625 watt hours, 140 millimetres of suspension travel, 21.5 kilos: these are the specs of Conway's latest E-Fully. The Xyron comes in an aluminium and a carbon version.

The E-MTB full-suspension bikes presented so far with new Bosch drive did not exactly shine with their particularly low weight. Of course, the Powertube integration and the larger battery (625 watt hours) don't exactly make lightweight construction easy. Positive outlier: Conway's brand new full carbon speedster Xyron Carbon. Our scales stopped at 21.5 kilos for a pre-production model that does not come with the standard equipment. Without carbon wheels and designated lightweight parts, but with solid supergravity rear tyres and a 625 watt-hour battery. A strong value. The top model comes even better - presumably lighter - equipped as standard.

  The frame of the Xyron Carbon is made entirely of carbon: main frame, rear triangle, rocker link. That really saves pounds. The bearings of the rocker disappear neatly inside.Photo: Robert Niedring The frame of the Xyron Carbon is made entirely of carbon: main frame, rear triangle, rocker link. That really saves pounds.

The geometry of the Conway Xyron

As an all-rounder, the Xyron is intended to appeal to both touring riders and sporty trail bikers. The geometry is modern, but not exaggerated. The carbon model differs slightly from the aluminium version. With a longer reach and shorter head tube, the lightweight model has a sportier design. The head angle for both versions is 66 degrees, the seat angle 75 degrees. With a reach of 457 mm (aluminium) or 469 mm (carbon), the bike should also be equipped for demanding terrain and offer sufficient freedom of movement. The chainstays end up at a medium-length 450 millimetres, a dimension that can currently be found on many modern e-mountainbikes.

The equipment variants of the Conway Xyron

The carbon Xyrons are available in three variants, all with a 625 Powertube battery. The 727 model starts at 5299 euros. It comes with Fox suspension (36 Performance Float), 12-speed NX Eagle drivetrain, affordable four-piston brakes from Shimano and a solid Schwalbe tyre combination of Magic Mary and Hans Dampf. The Xyron 827 Carbon is available for 6000 euros, which is upgraded compared to the cheapest model with a 12-speed Shimano XT drivetrain, XT four-piston brakes and a wheelset from DT Swiss. The top-of-the-range 927 model costs a whopping €8,000, for which it reaches into the highest Rockshox shelf and features a Pike Ultimate fork and Superdeluxe Ultimate shock. Gears are shifted with a Sram 12-speed Eagle AXS even electronically and wirelessly. Deceleration is provided by Sram's Code brakes.

The aluminium versions are priced between 3700 and 5200 euros. The most expensive model (Xyron 527) is equipped with Fox Float performance suspension, 12-speed Shimano XT gears, XT four-piston brakes and DT Swiss wheels. The Xyron 227 is the most affordable model in the range. Here, a 500 Wh power pack is used, which is inserted into the down tube from above. It also comes with Rockshox suspension (Recon RL, Deluxe Select Plus shock), Shimano Deore gears and Tektro Orion brakes.

All-round is the trump card

The aluminium version of the Conway Xyron is fully prepared for the installation of mudguards, kickstand, pannier rack and lights. Two equipment variants roll into the shops fully equipped ex works. This means that the Xyron is also suitable for commuters, touring cyclists and all-rounders who rarely tackle trails and off-road riding and see the e-MTB more as a comfortable all-round vehicle. The two models Xyron C 227 and 427 cost 3900 and 4600 euros respectively.

Cairon S - Conway's entry into the new Bosch class

Conway also has a hardtail series with the new Bosch Performance CX in its programme. Similar to the Xyron, the expensive models rely on the 625 Powertube battery, while the affordable bikes have a 500 power pack semi-integrated into the down tube. The frame is made of aluminium. The Cairon models are all available in both 27.5 and 29 inch versions and also in step-through and fully equipped versions with mudguards, pannier rack, light and side stand. The Cairon is available from 2400 euros, the top model costs 4000 euros.

Florentin Vesenbeckh has been on a mountain bike since he was ten years old. Even on his very first tour, he focussed on single trails - and even after more than 30 years in the saddle of an MTB, these are still the quintessence of biking for him. He spent his youth competing in various bike disciplines and later his cycling career was characterised by years as a riding technique coach. Professionally, the experienced test editor now focusses on e-mountainbikes. In recent years, the qualified sports scientist and trained journalist has tested over 300 bikes and more than 40 different motor systems in the laboratory and in practice.
