With regards to the supply of bicycle engine kits in Canada from Canadian sellers... Daemon Bikes - Site taken down Tsunami Bike - Site up, engine kits in stock @ $150 ea. 80cc Motorboys - Site up, engine kits in stock, limited quantity @ $200 ea. Zoom Bicycles - Site up, no engine kits in stock Unless a bicycle engine kit's engine meets the EPA 40-CFR-1051 rating and is labeled as such it will not be granted entry into Canada in 2011 and onwards. From what I can see only YuanDong SkyHawk engines are certified to meet the latest and greatest EPA rating mentioned. No Canadian suppliers that I am aware of are selling YuanDong SkyHawk brand engines at this time. If you live in Canada and you are in need of an engine kit do check out one of the suppliers above that still have some of the older EPA spec kits in stock. If you live in Canada and plan to buy and import an engine kit from the USA do make sure it's a YuanDong SkyHawk brand that meets the 40-CFR-1051 EPA specs or it's likely it will be denied entry into Canada. .
