Description

Knaap RTD X Black

De KNAAP RTD is designed for comfortable rides. With this fatbike, you're always in the right place. Whether you're riding on-road or off-road, this e-bike is ideal for a relaxed cruise.

Like the AMS, this electric fat bike reaches speeds of up to 25 km/h. The difference lies in the RTD's frame. This model is equipped with extra center shock absorption and a suspension fork, smoothly absorbing all the bumps in your path.

The Knaap RTD X is a cool, electric fat bike that is sure to turn heads on the road. This bike combines an e-bike with a trendy design and offers extra comfort. The Knaap RTD X's support comes from the rear wheel, driven by a powerful 250 Watt Ananda motor and a removable 36V/21Ah Samsung battery, allowing you to travel up to 140 km on a single charge, with a top speed of 25 km/h. The comprehensive LCD display in the center of the handlebars shows all the important information, and you can choose from 5 different support levels using the controls on the handlebars.

The Knaap RTD X is equipped with a Shimano shifting system with 7 derailleur gears for carefree riding pleasure! The bike also features hydraulic disc brakes and a comfortable two-person saddle for optimum safety and comfort. In addition, this bike is equipped with front fork suspension and an extra center suspension in the frame. With the LED lighting you remain clearly visible to others, even in the dark.

Ready to cruise comfortably on your Fatbike? De RTD X is perfect for that!
