No longer needed, in excellent condition. Has been hung up in our garage for some time now. This pedal trailer / trailercycle / trail-a-bike really helps teach kids how to ride on their own. I strongly recommend it! Brand: Trek Model: Dialed Fit Specific Design Wheel size: 20 inches (Older model, a TREK classic)! You will need to order an attachment as ours has been misplaced (lost). Though you must order it specifically at any Trek bike dealer. (Trek bike dealers: Elevation Cycles, Campus Cycles, Bicycle Village, Peak Cycles, Trek Bicycle Boulder, and more in other cities in Colorado). These retail between $299.99 and $399.99 Selling for only $100 (cash only please)! FREE with purchase: kid's bike helmet and Schwinn elbow and knee pads set (see picture)! (I'm located near I-25 and I-70 in Denver (Coliseum area); or at Alameda and Federal certain days of the week. Occasionally I drive to surrounding areas such as Littleton, Englewood, Lakewood, Aurora, Arvada, Broomfield, Centennial, Highlands Ranch, etc.) Thank you for looking! Hablo español!
