I thought aminorjourneys tip for coasting the Twizy ought to be made a sticky topic for everyone to see.

Firstly, for anybody who isn’t aware, the Twizys regenerative battery effectively places a speed limiter on the Twizy of 52mph, even when going down the steepest of hills.
However, the way to get round this is to gently place your foot on the accelerator pedal so that it is barely being pressed. If you get it right, you will see above your speedometer on the display that no bars are highlighted, meaning that your Twizy is neither drawing power nor recharging the battery. This effectively disables the speed limiter, meaning that if you can find a really steep hill, or you approach a hill already at 52mph then you will be able to get possibly up to 60mph with a little help from gravity!
