Walmart offers the Stamina InStride 360 Degree Bike, model no. 15-0176, for $33.11. Opt for in-store pickup to avoid the $4.97 shipping fee. (Sears has it for the same price with free in-store pickup too.) That's $5 under our mention from two weeks ago and the lowest price we could find by $6. It features a steel frame, hook and loop straps, and adjustable straps.
