The new Electric bikes make hills easy to climb and can reduce Car use. (mine by 30%)  This 36 Volt Cycle, with centre motor and low position Battery is ideal and makes hills easy to ride and continually pedal.

Below a Safety / Grab handle on my stairs made from 1/6 of a  Cycle wheel.

One of my best ideas. It is 1/6 of a 700c size wheel. Radical Radial ! Here used as a shelf support. It looks far more stylish than the type found in care homes.

The new 48v cordless drills are superb.
