Hi Henrik - if you want to keep the standard Sinclair motor then a 4QD 24v controller and throttle assembly will give you better hill assist and a little more top speed depending on what power setting you set the controller at.

There is a problem in that the gearbox will be damaged by the power increase.  This is why we are experimenting with metal gearbox conversions and alternative motors;

The instructions for fitting the 24v kit are still available in the c5alive download section.

Hi BooBoo

the original sinclair c5 motor is to weak, for my setup,  i want to use a 2-3000Watt motor with a 36 or 48V controller. the hole rear axle and transmission has to be rebuild so it can handle the extra power.

24v 1kw motor from an HGV tail lift. Built for ascending Test Hill at Brooklands Museum, so more for torque than outright speed.

Henrik, try the burton 250 kw engine. ;D ;D. I am afraid you loose the trunk then for some space.
You don't think. that if you build a 1 to 3 kw engine your range will be very limited?
Maybe take a look at quasimodos site www.sinclairc5.nl. he is in the proces of building a 750 watt version.
Where are you in Denmark, I'll visit the Skive Viborg area next year.
