🔋 The New Transition Regulator Is A Top EMTB

Transition just dropped the Regulator CX & SX, adding two new electrified shredders to their lineup. If you’re a fan of the Sentinel, get ready—because these bikes take similar geometry and give it a Bosch-powered boost. The CX is the full-power beast, while the SX brings a lightweight approach that blends natural pedaling feel with just the right amount of assist.

Two Models, Two Personalities

🔋 Regulator CX – Bosch’s 85Nm Performance CX motor, 600Wh battery (range extender compatible), and a burly build for full-power laps.
⚡ Regulator SX – The new Performance SX motor, 400Wh battery, and a 43lb build that rides like a regular bike when the juice runs out.

What’s Got Us Stoked?

• Essentially an E-Bike Sentinel – The Regulator borrows heavily from the Sentinel’s proven geometry, with mixed wheels, 150mm of rear travel, and a well-balanced feel. If you’re already a fan of Transition’s all-mountain platform, this should feel familiar—just with an added boost.

• Adjustable Geometry – The Regulator CX includes a flip chip that allows riders to fine-tune the head angle and bottom bracket height, letting you adjust for stability at speed or a more playful ride feel.

• Shimano 12-Speed Drivetrain – Transition opted for mechanical shifting rather than wireless electronic drivetrains, keeping things affordable and dependable with Deore or XT options.

• Shorter Cranks for Technical Climbs – Both models come with compact crank arms—150mm on the CX and 160mm on the SX—helping to reduce pedal strokes and optimize efficiency, especially on steep, technical terrain.

• Bosch Flow App Integration – Riders can customize motor response, track ride data, and troubleshoot system diagnostics through Bosch’s Flow App, adding an extra layer of adjustability and ease of use.

With two distinct takes on eMTB power—the CX’s “full-throttle” approach versus the SX’s lightweight, natural ride feel—Transition is covering both ends of the spectrum. It'll be interesting to see which version resonates more with riders.
