You can still write SQL queries directly using Model.query(). Since this is an asynchronous function, you'll have to use promises or async to reserialize it. For instance, using the MySQL adapter, async, and a model called User:

async.auto({
  transaction: function(next){
    User.query('BEGIN', next);
  },
  user: ['transaction', function(next) {
    User.findOne(req.param('id')).exec(next);
  }],
  // other queries in the transaction
  // ...
}, function(err, results) {
  if (err) {
    User.query('ROLLBACK', next);
    return next(err);
  }
  User.query('COMMIT', next);
  // final tasks
  res.json(results.serialize);
});
