Ride Again: The KN20S Easi Fit EBike Kit Brings New Power to Old Rides

For many people, a bicycle represents far more than just a means of transportation. It might have been a loyal companion during school days, a reliable partner for that very first job commute, or a witness to countless weekend adventures. Yet as time passes, these trusted “old friends” often end up forgotten in a corner—worn out, lacking power, or simply no longer offering the same riding experience. Throwing them away feels wasteful, while repairing them seems troublesome, and so they quietly “retire” under a layer of dust. But in truth, the story of an old bicycle doesn’t have to end there.

Today, more and more cycling enthusiasts are choosing a new way to bring their old bikes back to life—by converting a bike to an ebike with an ebike kit. With just one set of the Lvbu KN20S Series swytch bike kit, your ordinary bicycle can be transformed into a powerful, smooth, and effortless ride, beginning an entirely new “second life” on the road.

Lvbu has always been committed to making ebike conversion accessible for every bicycle, and the KN Series ebike solution was created precisely for that purpose. Unlike the bulky and complicated ebikekit conversion system commonly found on the market, the lvbu KN20S electric bicycle kit features a special bottle battery design that seamlessly integrates the bottle battery and the controller together, with only one-cable connection with the electric front wheel. This ensures high efficiency while keeping installation incredibly simple.

Whether you ride a mountain bike, road bike, folding bike, thru-axle bike, or even a tricycle, upgrading is effortless—just replace the front wheel, install the ebike kit controller and swytch battery, and your bike is ready to go. The entire process requires no specialized tools and no modification to the original frame, truly achieving the promise of “10 minutes to bring new power to your old bike.”

One user shared their experience on social media: “My bike has been with me for 25 years. I was planning to buy a new one, but a friend suggested I try the Lvbu KN Series electric cycle kit instead. I was amazed after installing it — climbing hills no longer leaves me out of breath, and the ride feels as smooth as a brand-new bike.”

The core advantage of the KN Series ebike conversion kit lies in its seamless blend of intelligence and simplicity. The assist system is based on the speed, acceleration, the slope of the road, and the assist level that you set in the APP or the optional wireless display, calculating out the power you need. The motor will kick in when the speed reaches 5km/h. When you make a little bit more effort on pedaling, the system will sense the increase of the speed and help you with more power. On contrary when you brake, the system can sense the decrease of speed and reduce the power or shutdown the motor. And thanks to the gyroscope built in the controller, it will also increase the power when you go uphill and shut down the motor when go downhill.

The KN Series swytch kit supports Bluetooth connection with the <WePower> App, giving riders full control at their fingertips. Through the app, you can monitor real-time data such as speed, mileage, and battery level, customize assist modes, and perform online firmware upgrades — keeping your fit ebike system optimized and smarter over time. This seamless connection between rider and technology transforms cycling from a purely physical activity into an experience enhanced by innovation and intelligence, making every ride both effortless and exciting.

For environmental advocates, lvbu KN20S electric bike motor kit represents more than just an ebike modification — it’s a reflection of a sustainable mindset. Instead of spending a large amount of money on a brand-new skarper ebike, why not give your old bicycle a second life with a smart electric bike conversion kit? This approach not only reduces resource waste but also preserves the sentimental bond between riders and their beloved bikes. Many users have shared similar feedback: “I was planning to buy a new ebike, but after installing the hub motor kit, I’ve fallen in love with my old companion all over again.”

When developing the KN Series bicycle motor kit, Lvbu placed great emphasis on safety and durability. The battery system is equipped with multiple protection mechanisms, including battery management, over-charge protection, over-discharge protection, short-circuit protection and temperature control, ensuring stable and reliable performance even during long rides. Whether it’s frequent stop-and-go city commuting or intense mountain riding, the lvbu electric bike kit with battery consistently delivers smooth response and lasting power.

What’s even more impressive is that the lvbu swytch ebike kit doesn’t make your bike “feel heavy.” From the very beginning, it was engineered with weight balance in mind, ensuring that your bike remains light and agile after ebike diy. For riders who often carry their bikes upstairs or need to fold and store them, this lightweight advantage makes all the difference.

And it’s precisely because of these advantages that the Lvbu e bike kits are winning the hearts of cyclists around the world. Whether it’s daily commuters looking to save energy or adventure enthusiasts chasing the joy of open-road freedom, riders everywhere are rediscovering the true pleasure of cycling through electric bike conversion system. “It helped me rediscover why I fell in love with cycling in the first place. That feeling of wind brushing past my ears, with my heartbeat matching the rhythm of the ride — it’s back again.”

The lifespan of a bicycle is often much longer than we imagine — all it needs is a touch of power to hit the road again. We believe every upgrade is more than just a technical improvement, it’s a re-connection with sustainability, innovation, and the emotions tied to every ride. Let the Lvbu electric bicycle conversion kits bring your old bike back to life, so you can once again chase the wind and the horizon.
