Last summer’s 3D-printed aluminum Project 4 eMTB is reborn as the now-carbon Thok TP4, a full-power all-mountain ebike that retains modular batteries so you get only the juice you want and no extra weight. Thok’s first Bosch eMTB gets fitted with the latest CX motor update, and the option for anywhere from 400Wh-1050Wh batteries to suit each buyer’s style of riding.,
Thok TP4 Italian carbon all-mountain ebike
Last year at Eurobike Thok teased us with Project 4, what they called the world’s first 3D-printed alloy full-suspension ebike.
Now, it turns out that modular eMTB project was simply the rapidly-developed test bed for Thok’s first ebike with a Bosch CX motor.
And what was made quickly with additive manufacturing in aluminum to dial in the shaping and geometry, is now being made entirely in Italy out of carbon fiber.
The new Thok TP4 is mid-travel 29er eMTB with 150mm of 4-bar rear wheel travel mated to 160mm up front. Thok calls it “enhanced all-mountain with an enduro side to it“. While building an all-new made-in-Italy eMTB platform around the new lighter, smoother, and quieter Bosch Performance Line CX motor, Thok wanted to create a technically-capable do-it-all-mountain ebike that riders could tailor to their needs with the precise battery size that they needed.
Modular battery size was a key point of the original 3D-printed project bike. And they carry that on here with an adaptable battery cradle inside the downtube that can secure 3 sizes of batteries behind the removable battery cover/downtube protector.
Slacker geometry for all-mountain eMTB versatility
Compared to Thok’s shorter travel all-mountain MIG (140/150mm) and longer-travel e-enduro TK01 (170/170mm ), the new TP4 is actually as slack or slacker than either. Thok says that was about bridging the gap between the two, while creating and even more versatile all-mountain ebike capable of riding any terrain.
Start off with a 64.5° headtube angle, 79° seattube, 459mm chainstays, and 477mm size L Reach.
And thanks to the Hi/Lo flip-chip at the forward shock mount, riders can further slacken the geometry by 0.5° (and lower BB height 9mm). Or even run it in the Hi position with a 27.5″ rear wheel for a slacker mullet conversion.

Thok TP4 ebikes – Pricing, options & availability
The new carbon Thok TP4 eMTB comes in 2 complete ebike builds – both of which come standard with the big 800Wh battery. But all buyers can opt for a smaller battery if they want, to save both money and weight.
The TP4-R is the ‘more affordable’ option at 7190€ with Fox 36 & Float X Performance suspension, a mechanical XT drivetrain, 4-piston Magura MT5, and then alloy DT H1900 wheels wrapped in the great new Schwalbe Albert Gravity Radial tires – at a claimed 24.3kg complete (size M).
The much more expensive 10,490€ TP4-LTD steps it up to Öhlins RXF36 fork, TTX2 Air shock, SRAM GX Eagle electronic T-type derailleur wired into the ebike’s battery, Magura MT7 brakes, and carbon DT Swiss HXC1501 wheels with those Schwalbe Albert Gravity Radial tires – at a claimed 24.1kg. The LTD is also actually a limited edition, and Thok only make 30 of them.
And if you prefer a smaller battery for either model, you can pick the smaller 600Wh option to then save 1.1kg & 200€, or get the lightest 400Wh battery to save 2.2kg & 400€ vs. the standard big battery setups.
Both versions are technically available to buy now. But Thok sold out the first small batch, so the next delivery comes next month in December.
