The Tern Vektron S10 is robust and stable, providing a truly sturdy riding experience even when fully loaded, with a comfortable feel. Additionally, it’s convenient for transport and storage when folded.

Next, we’ll analyze the riding experience, key features, components, and specifications of the Tern Vektron S10. In the latter part of this article, we’ve also compared it to a few other bikes. If you’re interested in more bike reviews, be sure to follow us.

Riding Experience

The Tern Vektron S10 boasts an ergonomic riding posture, making the ride comfortable. Its easy folding feature allows for quick storage and transport.

I planned to use the Tern Vektron S10 to explore nearby attractions and booked a hotel through IHG in advance. The route for the ride was mostly flat but included some uphill and downhill stretches. Overall, it was a smooth and comfortable riding experience.

Road Riding

When riding the Tern Vektron S10, I found it provided a comfortable pedaling experience. The overall riding position kept me upright throughout. The soft saddle and ergonomically designed handlebars ensured comfort for my lower back. The handlebars fit my hands snugly, preventing slipping.

The excellent Bosch motor offered powerful and smooth assistance, maintaining a quiet operation, making pedaling more effortless and energy-efficient.

Shifting gears with the Shimano Deore gear system was quick and precise, allowing me to switch to the desired gear swiftly. This feature came in handy during uphill rides, making the journey easier and less physically demanding.

I particularly appreciated the braking system on this electric folding bike. The Magura hydraulic disc brakes delivered strong braking performance, allowing for quick deceleration. Even during continuous braking on downhill sections, there was no overheating, and the braking capability remained efficient.

In conclusion, riding this electric folding bike offered a comfortable overall experience. The components were reliable, ensuring efficient and speedy rides.

Is That It?

The Tern Vektron S10 electric bike is also suitable for commuting. Firstly, the bike’s frame is durable and reliable.

Furthermore, the 20-inch wheels, combined with Schwalbe Big Apple tires, make the bike highly maneuverable, allowing for agile navigation through city streets. The excellent tire traction and grip remained effective even on wet roads, and they were resistant to punctures when encountering bumps.

The integrated front and rear fenders kept the rider from getting splashed with water from the road, helping to maintain a clean and neat appearance during rides.

In summary, this is a versatile electric folding bike suitable for recreational riding and offers a reliable commuting option with multiple riding modes.


The Tern Vektron S10 comes in one frame size, but its low-step frame design allows for easy size adjustments in seconds without the need for tools, accommodating riders between 147 to 195 centimeters (4’10” – 6’5″). This means you can share the bike with family members, providing wide-ranging versatility.

Equipped with Bosch’s high-performance motor, it can achieve speeds of 25 kilometers per hour. It offers a quiet ride and reduced pedal resistance, making cycling more relaxed and effortless.

The Shimano Deore transmission system provides precise and quick gear shifting, ensuring high transmission efficiency. The Magura hydraulic disc brakes offer all-weather braking capability, delivering reliable performance even in adverse conditions.

Other Versions

The Tern Vektron S10 is an excellent electric folding bike, known for its reliability and power, but it comes with a higher price tag. For budget-conscious riders, there’s another version that retains the same excellent features.

The Tern Vektron Q9 also uses Bosch’s high-performance motor with equally impressive power output and extended battery life.

The main differences lie in the transmission and braking systems. It features the Shimano Alivio 1×9-speed transmission, which is slightly lower in grade and not as smooth in operation as the Shimano Deore but remains reliable. The Shimano hydraulic disc brakes have slightly less braking power compared to the Magura but are sufficient for everyday riding.

In summary, this electric folding bike is reliable and suitable for everyday use, especially for budget-conscious riders.


What do we like about it?

  • Sturdy, durable, and easy-to-maintain components, including the patented Andros stem, Physis 3D handlebars, and OCL+ frame hinge.
  • Equipped with Bosch power packs, offering a range of up to 130 kilometers. The battery can be locked in place to prevent theft or easily removed for indoor charging.
  • Integrated front and rear lights for improved visibility and safety. Lights are connected to the Bosch battery, eliminating the need to detach them for charging.
  • The Vektron features a robust integrated frame that can carry up to 27 kilograms, allowing for greater load capacity during rides.
  • Designed for easy maintenance and safety from the ground up, resulting in a reliable vehicle that can be used day after day.
  • Supported by high-quality local service and a 10-year warranty, providing peace of mind for riders.

What don’t we like about it?

  • Expensive price point, not a universal choice.


  • What is the maximum load capacity of this bike?

The Bosch-equipped Vektron can take you up to 25 kilometers per hour.

  • Is torque important for electric bikes?

In electric bikes, torque refers to the ability to rotate the rear wheel. Higher torque will result in greater acceleration, making it easier to start from a stop or climb steep hills. This means bikes with higher torque are better for starting from a stop or tackling inclines.

  • How do I choose the right size?

We provide a size chart here, but it’s not a strict standard. The best way to find the right size is to test ride the bike.
