• 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: A1 Premium Butted Alloy, unisex frame, internal cable routing, 110x10mm dropouts · Fork: A1 Premium Butted Alloy, Alloy steerer, V-Brake · Aluminum

• 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: Crankset: Forged Alloy, Square Taper, Single Speed, w/ Chainguard; chainrings: 34T · Bottom bracket: Square taper, Plastic cups, 113mm spindle · Cassette: 18t Freewheel · Chain: KMC Z1 EPT (Anti-Rust)

• Check chain tension and chainline, rotate the drivetrain through a full revolution and confirm the rear axle or tensioning hardware cannot slip.
• 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: (F) V-brake w/ tool-less reach adjust brake lever / (R) V-brake w/ tool-less reach adjust brake lever

• Inspect pads, cables and housings, then examine both rim braking surfaces for concavity, cracking or heavy wear. Confirm each caliper returns and centers correctly.
• 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: Rims: Alloy, 14mm Depth, 23mm Internal Width, 28H · Hubs: (F) Alloy, Loose Ball Bearings, Bolt type, 100mm Spacing, 28H / (R) Alloy, Loose Ball Bearings, Bolt type, 110mm Spacing, 28H · Front tire: Pathfinder Sport, 20x2.0" · Rear tire: Pathfinder Sport, 20x2.0"

• 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: Alloy Mini Rise, Double Butted, 60mm Rise, 5-degree Backsweep, 580mm Width, 25.4mm Clamp Diameter, 19mm Bar End Diameter · Stem: 3D Forged Aluminum, 35mm length, 6 degree rise, 25.4mm clamp diameter · Seatpost: Alloy, 2-bolt, 14mm offset, 27.2mm · Saddle: Kids Bridge Saddle, 130mm · Pedals: Nylon platform w/ reflectors

• 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.

• 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.
