Hydraulic disc brakes are a popular choice for electric bikes; however, it can be difficult to decide if you should use them or not. While it may seem like a simple feature, the types of brakes you use should be one of your considerations if you are wondering if you should buy an electric bike. Another consideration you need to make is whether you are going to be riding your ebike at night or in bad weather. If so, your electric bike needs lights. Like having lights on your ebike, your brakes will help keep you safe while on your ride. So, follow these tips below to decide if hydraulic braking is right for you.

Key Takeaways:

  • Electric bikes use either mechanical or hydraulic disc braking.
  • Each braking system has pros and cons depending on what you’re looking for.
  • Hydraulic disc brakes offer higher performance and control but are more expensive.

Should You Use Hydraulic Disc Brakes on an Electric Bike?

In order to make the best decision on whether or not you should use hydraulic braking on your favorite electric bike, it’s important to understand your options and the pros and cons of each.

Types of Electric Bike Brakes

The two primary braking systems used for electric bicycles are mechanical and hydraulic. Mechanical disc brakes use a cable system to facilitate braking. The hydraulic disc system uses compression to apply pressure to the brake disc. There are advantages and disadvantages to each system depending on your usage, needs, and other factors.

Mechanical Disc Brakes for Electric Bikes

Mechanical brakes are the legacy braking system that pulls a brake cable tighter in order to apply the brakes to the braking disc.

Advantages of Mechanical Disc

Mechanical disc brakes are the most affordable type of disc brakes. They are generally low-maintenance and, because of their affordability, easier to replace if needed. Mechanical disc brakes also tend to add less weight to a bike.

Insider Tip

  • Mechanical disc brakes are the most affordable type of disc brakes
  • If you’re looking for high-performance braking and great control, then you should look at a hydraulic system for your electric bike

Disadvantages of Mechanical Disc

Because mechanical brakes use a cable to brake, it requires riders to squeeze harder to stop. Additionally, the brake cable will stretch over time and need to be replaced. The brake controls of a mechanical system are less sensitive than hydraulics.

Hydraulic Disc Brakes for Electric Bikes

Hydraulic disc braking is a newer braking system that compresses the fluid in order to brake. There is no mechanical element involved, and no mechanical cables are needed.

Advantages of Hydraulic Disc

Hydraulic disc brakes offer more braking power than mechanical brakes, which is especially important for electric bikes. The hydraulic system also performs better in bad weather. Additionally, hydraulic brakes offer more sensitive braking, allowing riders more control of the bike when operating.

Disadvantages of Hydraulic Disc

Because of the components of the hydraulic disc system and its higher performance, it is also more expensive than mechanical brakes. While hydraulic brakes last longer and require little maintenance, they can be more complicated to maintain and fix on your own if needed.

Which Disc Brakes Should You Use?

To decide if you should use hydraulic brakes on your eBike, consider factors like usage, type of bike, and your budget. If you’re looking for high-performance braking and great control, then you should look at a hydraulic system for your electric bike. If you have a more lightweight electric bicycle and want to keep costs down, then you may want to consider mechanical disc braking.

Tips For Hydraulic Disc Brakes For Electric Bikes FAQ

What are the different types of bicycle brakes?

There are three main brake types for bicycles: disc brakes, rim brakes, and drum brakes. Electric bikes primarily use disc brakes, though some do have rim brakes. Disc brakes can either be hydraulic or mechanical.

What are the advantages of disc brakes?

Disc brakes offer a wider braking range than other types of brakes. This means that the rider can apply subtle amounts of gradual pressure to the brake lever in order to control their speed. Disc brakes are also known to perform better in inclement weather.

Do eBikes need disc brakes?

It is highly recommended to use disc brakes on an eBike. Disc brakes have better stopping power than other brake types, which is necessary when operating an electric-powered motor bicycle.

Mechanical or hydraulic disc brakes?

The pros and cons of mechanical brakes and hydraulic disc brakes is a frequent debate among bikers. While mechanical brakes are generally lighter and cost less, hydraulics have better braking capacity and therefore offer improved control. Hydraulic brakes are ideal for electric bikes.

What components do the best electric bikes have?

The best electric bikes have a hydraulic braking system. Because electric bicycles weigh more than non-electric bikes, it is important that the braking system has a more forceful stopping power to handle the added weight.
