It breaks down pretty easy - guy wants bike.
There are always two camps on this - 1: start small and cheap, and buy big bike later. 2: start big.
Instead Ilya decides that he will keep small bike, and buys it new. Then rides a big bike and realizes small bike isn’t fun as indefinite keep and only option.
So he spent money buying a learning bike new instead of used, and now wants a big bike in the future anyway.
