What kind of help do you need?

The SP5+ is designed for active riders who enjoy the feel of a lightweight fitness bike but want additional assistance for hills, longer distances, faster commutes, or arriving with less effort.

Its streamlined design and sporty riding position make it suitable for commuting, fitness riding, recreational trips, and mixed-surface exploration. It is a good option for riders who want electric assistance without the weight and utility-focused feel of a traditional e-bike.

The SP5+ has a maximum total load capacity of 265 lbs (120 kg). This includes the rider and everything carried on the bike, including clothing, water, accessories, racks, bags, and cargo.

A rear rack or other accessory may have its own lower load limit, which must also be followed. Exceeding the bike’s maximum capacity can affect handling, braking, and component durability.

Yes. The SP5+ supports full-length front and rear fenders. It is also compatible with universal rear racks that attach to the rear dropouts and seat stays.

The seat-stay bridge adapter must be installed underneath the seat stays when mounting the rear fender and rack. Compatibility can vary by product, tire size, and mounting hardware, so professional installation is recommended.

The SP5+ ships as a Class 2 e-bike, providing throttle and pedal assistance up to 20 mph.

Supported Class 3 settings may be available through the X‑LAB Bikes mobile app. E-bike classifications and permitted operating modes vary by location, trail, and roadway, so the rider is responsible for understanding and following all applicable laws.

Yes. The SP5+ battery uses Tier-1 cells sourced from LG, and the battery and complete electrical system are tested and certified to UL 2271 and UL 2849.

Use only the approved X‑LAB charger and follow all charging, handling, and storage instructions. Stop using the battery or charger if you notice damage, swelling, excessive heat, leakage, smoke, or an unusual odor, and contact an authorized X‑LAB dealer.

Most local bicycle shops can perform routine mechanical service, including brake adjustments, drivetrain maintenance, tire replacement, and wheel repairs.

For motor, battery, display, wiring, software, or other e-system work as well as warranty claims, we recommend visiting an authorized X‑LAB dealer. The electrical system and integrated battery should not be opened or serviced by the rider.

The SP5+ supports tires up to 45 mm wide, allowing riders to choose between faster pavement-focused tires and wider options that provide additional comfort and grip on mixed surfaces.

Actual tire width can vary depending on the tire model, rim width, tread pattern, and inflation pressure. Always confirm sufficient clearance around the frame, fork, brakes, and fenders after installing replacement tires.

The SP5+ uses a standard ISIS spline interface for its crank arms, making it compatible with a range of aftermarket crank-arm options.

Crank length affects pedaling mechanics, ground clearance, saddle height, and overall fit. Chainring compatibility also depends on the motor interface, chain line, drivetrain, and frame clearance. A qualified mechanic should verify all replacement components before installation.

The SP5+ motor and battery system are developed and manufactured in-house by X‑LAB. The battery uses cells sourced from LG.

Designing the motor, battery, controls, and software as a complete system allows the components to operate together as an integrated e-bike platform.

Yes. The throttle controller can be removed if you prefer a cleaner cockpit or do not want to use throttle assistance.

Because removal may involve electrical connections and system configuration, contact an authorized X‑LAB dealer. Do not cut, modify, or leave electrical connectors exposed.

The SP5+ battery is integrated into the frame and is not designed for routine removal by the rider.

When removal is required for service or replacement, it should be performed by an authorized X‑LAB mechanic. Riders should not attempt to open the frame or disconnect the battery themselves.
