XDS X-LAB ST5+

The X-LAB ST5+ is a modern urban e-bike built for riders who want more from their daily commute. Constructed on an XDS X6 alloy frame with UDH compatibility, the ST5+ pairs a refined platform with an upright yet sporty geometry that works equally well for new riders and experienced cyclists. An XDS suspension fork with 80mm of coil spring travel and 15mm thru-axle takes the edge off rough pavement and imperfect urban surfaces, keeping the ride comfortable from the first block to the last.

At the heart of the ST5+ is the X-LAB X800 mid-drive motor, developed and manufactured in-house, delivering 250 watts of continuous rated power, 470 watts peak, and 95Nm of peak torque via a dual-sided torque sensor for natural, responsive assist. The integrated 619Wh LG cell battery supports a range of up to 75 miles on a single charge and reaches full charge in approximately five hours. The ST5+ operates as a Class 2 e-bike out of the box with both pedal-assist and throttle up to 20mph, and can be unlocked to Class 3 via the X-LAB Bikes mobile app. The battery is UL2271 and UL2849 certified, rated IPX7, with the complete bike carrying an IP54 ingress rating.

Shimano Cues handles shifting duties with a 9-speed RD-U4000 rear derailleur and matching shifter paired to an 11-46T cassette, giving riders a solid range for navigating hills and flats. Branta EC4D four-piston hydraulic disc brakes with e-bike cutoff switches provide confident, controlled stopping power, and 180mm rotors front and rear keep braking performance consistent under load. The integrated cockpit combines the handlebar, stem, display, and front light into a single clean unit, and is cross-compatible with other X-LAB e-bike cockpits.
