Product Details

The X-LAB SP5+ is a lightweight fitness-focused electric bike designed to make everyday riding faster, smoother, and more enjoyable without losing the natural feel of a traditional bicycle. Built around a sleek alloy frame, responsive mid-drive motor system, and modern smart technology integration, the SP5+ blends performance, comfort, and practicality into an approachable all-around e-bike platform.

Weighing in at approximately 37 pounds, the SP5+ stands apart from heavier commuter-focused e-bikes by delivering a more agile and responsive ride quality. Its balanced geometry and fitness-oriented riding position create a sporty yet comfortable feel that works equally well for commuting, fitness rides, neighborhood cruising, and longer weekend adventures. Paired with fast-rolling 700c wheels and versatile gravel-inspired all-terrain tires, the bike maintains confident handling across pavement, bike paths, and light mixed-surface routes.

At the center of the SP5+ is a powerful mid-drive motor system capable of delivering up to 85Nm of torque for smooth acceleration and intuitive pedal assistance. The Class 2 throttle system adds extra versatility for stop-and-go city riding or quick acceleration when needed, while the refined motor integration keeps the overall ride feeling natural and efficient.

The Shimano CUES 9-speed drivetrain provides dependable shifting performance with gear range suitable for urban riding, rolling terrain, and fitness-focused mileage. Integrated front and rear lighting improves visibility for early morning commutes and evening rides, while the rear taillight features built-in brake light functionality for additional safety in traffic.

Modern connectivity features elevate the SP5+ beyond a traditional electric bike. Apple Find My compatibility adds an additional layer of anti-theft security and bike tracking, while integrated app functionality allows riders to manage ride settings, updates, and system personalization directly from their smartphone.

Cleanly integrated, lightweight, and purpose-built for everyday riding, the X-LAB SP5+ delivers a refined electric cycling experience for riders who want efficiency, versatility, and smart technology in one sleek package.
