Priced at 5,990 EUR, this model offers high-quality fittings and robust technical specifications.

The braking system comprises Magura brakes, with an MT5 203mm brake at the front and an MT4 180mm brake at the rear, ensuring reliable braking performance. The Enviolo CVP TR gear system, featuring an Enviolo CT Pure twist grip, allows for stepless adjustment of the 99 gears, ensuring a smooth adaptation to different terrains. The RockShox Recon Silver fork with 100mm of travel improves riding comfort on uneven terrain.
Visibility is ensured by the Supernova Mini 2 front light and the Supernova M99 TL3 Pro Max rear light with integrated brake light. The spec is rounded off by VP Components VPE-527 pedals and a Gates CDX drivetrain, comprising a 55T crankset with bashguard, a 24T sprocket and a 125T drive.
The handlebars are Ergotec Low Riser Bars, 650mm wide with a 30° angle, fitted with Ergon GP10 L grips for a better grip. The adjustable Ergotec Sepia XL FI 50 stem allows for individual adjustment of the riding position. The Ryde Andra 29 rims and WTB Groov-E FG tyres offer stability and traction on a variety of surfaces.
The Selle Royal ON Moderate saddle, combined with the Ergotec Atar seatpost, ensures comfort on long rides. Mudguards made from HNF aluminium multi-cavity extrusion protect against dirt and water, whilst the Pletscher Optima Flex kickstand makes it easier to park the bike. An Abus Bordo Granit folding lock provides protection against theft.
For added functionality, the bike is fitted with a Racktime luggage rack capable of carrying up to 25 kg. The powerful Bosch Smart System Performance Line CX motor, combined with a Bosch PowerTube battery with a capacity of 750 Wh, provides ample assistance over long distances. The Bosch Kiox 300 display offers intuitive control and monitoring of the system.
With a seat tube length of 510 mm, a reach of 462 mm and a stack of 696 mm, the UD4 All Terrain is designed for an ergonomic riding position that offers both comfort and control. This e-bike is an excellent choice for riders looking for a robust and well-equipped model for a wide range of uses.
