• 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: All-New Series 4 Beyond Road E, 6061 Aluminum, One-Piece Hydroformed Downtube & Motor Mount, Internal Cable Routing, Mudguard and Rack Mounts, Flat Mount Disc, 142x12mm Thru-Axle · Fork: Marin Full Carbon w/ Tapered Steerer, 12mm Thru-Axle, Flat-Mount Disc, Fender Eyelets · Carbon Fiber

• 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 GRX STRX610, 12-speed · Rear derailleur: Shimano GRX RD-RX822, 12-speed, Clutch · Crankset: Forged Alloy, 42T Steel Chainring · Cassette: Shimano CSM6100, 10-51T · Chain: KMC E12S

• 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 GRX RX400, Flat-Mount Hydraulic Disc, 160mm Rotor / (R) Shimano GRX RX400, Flat-Mount Hydraulic Disc, 160mm Rotor; Levers: Shimano GRX STRX610

• 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: Marin Aluminum Double Wall, 25mm Inner, 18mm Tall, Disc Specific, Tubeless Compatible · Hubs: (F) Forged Aluminum Alloy, 100x12mm, Disc, 32H / (R) Forged Aluminum Alloy, 142x12mm, Disc, 32H · Front tire: Vee Tire Co., G-Sport, 700x44, Tubeless Compatible · Rear tire: Vee Tire Co., G-Sport, 700x44, Tubeless Compatible

• 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.
• Confirm whether the bike is actually set up tubeless, whether both tires hold pressure, and when sealant and rim tape were last serviced.

Archived: Headset: FSA No.42 ACB, Sealed Cartridge Bearings, 1 1/8” x 1 1/2” · Handlebar: Marin Butted Alloy, Compact 16º Flared Drop · Stem: Marin 3D Forged Alloy · Seatpost: Marin Alloy, 27.2 · Saddle: Marin Beyond Road Concept Elite · Pedals: Flats

• 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.

• 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.
