A pony this size needs a small rider. A weight of 50 to 80 lbs would be ideal. Depending on the build and health of the pony may also factor into his weight limit. Remember too, if a child starts to outgrow his pony he can always be trained to pull a cart. A 12hh pony can easily pull a cart and full grown person. Warning:If your pony has never been trained to drive don't try to do this yourself. This can be dangerous if you don't know how to train.
There is no such thing as a 'miniature Shetland' pony. You have either a Miniature horse or a Shetland pony. Mini's should never be ridden by anyone ever, they have fragile spines that can be hurt by direct weight. They can however pull a small pony cart with one or two adults in it. Shetlands are a breed of small pony that are very strong and make a great first pony for a kid. They can also pull a cart if trained correctly.

Any equine, including donkeys and mules, can pull their own weight (cart n harness animals) and carry 20% of their own body weight. So if your mini is 300 lbs he can 60lbs (that includes tack as well). Donkeys are reputed to being a bit stronger than horses, but the standard rule of thumb is they can pull how much they weight and they can ride 20% of what they weigh.
how much you weigh depends on the pull gravity has on you.
