Rail 9.9 X0 AXS T-Type Gen 4

The Rail 9.9 is our best long-travel electric mountain bike. You get an extra-beefy carbon frame, an unbelievably smooth RockShox suspension, SRAM’s best wireless electronic drivetrain and a powerful Bosch smart system Performance Line CX motor with an extra-long range battery and the new Mini Remote. The new System Controller display sits almost flush with the top tube for a sleek look wherever you roll that stays out of the way when you’re riding hard.
