1. How durable is the carbon frame of the Carbon Classic ST Electric City Bicycle?
The Carbon Classic ST is a premium urban e bike built with high-quality Toray T700/T800 carbon fibers and advanced EPS molding technology. This process creates a lightweight yet exceptionally strong and impact-resistant frame with a smooth, seamless interior that eliminates stress points. The result is a precisely engineered structure that offers the same reliability and performance you would expect from top-tier racing bikes, making it perfect for everyday city rides and long-term durability.
2. What is the difference between a hub motor and a mid-drive motor?
Hub motors are generally lighter, smoother, and more responsive, making them ideal for city ebike rides and gravel roads. Mid-drive motors, on the other hand, deliver better performance on steep climbs but tend to be heavier, noisier, and more complex. The Carbon Classic ST and Carbon Classic eBike are designed for urban and gravel environments and feature a hub motor to provide an agile and effortless riding experience. For riders who often face steep hills, our Fusion models offer a powerful alternative.
3. Is the handlebar adjustable?
Yes, this bike comes with a 60° adjustable handlebar that allows the rider to achieve the desired riding position

Yes, the Carbon Classic ST is designed to perform reliably in all weather conditions. With an IP65 rating for dust and water resistance, it protects you from rain and splashes. Its frame accommodates tires up to 45C wide, providing excellent stability and traction on wet, uneven, or rough surfaces. Whether riding through rain, dust, or challenging terrain, the Carbon Classic ST delivers a confident and dependable ride.

Originally this was “my bike.” That lasted about two weeks.
My husband started borrowing it for evening rides and now we both use it regularly.
The step-through design makes sharing easy.
We’ve both noticed we’re riding more often and farther, mostly because it doesn’t feel like a chore.
My doctor told me to stay active, but walking always made my hips sore. This bike changed my whole routine. I ride with my husband in our neighborhood every afternoon. The step through frame makes it easy to hop on, and I feel steady and safe. For someone who hasn’t biked in decades, this feels like freedom.
I bought the Classic ST as a holiday deal and I’m loving it. The step-through frame makes it easy for me to get on and off. I ride it to the park with my grandkids and even join them on small trails. My doctor told me to stay active, this bike made that actually enjoyable!
Bought this for my 68-year-old mom who struggles with knee pressure. The step-through design gives her perfect balance and comfort. She rides every morning to the beach near our home in Florida. She said she feels “young again.” The calm rides improved her sleep and mood. Best purchase I’ve made for her health and happiness.
My wife isn’t a strong rider and hates heavy e-bikes. The Classic ST looks chic, weighs way less than others we tested, and she feels super confident stepping through. We now do Sunday morning rides to the farmer’s market together, she keeps saying she can’t believe how easy it is.
