This Huffy 10" Disney Frozen Bike or Huffy 10" Marvel Spider-Man Bike each drop from $34.97 to $19 at Walmart.com. This is lowest price we've seen on either one all year. There's no coaster brake (the bike stop when you stop pedaling, like a tricycle) and it has training wheels and a padded front handlebar. Spend $50 for free shipping, otherwise it adds $4.95 (you can also order for free store pickup). Sales tax is charged in most states.
