Carrying stuff around is a really popular hobby with some people, ranging from workmen to midwives, and especially those who have picnics or shopping expeditions to far off remote stores. So it makes sense that someone would design a bag/trolley combination which can convert into different tools for different tasks.

The Royal Shopper Plus is an ultra versatile carrier which has a capacity of 56 liters, and can transform from a standard rucksack to a crate carrier in a matter of seconds. There’s even a hook to let you attach it to a supermarket trolley for ultimate flexibility.

If you use one of the optional hitches, you can connect the trolley and bag to the back of a bicycle as a trailer, which instantly expands your carrying options and range, and the thing is designed to support up to 50kg in weight, so it’s good for a fair amount of stuff. It’s water resistant, has an insulated compartment and features reflectors for more visibility. Priced at £159.95.
