UD4 ALL TERRAIN
from € 5,990
“All Terrain” is the universal pedelc for both city and countryside. It is available in black (matt), red (matt) and white – and with HNF’s signature combination of carbon belt and continuously variable transmission. We have equipped it to the fullest with the most attractive components of the upper premium segment. All details and specifications are available here:

UD4 ALL TERRAIN ROHLOFF
from € 7,490
“All Terrain Rohloff” is HNF’s top highlight, both technically and visually. The classic British Racing Green unmistakably signals that this bike is “a class of its own”. Equipped with the best premium components, built to last. In the drivetrain, the unique Rohloff Speedhub 500 e14 gearbox performs superbly, combined of course with the maintenance-free Gates CDX carbon belt.

UD4 ADVENTURE
from € 5,490
At HNF, “Adventure” stands for the premium version with chain drive – and with otherwise unchanged components from the upper premium segment. If you ride your bike less than 2,000 km a year, but still don’t want to miss out on high-quality components, you might be better off with this drivetrain – not least due to the lower entry price as compared to the belt models. The same applies, of course, to those who prefer the chain for traditional reasons.

UD4 ECO TOURING
from € 4,690
At HNF, “ECO TOURING” stands for premium quality with chain drive – at a slightly reduced scope of components and improved suitability for unpaved roads. For example, if you are looking for off-road capability and can do without the integrated folding lock and a centrally positioned display, this variant offers exactly the same premium quality as all the other variants, despite the lower price. The scope of its components is still extensive.

Quality without compromise.
A timeless and reduced design language has always been a central feature of our bikes, which are as robust as they are manufactured to a high standard. Today, HNF stands as a symbol for the pioneering achievements behind our advanced drive concept: We preferably combine the powerful and everlasting Bosch motors with a long-life belt drive and a continuously variable transmission. This combination, which we first introduced in 2015 with the XD series, is today considered the gold standard for maintenance-free operation across all manufacturers. Since 2022, we have also been adding high-quality chain drives and gears to our product range, enabling us to serve broader market segments.
