Comprehensive review of Vivi folding electric bike with 20-inch fat tires

Description

Introduction to the Vivi Electric Bike

Testing the Vivi Electric Bike, Model FM20UL, has been an exciting experience for me. Combining convenience, cutting-edge features, and an eco-friendly touch, this foldable electric bike offers much more than meets the eye. From its 20-inch fat tires to the removable 48V battery, it’s designed to satisfy both urban commuters and casual riders alike. I’ve used it for daily rides, and while I enjoyed many aspects, there are some considerations to share. Here’s my honest take.

Design and Build Quality

Straight out of the box, the lightweight aluminum alloy frame immediately caught my attention. Not only is it durable, but the foldable design makes it incredibly practical for those tight on storage space. Folding it is simple, and I was able to stow it away in the trunk of my car with ease. The double-walled aluminum alloy rims add to the bike’s sturdiness, and the 20-inch anti-slip tires are perfect for handling uneven roads and slippery surfaces.

The adjustable seat was another highlight for me. It accommodates a variety of heights (between 62 to 75 inches), which meant that even my taller coworker could borrow it without feeling cramped. However, weighing in at 55 pounds, it’s not the lightest bike to carry when folded, particularly for smaller riders like myself.

Performance and Speed

The bike’s 500W brushless motor was a game-changer. It delivers just the right amount of power for urban commutes, and when the throttle is fully engaged, it peaks at 750W, allowing speeds of up to 22 mph. Even when tackling hilly paths, the motor didn’t falter, which made climbing effortless. I found the 7-speed gear system to be smooth and responsive, offering versatility for both flat roads and inclines.

One feature I didn’t expect to love as much as I did was the cruise control mode. On longer stretches, it reduced the strain of constant pedaling and let me enjoy the ride. However, the motor can be somewhat noisy, especially in higher speed settings, which may bother some riders.

Removable Battery and Charging

The 48V 374.4Wh battery is built into the frame, but it’s removable, which adds a layer of convenience. Folding the bike to access the battery was straightforward, and I appreciated the anti-theft design. I could easily take the battery inside to charge it using a standard outlet. It takes about 4-6 hours to fully charge, which is fairly standard for e-bikes.

In terms of range, I managed to get around 22-25 miles in full electric mode and up to 50 miles when using pedal assist mode. This made it a reliable option for my commutes, but riders planning longer trips might need to factor in charging stops.

Key Benefits

• High-speed performance: The bike’s 22 mph max speed is ideal for quick commutes.
• Folding mechanism: This makes it easy to store and transport.
• Multiple riding modes: Choose between Ebike, Pedal Assist Bike, Normal Bike, Cruise Control, and Walk Assist.
• Shock-absorbing tires and brakes: The 20-inch skid-resistant tires and disc brakes provide a smooth and safe ride.

Areas for Improvement

• Weight: At 55 pounds, the bike is a bit heavy for carrying when folded.
• Noise: The motor can be louder than expected during high-speed rides.
• Battery accessibility: While the removable design is great, having to fold the bike every time can feel tedious.

Safety and Comfort Features

The dual suspension system ensures a smooth ride, even on bumpy terrains. I tested it on gravel paths and was pleasantly surprised by how well it absorbed shocks. The front and rear disc brakes worked flawlessly, offering excellent stopping power and control. Additionally, the bike comes with a hidden security serial number, which adds a layer of theft protection. I recommend snapping a photo of it just in case.

The LED smart meter was another thoughtful touch. It displays five speed assist levels, allowing for greater customization during rides. Switching between modes was intuitive, and I loved being able to monitor the battery level at a glance.

Competing Products

When comparing this bike to other foldable electric bikes in the market, I noticed a few key differences. Models like the Ancheer Folding E-Bike and the Swagtron EB7 Plus also offer foldable designs, but the Vivi bike’s 750W peak motor power gives it a clear edge for speed enthusiasts. Additionally, the removable battery and higher mileage range make it more versatile for commuters.

On the downside, other brands often feature lighter designs. For instance, the Swagtron EB7 Plus weighs under 42 pounds, making it easier to carry. However, those models typically lack the 20-inch fat tires, which give the Vivi bike its superior stability on rough roads.

Price to Quality Ratio

Considering the features packed into this e-bike, I’d say it offers excellent price performance. The combination of strong motor power, removable battery, and foldable design makes it a solid investment for urban riders or anyone looking for a reliable alternative to public transport. While it isn’t the cheapest option, its durability and performance justify the cost.

For budget-conscious buyers, it’s worth noting that this bike includes thoughtful extras like a tool kit and 1-year warranty for the motor and battery. I’ve seen models that charge extra for such perks, so this is a definite plus.

All in all, the Vivi Electric Bike, Model FM20UL, offers a well-rounded experience. Whether you need an efficient way to navigate the city or simply want to enjoy leisurely rides, this bike delivers on multiple fronts. While there are minor drawbacks, the positives far outweigh them, making it a strong contender in the world of foldable e-bikes.
