Among the latest entries into this burgeoning market is the EUYbike S4, a model that promises to combine style, functionality, and performance into one seamless package.

Design & Aesthetics
Right out of the gate, the EUYbike S4 demands attention. Its sleek and modern design is a nod to contemporary aesthetics, ensuring it doesn’t look out of place in urban environments. The frame exhibits a fine balance of rigidity and flexibility, designed with both the casual commuter and the avid cyclist in mind. It proudly showcases the moto/moped design, highlighted by a dual crown suspension fork and a big headlight.
The light ensure visibility during night-time rides, while the responsive braking system offers quick stops when needed. The bike’s construction materials and craftsmanship also suggest durability, so this isn’t a bike that will wear out after a few months of rigorous use. This is an e-bike that you’d be proud to ride around town. The only missing feature here is the turn signals, so I still need to watch out carefully and use hand signals when making a turn.
When it comes to performance, the EUYbike S4 doesn’t disappoint. I’m impressed with the bike’s 1,000W motor and its capability to tackle a range of terrains. The bike boasts a top speed of 28 mph which is way faster than the 20 mph on my previous e-bikes. The cadence sensor ensures that the motor’s power delivery comes as soon as you start turning the pedals. This is not really a smooth transition and many people don’t like the sudden electric boost. It doesn’t provide the natural cycling experience but I got used to it in no time. I often use the twist throttle to start the bike and only start pedaling when it reaches my desired speed.
In the pedal-assisted mode, the pedals become super lightweight and sometimes I even thought the chain dropped off. I can effortlessly ride it for 10-20 miles without a sweat. I prefer using the throttle only because it is much easier to control the speed. When I need to exercise or share road with pedestrians, I often turn off the electric assistance and ride with pedals only. Surprisingly, pedaling this bike feels light and remains comfortable even without the power boost. This ease of pedaling is not common in many e-bikes out there. It’s especially beneficial when the battery depletes, allowing you to continue riding for miles without any issues.
Battery & Range
One of the most critical considerations for any e-bike enthusiast is the range. Fortunately, the EUYbike S4’s battery packs a punch in terms of endurance. The bike’s range of more than 40 miles in throttle mode is more than sufficient for daily commuting and even some extended recreational rides. Furthermore, the easy-to-access battery allows users to quickly remove and recharge it at any place, reducing the range anxiety that can sometimes come with electric vehicles.
Ride Comfort & User Experience
It’s evident that the designers of the EUYbike S4 prioritized rider comfort. The thick padded seat, ergonomic grips, and overall geometry of the bike cater to a range of body types and riding preferences. It is not adjustable but I feel very comfortable riding the bike for hours. The fat tires, full suspension and mid-mounted shock absorber do a commendable job of absorbing shocks from uneven terrains, ensuring a smooth ride even on bumpy city streets. I tested some fat-tire e-bikes with front suspension fork but they didn’t deliver the same comfortable and smooth rides.
The user interface is intuitive, with a clear display showing essential metrics like speed, battery level, and distance traveled. The inclusion of multiple assist levels allows riders to customize their experience based on their needs and the terrain.
