X-LAB SP5+ Electric Fitness Bike | Mid-Drive | Shimano CUES | 700c
X-LAB SP5+ Electric Fitness Bike
A lightweight electric fitness bike that rides like a traditional bicycle—with an 85Nm mid-drive motor ready to give you an extra push whenever you want it.
The X-LAB SP5+ is built for riders who want the convenience of an e-bike without the weight, bulk, and disconnected ride feel of many traditional electric bicycles. At approximately 37 lbs, the SP5+ is remarkably light for a mid-drive e-bike, making it easier to maneuver, transport, store, and pedal even when the motor is turned off.
At the heart of the bike is the XDS X800 mid-drive motor, producing 250 watts of continuous power, up to 400 watts of peak power, and an impressive 85Nm of peak torque. A dual-sided torque sensor measures rider input and delivers assistance naturally, creating a smooth ride that feels more like amplified pedaling than a traditional hub-motor e-bike.
The integrated 339Wh lithium-ion battery uses LG battery cells and provides up to 43 miles of riding range on a single charge. A 3A charger can recharge the battery from 0–100% in approximately 3 hours and 15 minutes.
The SP5+ is configured as a Class 2 e-bike with both pedal assist and throttle operation up to 20 mph. Riders can also unlock Class 3 operation through the X-LAB Bikes mobile app where permitted by local regulations.
A Shimano CUES 9-speed drivetrain with an 11-46T cassette provides a wide mechanical gear range for hills, commuting, fitness rides, and mixed terrain. The 46T narrow-wide chainring helps keep the drivetrain simple and secure while maintaining efficient road speed.
Branta hydraulic e-bike brakes feature integrated motor cutoff switches, while 160mm front and rear rotors provide controlled braking performance. Integrated front and rear lighting—including a rear brake light—adds visibility for commuting and everyday riding.
Modern connectivity is built directly into the platform with Apple Find My anti-theft technology, Bluetooth connectivity, over-the-air firmware updates, app-based controls, and ride tracking.

Who Is the SP5+ For?
The SP5+ is particularly well suited to commuters, fitness riders, recreational cyclists, and riders who want electric assistance without giving up the handling and pedaling characteristics of a traditional bicycle. Its lightweight chassis also makes it a strong option for riders who need to carry an e-bike up stairs, load it onto a vehicle, or regularly move it in and out of storage.
Before You Buy
- This bicycle ships as a professionally assembled and serviced electric bicycle through authorized X-LAB dealers.
- Maximum assisted speed and throttle regulations vary by state and municipality.
- Class 3 functionality should only be enabled where legally permitted.

The X-LAB SP5+ stands out because it doesn't try to make an e-bike feel like a motorcycle. Instead, it starts with a lightweight fitness-bike platform and adds a powerful, quiet mid-drive system, intelligent connectivity, and practical commuting features. For riders who still want to pedal, exercise, and enjoy the feel of a bicycle—but want assistance when the road gets longer or steeper—the SP5+ is an exceptionally compelling platform.
