Thanks to http://www.gokart.co.uk for great customer service, a great product and their offer of support with this challenge (watch this space).
I bought my Go-Kart Electric Trolley (Mark 1, automatic) on the recommendation of a friend, some years ago and I am very happy with it. I’ve had next to no issues with it, it’s very easy to use, light and folds up nicely in the boot and, more importantly, it is still going strong. It is coping with all the weather being thrown at it recently, from the frost and fog (see below) to playing through Storms Ciara and Dennis this month (February 2020). They have sent lots of wind and rain our way as you all know (thoughts are with all the flood victims).

I was told that Go-Kart’s customer service is great and this wasn’t wrong. They’ve exceeded expectations including recently sorting out issues with a rain cover with no quibbles and making it very easy for me. Thank you.
