With 170mm travel front and rear, the Bullit draws heavily from downhill bike design. The FOX 38 Float Performance Elite fork provides stiffness and control when charging into chunky terrain, while the Float X Performance Elite rear shock delivers a balanced, supportive feel through big hits and repeated impacts. This suspension package allows the bike to maintain composure on demanding trails while remaining agile enough for technical features and tight switchbacks.
SRAM’s GX Eagle AXS T-Type drivetrain brings wireless 12-speed shifting with impressive durability and smooth engagement, designed to handle the torque loads of e-MTB use. Powerful braking comes from SRAM Maven Bronze callipers, paired with large rotors for dependable modulation and control when gradients steepen. Reserve 30|HD alloy wheels add strength and reliability, wrapped in Maxxis Assegai and Minion DHR II DoubleDown tyres for serious grip and puncture protection.
Bosch’s Performance Line CX motor supplies up to 85Nm of torque, making climbs more manageable and helping you preserve energy for the ride down. Paired with the 600Wh PowerTube battery, the system provides a balance of power and range ideal for longer or steeper mountain routes. The Bosch display and remote offer intuitive control, keeping your cockpit clean and functional.
Whether you're tackling lift-accessed descents or exploring rugged mountain terrain under your own power, the Bullit 4 combines downhill confidence with e-bike uplift when you need it most, making every trail feel within reach.

* Mountain bikes are sized differently to road bikes. Typically, they are sized in inches as the first MTBs were produced in the USA. European brands like Lapierre and Haibike like to use centimeters for all their bikes. The measurements of their mountain bikes doesn’t match their road bikes but is like a simple conversion from the inches measurement. This is why we have included cm measurements in brackets for the e mountain bike column.
