Soumye S186 Folding E-Trike Review: Perfect for Errands & Leisure Rides

The Soumye S186 Electric Tricycle is one of those rare finds in the e-trike market that blends stability, ease of use, and practical design into a single package. Designed with both beginners and seasoned riders in mind, this folding 3-wheel electric trike offers comfort, utility, and a safe riding experience—making it an attractive choice for adults seeking a reliable mobility solution.

From the moment you see the Soumye S186, it’s clear that it’s built for convenience. Its low step-through frame and folding mechanism make it accessible for riders of varying mobility levels, while the integrated cargo baskets at the front and rear make it perfect for grocery runs, picnics, and light cargo transport. Powered by a dependable 350W brushless motor, it offers enough torque for daily commuting without sacrificing maneuverability.

Soumye, the company behind this trike, is known for producing a range of affordable and user-friendly electric bicycles and tricycles. Based in Los Angeles, they combine practical designs with dependable customer service, offering bilingual support (English & Spanish) that makes ownership stress-free.

Is the Soumye S186 for You?

If you’re looking for a stable and comfortable ride without the balance challenges of a traditional two-wheeled e-bike, the Soumye S186 might be your ideal match. It’s especially suitable for:

• Commuters who want an eco-friendly and cost-effective alternative to short car trips.
• Shoppers and errand-runners needing storage space for groceries or cargo.
• Leisure riders who enjoy relaxed park rides or neighborhood cruising.
• Older adults or those with mobility concerns who need a stable, easy-to-mount ride.

This is a mid-range electric tricycle, offering solid value without the high-end price tag of premium e-trikes. It’s beginner-friendly, thanks to its intuitive controls, three riding modes, and comfortable ergonomics. However, if you’re looking for high speeds or advanced off-road capability, this isn’t the trike for you—its design prioritizes stability and comfort over thrill-seeking performance.

What We Like About the Soumye S186

One of the standout features of the Soumye S186 is its 350W brushless motor with a peak output of 540W. It strikes a perfect balance between efficiency and enough power to handle inclines and everyday riding without draining the battery too quickly. Speaking of which, the 374Wh removable battery is a highlight—certified for safety and built with protections against overheating, overcharging, and over-voltage. In real-world terms, that means up to 40 miles in PAS mode or around 30 miles using only throttle.

The folding frame is another major plus. At 74 lbs, the S186 is lighter than many e-trikes in its category, making it easier to store in an SUV or small garage. The adjustable seat height accommodates a range of riders from 4’9″ to 5’8″, and the frame supports up to 260 lbs—enough for most riders and their cargo.

Cargo capacity is impressive, with large detachable baskets at the front and rear. Whether you’re picking up groceries or packing a picnic, this trike is ready for the job. The inclusion of a differential system—something often missing on budget trikes—means smoother, safer turns, especially when carrying heavier loads.

Safety features are well thought out, too. Front and rear disc brakes provide reliable stopping power, even in wet conditions. Integrated front headlight and rear taillight improve visibility during early morning or evening rides, and the LCD display makes it easy to track speed, battery level, and assist mode at a glance.

What We Don’t Like About the Soumye S186

While the Soumye S186 does many things right, there are a few areas where it could improve. First, the top speed of 15.5 mph is adequate for casual riders but may feel limiting for those who want to keep pace with faster e-bikes. For most urban and recreational use, it’s fine, but on longer stretches, it can feel slow.

The single-speed drivetrain is another compromise. While it simplifies maintenance, it limits the rider’s ability to adjust gearing for varied terrain. On steeper hills, you may find yourself relying heavily on pedal assist or throttle.

Additionally, while the folding frame is a huge convenience, at 74 lbs, it’s still not light enough for frequent lifting without some effort. The size, even when folded, might still be a bit cumbersome for apartment dwellers without adequate storage space.
