I want an alternative to small, big and severe in this sentence.
A big accident is as much severe as a small one. The rider inevitably fall off. It's about bicycles.
I wish I had better English, but I work hard to improve it. I'm studying for IGCSE, so I'm only interested in BrE.
Your first sentence has a logic problem. A big accident is ovbviously more severe than a small one.
Better (with word substitutions) would be: A minor accident can be as devastating as a major one. The rider inevitably falls off. It's all about bicycles.
