• 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: SmartForm C3 Alloy step-thru frame, removable downtube battery, fully internal cable routing, post mount disc, dual water bottle headtube mount · Fork: SmartForm C3 Alloy blades, 1-1/8" steerer, post mount disc, mid-blade rack/fender mounts, crown accessory mount, 45mm offset · 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: Shifters: microSHIFT Marvo XPress M859, trigger style, 9-speed · Rear derailleur: microSHIFT Marvo, 9-speed · Crankset: FSA Bosch E-Bike, 38T · Rear cogs: microSHIFT, 11-36, 9-speed · Chain: KMC Z9, 9-speed

• 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: Brakes Tektro M275 hydraulic disc, 180/160mm rotors Brake Levers Tektro hydraulic disc

• 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: 650b · Rims: Cannondale 2, double wall · Hubs: (F) Formula DC-1420, QR / (R) Formula DC-1422, QR · Front tire: Kenda Kwick Seven.5, 27.5x2.20" · Rear tire: Kenda Kwick Seven.5, 27.5x2.20"

• 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: Headset: Semi-Integrated, 1-1/8" · Handlebar: Cannondale Low-Rise Urban, butted 6061 Alloy, 31.8mm, 25mm rise, 35° sweep, 680mm · Stem: Cannondale 3 with Intellimount, Alloy, 31.8mm clamp · Seatpost: Cannondale 4, 6061 Alloy, 31.6x350mm · Saddle: Cannondale Ergo Comfort

• 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.
