We recently had the opportunity to compare two popular electric bikes: the Aventon Sinch and the KBO Flip. Both bikes offer a foldable design and are great options for those who need a compact and portable mode of transportation. However, there are some notable differences between the two that we will explore in this article.

One of the main differences between the Aventon Sinch and the KBO Flip is their respective motor power. The Aventon Sinch features a 500W (750W peak) motor, while the KBO Flip comes with a 500W motor. This means that the Aventon Sinch has more power and is able to tackle steeper hills with ease. However, the KBO Flip is still a capable bike and may be a better option for those who don't need as much power.

Another difference between the two bikes is their battery capacity. The Aventon Sinch has a larger battery capacity, which may allow for a longer range than the KBO Flip. Overall, both bikes have their strengths and weaknesses, and the best option for you will depend on your specific needs and preferences.

Both bikes have their strengths and weaknesses in terms of suspension, brakes, wheels, and tires.

Starting with the Aventon Sinch, this eBike comes with an spring suspension fork that provides a 80mm of travel, making it suitable for light off-road use. The suspension does a good job of absorbing small bumps and vibrations on the road, but it can feel a bit stiff on larger bumps. The front suspension is paired with 180mm mechanical disc brakes that offer reliable stopping power in all conditions.

The Aventon Sinch also comes with 4-inch wide tires that provide good traction on loose terrain and a comfortable ride on pavement. The tan wall tires add a classic touch to the bike's overall appearance.

On the other hand, the KBO Flip features front suspension only, which is also a spring suspension fork. The suspension fork does a decent job of absorbing small bumps, but it can feel a bit jarring on larger bumps. The KBO Flip also comes with mechanical disc brakes, but they are not as powerful as the brakes on the Aventon Sinch.

The KBO Flip has 20-inch by 3-inch fat tires that provide good traction on loose terrain and a comfortable ride on pavement. The tires are not as wide as those on the Aventon Sinch, but they do make the bike feel more stable on rough terrain.

Logo

Overall, both bikes have decent suspension and tire setups, but the Aventon Sinch has the edge in terms of braking power. The wider tires on the Aventon Sinch also make it a better choice for riders who plan to do more off-road riding.

Pedal Assist & Throttles

Aventon Sinch: Pedal Assist & Throttles

KBO Flip Half Twist Throttle

KBO Flip: Half Twist Throttle

There are two main ways to control the power assistance on an electric bike: pedal assist and throttle.

Pedal assist, also known as PAS, is a system that provides power assistance when you pedal. The system detects the movement of the pedals and activates the motor to provide additional power. Most eBikes come with five levels of pedal assist, which allow you to adjust the amount of power assistance you receive. The higher the level, the more power assistance you receive.

On the other hand, the throttle system allows you to control the power assistance with a thumb or twist throttle. This system is similar to the one used in motorcycles, where you twist the throttle to increase the power. With a thumb throttle, you can control the power assistance without pedaling.

Both systems have their advantages and disadvantages. Pedal assist is more natural and provides a more comfortable riding experience. It also helps you to exercise more, as you need to pedal to receive power assistance. However, it can be less intuitive and may require some getting used to.

Throttle, on the other hand, is more straightforward and easier to use. It provides instant power assistance, which can be useful in some situations, such as when starting from a stop. However, it can be less efficient and may drain the battery faster.

In our experience, both systems have their place, and it depends on your preference and riding style. If you prefer a more natural and intuitive riding experience, pedal assist may be the way to go. If you want a more straightforward and effortless ride, throttle may be the better option.

Overall, the Aventon Sinch and the KBO Flip come with both systems. It's important to understand the different power assist options and choose the one that fits your needs and preferences.

Portability

When it comes to choosing a folding electric bike, portability is a key factor to consider. In this section, we will compare the portability of the Aventon Sinch eBike and the KBO Flip.

The Aventon Sinch eBike features a folding frame that allows it to be easily stored in small spaces. The bike can be folded in seconds and can fit in the trunk of a car or in a small closet. The bike weighs 68 pounds and features a stem that can be collapsed, making it even more compact.

The KBO Flip, on the other hand, also features a folding mechanism very similar to the Aventon Sinch’s. The bike can be folded in half, reducing its total length by 50%. The bike also features a lightweight frame, weighing only 57 pounds. The bike can be easily carried up stairs or onto public transportation.
