Trek Rail 9.9 XX1 AXS Lava 750Wh

The Rail 9.9 is our best long-travel e-mountain bike. You get an extremely robust carbon frame, an incredibly smooth RockShox suspension, SRAM's best wireless electronic drivetrain, and Bosch's powerful Performance Line CX motor with a particularly long-range battery and the new Mini Remote. The new System Controller is almost flush-mounted into the top tube for a clean look and is never in the way, even during tough rides.

Trek offers you a redesigned frame made of OCLV Mountain Carbon with longer reach, as well as oversized head tube and seat tube for maximum stability. Additionally, there's an extremely long-range 750 Wh battery, a highly customizable RockShox ZEB Ultimate fork, a RockShox Super Deluxe Ultimate Thru Shaft shock, and a SRAM XX1 AXS drivetrain. You also get Bosch's Smart System Performance Line CX drive with a new Mini Remote and integrated Bluetooth® System Controller Display into the top tube, as well as the AirWiz pressure monitoring.

• The new System Controller displays the currently selected support level and the remaining battery capacity. For maximum protection and an elegant look, it is beautifully integrated into the top tube.
• Bosch's new smart system offers the same power and responsiveness with a new, discreet Mini Remote that is elegantly reduced to the necessary controls to select support levels or activate walk assist.
• With TyreWiz and AirWiz, you keep an eye on the pressure in tires, fork, and shock – without a pump or gauge.
• The intelligent eMTB and eMTB Lite modes automatically adjust the support to your exerted power to give you just the right boost for your ride.
• The new frame is extremely stable – with a 34.9 mm seat tube to accommodate more robust dropper posts and an oversized head tube for sturdy forks optimized for e-MTBs.
