Jason+ the test winner

Following the success of the Jason+ in 2023, which was hailed as "Best Buy of the Year" in the unisex category by, Momas is now taking another step forward with the launch of the Jason+ 2024. Tekguide's in-depth e-bike test also endorsed the Jason+ and shared their insights and experiences of the bike. You can read the full text at to get a more detailed insight into why it was named best in test in 2023.

The upgraded model takes the e-bike experience to new heights with a range of improvements. The Jason+ 2024 is powered by the impressive Momas Ultra 70 motor, providing even more powerful acceleration and a better riding experience. With improved brakes and small but significant adjustments to the handlebar, we've fine-tuned the details to create an even more optimal user experience. The upgraded model retains the essence of Jason+ as an affordable and easy-to-use e-bike, perfect for adventures on gravel roads and asphalt alike.

Powerful crank motor with torque sensor

The mountain bike has an adjustable suspension fork and lightweight aluminum frame. It has a powerful Momas Ultra 70 crank motor for a comfortable experience in the saddle. The motor is center-mounted and will operate at optimal rpm at all times. The center-mounted motor is indisputably the best motor system for electric bikes, with the most advanced technology and innovation. The torque sensor is a more advanced, and therefore more expensive, technology. It delivers motor power according to how much force you put into pedaling.

The fact that it's unisex makes it easy for multiple family members to use the bike. Momas continues to set the standard with the Jason+ 2024, and we invite you to experience a new dimension of e-biking. Explore the roads with strength, control and unparalleled ease of use.

The range from a battery charge will vary depending on various conditions. Factors that affect range are the combined weight of the rider and load; wind resistance; tire pressure and tire tread; terrain and elevation changes; surface conditions; temperature; e-bike maintenance; and the condition of the battery.
