I ride with Magped and they work like a charm. I started with the Magped Sport towards the end of last year and later upgraded to the Magped Enduro. Its a lot of money to pay for pedals but its been worth it for me. I'm terrified of clipless since I fell and broke a few ribs coz I couldn't clip out on time. "Unclipping" on the Magped is exactly the same as you'd do with flats, you simply lift your foot off the pedals but you also attached to the pedals when climbing/pedaling or going downhill. I was used to pulling on the pedals when climbing so flats didn't quite do it for me. I've listed my old Magped Sport for R1500.00 on the classifieds.
Great trails, and they host good triathlon events, both MTB and road. Rode once last year for a MTB triathlon. They have launched a Mountain Bike Series with 8 races planned for this year. First race is on the 7th of March, think I'll start
