Hi there, im looking at purchasing my first bike, and on the local pages I found this on kijiji:

I was considering this bike, as it would be ideal for my needs. I want the bike that I can basically ride on the roads then go off road with. Also with a 17 tooth sprocket on it I should be able to go highway speeds.

What I was wondering is if anyone had any experience, or any idea where I could get a reliable parts base. Or if I can even get the thing registered as street legal in canada.

Any advice would be appreciated. Thank you.
