There is another version that includes bus travel as well but costs more and doesn't have a child discounted version (so you would pay the hugely expensive price of £6.20
).
That's because, unless you look
under 11 years old, bus drivers won't let you on a bus with a child ticket without ID in West Yorkshire.
In York, it is up to 13 years old, they are very strict but can't accurately guess people's ages so they reject 12 year olds without ID and accept 16 year olds without ID if they look older/younger than their age, I'm informed. (e.g. 2 twins both aged 16, one gets away with it, the other doesn't, though they are brothers they don't look like twins).
I got a bus on my own when I was 12 and then didn't again until I was about 19 because I had no reason to get on their rubbish buses, being slower and more expensive than going by bike. And if I was going somewhere long distance by train with family I'd have been in a car/taxi, a taxi is cheaper than the bus for a family of 4 in York. Therefore, I didn't really experience for myself how strict they are, but I heard.
Despite this, the buses are well loaded, this is due to a huge number of people who are eligible for free passes, and the unfortunate decline in people using the faster, cheaper mode of transport that is cycling.
