TP4-SE is designed to deliver control, power, and maximum versatility on any type of terrain.
It shares with the TP4 and TP4-S the full unidirectional carbon fiber frame, the Flip Chip geometry adjustment system, 160 mm front travel and 150 mm rear travel, and the Bosch Performance Line CX motor, paired with the integrated 800 Wh battery, compatible with an optional 250 Wh range extender.
The system is completed by the BOSCH – KIOX 400C display for simple and immediate ride data control.
What mainly distinguishes this model is the SRAM S1000 AXS T-Type electronic drivetrain system, ensuring fast and precise shifting even in the most demanding situations.
The setup is completed by the FOX 36 Float Performance fork, FOX Float X rear shock, MAGURA MT5 4-piston braking system, DT Swiss H1900 29” wheels, and Schwalbe Magic Mary Evo Super Gravity 29×2.4 Soft front tire/ Schwalbe Big Betty Evo Super Gravity 29×2.4 Soft rear tire.
The TP4-SE stands out for its refined Royal Black finish, enhanced by the exclusive silver-colored rocker and yoke.

TP4, acronym for “THOK Project Four”, is the name chosen by the Research & Development department to mark the beginning of a new design path. The TP4 is the first full-suspension carbon e-bike for which metal 3D printing technology was used to create the first functional prototype.
TP4-SE represents a version of the range characterized by a specific build, designed to offer an optimized balance between performance and technology, while keeping the DNA and core characteristics of the TP4 unchanged.
The TP4-SE is highly versatile and modern in its use: its adaptable geometry makes it suitable both as an all-mountain and an enduro bike. The Flip Chip system allows riders to adjust the head angle, the seat tube angle, and lower the bottom bracket, making it a fun adventure companion on downhill trails, including very rough ones, and suitable for different terrains and riding styles.
This is the 5th generation of the Bosch drive units, featuring:
The TP4-SE is available with an integrated 800 Wh battery housed inside the down tube.
The system is compatible with 600 Wh and 400Wh batteries thanks to the “slide battery” system, the inner carbon battery cradle designed to enhance the seat tube and store the batteries with lower capacities by placing them downward, close to the motor, to secure the low centre of gravity that is typical of the range.
It is possible to purchase the TP4-SE with a 400Wh or 600Wh battery. In this case, the biker chooses a lower autonomy in return of weight saving.
The system (equipped with any battery capacity) is also compatible with the addition of ‘PowerMore’, the plug & play 250 Wh range extender from Bosch.
There are no limits to the possible battery capacity combinations: the TP4-SE meets the needs of every rider.
