News for 2024

For 2024, we’ve improved the battery capacity and the look of the Apes EER4 with a new luggage rack. And we’ve refreshed the bike’s aesthetic appeal with new colours, a refreshing Papyrus White and a charming Antrancit Grey.

Propulsion and energy

Rear-wheel drive systems Shengyi often provide a smooth and efficient power transfer, making for a more natural driving experience. The engine directly drives the rear wheel, allowing responsive and powerful acceleration. Rear-wheel drive systems can be easier to maintain as there are fewer components compared to some mid-drive systems. The bike is equipped with an Econo battery, which is the result of our own development and is manufactured in our own centre. It is easy to handle. You can choose the capacity of the battery yourself.


The Apes EER4 is equipped with reliable TEKTRO mechanical disc brakes that allow safe and fast braking and stopping. They transmit high forces and work the same in all weathers. Be seen and increase your safety and time on the bike with front and rear led lights.


The bike is equipped with a stem adjustable in height and also in inclination, so you can adapt it to your needs and feel as good as possible on the bike. It has fenders that protect you from water and dirt in bad weather. Thanks to them, we stay dry and clean regardless of the terrain. You will be able to place luggage in the trunk during the day’s purchase. The bike also has a strong bike support. As a novelty on the bike, we added a lock attached to the bike for quick locking of the bike.
