Design and Build Quality

The PVY S2, with its impressive design and build quality, offers a delightful riding experience, accentuated by its remarkable shock absorbers. The rear shock absorber, in particular, stands out for its softness, providing a pleasant sensation during rides. The front shock absorbers, while not as pronounced as the rear, still contribute to a comfortable and smooth ride.

Weighing a mere 19 kg, the PVY S2 surprises with its lightweight construction, making it easy to lift and maneuver. Despite the inclusion of front shock absorbers, the weight remains surprisingly low. The manageable weight is further complemented by the folding feature of the handlebar and pedals, allowing for convenient transportation and storage. However, it’s worth noting that the frame itself is not foldable.

PVY S2 Review: controls and handlebars

Adjustability is a mixed bag with the PVY S2. While the saddle offers some height adjustment, it falls short in terms of range, providing only a limited 10-15 cm. On the positive side, the handlebar can be folded, enhancing portability. Unfortunately, the handlebar lacks height adjustment, which might be a drawback for riders seeking a more customizable fit.

PVY S2 Review: dual suspension

A notable feature is the support for riders up to 120kg, showcasing the robust build of the bicycle. The inclusion of a small bell on the left side of the handlebar adds a touch of convenience, while the multifunction display on the right side provides a user-friendly interface with a single button for various functions.

An interesting quirk is the method to activate the front and rear lights. The key lies in a two-step process, where the first turn activates the bicycle and multifunction display, and the second turn powers on the lights. It’s a unique approach that users might find perplexing initially. The rear LED light not only serves as an indicator but also functions as a brake light, adding a safety feature to the bike.

One noteworthy consideration is the maximum recommended height of around 180 cm. Taller riders may find that their knees come in contact with the key while riding, which could be a potential discomfort.

Despite minor quirks and adjustment limitations, the PVY S2 impresses with its overall design, build quality, and thoughtful features. From foldable components to efficient lighting and robust shock absorbers, it offers a compelling package for riders looking for a reliable and enjoyable electric bicycle.

PVY S2: Motor and Driving Test

The PVY S2 boasts a 250 W motor, providing riders with a reliable and efficient source of power for their electric biking experience. This motor is well-suited for urban commuting and leisure rides, offering a balanced combination of performance and energy efficiency.

PVY S2 Review: "250W Brushless Motor (Unlocked 350W)"

The PVY S2, upon arrival from the factory, comes with a unique feature that sets it apart—the accelerator is initially blocked at the Walk Assist function. This means that when the bicycle is accelerated, it moves at a maximum speed of 5 km/h, essentially functioning as a Walk Assist mode. The regulation complies with pedal-assist bicycle standards, where the maximum assistance level reaches 25 km/h.

Unlocking the full potential of the PVY involves a hidden menu accessed by holding down the ‘m’ button and turning on the bicycle simultaneously. This secret menu allows users to modify settings, particularly in the P10 menu where the maximum speed can be adjusted. Setting the maximum speed above 25 km/h unlocks the accelerator, transforming it into a true accelerator with the ability to reach the maximum speed supported by the electric motor.

It’s interesting to note that once the bicycle is unlocked, the accelerator doesn’t engage when stationary. Instead, a bit of pedaling is required to gain some speed before the accelerator becomes operational. This safety feature prevents accidental acceleration from a complete standstill.

One notable advantage of unlocking the bicycle is that the accelerator doesn’t restrict the assisted pedaling. Unlike the locked mode, where the accelerator interferes with the pedal-assist function, in the unlocked state, they operate independently. This means riders can achieve higher speeds using the accelerator while pedaling with assistance.

PVY S2 Review: on the road or driving test

During the demonstration, the maximum speeds achieved were showcased in various assistance levels. With the unlocked accelerator, the bicycle reached speeds beyond the regulated 25 km/h, providing a more flexible and dynamic riding experience. It’s worth mentioning that the onboard speedometer may slightly underestimate the speed compared to GPS readings.

