The frame is UDH compatible. Listed interfaces include a 110 × 15mm front thru-axle and a 31.6mm seatpost. The drivetrain uses Shimano CUES 9-speed gearing, an 11–46T cassette and a 46T narrow-wide chainring.
Use manufacturer-approved battery, charger and electrical replacement parts for the XDS X800 system. Confirm rear axle dimensions, rim specifications, maximum tire clearance and tubeless approval with Go Grava before changing wheels or tires.
Check rack accessory compatibility and load limits before fitting cargo or a child seat. Quad Lock phones require the appropriate compatible case or adapter. Apple Find My setup requires a compatible Apple device and account.
In-store pickup only at Go Grava. This e-bike is not available for shipping. Confirm availability and arrange professional assembly and pickup with the shop.
Built for everyday commuting, errands and comfortable city riding, with a low step-through frame for easier mounting. Medium and Large fit differently in reach as well as rider-height range; a professional fit is the best way to confirm control and comfort.
Professional dealer assembly and setup are required. Maintain the drivetrain, brakes, tires and electrical system according to the manufacturer's instructions, and confirm the actual production build before ordering service parts.
The integrated display and front light, MIK-HD rack, fenders and Quad Lock mount support daily use. Find My is a location-assistance feature; continue to use a suitable physical lock.
Manufacturer rider-height ranges are starting points, not a fit guarantee. Try both sizes if you are between sizes, and confirm reach, saddle position and mounting comfort with Go Grava. The LS frame has a listed 445mm stand-over height in both sizes.

| M | 157.0–173.0 | 667.0 | 400.0 |
