Hello from Tasmania
Glad to find there was a forum on this subject !
I am new to the motorised bicycle scene, but have been keen on the idea for a few years.
I ride a non motorised bike to work and will continue to do so for the exercise.
But I have an old mountain bike I call "Clyde" because it is big and strong like a Clysdale horse.
I have added a ZBOX 50 CC engine to Clyde which has been a fun process and I am still in the running in period (Also learning how to ride it safely).
I will be asking questions on how to make the engine more quiet (hearing cars coming from behind is a real plus).
