Product Description
2025 THOK TP4 - S MOUNTAIN BIKE
EXCELLENCE, VERSATILITY, INNOVATION.
The TP4-S is the bridge between all-mountain and enduro.
Engineered, designed and tested in Italy like the rest of the THOK range, it was created to conquer the most extreme climbs, while maintaining the downhill performance attitude typical of the brand’s DNA.
It features a UD carbon frame (travel: 160mm front / 150mm rear), Bosch Performance Line CX motor, 800 Wh modular battery, FOX Float 36 Performance fork, FOX Float X shock, Magura MT5 brakes, 29” wheels (compatible with mullet setup), and the use of Flip-Chip technology, which allows adjustment of the seat tube and head tube angles, and consequently, the bike’s behavior, adapting it to different riding styles and terrains.
NOMEN OMEN
TP4 stands for THOK Project Four and it is the name given to the project by the R&D department when it started this study. “S” indicates the premium components it’s equipped wiyh. The TP4 is the world’s first carbon full-suspended e-bike for which 3D printing technology was used to create the first functional prototype.
This is the 5th generation of the Bosch drive units, featuring:
• weight of only 2.8 kg
• 100 Nm max torque, peak of 750-Watt motor power
• smoothness of delivery and predictability of response
• up to 400% pedalling amplification
• maximum silence
• 1.6-inch Purion 200 colour LCD display
• six-dimensional inertial sensor to recognise unevenness and slope of terrain
• Walk Mode: with integrated hill-hold function
Modular 800 Wh battery
The TP4-S 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-S 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-S meets the needs of every rider.
WEIGHTS:
800Wh battery → 24,3 kg

400Wh battery → 22,1 kg
