Congrats bud!
A friend of mine rode the Pegaso a few years back. The bike itself was solid but he had some issues with aftersale service. It was some or other warranty claim that he struggled with if I recall correctly but it could have been an isolated incident.
I'd advise you to read some online reviews on the Shiver. Also search through posts on bike forums. Youtube has reviews on just about every make and model of bike. And then ask around about aftersale service on South African bike forums and Facebook groups. The folks over on
www.wilddog.za.net are generally a helpful and knowledgable bunch in my experience.
