KNAAP RTD X - Black

KNAAP RTD X at GOfatbike

The KNAAP RTD X is the flagship model within the KNAAP line, shown here in black. It is designed for riders who want a little more: refined finishing, improved suspension, and a strong braking system. You sit comfortably upright, the motor assists smoothly, and the dark finish gives the bike a calm, luxurious look. Below you can read what the RTD X offers within the range and what to consider before you choose.

Finish and comfort

The RTD X is the most complete model in the series. The suspension is improved compared to the entry-level models, so bumps in the road are less felt in your hands and back. The finish is well done, with high-quality materials and a sleek, dark frame. You sit upright in a relaxed posture, comfortable for both short rides and longer trips. If you value comfort and a neat appearance, the RTD X is a great choice. If you’re looking for a distinctly sporty bike, the design here is deliberately more spacious and comfortable.

Range and battery

The RTD X runs on a Samsung battery chosen for a wide range. Still, the stated distance should be seen as a guideline, not a fixed number of kilometers. Your actual range depends on your weight, the wind, the support level, and the terrain. If you often ride in the highest setting or over rough terrain, the battery will run out sooner. Fully charging usually takes four to six hours, depending on how empty the battery is when connected.

Motor, speed, and regulations

The RTD X features a centrally placed 250W motor that only assists when you pedal and supports up to 25 km/h. There is no throttle, so you keep pedaling. This means the bike is considered a regular electric bike, for which you don’t need a license, registration, or helmet. Do not modify the model to go faster: you will lose the status of a regular e-bike and your warranty. The central motor position also ensures a balanced weight distribution across the bike.

Tires, brakes, and riding experience

The advanced braking system of the RTD X provides strong grip on the brake and brings you to a controlled stop, even in wet conditions. The wide tires offer stability and perform well on various surfaces, from streets to unpaved paths. You shift gears with a Shimano system, convenient on flat stretches and climbs. Lighting is front and rear, with an LCD display with USB port on the handlebar. Expect a solid total weight, something to consider when lifting or storing.

Who is this model for

The RTD X is designed for those who want the most complete KNAAP model and are willing to pay a bit more for comfort and finish. You mainly buy it for the improved suspension, strong braking system, and refined appearance. It’s a great choice for daily rides, longer trips, and comfortable cycling. If you’re looking for a simple, lightweight model or a bike with a low step-through frame, other models in the range will suit you better.
