In late 2017 Peter contacted us and asked if we would be interested in building him a Newton tricycle. For those who don't know a Newton (sometimes called a Tadpole) tricycle has two front wheels and one rear wheel. The advantages of this layout mean the rear of the trike is the same as a bicycle and doesn't need any special parts for the drive train. The front, on the other hand, is very different and requires careful design to get the handling correct, as well as special hubs.
It was a steep learning curve, but after much consideration, redrawing, building prototypes and testing we arrived at what became The Stingray. Phil Wood made us the front hubs, a Rohloff hub provided the gearing, Hope hydraulic brakes (two brakes off one lever) stop the trike and a cable operated rear disc brake with a BMX freestyle lever act as a parking brake.
The frame is made of a mix of Reynolds 853, 631 tandem tubing and stainless steel. The steering parts were made in our workshop in stainless steel and use racing go-kart con rods to connect every thing.
The custom frame bag was made for us by Moatt Sails, a local sail maker.
