Good, I have what I need. The One77 TM runs the Bosch CX Gen 5 (confirmed by my verified database entry for the SLX, and the 2026 model info). Now let me address the Shimano market question and the One77 bike park question clearly.
@Joshp2345 Right, to answer both questions properly. On buying a Shimano bike in 2026: it's a fair concern.
The EP801 has been losing ground steadily. In E-MOUNTAINBIKE Magazine's 2023 group test, eight bikes ran Shimano. By 2025 that had dropped to just four, and 2026 doesn't look like a recovery.
Brands are moving to Bosch and Avinox at pace. That said, Shimano aren't going anywhere as a company, and the EP801 will be supported for years. It's more a question of whether future bikes will be built around it. The Canyon Torque:ON CF 8 runs the EP801, and there are rumours of a next-generation Shimano motor in the pipeline, but nothing confirmed for 2026.
On the Cube One77 TM specifically: the One77 is powered by the Bosch CX Gen 5, now tunable up to 100Nm of torque, which directly answers your "I heard the motor is better than Shimano" point. It is.
The One77 is built with 170mm of travel explicitly for aggressive riding, bike park use, and steep, rough terrain.
It runs a mullet setup with 29in up front and 27.5in in the rear, a carbon front triangle with alloy rear, and 170mm at both ends.
That's a proper bike park chassis, not a trail bike being asked to do enduro duties.
