Im considering a 2 wheeled bent , just need to try one out, no idea how to though .
It might solve my dodgy nerve /neck / hand tingly issues i though if i was just holding the bars ?
I switched to a bent for similar reasons. IMO a learning to ride a recumbent bike is like re-learning to ride. Awkward at first, but not hard, and once mastered riding a recumbent is as easy as any bike, but much more fun.
From a neck fatigue perspective one of the important differences between a recumbent and an upright is that you aren't holding your head up, but rather balancing it on you shoulders. It's a far more relaxing position that allows you to look around, ahead and up with no effort. With an upright the head drops down after an hour or so, your neck begins to ache, and and you don't see much further than the first few yards ahead of your front wheel.
BTW, The difficulty of riding a recumbent bike to the uninitiated has a hidden advantage so don't let it put you off. Your bike doesn't suffer from the same risk of theft as an upright. Opportunistic theft depends on the thief being able to cycle the goods away. Wheeling a recumbent away isn't the best option for a bike that attracts attention wherever it goes.
