BMCs new Roadmachine endurance bike range sports a greater 40mm tyre clearance, down tube storage and a greater focus on improving compliance.The rear triangle has been redesigned to increase flex. The bike has an integrated rear light and a new one-piece cockpit on the flagship model.There are five options in the range starting with the Roadmachine 01 and Roadmachine. The latter uses a more cost-effective carbon construction to hit a more accessible price point.Theres also a gravel-oriented Roadmachine 01 X, with the Roadmachine X sitting beneath it.Finally, there is an updated Roadmachine AMP electric road bike. The new bike uses a TQ HPR50 motor, but the Mahle-equipped models will remain in the range for the foreseeable future.Pricing starts at 3,199 / AU$4,799 for the BMC Roadmachine Five and rises to 12,999 / AU$17,499 for the range-topping Roadmachine 01 Two.UK pricing and distribution is TBC.How does it ride? Read our BMC Roadmachine 01 Two review.Fast accelerator and 27 per cent more compliant The Roadmachine has now become a much more versatile bike with its increased tyre clearance. - Oscar Huckle / Our MediaAccording to BMC, the key aim with the third-generation Roadmachine was for it to be a fast accelerator, with controlled flex and reactive handling, all while being capable of accepting 40mm gravel bike tyres.BMC did not use its ACE supercomputer to design the new bike, instead relying on designers to achieve the desired riding properties.The new bike sees changes to the rear end. This is claimed to make the bike 27 per cent more compliant without sacrificing stiffness.The new bike bears the hallmarks of BMC design language. This includes the slightly raised triangular outside face of the top tube found on the outgoing Roadmachine, the kinked seatstays reminiscent of the Granfondo GF01, the D-shaped seatpost and ICS integrated cockpit.Kinked seatstays and a UCI-compliant seat tubeThe kinked seatstays are a nod to the Granfondo GF01. - Oscar Huckle / Our MediaThe extra compliance is mainly achieved via the redesigned rear triangle. The kinked seatstays are reminiscent of those seen on the Granfondo GF01.The seatstays are thin and BMC has also altered the tube profiles of the seat tube.The cut-out for the rear wheel has been re-sculpted to increase tyre clearance. It also has a thin wall thickness to enable lots of flex.The seat tube is thin. - Oscar Huckle / Our MediaBMCs head of R&D, Stefan Christ, said it was possible to reduce the thickness of the seat tube following a UCI rule change. Previously, the UCI mandated all tubes on the front triangle must be at least 25mm deep. This has been dropped to 10mm.The seatstays were lowered on the previous Roadmachine and remain in the same position. BMC says theyre as low as they can be while maintaining good power transfer and torsional stiffness.BMC says a thinner layup will result in additional flex at tube junctions.The weight goes up and frame storageThe frame weight is up by approximately 68g for a size 54cm. - Oscar Huckle / Our MediaBMC openly says it prioritised compliance and stiffness over reducing weight. The new Roadmachine is claimed to weigh 963g in a size 54cm with the lightest paint finish and without hardware.Thats heavier than the claimed 895g frame weight of the second-generation Roadmachine. BMC says most of the weight increase is because of adding down tube storage.Christ says maintaining stiffness while introducing frame storage was the biggest design challenge. He explains that, with a hole in the down tube, its hard to maintain the torsional stiffness of the tube. Adding additional material to ensure stiffness increases weight.A lot of work has gone into the fork, too. - Oscar Huckle / Our MediaThe new fork is claimed to 448g (with the steerer tube uncut). The outgoing fork was claimed to weigh 380g but BMC says this was with the steerer cut to an unspecified measurement.The second-tier Roadmachine is claimed to weigh 1,150g (also in a size 54 with the lightest paintjob). The matching fork weighs 480g.BMC says the cheaper frames offer the same riding characteristics but the increased weight is because of the different construction.40mm tyre clearanceBMC reckons you'll fit a tyre with up to a 40mm measured width with 4mm to spare. - Oscar Huckle / Our MediaThe Roadmachines 