Done more shopping and have come across two great items from Lifeproof for the Brommie. Since I already have an iPhone, it would be logical then to use it as a GPS cyclometer. So how does one attach an iPhone to the handlebars of a Brompton, or any other bike for that matter? Finding an accessory that will attach on a Brommie handlebar that won't interfere when folding I'm finding a challenge. Lifeproof sells a watertight case:
and a bicycle mount that will work when folding down the bars. The nice thing is that the top part that the iPhone fits onto will pivot on a ball mount allowing it to to be moved to allow for folding. Here's the bike mount:
I just ordered these this morning. Will give the rundown when they arrive.
