Replacing our current e-MTB supplier — 80-unit qualification order first

Our current factory for this sport e-MTB category has been slipping on quality control over the last several shipments, and we are lining up an alternative before our next big reorder locks us in again. Before committing to a full switch we want a qualification order of 80 units to check build quality, paint finish and ride feel against our current supplier's output. If it passes our shop network's evaluation, this becomes a recurring account. The bike itself: steel frame with front suspension fork, 7-speed drivetrain, 27.5" wheels, brushless rear hub motor (36V/250W), 36V/7.8Ah lithium battery in the down tube, mechanical disc brakes, 30-40km range per charge. What we need on this order: - Same spec as your standard configuration, no custom branding for this qualification batch - CE or UL certification documentation for the motor/battery system - Standard export carton, partial assembly is fine Delivery: FOB your nearest port, we handle freight to Colorado ourselves. Please quote unit price for 80 units, confirm current lead time from PO to ready-for-pickup, and let us know your standard pricing tiers if this moves to a recurring account at higher volume.
