Description

With a powerful motor, extended electric range, and high load capacity, it’s designed for riders who need reliability, comfort, and performance for daily use and longer journeys.
High-Speed Motor Performance
Powered by a 750W high-speed motor, the DM427 delivers strong acceleration and confident cruising performance. With a top speed of up to 50 km/h, it’s well suited to longer commutes and efficient urban travel where permitted.
