Ken Rogers Trike

That looks like a nicely updated machine that should be reliable in use.

Some hints that you probably already know.

Keep your feet on the pedals (clipless ideally) unless you are stationary. You don’t want your foot catching on the ground while the rear axle is moving forwards.

The steering and the lean of the trike (e.g. camber) are completely independent, unlike a bicycle where turning and leaning are intimately connected. Some folk take a while to learn new habits/ techniques. I was one that initially needed quite a bit of concentration just to ride it, before becoming comfortable in traffic and potholes. Find a flattish area with nothing to run into and practice riding straight lines and gentle cornering before you take it out on the road.

Put all your weight on the inside pedal when cornering and position your shoulders well to the inside and low. Undemanding turns can be done with your bum on the saddle (perhaps pedalling) but adverse camber and fast turns may need you to get your bum just about sitting on the inside rear wheel too. That sort of thing is a lot of the fun of riding an upright trike and why I much prefer racing at Gravesend to Betteshanger.

Let me know if you want some help with specific riding issues.
