Best foldable electric bicycle: Aventon's Sinch or SDream X Foldable Ebike?

Updated: Dec 14, 2021

If you want a foldable electric bicycle for commuting and leisure time, you may have come across Aventon and SDREAM during your research. Both companies make great foldable electric bikes, but which one do you buy?

In this post, we will compare the SDREAM UR 500X and the Aventon Sinch to help you decide which is best for you.

About Aventon Bikes

Aventon Bikes prides itself on producing accessible and well-made electric bikes. They have a network of dealers across the U.S and Canada, but you can also buy the bikes directly from their website.

They have a wide range of electric bikes to suit the different needs of their customers.

About SDREAM Bikes

SDREAM Bike is based in the U.S. and has a very different style to Aventon Bikes, but they are of fantastic quality and look great. They have two electric bicycle’s in their lineup, both with folding frames.

The company is based in Los Angeles, California, but SDREAM has certified distributors in both the U.S. and Asia.

Aventon's Sinch Series Vs. SDREAM X 750S Foldable Bike Comparison

Aventon's Sinch and SDREAM's X 750S are direct competitors, as they offer very similar features.

The first thing you notice about each foldable electric bicycle is their fat tires. They both come with 20" X 4" tires, which give you specific advantages over regular-sized tires.

Their extra width creates a large contact patch with the ground, giving you lots of traction on various surface types. Therefore, these electric bikes are great for light off-road use.

The other advantage of fat tires comes from their high volume. The extra squish they have makes riding over rough ground more comfortable.

Aventon and SDREAM chose 20" diameter wheels for these bikes for a couple of reasons. This smaller size makes the bikes more compact when folded, allowing you to store them in tighter spaces.

The other advantage of 20" wheels is that they give the bikes' agile handling. This is really handy when you need to avoid obstacles and people when riding in town. But it also makes the bikes great fun to ride both on and off-road.

To make the ride even more plush, both bikes have suspension. The difference is that the Aventon Sinch has a suspension fork, while the X750 S has the suspension on the centre hub. Both systems work well, but the SDREAM suspension just pips the Sinch in the comfort stakes.

Bike Battery

Both bikes come with a 750W rear hub motor, which gives you lots of power for most types of riding, whether you are riding the streets or off-road.

Both electric bikes have integrated batteries which help with the bike's aesthetic while protecting the batteries from the elements. You can remove the batteries to charge them or replace them with spares to extend your range.

Powering the SDREAM's motor is a 48V / 10.4Ah 500Wh lithium-ion battery with Samsung cells. This high-quality item gives you Up to 50 miles (80 km), depending on how you ride and the profile of your route.

The Sinch is powered by a Lithium-ion 48V, 14Ah (672 Wh). This may seem like a better battery, but the cells are not as high quality, so it only gives you 40 miles of range.

Brake System

Aventon and SDREAM have fitted their bikes with powerful disc brakes. However, the Aventon Sinch is trumped by the SDREAM X750 S's hydraulic disc brake setup with 180mm rotors.

The hydraulic system is more powerful than the Sinch's mechanical brakes. You also get more control from hydraulic brake levers, thanks to superior feel and responsiveness.

Therefore, if safety and control are high on your list of preferences, the SDREAM bike would be a better choice.

Foldable Ebike Prices

The Aventon Sinch comes in at $1,699, while the SDREAM X750 S is priced at $1,199.00. Although the Sinch is a good bike, the SDREAM X750 S is comparable in quality and style for much less money.


These bikes are both limited to a top speed of 20mph. This may not sound like much, but they are fast enough to overtake inner-city traffic and have plenty of fun on. T

Frame Sizes & Design

From the online photos of these bikes, you may think that they are similar sizes to a BMX bike. However, you may be surprised to learn that they are much bigger in real life.

But due to their frame design, they are effortless to mount and dismount. If you make your decision based on how each bike looks, it is down to personal preference. However, it is widely agreed that SDREAM's frame design is more elegant and stylish.

Both bikes fold up to a compact size, which may sway your decision depending on your storage space.

The folded dimensions of the Sinch are 41" L / 23" W / 31" H, while the SDREAM comes in at 27.6 L / 15" W / 30.3" H. So if space is tight, or you want to carry your bike in the car or on public transport, the SDREAM may suit you best.

Ebike Controller

Aventon uses a basic backlit display. It gives you information such as your speed, pedal assist level, how far you have ridden, and how much range you have. Even though it is pretty simple, the LCD is easy to read, which is good when riding in traffic.

SDREAM's controller is more advanced than the Aventon item. The information is brightly lit, with excellent contrast with the background.

SDREAM has given the controller a good IP rating to keep it safe from water and dirt. The information displayed includes ride metrics, battery information and allows you to scroll through advanced settings.

You can also charge your phone from it, using the integrated USB charging port as an extra bonus.

Final Thought

Both bikes are fun to ride and convenient. But, the SDREAM X750 S is better looking, smaller when folded, and has a more extended range.

These advantages, combined with its lower cost, make the SDREAM X750 the best choice.
