Electric Bike Parts Supplier Needed

I'm seeking a supplier providing both motor and controller parts for electric bikes, in addition to belts, bearings, and bolt replacements. My location is Europe and I'm interested in making a medium-sized order of 50-100 units. The ideal candidate would have prior experience in sourcing and supplying e-bike parts and a proven track record of reliable, quality service. A strong logistical background and understanding of European supply routes will also be an advantage.