However, when faced with uphill climbs, the PVY S2 exhibited a limitation in terms of voltage drop, particularly when relying solely on the accelerator without pedaling. The bicycle performed well when pedaling, even on steeper inclines, but for those seeking faster speeds uphill, pedaling assistance is recommended.

PVY S2 Review: on the road or driving test

The braking system on the PVY S2 is another notable feature, featuring double disc brakes at both the front and rear. These mechanical disc brakes contribute to excellent stopping power, enhancing rider safety. However, it’s crucial to consider the smaller 16-inch wheels of the bicycle. The shorter wheelbase can make the rear wheel prone to slipping, especially when braking heavily. Riders need to exercise caution, particularly when braking at high speeds, as relying solely on the front brake might risk lifting the rear wheel and compromising traction.

The absence of gears on the PVY S2 simplifies its design and operation. While this lack of gearing contributes to the bicycle’s compact and minimalist appeal, it does mean riders have a fixed gear ratio. This characteristic can affect the bicycle’s performance, especially when tackling different terrains or varying speeds.

PVY S2 Review

The demonstration also highlighted a unique issue related to the pedals. When pedaling, the bicycle tends to push forward, and releasing the pedals abruptly causes the bicycle to stop. On the other hand, with the bicycle on and in motion, the pedals continue to rotate with the bicycle, making it challenging to bring the bike to a halt without using the brakes. This behavior could be a peculiar quirk that riders need to adapt to, potentially requiring a slightly different approach to braking.

The wetness observed on the bicycle, clarified as oil rather than water, suggests that there might be ongoing efforts to address or modify certain aspects of the bike’s performance, potentially related to the mentioned pedal behavior.

Battery and Range

The PVY S2 is equipped with a 36 V 6 Ah battery, although the manufacturer initially declares it as 7 Ah. In reality, the battery capacity is 6 Ah. This battery is the powerhouse for the 250 W motor, providing the necessary energy for an efficient and enjoyable electric biking experience.

PVY S2 Review: 6 Ah battery is approximately 4 hours when using the 1.5 A charger

Charging the battery is facilitated by a provided battery charger with a rating of 36 V and 1.5 A. The nominal voltage of the battery is 36 V, but during the charging process, it can reach a maximum of 42 V. The battery charger comes with a DC 5.5 x 2.1 connector, a less common type that users need to be mindful of when considering alternative chargers. Ensuring compatibility with the 2.1 connector is crucial for proper charging.

The charging time for the 6 Ah battery is approximately 4 hours when using the 1.5 A charger. This relatively quick charging duration allows riders to spend less time waiting for their bike to be ready for use, making the PVY a convenient option for daily commuting and short trips.

PVY S2 Review: Design and Build Quality

Regarding the range, the PVY S2 offers different possibilities based on the riding mode. When using only the accelerator, the range can vary, especially after unlocking the accelerator, which is initially set to function only as Walk Assist from the factory. In Eco mode, riders can achieve a range of approximately 20-25 km when relying on the accelerator alone. However, when utilizing pedal assistance, the maximum range extends to about 40-45 kilometers. This showcases the versatility of the PVY S2, providing options for riders to choose between a more leisurely or efficient mode depending on their needs.

PVY S2: Conclusions

So, the PVY S2 electric bicycle presents a compelling package for riders seeking a compact and efficient urban commuting solution. The 250W motor, powered by a 36V 6Ah battery, offers a good balance of performance and range. The double disc brakes provide reliable stopping power, and the option to unlock the accelerator adds versatility to the riding experience.

PVY S2 Review

The inclusion of a double key for turning the bicycle on and off enhances security, while the provided tools for assembling the front wheel and handlebars contribute to user-friendly setup, despite these components arriving disassembled in the box.

Waterproofing with an IP54 rating allows for travel in light rain, offering a degree of weather resistance. However, it’s important to note that the bike should not be left exposed to heavy rain, and immersion is not advisable.