40mm tyre clearance is generous for an endurance road bike, with only the Specialized Roubaix SL8 matching it.For comparison, the Trek Domane SLR is rated to 38mm tyres, with the Canyon Endurace and Pinarello Dogma X topping out at 35mm.The Roadmachine achieves its generous 40mm tyre clearance with heavy sculpting around the seatstay junction and fork crown.Inspired by the BMC Kaius gravel race bike, the fork leg thickness has been reduced to increase clearance.BMC's sticking with a BB86 press-fit standard. - Oscar Huckle / Our MediaBMC says speccing a BB86 press-fit bottom bracket standard was also a key factor because a BSA threaded unit is wider.BMC says it would have been possible to increase tyre clearance further but this would have increased the rear-centre length something it didnt want to do.Stealth Dropouts and finishing touchesThe bike inherits BMC's Stealth Dropouts. - Oscar Huckle / Our MediaThe Roadmachine inherits BMC's Stealth Dropouts, which debuted on the fourth-generation Teammachine SLR01. These see an in-moulded captive nut bonded inside the dropout, resulting in a clean finish said to improve aerodynamics.The front derailleur hanger is removable. - Oscar Huckle / Our MediaThe new Roadmachine is compatible with both 2x and 1x drivetrains.The Roadmachine and Roadmachine X can also accept mechanical groupsets, but the premium Roadmachine 01 and Roadmachine 01 X are only compatible with electronic groupsets.There are mounts on the top tube for a bento box and the bike uses BMCs Aerocore bottle cage design to improve aerodynamics.There are top tube mounts for a bento box. - Oscar Huckle / Our MediaTheres an integrated chain catcher, too. BMC installs protective tape as standard around the bottom bracket shell to prevent paint damage.The Roadmachine 01 X and Roadmachine X feature additional protection tape under the down tube to protect against rock strikes.The seatpost is D-shaped. - Oscar Huckle / Our MediaThe D-shaped seatpost from the outgoing Roadmachine is retained on the new model. It is also used on the URS and Kaius. It is claimed to weigh 179g. A 15mm offset is specced as standard but a zero offset seatpost is available aftermarket.Like other BMC models, there is a direct mount hanger available for Shimano groupsets and a separate derailleur hanger for SRAM.Down tube storageThere's a switch at the top of the bottle cage to access the down tube storage. - Oscar Huckle / Our MediaBMC uses a modified Aerocore bottle cage on the down tube. Rotating a switch beneath thisopens the door to the integrated down tube storage.A pouch for holding tools and spares is included with the 01 models and is available after-market for other models.There is a pouch tucked in underneath the hatch. - Oscar Huckle / Our MediaDown tube storage is becoming commonplace on many of the best mountain bikes, and its appearing on gravel bikes too. Uptake on road bikes has been slower, with the Trek Domane SLR the most notable example to feature it to date.Because of the down tube storage, hoses are guided through the down tube to prevent them from being crushed.The down tube storage compartment is claimed to be water-repellent, rather than waterproof.Mudguard mountsThe Roadmachine and Roadmachine X feature mudguard mounts.You can also mount BMCs D-Fender mudguard on the saddle rails. This is similar to an AssSaver, albeit slightly longer and wider to increase coverage.The Roadmachine 01 models do not feature mudguard mounts but BMC says the tubes can accept the extra stress, and has tested them with clip-on mudguards.Integrated rear lightThere's an integrated rear light. - Oscar Huckle / Our MediaThe Roadmachine features an integrated 20-lumen StVZO USB-chargeable rear bike light with a claimed 90-minute run time. A similar light debuted on BMC's Roadmachine AMP and Speedmachine. It sits behind the seatpost and can be attached or removed.The light is provided as stock on 01 bikes and can be purchased separately for others.A new handlebarThe new ICS Carbon Evo cockpit aims to further improve comfort and control. - Oscar Huckle / Our MediaThe Roadmachine continues to use BMCs ICS handlebar and stem, with the hydraulic hoses running down the flat faces of the forks steerer.The new ICS Carbon Evo cockpit debuts on the Roadmachine 01 Two.The new bar