How this e-bike scores for different riding styles
Perfect for casual rides with its stable three-wheel design, comfortable step-through frame, and 30+ mile range. The cargo baskets are ideal for picnics and leisurely shopping trips.
Large detachable front and rear cargo baskets plus 260 lb weight capacity make this excellent for grocery runs and hauling. The stable tricycle design provides confidence when loaded, though the 350W motor may struggle with heavy cargo on hills.
The foldable design allows storage in an SUV and is ideal for limited spaces. However, at 74 lbs, it's heavier than most folding e-bikes, making it less portable than two-wheeled alternatives.
The 40-mile pedal-assist range and integrated lights make it suitable for commuting, though the 15.5 mph top speed is slower than typical commuter e-bikes. The large cargo baskets are excellent for carrying work items or groceries.
With no suspension, 20-inch wheels, and a three-wheel tricycle design optimized for stability rather than agility, this is not built for off-road or trail riding.
With only 15.5 mph top speed and 350W motor power, this tricycle prioritizes stability and practicality over performance. Not suitable for speed enthusiasts or those seeking thrilling rides.
Our Verdict
The Soumye S186 is a folding electric trike built around stability and cargo capacity rather than performance. Its 350W motor and 374Wh removable battery deliver 30-40 miles of range at a 15.5 mph top speed—well below the 20-25 mph average for two-wheel electric bikes, but appropriate for the flat errands this e-bike targets.
Three wheels eliminate the balance challenge of a conventional electric bicycle, making the Soumye S186 a practical choice for older adults, riders with mobility limitations, or anyone who wants to stop without putting a foot down. The step-through frame fits riders from 4'9" to 5'8", and the 260 lb weight limit accommodates most adults with room for cargo. Front and rear baskets replace a car for grocery runs and short hauls. The LCD display and integrated lights round out the everyday usability package.
At $509, the Soumye S186 e-bike sits at the entry level of the electric trike category. The 350W motor produces limited torque on inclines—steep hills with cargo will slow you significantly and demand full pedal assist. No suspension means every road crack and pothole transfers directly to the rider. At 74 lbs, loading it into an SUV is a two-person task. If three-wheel stability and cargo-friendly riding on flat terrain are your priorities, the Soumye S186 electric trike delivers solid value at its price point. If you need speed, hill-climbing torque, or a lightweight folder, a standard e-bike will serve you better.
What We Like
- 374Wh removable battery delivers 30-40 miles of range per charge, covering most weekly errand routines without a mid-day recharge
- Three-wheel geometry gives the Soumye S186 e-bike inherently better low-speed stability than any two-wheel electric bicycle at this price point
- Step-through frame accommodates riders from 4'9" to 5'8" tall, making the Soumye S186 accessible to older adults and riders with limited hip or knee mobility
- Front and rear cargo baskets add practical hauling capacity that most $509 electric bikes lack, eliminating car trips for grocery and errand runs
- Folds compact enough to load into an SUV cargo area, giving this electric trike more transport flexibility than most fixed-frame three-wheelers
What Could Be Better
- 350W motor tops out at 15.5 mph, roughly 5-10 mph slower than the category average for two-wheel electric bikes priced similarly at $500-$600
- 350W motor generates limited torque for hill climbing—steep grades with a loaded basket will noticeably reduce speed or require sustained pedaling to maintain momentum
- At 74 lbs, lifting the Soumye S186 into a vehicle is a two-person job despite the folding design, limiting solo portability
- No suspension system means bumps, potholes, and cracked pavement transfer directly to the rider at any speed above walking pace
- No UL 2849 or UL 2271 safety certification listed, unlike many competing electric bicycles in the $500-$700 range that carry independent safety validation
