Afternoon prd you can't always protect stupid from doing stupid. A few months ago I sold a Greenfield Stallion on ebay and when I saw the postcode I contacted the seller to tell them that I didn't think it would be suitable because that postcode is all hills, up one side and down the other. The stallion has a forward/reverse gearbox not heel and toe which you can ease into reverse to slow down. The woman rang me and thanked me for telling her and 10 minutes later she rang back saying her husband said it would be fine. He came and picked it up and a week later he rang me to ask if I could fit a brake on it because he got into a situation , rolling backwards down a hill and had to crash it into a tree to stop. I ended up fitting a disc brake on it that works well, but a massive job. Without a brake these things become a billy cart
