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.
