Key Specifications of the Diamant Beryll Esprit RT Gen 3 (Einstieg: tief) 2025

Who This Fits

Riders demanding a low-maintenance, clean-operating electric bike with no chain lubrication requirements benefit from the Gates CDX carbon belt and enclosed Nexus hub. The low-step frame and foot coaster brake provide familiar, confidence-inspiring handling for everyday city riding.

Urban utility riders and leisure cyclists utilize the integrated MIK luggage platform and factory-installed Abus wheel lock for errands. The 75Nm Bosch drive unit delivers strong uphill assistance while the suspension fork and seatpost reduce body fatigue.

Compatibility and Installation

The chassis features a 100mm quick-release front axle and 135x5mm quick-release rear spacing with Post Mount disc brake tabs. The Gates CDX belt requires proper tensioning according to manufacturer parameters during rear wheel adjustments.

The Bosch Intuvia 100 display interfaces wirelessly with the Smart System LED Remote. Fast charging is supported through the included Bosch 4A 230V standard charger.
