The path on which I’m riding my e-mountain bike across the hills of north Pembrokeshire is known as a bridleway, but to Ed Sykes, who grew up in these hills, it’s an “e-trail”. Ed is the founder of Hidden Routes in Newport (between Cardigan and Fishguard), an e-mountain biking outfit that takes clients on guided rides through what is probably the least-known corner of Pembrokeshire.
