Climbing, descending, and covering long distances? If that's your style of mountain biking, we have something special for you: the Reaction Hybrid SLT 800. Equipped with the powerful Bosch CX motor, Kiox 500 display, and an integrated 800 Wh battery, this e-MTB provides the power and range to tackle any challenge. A wireless 12-speed X0 Eagle AXS Transmission drivetrain efficiently and flawlessly transfers all that power to the rear wheel. And you can always rely on the powerful Magura Gustav Pro hydraulic brakes. A stiff, air-sprung Fox 34 AWL suspension fork keeps the sturdy Newmen wheels grounded, offering excellent control. The Smart Sam 2.6 inch tires from Schwalbe provide comfort and grip. Super practical is the dropper seatpost, which allows you to easily lower the saddle on challenging trails. There’s no better way to expand your horizons.
A significant performance boost for compatible CUBE bikes fitted with selected BDU38 Performance Line motors will be available from 4 May 2026. The upgrade is available simply by using the Bosch eBike Flow App. No other action is needed.
After downloading Performance Update 2.0 via the eBike Flow app, you can now choose to increase these peak values up to 120Nm torque , 600% support and 750 watts, with peak power also available for longer periods depending on riding conditions.
Maximum rider support of up to 600% is limited to speeds between 0 and 15km/h (this doesn't affect the speed limit of 25km/h for pedal assistance, which remains the same). Some trekking and city bikes equipped with hub gears may have lower performance increases to remain within manufacturer recommendations.
More boost. More precise control. Performance, redefined.
