Rottweiler’s authentic entries into the light-weight e-mountain bike category, the R.X375 and R.E375, rely upon a lithe body and compact 375-watt hour battery to be available at around 19kg (~41lbs). But they desired extra energy and longer rides without including extra weight.
The new R.X735 is the answer, doubly so to a brand new 720-watt hour custom battery, coupled to a Shimano EP8 motor, all housed in a brand new front triangle. In overall, the updates handiest upload 2kg to the bike’s claimed weight of 21kg (~46lb, length large).
It’s a 29er with 144mm rear tourer and a 150mm fork, designed to be an all-rounder for competitive riders. I located this to be nearly true, test out my overview at the lowest of this post. But first, the technical information…
Rotwild R.X735 Frame & Tech

The 375 version is available in one-of-a-kind path and enduro fashions, at the same time as the extra effective 735 is available in a path version with simply 144mm of tour. The 65.5º head perspective is paired with an extended 450mm chainstay length, giving it a barely longer wheelbase, making it very solid at velocity and on descents.
Rotwild has usually inspired me with their engineering and layout, that is why fellow German logo Porsche makes use of them to construct their bikes.
During development, Shimano vehicles had been tough to return back with the aid of using, in order that they 3D-published a placeholder so they could paint the layout.
They additionally have 3D-published body sections to check the brass battery launch button mechanism, which has a totally pleasing tactile sense and a “click” that lives as much as German car standards (near the door on a Mercedes and say you are now no longer inspired).

The battery launch button is likewise without difficulty replaceable if it ever wears out. And, there may be an o.e.m button that provides a protection screw that forestalls the button from being driven in, therefore stopping the battery from being launched until you dispose of a small bolt.

The rocker linkage makes use of a foam middle to keep weight and create an incredibly stiff carbon part. They use every other bit across the seatpost to reinforce the tube because it extends barely past the pinnacle tube. (That layout might also additionally restriction overall dropper length, however it offers you masses of standover clearance)
Elsewhere at the body, completely inner sleeves and tubes, manual shift and brake cables and hoses, making provider and instals clean and preserving matters noise-unfastened at the journey.

While the smaller R.X375 has 140mm of rear tour and receives an inline Fox shock, they have upgraded the R.X735 with 150mm of rear tour with a piggyback drift X rear shock.

The pinnacle-shelf spec at the Ultra version makes it pricier, however the Core and Pro fashions proportion the identical body and technology.
Other exceptional touches consist of a lengthy-tour, including eight PINS dropper seatpost and clearance for 29×2.6″ tires.
The new battery compartment is the primary to be launched at the proper facet of the body.
The custom energy cell is housed in a custom carbon shell that is machined right into an inflexible mandrel to make certain ideal inner dimensions…with none wiggle room to suit the batteries inside.
The R.X735 body is proven on the pinnacle, in comparison to the thinner R.X375 body with a smaller battery at the lowest.
To make room, the downtube needs to be larger than the R.X/E375 frames. So they stretched the pinnacle tube to suit the aesthetic.
This new trunk (and a few different cockpit parts) from a third celebration logo will come later. Technically those are prototypes, we can not inform you…
…however test to deliver the Di2 and motor manage wiring groove below the grip and into the handlebar, in which they cross up and down the stem via a port withinside the headset cap for a very stealthy appearance. Compared to e-bikes with more wires protruding everywhere, it is a refreshingly smooth layout. Stay tuned for extra information on those parts, as they’re now no longer specific to Rotwild.
First Rides – Rotwild R.X735 Review
I took the massive R.X735 for multiple rides across the Dolomiti Paganella Bike Park and surrounding trails, blending tough herbal terrain with groomed glide paths, berms and tree features.
It became an awesome check of the Rottweiler’s “all-rounder” claims, and indeed, the bike excelled in all respects. The rock felt stable without feeling heavy.
Maybe it is due to the fact I’m looking to preserve up with pals on lengthy tour bikes, however regardless of being undergunned with the aid of using 10-20mm of tour in comparison to the whole lot else I journey, I felt like I held down Willy Wonka for my quickest lap in this bike.
To be fair, this became my ultimate lap of the tour, so I became mastering the paths quite nicely with the aid of using them, however nevertheless a commendable overall performance for a 150mm bike towards a massive, lazy beast.
This became one of the tamer sections at the Secret Trail in which I became without a doubt using the bike brief however became capable of travelling the maximum of it.
On techy, free climbs, I felt I might gain from tucking the rear tire extra below me with shorter chainstays to offer higher traction. But that became the time once I felt the lengthy remains and wheelbase had been no longer ideal.
And I think, had I had this bike, I’d in all likelihood choose the XL… maybe… The caveat is that it provides every other 30mm to the already lengthy wheelbase, despite the fact that the chainstays stay regular at 450mm throughout all body sizes. However, the massive one became pretty manoeuvrable, so I wanted to check the journey again and again (which I advise all people to do every time possible).
Overall, I agree that Rotwild’s R.X735 is a great all-rounder. It’s a motorbike that I can position any of my pals on and they may be capable of clinging on, and it is a bike that I can take to a number of my favourite trails and feature fun with. It seems nicely built, feels stable and has terrific specs…
And you pay for it. The middle version runs €7,999, with the higher-quit Pro version at €9,499. The Ultra version (tested) with Fox manufacturing facility suspension is €12,499. It places it a piece higher than in addition specced competitors, however you are getting an excessive degree of integration, suit and end right here that is not found in each logo. Definitely really well worth a glance if it is to your price range and also you need an awesome fine eMTB to deal with any type of use.
