The dedicated mixed-wheel platform with 150mm rear and 160mm front travel make the Regulator CX nimble and responsive while delivering powerful assistance for the steepest of climbs. With a 64.5 degree headtube angle and short, 27.5" wheel specific chainstays, we were able to make the Regulator one of the most maneuverable eMTBs we've ever ridden. This keeps the ride fun and engaging on everything from smooth flow trails to steep tech. A geo adjust chip in the lower shock mount allows riders to fine tune geo to their preferences.
The Bosch CX system delivers the highest power-to-weight ratio possible. Perfect for riders who want lighter ride characteristics from their eMTB that excels in a wide variety of terrain. Complete builds come in at just over 47lbs while still delivering 85Nm of torque for powerful assistance.
Powered by the Bosch CX system, the Regulator gets the legendary reliability of Bosch in a lightweight package giving you 85nm of torque and 600w peak power. While powerful, the system also provides an incredibly natural feel that delivers power without breaking traction, keeping your momentum and helping you clear technical trails.
Enclosed low in the downtube is Bosch's 600wh battery. It's perfectly sized to provide range for big rides without compromising ride characteristics, the 600Wh battery provides the best range-to-weight balance.
Head deep into the backcountry with the additional PowerMore 250wh range extender. Custom cable management keeps the connection clean and secure.
Easily control the power modes and view battery life via the wireless Mini Remote and slim System Controller top tube display. This minimal display keeps you focused on the trail ahead, while providing all the necessary info you need to keep riding. Giving you everything you need, and nothing you don't.
For those looking to dig into the settings, the Bosch Flow app gives you full control and customization. Once paired with your Regulator, you can adjust the power level support and peak power from the convenience of your phone without any wires or a laptop.

![]() ![]() GIDDYUP SUSPENSION DESIGN ![]() We want to make it as easy as possible to experience great rear suspension performance. The GiddyUp suspension system is designed to behave intuitively across a broad range of setup. Because, we get it, sometimes you just want to grab your bike and GiddyUp, without checking your setup. ![]() This translates to supple small bump compliance and great mid-stroke support that gradually transitions into a subtle, yet supportive end-of-stroke ramp. The amount of consistent progression is carefully optimized for both air and coil shocks. Riders are able to add or remove volume spacers in air shocks to suit their individual riding style. The Regulator has 150mm of rear wheel travel when used with the supplied 205mm x 60mm stroke shock. It is also possible to install a longer stroke shock of 205mm x 65mm to increase the rear wheel travel to 160mm. A wide usable sag range of 27-33% allows the rider to tune the feel of the bike; from poppy and playful, to planted for plowing. Wherever you end up, you can focus on the trail without remotes, levers or knobs. Just grab your bike and GiddyUp. | ![]() |
