What's the difference between hydraulic and mechanical disc brakes?
The major difference between hydraulic and mechanical disc brakes is that the latter uses a cable similar to a derailleur cable, while the former uses brake fluid similar to what’s used in cars.
As previously mentioned, mechanical brakes make use of a cable in order to brake. Just like a derailleur cable, dirt can affect their performance and stretch them out. Mechanical brakes do not stop as efficiently as hydraulic brakes, however the simple cable makes them easier to adjust. Mechanical brakes offer easy adjustments if you like adjusting your brakes on the fly, and are more common as well as cheaper to replace.
Hydraulic brakes are designed to use brake fluid, which becomes compressed when the brake lever is squeezed and allows the brakes to function. This is a superb technique that offers stronger, more reliable braking performance. However, the technique will cost you more than the brakes themselves. You will have to ensure that the brake lines are air free, and maintain care for the brake fluid in case their performance starts to suffer.
Just like with brakes of your car, you will have to change the fluid at times. (Luckily this only needs to be done every so often.) Keep in mind that these brakes are in an enclosed system, meaning you don’t need to worry about mud and dirt affecting the performance of your bike. The only exception for both hydraulic and mechanical brakes is if the pads themselves get dirty.
Hydraulic Brakes Pros and Cons:
- Excellent modulation
- Unsurpassed stopping power
- Open Systems with huge rotors capable of handling very high loads of heat from “heavy-duty” riders
- More expensive
- Closed systems can blow off or lock-up or blow-off hydraulic seals/lines if overheated

What is the difference between a 2A and a 5A charger?
There are two types of Pedal Assist: Cadence Sensor Type which measures IF you are pedaling and a Torque Sensor Type which measures HOW HARD you are pedaling. The Super73 S-Series sold in the United States with thumb throttles, as well as the Super73-SG (Global) has a cadence sensor. The Super73-SG1, sold outside North America, and doesn't come with a throttle, has a torque sensor.
1. Cadence Sensors
The advantage is that it's an inexpensive way to get some sort of pedal assist onto the bike, but the disadvantage is that the pedal assistance can feel jerky, laggy and counterintuitive. If you want to pedal faster than the motor is spinning, the motor will actively work against your efforts. The Super 73 has a cadence sensor as it is most often used with the throttle only.
2. Torque Sensors
The harder you pedal, the more power it gives to the motor. If you pedal lighter, less power goes to the motor. It makes this adjustment in real time so it is technically amplifying your every input. It feels like you're bionic.
Most all higher-end e-bikes use torque sensors and in some countries, cadence-only sensors are not allowed to be sold. The disadvantage is the cost is significantly higher to implement this technology as the precision component is relatively more expensive.
