“E-bicycle manufacturers and importers in North America and Latin America continue to struggle with a weak distribution network and modest demand,”
Not just the Americas. While the Europe e-bike market is growing rapidly, it's still tiny. And it really hasn't been integrated into the general bicycle market with both retailers and consumers turning their noses up at it.

While this has resulted in extremely low-cost e-bicycles in China, it has also led to a number of challenges including e-bicycle traffic congestion, lead contamination, and manufacturers effectively ignoring laws relating to e-bicycles speed and weight limits.
