What we love
- Bosch Cargo Line is purpose-built for load
- Stands upright when parked, and Gen 3 adds folding decks and optional ABS
- Endless accessory ecosystem (kid seats, panniers, captain's chairs)
What we'd change
- The Gen 3 price jump is real — $7,999 before accessories
- 20" wheels feel jittery at speed
