Rotwild presented the R.X735 just last year. With this bike, they managed the balancing act between the Light E-MTB R.X375 and E-Enduro R.X750. Now the R.E735 is coming onto the market - with more suspension travel than its little brother, the R.X735. The E-Enduro has also been given a flatter, downhill-orientated geometry to offer more safety. For the necessary agility, the e-bike has a mullet set-up (29-inch front/27.5-inch rear). This also shortens the length of the chainstays. Another highlight is the low weight of 21.6 kilograms. That's just 200 grams more than its little brother, the R.X735.

Motor and battery on the Rotwild R.E735
Motor - Shimano EP801
The new Rotwild R.E735 is fitted with the new Shimano EP801 motor. From the outside, it looks exactly like its predecessor, the EP800. But there is new technology inside. The drive is now compatible with the new Shimano DI2 compatible. However, the new electronics also mean that old batteries are no longer compatible with the new system. In addition to the new updates, the EP801 e-bike motor is also said to have increased in power. Instead of 500, it should be able to push 600 watts.
Battery
As already known from the other models, the battery size can be read from the model name. At least almost. The battery in the R.E735 effectively offers 720 watt hours. The battery sits in a carbon housing and fits harmoniously into the down tube. It weighs 3.5 kilograms. With the help of the Rotwild "Quick Release", the battery can be removed at the touch of a button and can therefore also be charged externally.
Frame and geometry of the R.E735
Frame
The frame of the new Rotwild R.E735 is made entirely of high-modulus fibre carbon. Only the shock yoke is made of aluminium. The entire frame design and the choice of add-on parts are ultimately designed for a low overall weight. The "Ultra" version of the Rotwild R.E735 weighs just 21.6 kg.
Geometry
Compared to its smaller brother, the R.X735, the reach in size L shrinks by 10 millimetres to 465 millimetres. For a current enduro bike, this value is extremely short for an L-frame. On the other hand, the head angle has been slackened by one degree. It is now 64.5 degrees. The seat angle of 74 degrees is rather moderate for current geometries. Thanks to the mullet conversion, the chainstay length has been shortened to 440 millimetres, which has a positive effect on the agility of the bike.
Model overview Rotwild R.E735
Rotwild R.E735 "Core" model
The "Core" equipment relies on a Fox 36 Float Performance suspension fork with grip cartridge and 170 millimetres of travel. At the rear is a Fox Float X2 shock with 150 millimetres of travel. Gears are shifted with a Shimano XT drivetrain. Braking power is provided by a Magura MT5 with thick 220/203 millimetre brake discs. For the necessary grip, Schwalbe Magic Mary 2.4-inch tyres are fitted at the front and Hans Dampf 2.6-inch tyres at the rear. The bike costs 8999 euros.
Rotwild R.E735 "Ultra" model
The € 11,499 "Ultra" model comes with a Fox 38 Factory Grip2 Kashima fork, also with 170 millimetres of travel. Instead of the Performance version, the Fox Float X2 shock is now fitted in the Factory Kashima version. The shifting system also relies on the faithful services of the Shimano XT. The brakes are also a Shimano XT 4-piston system. To further reduce the weight, Crankbrothers Synthesis Enduro Carbon wheels are fitted to the Rotwild.
