Product Details
The XDS X-LAB ST5+ LS brings serious mid-drive engineering to everyday city riding, built for commuters who want to trade car trips for something faster, cleaner, and a lot more enjoyable. Built on a refined aluminum platform, it pairs smooth, torquey acceleration with confident handling and genuine all-day comfort, whether you are heading to work, running errands, or taking the long way home just because you can.
At the heart of the ST5+ LS is a mid-drive motor engineered in-house by X-LAB as part of a complete platform, not just bolted on as an afterthought. It delivers torque where riders actually need it, smarter control through the integrated Branta ecosystem, and a ride feel that stays composed on hills, from a stop, and while hauling cargo. A substantial 619Wh battery backs it up with a range of up to 75-plus miles, giving riders the confidence to take the long route without worrying about the charge level.
The cockpit is where the ST5+ LS really shows its tech-forward approach. A fully integrated dashboard puts speed, range, and assistance settings right in view, and the bike pairs with the X-LAB Bikes app for ride customization, diagnostics, and over-the-air updates, so the bike keeps improving long after it leaves the shop. Apple Find My integration adds a real layer of anti-theft protection that most commuter bikes simply do not offer.
Weighing in at around 54 pounds, the durable alloy frame is built to handle the real demands of city life, from daily commutes to grocery runs, with a total weight capacity of 330 pounds covering rider, cargo, and accessories. The low-step frame design makes mounting and dismounting easy in stop-and-go traffic, and the comfort-focused setup, with 2.4 inch tires and an 80mm suspension fork, smooths out rough pavement and uneven bike paths alike. A Class 2 throttle offers pedal and throttle assistance up to 20 mph, and a Shimano CUES 9-speed drivetrain provides smooth, dependable shifting for everything the city throws at it. An MIK rear rack adds practical cargo capacity for groceries, work essentials, or whatever the day requires.
