Trek hybrid-style bicycle, with the larger 29-inch/622mm/700C wheels, mounted to a steel stepthrough frame with vertical dropouts etc. Adjustable stem, riser bars, Sram gripshifts, v-brakes. Three chainrings with a derailleur up front and seven sprockets in rear, for various gearing combinations with a pretty solid chain. Might need new tyres; I think the sidewalls are a bit rough. The saddle isn't original, but it still should serve unless you want something fancier (and/or matchy matchy with Trek branding).
