the wheel forward. When an e-cyclist stops riding an e-bike (same as a conventional bike), the pawl extends so the flywheel stops moving. This allows the rider to coast without the pedals continuing to spin.

As the e-bike coasts, the pawl of the flywheel makes the familiar ticking sound.

Because most e-bikes, as well as standard bikes, have freewheels, they are easier to ride without exhausting yourself. This is why experienced cyclists and those who ride primarily for exercise may not want a flywheel.

What is a Liberty Hub?

A free hub is a rear hub with a cassette ratchet mechanism built into its body. It is only replaced when the hub’s sprocket is worn, not the ratchet mechanism. Unfortunately, cartridges and freehub systems are not interchangeable, as new cartridges can only be used with the corresponding freehub.

Traditional rear hubs have standard threads to which any freewheel can be screwed. As a result, cyclists can put almost any brand of freewheel on their hubs. Then, if the sprocket wears out or the rider wants a different gear ratio, they can remove the cluster and replace it.

Freehubs has several advantages that make it standard.

strength. The shaft bearings on the flywheel system are spaced farther apart, and this extra spacing makes the flywheel system less likely to break.
More gear. The freehub design allows for a larger hub body. Most flywheel systems have 5-7 speeds, while the flywheel can reach 10+ speeds.
Easier to replace. Removing sprockets from an e-bike’s freewheel is a challenge because they tighten the threads of the hub as you pedal. On the other hand, it’s easier to remove the sprocket from Freehub.
Shimano registered the Freehub name when they started selling these hubs with cassettes. Since then, freehub and cassette have often been used interchangeably.

How is a cassette system different from a flywheel?

A flywheel system differs from a flywheel because the ratchet mechanism that allows the rear wheel to spin freely is built into the hub body. Therefore, when the sprocket on the cassette is worn, there is no need to remove the entire ratchet mechanism, just the sprocket.

This can lead to confusion as some people use the term cassette when referring to freehub. Both the flywheel and the flywheel/freewheel have rear hubs.

So to make it clear for yourself – keep in mind that cassette and flywheel refer to the same system for a sprocket or gear that connects to the rear wheel.

Fixed Gear Electric Bike

The term fixed gear for an e-bike can mean one of two things. The first is that the action of the pedals is directly related to the movement of the rear wheels. In other words, if you ride the bike forward, the pedals are also turning.

Since the pedals of the bike turn whenever the rear wheel spins, coasting is difficult. However, you can slow down the rear wheels by applying reverse pressure to the pedals (or pedal backwards).

But the second and more common fixed gear use in e-bikes is fixed speed. Fixed or single speed refers to e-bikes with only one gear.

So the speed of an e-bike depends on how fast you pedal and the power of the e-bike. Plus, since it only has one gear, a single-speed “fixie” is more reliable, lighter, and less expensive than a geared e-bike.

However, fixies are not without their weaknesses. The lack of gear means that if the rear hub motor isn’t particularly powerful or the battery capacity is low, going up hills can be more difficult.

Most fixed gear e-bikes still have a freewheel mechanism. However, the term fixed gear refers to a gear (or no gear), while a flywheel refers to a wheel.

But given that e-bikes are all about “electric,” the terminology associated with shifting is confusing. “Fixed gear” can add confusion.

Can the cassette be replaced with a flywheel on an e-bike?
The flywheel can be swapped with the one on the e-bike, but it doesn’t make much sense to do so. Not only do you need to get new hubs, but you also need to replace the wheels. Also, you won’t save a lot of money unless you make your own laces.

It should be noted that cassette hubs are not as durable as cassette cassettes. Therefore, you will rarely see a freewheel on the highest quality e-bike brands. By switching to a freewheel setting, you are downgrading your e-bike.

What’s more, changing a cassette with a cassette is not as simple as changing one cassette and adding a cassette hub. The laces on the wheels also need to be replaced.

Replacing a wheel isn’t impossible, but it can be complicated, especially on the first try.

To replace the wheels on your e-bike, you will need:

Disconnect the e-bike from battery charging
Remove the wheel (hence the hub motor on most e-bikes)
put on new laces
Adjust the tension
real electric bike wheels
Unless you have extensive experience with e-bikes, you will need to have your bike shop repair and maintenance staff do this.

