SINAR S7 Review: Powerful Off-Road Folding E-Bike!


The SINAR S7 is a portable, powerful, and tiny device. The model with a 750 Watts drive is also growing in popularity in this country, despite the fact that it is illegal to drive it on public roads in the EU. In this test, you may find out what the low-cost SINAR is capable of.

Fat 20 x 4-inch tires, a strong 750 W rear-wheel drive, and a battery with a 15 Ah capacity are all included. All of this costs $1299, which is considerably less than the majority of the e-folding bikes permitted in this nation. The SINAR S7, which was mentioned at the outset, is likely the biggest catch here.

Because it is illegal to move an e-bike on European roads with the throttle grip fitted. More information on this subject is available in our guide to the numerous laws and regulations.


The SINAR S7 left a nice impression overall because of its attractive packaging. I would definitely mention the slightly bad rear brake cable on my model if I were to voice a complaint. Because something from the frame’s rear structure, which is spring-loaded, is to blame. 

In addition, mounting the rear fender was a little challenging, but that is unrelated to the bike itself. A little tip: You can really get good results by letting the tire’s air out without taking the back wheel off. Overall, the bike looks sturdy and is expertly constructed.

SINAR S7: Design and Build Quality

It’s uncommon to find a folding bike with full suspension. Suspension in the front and back is more of an exception than the rule, even if we previously had the Jeep folding bike and the Engwe e-folding bike in our test, which is more like a tractor. Even so, the SINAR S7’s suspension has been fine-tuned. The tiny bike offers a lot of comfort in combination with the big tires.

The S7’s folded dimensions are 970 x 780 x 440 mm. Thus, it is not a Brompton. To be fair to SINAR, it’s not attempting to be a Brompton, and the fact that it folds makes it much simpler to transport it in a car or on a train. Additionally, the handlebars and pedals fold, and the crank has a built-in stand that maintains the bike upright when folded. Although it’s unfortunate that there isn’t a clip to hold the wheels together like on the Gocyle GX, bungee cords aren’t particularly expensive.

Doesn’t even somewhat interest SINAR. You can easily navigate uneven terrain, including muddy forest trails and gravel highways. However, in the test, the e-folding bike was equally comfortable in the city. It doesn’t feel entirely huge, despite the slightly louder rolling noise caused by the large tires. In any event, minor trip risks like train rails are no longer a concern.

At this time, it is also necessary to mention the front suspension fork. It is among the best affordable e-bikes I’ve recently tested. It is really stable, presents a highly premium image, and can even be slightly changed.

Regarding the actual folding mechanics of the bike, there isn’t much to mention. The handlebars and main frame can be folded, the hinges are strong, and the hinge locks are reliable. The SINAR S7 can fit in any trunk when folded up and is incredibly small. Additionally, the pedals can be folded.

The battery can be taken out of the frame when it is opened. So you may charge the battery inside your own four walls in addition to immediately on the bike.

SINAR S7: Motor and Driving

You have a variety of speeds for both on- and off-road riding thanks to the rear hub’s 750W brushless XiongDa motor, and 8-speed Shimano cassette.

The system’s use of a cadence sensor rather than a torque sensor is one obvious flaw, though SINAR doesn’t provide much details about the rest of the setup. This results in a considerably jerkier and unnatural power delivery.

The S7’s legal speed limit in the EU is 15.5 mph (25 km/h), however when it is unrestricted for off-road use, it can reach 24 mph (40 km/h). We were unable to locate any instructions for doing this in the user manual or on SINAR’s website. SINAR did, however, describe the process once we asked.

The 750 W of the drive, in my opinion, has sufficient power and is obviously evident in terms of driving behavior. When you press the throttle grip, you can really tell that something is happening. Although it’s prohibited, it’s actually a lot of fun. But truly, you can only ride the bike on your own land. 

But in this case, the SINAR S7 would make the most of its advantages, because it moves quickly, simply, comfortably, and sportily. Even more so with the throttle already in place. Any ascent, no matter how easy, can be completed.

The S7 is remarkably nimble for its weight and thick tires. The motor has a considerable level of torque, which makes climbing hills easy. I say “you,” but what I really mean is “me,” and my weight is just under the 70 kg that SINAR takes into account when calculating the maximum range.

You’ll experience it as being much slower if you’re closer to 120 kg. The S7 had little issue reaching the summit of my typical long, steep hill while maintaining a respectable speed of 20 km/h, which is the measurement utilized on the bike’s speedo. It might be possible to modify it, but the incredibly brief user manual makes no indication of doing so. 

Two buttons for the horn and light are also located on the side next to the control panel. Unfortunately, the StVZO states that the latter is likewise prohibited in Germany. Additionally neatly positioned on the display is a USB port. For anyone who enjoys using their smartphone for navigating, this is a huge benefit.

The fact that the system only functions with the key inserted, however, adds a hint of bitterness to the control. What some people consider as a drawback, others see as a benefit. It may also be slightly safeguarded from thieves because the SINAR S7 won’t operate without the key.

SINAR S7: Conclusions

The SINAR S7 is likely to satisfy anyone looking for a reliable, powerful, small, folding, and nevertheless sporty e-bike. Despite its size, it’s very enjoyable and reasonably priced. Anyone who chooses to purchase the SINAR S7 should be aware that it is illegal to operate it on our roads for a number of reasons. 

Not expecting to enjoy the S7 as much as I did. The motor has enough power to handle the added weight, so it’s not really a problem compared to many other electric bikes.

Additionally, riding off road is a ton of fun not necessary for mountain biking, but for wooded paths and any surface other than tarmac. There are better options if you want a bike primarily for riding on the road.

If you don’t care about that or don’t intend to do it anyhow, the e-folding bike from SINAR is a fun little toy. You can look at the Himo ZB20 Max, which we also evaluated, if you’re seeking a comparable model with the required certification.

The bike may be purchased directly from SINAR, and its bigger brother, the SINAR S7 Pro with 750 W, is also available through a number of online retailers, including Amazon.
