It\'s designed around a Gates belt drive and Shimano\'s 8-speed internal-gear Alfine hub. The result is a practically silent super-commuter with no greasy parts or protruding derailleurs, plus a gear range for any incline. The S8i has an extra-long wheelbase and Schwalbe Big Apple tires, so it rolls confidently over any and all potholes. It will get you there quickly, cleanly and most importantly, in style.Revolutionary Gates Carbon Drive drivetrain for a quiet, light and clean bikeShimano Deore hydraulic disc brakes for extreme stopping powerAndros handlebar stem for tool-free riding position adjustments on the flyBright, wide-beam Valo Light powered by the BioLogic Joule 3 electricity-generating hubSchwalbe Big Apple tires with Kevlar puncture protectionFolds in under 10 seconds to fit under a deskFenders for rainy daysCargo Rack for hauling up to 25 kg (55 lb)Size: 20”Speed: 8 SpeedMax weight: 120kb (264lb)Frame: Tern Verge, hydroformed aluminium w/smooth TIG welding, OCL+ joint, 3 patented technologies Fork: Tarsus, 6061-AL, hydroformedStem: Tern Andros, adjustable, forged construction, patented technologyHeadset: Flux Pro, angular contact bearings, Physis integratedHandlebars: Kinetix Comp, double-butted 6061-AlBar Tape/Grips: Phorm, w/bar endSaddle: Tern Porter+, patented GripPad design, PrimeGel paddingSeat Post: Stasis by Syntace, 7050-Al, hard-anodizedSeat Clamp: Syntance OverLookSpokes: Stainless, double-buttedRims: Kinetix Comp, doublewallTyres: Schwalbe Big Apple 55-406, puncture protection, Reflex Shifters: Shimano Alfine, 1 x 8 spdCrankset: Gates Carbon DriveCassette/Freewheel: Gates CDX, precision CNC machined cogBottom Bracket: Cartridge, sealed bearingsChain: Gates Carbon Drive beltPedals: MKS UB-LITE EZY, QRBell Type: Pitch, brassKickstand: Rear mount, Pletscher designFront Light: Tern Valo 2, integrated, 41 lux/150 lumensRear Light: Spanninga Pixeo XDSColour: Metallic Grey
