A bicycle postal delivery service based in Bristol is to trial its first post box in the city.
Velopost is installing a public post box in the city's tourism office on the waterfront, on 29 May.
Using the firm's own postage stamps, customers will be able to use it to send mail to addresses in the city.
Jo Broadway, from Velopost, said: "We're planning to roll it out, with roughly a network of 25 post boxes across Bristol."
Set up four years ago, the cycle delivery service currently delivers around a million letters a year within Bristol, Bath and Edinburgh.
But up until now, its lycra-clad cyclists have only been collecting post from business premises in the city.
"There's a small amount of residential mail going already but it's mostly just businesses," said Mr Broadway.
"But by providing an alternative post-box we're now able to expand our cycle delivery service to everybody in Bristol."
