There's some marketing advice that customers care about solving their problem and not how your solution works. I think this often gets misapplied to turn simple and comprehensible products into vague blobby messes. The customers don't care how your scooters work, but they know what scooters are. They don't know what "get your daily errands done hassle free" means.

Plus if you describe yourself in very high level terms, then your addressable market is bigger and you can get more money from investors.
