Parts for Senada...Where can you purchase in the USA?

Not familiar with that brand; is it high end or cheap? it's actually easier to get generic parts for cheap bikes.
Parts for hi-end bikes are often model specific & 'otfen out of stock' check back later (haha) Always the
1st thing to is contact the maker. This is often an exercise in futility that sometimes results in getting the wrong
part with no refund. (Amego?)
