The Delta is a variant of the Sigma. Thanks to the straight handlebar with a lower rise and the Vaia saddle, the riding position is sportier. In addition, this one is finished in a copper/black color scheme. The low-maintenance, high-quality Gates CDX belt drive, combined with Enviolo's continuously variable hub gear, ensures smooth power transfer. Through various ride programs, you can choose the desired assistance from the powerful motor, such as the walk assist function. Thanks to the generous battery capacity (700 Wh), a range of 100 km is realistic under average use, and even well over 150 km under favorable conditions. The battery can be easily removed without a key via the menu and has a convenient handle. The illuminated control panel is located directly next to the handle, ensuring ergonomic operation. The luxurious color display is easy to detach and works as an immobilizer because the motor only works with your own display. In the basic view, the concise menu is easy to operate; if you select the advanced view, there are extra options and settings. The robust suspension fork has 60 mm of travel and provides a lot of comfort and stability.
