How do you know you want a bigger front wheel if you don't HAVE a BikeE???
I had a similar notion when I got my first recumbent (Challenge Hurricane). I rode it about 150 feet and crashed. I was sure that the forks needed some more rake,.. or SOMEthing!
After looking it over more carefully (I got it used, sight unseen) I realized that the bike was very well designed and built, SOOooo, the problem was most likely ... wait for it ...
I have since mastered the twitchy little racer and can now do powerslides on it.
You either need to modify (big PITA with unknown results) or select a different recumbent. There are lots of styles out there with bigger than 16" front wheels. But most are significantly more $ than a BikeE.
If you do get a BikeE and modify it, I'd be interested in hearing how it works for you.
