Why is the Roller constructed of Aluminium Alloy?
There are several reasons why the Roller is built of aluminium alloy: (a) It doesn’t rust – this is a very important advantage over steel. When you have paid a considerable sum of money for a machine designed to be used outside, on the road, in all weathers and conditions, it seems unreasonable for the most expensive part, the chassis, to be prone to rusting. (b) It is possible to construct light and stiff structures. Stiffness with minimum weight is important in a trike – you don’t want to waste energy flexing the chassis with each push on the pedals nor carry unnecessary weight up the hills. (c) The Roller chassis is built with an alloy known as 6082-T6. It is the European equivalent of the better known 6061 used in the USA and is widely used in many structural applications, aircraft fittings, cameras, marine and electrical hardware, hydraulic pistons, etc. It has a high strength-to-weight ratio, is very corrosion resistant and welds together with predictability when using the correc
