It'd be extremely helpful to put the size .... get the model number right and a model year. Plus the spec (for the correct bike), a bit of maintenance history etc
Just saying what wheels they are (which are the only thing visible from the pics but none of the rest of the spec ), won't sell the bike (at anywhere near £450). You'll need to make a lot more effort to sell, load of pictures and details. If I were looking for a bike like that, I'd skip straight over your ad as you're expecting a buyer to do all the research, send you messages to get answers to basic questions! It's a competitive market, make it easy for the buyer!
Also specify that you have a receipt for the bike

(if you don't, you'll limit your market and sale price). If I were to read that ad, I'd think the seller has no idea what it is and thus I'd think it was being sold by a thief who'd stolen it. Make it sound like you know and love the bike
