motorINmyFUTURE,
My interpretation and experience of Alberta rules, regulations and laws regarding the motor assisted bicycle should be used only lightly. I encourage you and any one else interested in the hobby to approach the local police for clarity and direction.
In the Province of Alberta, a bicycle is a bicycle. It does not matter what cc the engine may be or even of the bicycle is solar powered.
The rules, regulations, and laws for motor vehicles do not apply to the bicycle. However the rules, regulations and laws for bicycle operation applies.
The motor vehicle act and transportation laws are focused on manufactured vehicles. This is why in Alberta the new rules, regulations and laws only apply to manufactured electric bikes and mopeds. Motor assisted bicycles are kits. If the bicycle is manufactured with an engine, it is a moped. A moped manufacturer has to follow DOT regulations. A hobbiest who builds a motor assisted bicycle still has a bicycle.
Other provinces are too nervous or cowardly to allow these garage creations on the road. Because they are not identified anywhere in the motor vehicle act in Canada, Provinces practice their right to adjust the laws to serve them. ICBC in British Columbia is one entity that condemns motor assisted bicycles.
So, approach your local traffic sergeant where ever you are and ensure that you are safe within the municipality or city bylaws with engine size.
I have a "49 cc" 4 stroke and I keep the speed reasonable. I have put 250km's so far on the city streets of Edmonton with no problems.
Enjoy the hobby while we can, be safe, and do not be a dick on the streets.
Happy riding.
