Grannies rev their wheelchairs

The next time somebody pulls up beside your ride and tells you that their grandma can leave you biting dust, they are probably not joking. This miniature grandma who is wheelchair bound is actually a speed devil in disguise. When you have properly set up the racing track, all you need to do is pit both grannies together and watch them slug it out grandma-to-grandma. The outcome of the race is unpredictable as it depends on the skill of the controller. These grannies do not feed on hot chocolate and marshmellows but a quartet of AA batteries instead. You can purchase the entire Racing Grannies set for approximately $20.
