Getting spares for one of these type bikes will never be easy because there's too many people in the chain. If you look at something like a Wisper, they carry certain parts as spares, kept in a warehouse ready to ship out at a moment's notice. near to those spares are boxes full of new bikes waiting for distribution. If anybody calls for an unusual spare part, they can always take one of one of the unsold bikes and get the Chinese to stick a replacement part in the next delivery to make that bike good again.
With Scott bikes and similar, virtually every bike that comes into the country already has a dealer's name on it, so spares have to come all the way up the supply chain. There's so many different bikes in the catalogue and they're changing all the time, so it wouldn't be economical to stock all parts as spares. Compare that with say Oxygen, who only have three bikes in their range, and two of those are virtually the same.
Years ago, I ordered some steering head bearings for a Honda motorbike from a local bike shop. They ordered them from PFK Ling, the Honda motorbikes parts distributor. When they came, I could see serious wear in them. The shop washed his hands of the matter and refused to help, so I took it up with Lings. During the conversation, they told me that they got most of their spares by dismantling complete new bikes because that was the cheapest way they could get them. They couldn't explain how used parts got into their stock, but they sent me some new replacements anyway. Giving them the benefit of the doubt, maybe an employee was refurbishing bikes at their expense, by swapping his worn out parts for the new parts in the stock.
