The journey of finding the right e-bike wasn’t a simple one for me. Living in a bustling city where space is at a premium and getting around can be a challenge, I started looking for an e-bike that could adapt to my needs. My daily routine involves commuting through busy streets, navigating through traffic, and sometimes even combining different modes of transport like buses or subways. An e-bike seemed like the perfect solution, but it wasn’t just any e-bike that would work—I needed something compact, easy to store, and still powerful enough to handle my various demands.
Folding e-bikes were an obvious choice. The ability to quickly collapse the bike into a more portable form meant I could bring it onto public transportation or easily stash it in a small apartment. After researching different models and brands, the Tern Vektron S10 caught my eye. It wasn’t the cheapest option, but it stood out due to its well-rounded features, reputation for quality, and robust Bosch motor. This bike promised a balance between convenience and power that I was hoping for.
Tern as a brand has built a solid reputation in the cycling community for their focus on urban mobility solutions. They specialize in bikes that are practical for city dwellers, which made me confident that the Vektron S10 could meet my expectations. With that in mind, I was eager to put it to the test and see if it could deliver on the promises of versatility, ease of use, and power. Here’s a detailed look at my experience with the Tern Vektron S10, starting with its key features.

That Make the Tern Vektron S10 Stand Out
The Tern Vektron S10 packs several features that make it stand out from other folding e-bikes. Whether you’re commuting, carrying kids, or using it for errands, these elements make the bike a top contender in the urban e-bike market.
Bosch Performance Electric Drivetrain
One of the standout features of the Tern Vektron S10 is the upgraded Bosch Performance drivetrain. This powerful motor offers up to 300% assistance and generates 65 Nm of torque, which makes a huge difference when riding uphill or carrying heavier loads. The Bosch motor is known for its reliability and durability, and this was evident in the Tern Vektron’s performance. When I hit steep inclines, I could feel the motor kicking in, providing that extra push that makes e-bikes such a great option for urban commuting.
The Bosch system also comes with multiple riding modes, allowing you to control the level of assistance based on your needs. Whether you want to conserve battery or take it easy on a tough ride, the Bosch Performance motor is up to the task. In my experience, this flexibility made a significant difference in how the bike handled different situations.
Folding Design and Portability
The ability to fold the Vektron S10 is a huge selling point. The OCL+ hinge design is robust and feels solid when folded or unfolded. What I appreciated about the folding mechanism is that it’s intuitive and quick to use. I didn’t need to fumble around to figure out how to collapse the bike—it took just a few seconds.
This feature is especially important for those who, like me, might need to switch between cycling and public transportation. Whether it was folding the bike to take on a bus or storing it in a small corner of my apartment, the compactness and portability of the Vektron S10 are a big plus. The bike folds into a compact size, making it easy to carry onto a subway or a taxi when needed.
Battery Performance and Range
The Vektron S10 is equipped with a Bosch 400 Wh battery, which provides enough juice for long-distance commutes. Tern claims a range of up to 100 km (62 miles) on a single charge, and during my tests, I found that this estimate is quite accurate depending on the terrain and level of motor assistance. For my typical commute, which includes a mix of flat roads and some hills, I didn’t have to worry about running out of battery for several days.
Charging the battery was also quick and convenient. From zero to full charge, it took around 3 to 4 hours, which means it’s easy to charge overnight or during the workday if needed. The battery is removable, making it simple to take indoors for charging, and its placement on the bike, reclining along the frame, keeps the center of gravity low for better stability while riding.
Safety and Braking
Safety is always a priority, especially in an urban setting where traffic can be unpredictable. The Tern Vektron S10 features hydraulic disc brakes that provide excellent stopping power, even in challenging conditions like rain or on slippery surfaces. I found the brakes to be responsive, requiring only a gentle pull to bring the bike to a stop.
What sets these brakes apart is that they use mineral oil-based brake fluid, which is not only more environmentally friendly than other hydraulic fluids but also easier on the bike’s braking system in the long term. The brakes, combined with the stable frame design, gave me a lot of confidence riding through city streets, even in wet conditions.
Resizing for Multiple Riders
One of the most impressive aspects of the Tern Vektron S10 is how quickly and easily it adjusts to different rider sizes. The bike can be resized in seconds to accommodate riders between 4’10” and 6’5”, which makes it a fantastic option for families. In my household, we tested this out with different people, and the bike adjusted effortlessly to each person’s preferred setup.
The handlebar height and seatpost can both be adjusted without the need for any tools. This is a huge benefit if you’re sharing the bike with someone else, as you can quickly resize it before heading out. In my experience, this versatility made the bike feel even more practical.
Atlas V Rack
The rear rack on the Vektron S10 is another thoughtful addition. The Atlas V Rack is sturdy and compatible with child seats like the Thule Yepp Maxi or Dash RM, making it a great choice for parents who need to transport their kids. What I appreciated about the rack is that no adapters are required to use these child seats, which simplifies the setup.
In addition to carrying children, the rack can handle up to 27 kg (59 lbs) of cargo, so it’s also useful for carrying groceries, bags, or panniers. I’ve used it to carry shopping bags, and the bike still handled well, without any noticeable wobble or loss of balance.

