• 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.

• 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 Deore, RapidFire Plus, 10-speed w/ Optical Gear Display · Rear derailleur: Shimano Deore, Shadow Plus, GS cage, 10-speed · Crankset: Custom alloy forged crankarms; chainrings: Praxis, 48T, 104BCD · Cassette: Shimano Deore, 10spd, 11-42t · Chain: KMC X10eT, 10-speed w/ Missing Link™

• 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: (F) Shimano BR-MT200, hydraulic disc, 180mm / (R) Shimano BR-MT200, hydraulic disc, 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: Rims: 650b disc, double-wall alloy, pinned, 32h · Hubs: (F) Specialized front hub disc, sealed bearings, 15x100mm thru-axle, 32h / (R) Specialized, sealed cartridge bearings, 12x148mm thru-axle, 32h · Front tire: Nimbus II Sport Reflect, 60 TPI, 650b x 2.3" · Rear tire: Nimbus II Sport Reflect, 60 TPI, 650b x 2.3"

• 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: Specialized, alloy, 30-degree backsweep, 26mm rise, 680mm width, 31.8mm · Stem: Specialized Flowset, 3D-forged alloy, 20-degree rise, 31.8mm clamp · Seatpost: Specialized, alloy, 2-bolt, 12.5mm offset, 30.9mm · Saddle: Body Geometry "The Cup," 6-degree rise, elastomer base, steel rails, SWAT™ compatible mounts, 245mm · Pedals: Specialized Commuter w/ grip tape & 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.

Archived: Motor: Specialized 1.2, custom Rx Street-tuned motor, 250W nominal · Battery: Specialized U1-500, On/Off button, state of charge display, 500Wh · Display: Specialized TCD-W w/ handlebar remote & built-in anti-theft feature, Bluetooth® connectivity, 5 available display pages · Charger: Custom charger, 42V4A w/ Rosenberger plug, 100-240V

• 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.
