Northrock fat bike. A really fun ride and an excellent climber, but it's surplus to my needs now. It's in great shape mechanically, but I've offroaded it a fair bit, so the frame has some nicks and scratches. Lots of tread left on the tires. Deore components make this much smoother and more reliable to shift than other bikes at this price point (i.e. fat bikes found at Walmart and Canadian Tire). The specs say medium sized frame. I am 5'9" and it fits me perfectly, with the seat as shown in the picture. Likely better for 5'10" and shorter depending on your riding style. https://www.costco.ca/northrock-xcf-66-cm-(26-in.)-fat-tire-bike.product.100785971.html
