• Confirm the frame markings and seller description match this archived model. Note every component that differs from the published build.
• Record the frame serial number. It should be legible, unaltered and consistent with the seller’s ownership history.
• Find the size marking on the bicycle and confirm the fit before judging the condition or price.

Archived: Frame: XDS X6 Alloy Frame, UDH Compatible · Fork: XDS Carbon Fork, 100x12mm Thru-axle · Carbon

• Look for dents or shape changes and inspect the edges of welds around the head tube, bottom bracket, seat cluster and suspension mounts for hairline cracks.
• Stand behind and in front of the bicycle to look for obvious frame, fork or wheel misalignment. Ask directly about crashes, transport damage and repairs.
• Inspect the fork crown, blades, dropouts and visible steerer area. Check that it is straight, securely installed and free of cracks or impact damage.

Archived: Shifters: Shimano Cues 9-Speed · Rear derailleur: Shimano Cues RD-U4000, 9-Speed · Crankset: Branta Alloy Crankset, 46T, Narrow-wide Teeth · Cassette: Shimano CS-LG300 11-46T, 9-Speed · Chain: KMC E-GLIDE-S

• Shift through every available gear under light load. Hesitation, skipping or inconsistent indexing can reflect wear, damage, poor adjustment or mismatched replacement parts.
• Measure chain wear with a compatible gauge and inspect chainring, cassette or freewheel teeth. A new chain does not rule out wear in the remaining drivetrain.
• Turn the cranks slowly, feel for rough bearings and check for side-to-side play. Inspect crank arms, chainring bolts and pedal threads for looseness or damage.

Archived: Brakes: Branta EC215D Hydraulic E-Bike Brake, w/ Cutoff Switch, 3 Finger Lever; 2 Piston Caliper; Rotors: Branta Z8, F:160mm R:160mm

• Squeeze each lever firmly. It should feel consistent and return cleanly. Check levers, hoses and calipers for fluid, inspect pad thickness and contamination, and examine rotors for wear or bending.
• Before riding, test every installed brake separately at walking speed. Each should stop firmly and release cleanly without its control reaching the end of its usable travel.

Archived: Wheel size: 700C · Wheels: Branta Alloy E-Bike Wheelset · Front tire: Branta R240, 700x40C, 30TPI; Max Tire Clearance: 45C w/ Full-Wrapped Fender · Rear tire: Branta R240, 700x40C, 30TPI; Max Tire Clearance: 45C w/ Full-Wrapped Fender

• Spin both wheels and watch for side-to-side and vertical movement. Check spoke tension, rim condition and hub play.
• Inspect both tire casings for cuts, cracking, plugs, bulges or exposed threads and confirm the installed sizes are safe for the rims and available frame and fork clearance.
• Remove and reinstall or closely inspect both wheel-retention systems. Axles or quick releases should tighten correctly with undamaged threads, hardware and dropouts.

Archived: Handlebar: Branta Alloy Integrated, w/ Display & Front Light, 680mm; Width, 90mm Length, 6 Degree Rise, 9 Degree Backsweep · Stem: Branta Alloy Integrated, w/ Display & Front Light, 680mm; Width, 90mm Length, 6 Degree Rise, 9 Degree Backsweep · Seatpost: XDS Alloy Seatpost, Aero Shape, 350mm Length · Saddle: Branta SRX+

• Apply the front brake and rock the bike to check for headset play or notchiness. Inspect the stem, handlebar and clamp zones, then confirm every fastener and control is secure.
• Check that the seatpost moves for adjustment and that the saddle, post and clamp hold securely without cracks, severe corrosion or damaged hardware.

Archived: Motor: XDS Mid-drive X800 Motor, 250 Watt Continuous Rated Power, 400 Watt Peak Power, 85Nm Peak Torque, Dual-sided Torque Sensor · Battery: XDS Rechargeable Li-ion Battery, 339Wh, LG Battery Cells, 3A Charger (0-100% 3hr 15min)

• Inspect the battery case, mount, lock and electrical contacts for cracks, impact, corrosion, swelling, overheating marks or looseness. Confirm the battery charges normally.
• Confirm the correct charger, battery keys and removable system parts are included. Check charger cables and connectors for damage or improvised repairs.
• Power the system on from cold, check the display for warnings, and test every assist mode. Assistance should engage and stop predictably without intermittent cutouts or abnormal motor noise.
• Ask for available battery-health, cycle-count, diagnostic and firmware records. Confirm that replacement batteries and system support remain available before agreeing on value.

• Before riding, confirm both wheels are secure, tires are safe, both brakes function, and the headset, handlebar, stem, cranks and pedals have no looseness.
• Begin at low speed. Test steering, braking and shifting progressively, then load the drivetrain and suspension only after the basic safety checks pass.
• Listen and feel for repeated knocks, grinding, skipping, brake pulsation or movement at joints. Stop the test if the bicycle cannot be controlled safely.
