Hey andrew found some solutions for you. Should be a go'er. Look this one even turns heads its so trendy
It can take uber dual pie speeds too:
And one for that Mrs. of yours
wink
These are an option, I think they are pretty radical
And a home made version! hehe
My great grandfather had a similar problem actually, so he fitted a telescope to his balloocycle. I scraped around and found this old pic of him
And I found this picture of when I was a kid (and yes I've since changed the wheel color!!! it was a phase I was going through back then....)
I would probably go the nubrella way, as the telescope could poke an eye if you had to brake quickly
But on a serious note, could you wear a full face helmet in wet weather conditions? You can get some BMX/downhill styles with visors that could be an option...
Peace out
MM
