Good times on the R.E735 

A versatile and innovative All Mountain E-MTB with maximum maximum battery performance with minimum installation space and weight. Thanks to the quick release system, the battery battery replacement is possible without any problems. Despite its powerful battery battery, the bike weighs only approx. 21.2 kg (ULTRA). Its modern geometry makes it the most versatile companion for any terrain, from technical trails to adrenaline-filled descents.

„The bike is lively and agile on trails, steers precisely through corners with a lot of pressure on the front wheel and craves speed“ 

EMTB 2022

New linkage construction

The characteristic damper linkage of the R.X735 is partly made of carbon in high-modulus fiber and a weight-optimized aluminum yoke.

ROTWILD IPU735

The target group-specific energy storage with a battery capacity of 720 Wh features high-performance cell technology (type 21700/5.0 Ah), a weight-optimized, handmade carbon housing with a low-positioned weight of 3.6 kg.

Quick Release [IPU735]

The battery of the IPU735 can be unlocked in seconds at the push of a button and easily removed. To prevent theft, the button can be blocked by means of a supplementary screw.

Shimano EP801

Maximum acceleration and efficient pedaling with natural driving feel guarantees the Shimano Motor with just under 2,500 g, 85 Nm, low pedaling resistance, high motor efficiency at low noise levels and seamless fade-out / fade-in at the support limit. In addition, the support mode can be configured via three different maps.

„The sensitive rear suspension generates massive traction“

"An important model!"

"An important model!"

It is an all-rounder par excellence: our new R.X735. It craves altitude meters, but also comes along on the trail as a king. A contradiction? Not at all - as designer Lutz Scheffer explains.

Full focus on the details

EMTB tests the new R.X735. A new E-MTB for a certain type of rider. That, at least, is a conclusion drawn by the editor-in-chief of EMTB, Josh Welz.
