Description
With its Gram, THOK E-Bikes enters the high-performance carbon world: with carbon fibre, you can create many different, complex shapes and harness your creativity.

THOK PROGRESSIVE SYSTEM 2
The new TPS-2 suspension system designed by THOK E-Bikes increases the progressivity of the kinematics and optimises its use in Enduro.
SHIMANO SYSTEM – THE CHOICE
- The progression of a motor is how it delivers assistance: Shimano does not have peaks. It feels like a well-trained leg
- How elastic a motor is is determined by the transition between the push and release phases: with Shimano, it is constant and manageable
- The Q factor (the distance between the cranks) of the EP8 motor is lower: pedalling is more natural
- The EP8 is one of the lightest and least bulky motors you can find; it has a small and intuitive display, it can be customised and store parameters
- Shimano has one of the best-structured assistance services in the world: always precise and responsive
- The Shimano closed system (motor, battery, software) guarantees maximum efficiency when it comes to performance and consumption
PERFORMANCE FIRST – SHIMANO EP8 CLOSED SYSTEM WITH 630 WH BATTERY
Performance is the number one priority in every THOK project. The Gram is equipped with the closed Shimano EP8 system because it guarantees maximum efficiency when it comes to performance and consumption. Tests carried out by the in-house research department have proven this, here are the results:
