Vivi 27.5 Key Specs Explained

Motor Power: 500 W

This brushless hub motor provides consistent power for climbing hills and accelerating. It helps you maintain speed on steep inclines without excessive effort. You will notice a smooth ride when navigating uneven terrain or starting from a stop. This power level suits riders who encounter regular elevation changes on their routes. It is sufficient for daily commutes and light trail use. Compare this to lower wattage motors if you need more torque for heavy loads or very steep grades.

Battery Capacity: 10.4 Ah (499 Wh)

The 48V 499Wh removable battery stores energy for your rides. It charges fully in four to six hours. The removable design lets you take the battery indoors for charging, which is convenient for security and temperature control. You can charge it separately from the bike frame. This capacity supports longer trips without frequent recharging. Check this rating against other models to ensure you get enough range for your typical distance needs.

Maximum Range: Up to 50 miles

This spec indicates the farthest distance you can travel on a single charge. Actual range depends on your pedaling effort, terrain, and assist level used. Using higher assist levels or riding on rough trails will reduce this distance. You can plan longer outings with confidence, knowing the battery supports significant mileage. This range is suitable for extended recreational rides or longer commutes. Compare this figure with other eBikes to see which offers the best endurance for your specific riding habits.

Top Speed: 19.8 mph

The motor assists you up to 19.8 miles per hour. This speed aligns with Class 2 eBike regulations, which limit pedal-assist speed. You can ride comfortably without exceeding legal limits in most areas. This speed is adequate for flat paths and moderate hills. It ensures you stay safe and compliant while enjoying electric assistance. Verify local laws to ensure this speed meets your regional requirements. This limit helps you maintain control and safety during your rides.

Wheel Size: 27.5"

These wheels offer a balance between agility and stability. They roll over bumps and roots more easily than smaller wheels. The size provides good traction on loose or uneven surfaces. You will find them responsive for maneuvering on trails. This wheel size is common in mountain biking, making parts widely available. Consider this if you prefer a bike that handles off-road conditions well. Compare it with 26-inch or 29-inch options to match your preferred riding style and terrain.

Design and Build Details

The listing specifies a grey finish for this mountain bike model. You can also choose a blue option. These color choices let you pick a style that matches your personal preference. The frame is built for adult riders. This sizing ensures the geometry fits standard adult proportions for comfortable control.

You get 27.5-inch wheels. This size offers a balance between agility and stability. It helps you navigate trails with ease while maintaining momentum. The bike includes disc brakes. According to the listing, this brake style provides reliable stopping power. You can trust this system to slow you down safely on steep descents or in wet conditions.

The layout focuses on practicality. You have a 21-speed gear system. This allows you to adjust your effort based on the terrain. You can climb hills with less strain or speed up on flat ground. The controls include an LCD meter button. You use this to switch between electric assist, assisted bicycle, normal bike, and booster modes. The booster mode helps when you need to push the bike uphill without power. This design prioritizes versatility for different riding scenarios.

Setup And Daily Use Guide

You will need to assemble the bike before your first ride. The listing does not provide detailed assembly instructions, but you should expect to attach the front wheel, handlebars, pedals, and seat. Once built, you can charge the removable 48V 10.4Ah battery. A full charge takes between four and six hours. You can charge this battery anywhere you have power, which adds flexibility for your daily routine. The battery stores 499Wh of energy, giving you a maximum range of up to 50 miles on a single charge. This range depends on your riding mode and terrain. The bike features three working modes controlled by an LCD meter. You can choose pure electric mode, pedal assist, or normal bike mode. There is also a booster mode to help you push the bike up steep hills. This feature is useful if you run out of power or need to maneuver the heavy frame. You have 21 speeds to adjust your gear ratio. This allows you to fine-tune your effort on climbs or flat roads. The top speed is capped at 19.8 mph, which is typical for a Class 2 eBike. You can use the bright LED headlight for visibility during night rides. The disc brakes provide stopping power in various weather conditions. You should check the motor and battery warranty, which covers one year for main replaceable parts. Contact the manufacturer within 24 hours if you encounter issues. This setup ensures you can rely on the bike for commutes or trail rides.

Before You Buy This E-Bike

You should verify that your local laws permit a Class 2 e-Bike with a top speed of 19.8 mph. This model is designed for adult riders, so ensure the frame height suits your inseam. The 27.5-inch wheels offer a balance of agility and stability, making it suitable for varied terrain.