Unfortunately, upgrading an e-bike flywheel to a flywheel and flywheel system will give you similar problems. Ultimately, though, the system on your e-bike is likely the one you want to stick with.

The Bottom Line on Electric Bike Flywheels

Whether or not you can install a freewheel on an e-bike depends largely on the type of hub system you are currently using.

Flywheels are considered inferior and are often found on lower-priced e-bike models. Still, they’re satisfactory for most e-bikes with rear hub motors. If your e-bike already has a freewheel on the rear wheel, you can replace it with another.

However, upgrading from a cassette and flywheel system to a flywheel is expensive and probably not worth it. The good news is that you can coast on an e-bike with either system.

What are disc brakes?

Disc brakes include discs, pads and pistons. The discs rotate in sync with the wheels on the bike, which is why the brakes get their name. There is a pad on each side of the disc, flush with the disc and piston.

When the rider hits the brakes, the piston presses the pads against the disc. When the pad is pressed against the disc, friction is created, causing the e-bike to slow down or stop, depending on the amount of pressure. Larger disc brakes have more friction, so they stop faster and have less pressure on the brakes than smaller disc brakes.

Disc brakes are common in many moving objects, such as pedal-assisted e-bikes, conventional bicycles, and cars.

However, when you use an e-bike or other vehicle a lot, the brake pads start to wear out over time, especially when you brake hard or often. Make sure to check your brakes and replace them when they start to wear out.

Highly rated hydraulic disc brake kits are great disc brakes for e-bikes and other bikes. They measure 160mm (6.29in) and come with pads so you just attach them to your e-bike and start riding.

Types of Electric Bike Disc Brakes

You can find two types of disc brakes on e-bikes; mechanical and hydraulic.
Mechanical Disc Brake
Mechanical disc brakes use a cable that connects to the brake and a brake button or lever on an e-bike. When you press the button to stop the bike, the brake cable connects with the brake pads and causes it to clamp to the brake rotor, thereby stopping your e-bike. This mechanical disc brake system is similar to how a normal bicycle brakes.

You can adjust the mechanical disc brakes to be closer or further away from the disc, which changes the speed or speed of the e-bike brakes. Your e-bike brakes easier when the pads are closer to the disc, and you don’t have to hit the brake lever as hard to stop it. When they are farther from the brake rotor, you have to press the brake lever harder to stop the bike.

Hydraulic Disc Brakes

The second type of disc brakes, hydraulic brakes, use oil to brake e-bikes. Oil lines in the brake system go from the lever to the disc brakes. When you brake an e-bike, the oil puts pressure on the brake pads. The more you depress the brake lever, the more pressure in the braking system, making you stop faster. This is especially important in wet or icy weather.

You can’t adjust hydraulic disc brakes as easily as mechanical brakes. They automatically adjust the distance between the pad and the disc. So if you’re having trouble braking on an e-bike and have hydraulic disc brakes, you’ll need to have a bike mechanic adjust them.

Choosing Disc Brakes for Your Electric Bike

Disc brakes are the most common on e-bikes, and for good reason. They offer some of the biggest benefits, especially when it comes to reaction time.

Bigger disc brakes are better

Most disc brakes work with e-bikes, but different sizes can affect how the disc brakes work. Ideally, bigger is better, especially on the front wheel where most of the braking is done. The front brake isn’t as useful as the rear brake, but it’s the most important brake when you need to stop quickly, such as in high-traffic areas, where a quick stop is critical.

Larger disc brakes also make it easier for your e-bike to stop. When you have big disc brakes, you don’t have to press the brake lever like you do with smaller disc brakes. Less pressure means it’s easier for you to stop when you need to, which is great for sudden stops and less wear on your braking system.

Materials affect cost and quality

Also, disc brakes come in different materials. Some options include aluminum, plastic and steel. Different materials can change the cost of brakes, how long they last, and how well they work in intense riding and in different weather. For example, steel brakes are best for braking in rain or other wet conditions and sudden stops.

You also need to consider brake pads. Several factors can affect them, such as riding frequency, road and weather conditions, and the quality of disc brake components. So if you are harsh with them, you may need to replace them frequently. This should be considered when purchasing disc brakes.

Fortunately, buying new brake pads is not expensive, and you should always choose the best pads for your situation.