A Day in the Life with the Tern Vektron S10
When it comes to performance, the Tern Vektron S10 truly shines. After putting the bike through its paces on different terrains and conditions, I can confidently say it’s built to handle a variety of scenarios, from daily commutes to weekend rides.
First Ride Experience
My first ride on the Tern Vektron S10 was on a typical urban route—flat roads mixed with some hills and a bit of light traffic. Right from the start, I could feel the motor’s power, particularly when I needed that extra boost to climb inclines. The ride was smooth and comfortable, even when navigating through narrow, congested streets. The bike’s balance felt perfect, thanks in part to the low center of gravity created by the reclining battery.
Handling and Maneuverability
The Tern Vektron S10 handles very well, both in tight city spaces and on open roads. The adjustable Andros stem lets you quickly change the handlebar height and angle, allowing for a more relaxed, upright position when cruising around town or a lower, more aggressive stance for faster rides. I used both settings depending on how I was feeling and found the flexibility incredibly convenient.
Maneuvering through tight spaces and making sharp turns was a breeze. Despite being a foldable bike, the Vektron S10 felt stable and responsive at all speeds. Even when I hit bumps or uneven surfaces, the bike absorbed the shock well, keeping the ride comfortable.
Power and Torque
The Bosch motor shines when you need to tackle hills or carry extra weight. I tested the bike on a few steep inclines, and the motor provided ample torque to get me up without too much effort. The transition between pedal power and motor assistance felt smooth and natural—there were no sudden jerks or surges when the motor kicked in.
The multiple riding modes also allowed me to conserve battery on flatter terrain. In eco mode, I still had enough assistance to take the edge off pedaling, but it didn’t drain the battery too quickly. Turbo mode, on the other hand, was perfect for when I needed that extra burst of speed or when I was carrying more weight on the rear rack.
Comfort and Ergonomics
Comfort is key, especially on longer rides, and the Vektron S10 doesn’t disappoint. The Andros adjustable stem made it easy to find the perfect riding position, whether I wanted to sit upright for a leisurely ride or adopt a more forward-leaning stance for speed. The saddle was also surprisingly comfortable for a stock option—I didn’t experience any discomfort even after longer rides.
The bike’s geometry feels well thought-out, and combined with the sturdy frame, it provides a smooth, comfortable ride. I also appreciated the ergonomic grips, which helped reduce hand fatigue, especially on longer rides through the city.
Battery Life and Charging
Real-world battery performance lived up to expectations. On a full charge, I could comfortably ride for about 70-80 km (43-50 miles), even in a mix of turbo and eco modes. While this is slightly below the maximum advertised range, it was more than enough for daily commuting and errands. I also found that if I was cautious about how I used the motor, I could stretch my rides even longer by switching to lower assistance modes on flatter stretches.
Charging the battery was also a hassle-free experience. I typically charged it overnight, and it was ready to go by morning. The removable battery design is a standout feature, allowing me to easily take it indoors to charge without needing to bring the entire bike inside. Overall, the battery life and charging capabilities of the Tern Vektron S10 made it a practical choice for my daily needs.

The Tern Vektron S10 in Different Scenarios
The true test of any e-bike is its versatility. The Tern Vektron S10 has proven itself in a variety of situations, from family outings to solo adventures, showcasing its adaptability.
Family Friendly Features
As a parent, one of my biggest considerations when choosing an e-bike was how well it could accommodate family needs. The Atlas V Rack makes it easy to attach a child seat, allowing me to take my little one along for the ride. This was a game-changer for family outings, as I could easily switch from carrying groceries to transporting my child without needing to switch bikes or spend time on complicated setups.
I also appreciated the bike’s ability to resize quickly for different riders. My partner, who is taller than I am, was able to adjust the bike in just a few seconds, making it easy to share the bike. This adaptability is essential for families who might have varying heights and preferences for riding positions.
Commuting Convenience
For daily commuting, the Tern Vektron S10 has been a fantastic ally. It’s compact enough to fit into tight spaces, making it easy to store in my office or take on public transport when necessary. I’ve found that folding it up to fit onto buses or subways is simple and efficient, which has made my commute much more enjoyable.
The stability and comfort of the bike allow me to navigate through busy streets with confidence. I’ve even taken it on longer rides into the city, where I appreciated the power of the Bosch motor and the reliability of the brakes while dodging traffic and pedestrians.
Weekend Adventures
On weekends, I’ve enjoyed using the Vektron S10 for leisure rides. Whether it’s a relaxed ride along the waterfront or an adventurous outing on mixed terrain, the bike performed well. Its ability to switch between different riding modes made it versatile for varying terrains, from flat paths to moderate hills.
I also took it on a couple of longer rides with friends, and everyone was impressed with its performance. The bike handled well, and the power-assisted riding made it easy for everyone to keep up, regardless of their fitness levels.
Keeping Your Tern Vektron S10 in Top Shape
Like any bike, the Tern Vektron S10 requires regular maintenance to keep it running smoothly. Thankfully, the design and components of this bike make it relatively easy to care for.
Basic Maintenance Tips
I found that keeping the bike clean is essential, especially since I often ride in urban environments where dust and grime can accumulate. A simple wipe-down after rides helps maintain its appearance and functionality. Additionally, I’ve made it a point to check the tire pressure regularly to ensure optimal performance.
The hydraulic disc brakes require minimal maintenance, but I do keep an eye on the brake pads to ensure they are not worn out. The Magura Easy Bleed Technology makes it simple to maintain the hydraulic system, which is a relief since it means I can handle basic upkeep without needing to visit a bike shop frequently.
Battery Care
The Bosch battery is designed for longevity, but there are some tips I follow to keep it in good shape. I avoid completely draining the battery whenever possible and try to recharge it when it gets to about 20%. This practice seems to help extend its lifespan, and I store the battery in a cool, dry place when I’m not using it for extended periods.
I also pay attention to the battery connections, making sure they’re clean and free of debris. This small effort goes a long way in maintaining the bike’s performance.
Is the Tern Vektron S10 Worth It?
