It's one thing to put your own life at risk in the learning process, but it's completely unacceptable to put someone else's life at risk in the learning process.
It must be remembered that a woman doesn't have the intuitive connection to a mechanical instrument because it's not part of her life focus. A woman who purchases a motorised bicycle from a seller just expects that person to be a professional and expects the bike to give Honda reliability, furthermore, she is not looking for potential problems nor is she expecting the bike to catastrophically fail in operation.
It only took 30 seconds of looking at the conventional left hand side drive system supplied with the standard motorised bicycle kit for me to realise that it was a completely useless design which would prove to be worthless in operation.
For that reason i spent 3 weeks searching the internet to find a better system, upon which i found the SickBikeParts shift kit, which made the bike a truly usable transportation device.
Even so, i spent 2 (very painful and soul destroying) years sorting out various issues to give my bike Honda levels of reliability, though it still requires Moto Guzzi levels of maintenance time.
What hope does a woman have of receiving a reliable motorized bicycle from a person with proven levels of mechanical catastrophe; causing a potentially serious situation to her well being.
Some people just need to give up the dream of making a dollar from these bikes.
