I've got a Nihola trike, the thing about tipping is that you have to re-learn how to ride a bike. On a conventional 2 wheeler you are use to leaning into a turn, so much so that you don't realize you are doing it. Once on a trike, it becomes readily apparent that you should not lean into the corners. It takes a couple of turns to figure out and feels unsettling at first.

The Nihola is a great trike, drum brakes on the front and disc or v-brake on the rear, 7 speed with a weather resistant cover and built in removable seat with seatbelts.
