Product Description
2025 THOK TP4 MOUNTAIN BIKE
Performance and quality
The TP4 is completely designed in Italy as are all models in the THOK range.
UD carbon fiber frame (travel: front 160mm / rear 150mm), Bosch Performance Line CX motor, modular 800 Wh battery, FOX Float Rhythm 36 fork, FOX Float Rhythm shock absorber, 29” wheels (mullet trim compatible) and use of Flip-Chip technology, which allows variation of seat tube and head tube angles, and consequently of the bike’s behavior, adapting it to different riding styles and terrains.
A boosted all-mountain that winks at enduro, created to conquer the most extreme climbs while maintaining the performance downhill attitude typical of the brand’s DNA.
The TP4 is a very versatile and value-for-money vehicle designed to enable everyone to equip themselves with a superior vehicle.
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. 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.
Bosch Performance Line CX (BDU384Y)
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 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 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 meets the needs of every rider.
WEIGHTS:
800Wh battery → 24,3 kg
600Wh battery → 23,2 kg
400Wh battery → 22,1 kg
