This logo is going to form the brand for the app/business so it needs to be good! It will be used within the app itself, as part of the splash screen when the app loads up and also on the accompanying website to promote the app.
In terms of the logo, we're open to suggestions of the style and design. Would like to create a character of sorts to be used to bring the app to life, maybe a cartoon character style guy riding a bike, or a bike image, or a cool dude in a biker jacket - Like we said, open to suggestions so let your creativity shine!
The name of the app 'Sell A Bike' needs to be included (not case sensitive so either SellABike or Sell a Bike, or whatever, is fine). The only important stuff to think about is that there needs to be some strong reference to motorbikes - a bike, helmet, rider - something. We'll be providing feedback to designs early on.
