The Spawn Cycles Yama Jama 20” raises the bar for kids' bikes and is the ultimate 20" trail bike for kids age 4-7 years.
It all starts with a 6061-T6 alloy frame using hydroformed and double-butted tubing, a semi-integrated head tube, a unique forged BB shell/yoke for added stiffness, ISCG-05 tabs and even an internal routing option for dropper posts. The Brood Bike Co. Eldorado fork features a hand-laid carbon fibre lower, a replaceable cartridge damper with a rubber bladder, lockout, a 15mm through-axle and 80mm of plush, nearly stiction-free travel.
The drivetrain starts with the Brood Bike Co. Styx 130mm crank using a SRAM type direct mount interface for the chainwheel and a sealed external bottom bracket. We add a brood bike co. 30T narrow-wide alloy chainwheel and then utilize a SRAM GX derailleur and shifter combo to get things moving to the 11-36T 10 speed SRAM cassette. Stopping is handled by powerful Tektro AURIGA hydraulic discs. The next big highlight is the wheelset and tires.
The Yama Jama uses Brood Bike co. tubeless-ready rims with a wide profile and tops it off with the amazing Brood Bike Co. Maxtion foldable, tubeless-ready tire. Touchpoints matter for kids too, so we’ve topped this Yama Jama off with Brood Bike Co.Tenderiderz lock-ons and the Brood Throne seat with a unique Pivotal mechanism that provides fore/aft adjustment.