features a reshaped drop for less hand fatigue and an ergonomic shape along the tops, according to BMC.The drops have an 8-degree flare. - Oscar Huckle / Our MediaThe cockpit has a 135mm drop, a short 65mm reach and an 8-degree flare. It is available in 70 to 120 stem lengths in 10mm increments. Only one width option is available (40cm centre-to-centre on the top, flaring to 44cm on the drops).BMC says additional widths will be coming soon. The bar-stem will be available aftermarket for 699 / $699.BMC says its up to the dealer if theyre happy to swap the stock bar for a different size at the point of purchase.You'll find the ICS MTT suspension stem on the gravel models. - Oscar Huckle / Our MediaThe Roadmachine models feature a more typical separate ICS stem and handlebar combo.The Roadmachine 01 X and Roadmachine X use BMCs ICS MTT Suspension Stem, which provides up to 20mm of tunable suspension via an elastomer setup designed in collaboration with Redshift.BMC Roadmachine geometryBMC wanted the chainstays to be as short as possible. - Oscar Huckle / Our MediaThe Roadmachine has a shorter rear centre, higher stack and shorter reach than the previous generation. All sizes have a trail figure of 63mm. BMC says it wanted this number to be shared across all sizes to maintain the same riding characteristics.The head tube angle is slackened slightly on the two smallest sizes to prevent toe overlap.As a result of the increase in tyre clearance, chainstay length has grown to 415mm across all sizes, though the overall wheelbase only increases by 1 to 3mm depending on size. 47cm51cm54cm56cm58cm61cm Head tube angle (degrees)71.471.472.272.272.272.2 Head tube length (mm)112138154181207233 Seat tube angle (degrees)74.274.274.274.274.274.2 Seat tube length (mm)414461488508529550 Top tube length (mm)520537546559571581 Rear centre (mm)415415415415415415 Wheelbase (mm)9821,0009971,0101,0231,036 Bottom bracket drop (mm)757575757575 Fork rake (mm()505045454545 Trail (mm)636363636363 Reach (mm)370379383388393398 Stack (mm)525550570595620645 Edit Table BMC Roadmachine AMPThe Roadmachine AMP is built around a TQ HPR50 motor. - Oscar Huckle / Our MediaBMC is concurrently launching the Roadmachine AMP an electric road bike with a TQ HPR50 motor.The brand says it partnered with TQ because the motors are quieter than the hub-based Mahle option it previously used.BMC wanted to go for as quiet a motor as possible. - Oscar Huckle / Our MediaCompared to the non-assisted bikes, you dont get the Aerocore bottle cages or down tube storage because the battery is housed inside the down tube.You may remember Mavics X-Tend prototype motor that senior technical editor Ashley Quinlan had a first ride on last year on a modified BMC Teammachine SLR01.BikeRadar asked BMC if it intended to use Mavic motors in the future.BMC said its still working closely with Mavic but progress has been slow and the original 2025 to 2026 deadline is unlikely to be met.BMC Roadmachine models and availabilityBMC Roadmachine 01BMC Roadmachine 01 TwoThe Roadmachine 01 Two is the top road offering. - Oscar Huckle / Our MediaGroupset: Shimano Dura-Ace Di2Wheelset: DT Swiss ERC 1100Claimed weight: 7.1kgPrice: 12,999 / $12,999 / AU$17,499BMC Roadmachine 01 ThreeGroupset: SRAM Force eTap AXSWheelset: CRD-321 SLClaimed weight: 7.8kgPrice: 8,499 / $8,499 / AU$11,499BMC Roadmachine 01 FourGroupset: Shimano Ultegra Di2Wheelset: CRD-321Claimed weight: 7.9kgPrice: 7,999 / $7,999 / AU$10,999BMC RoadmachineBMC Roadmachine TwoGroupset: Shimano Ultegra Di2Wheelset: XRD-522Claimed weight: 8.2kgPrice: 5,499 / $5,499 / AU$7,499BMC Roadmachine FourGroupset: Shimano 105 Di2Wheelset: Mavic Open DiscClaimed weight: 8.6kgPrice: 4,199 / $4,199 / AU$5,999BMC Roadmachine FiveGroupset: Shimano 105Wheelset: Mavic Open DiscClaimed weight: 8.8kgPrice: 3,199 / $3,199 / AU$4,799BMC Roadmachine 01 XBMC Roadmachine 01 X OneThis is the top-of-the-range Roadmachine 01 X One. - Oscar Huckle / Our MediaGroupset: SRAM Force XPLR AXS, 1x12Wheelset: CRD-321Claimed weight: 8.4kgPrice: 7,999 / $7,999 / N/A in AustraliaBMC Roadmachine XBMC Roadmachine X TwoGroupset: SRAM Rival eTap AXS, 1x12Wheelset: XRD-522Claimed weight: 8.8kgPrice: 4,799 / $4,799 / N/A in AustraliaBMC Roadmachine X ThreeGroupset: SRAM Apex XPLR AXS, 1x12Wheelset: XRD-522Claimed weight: 8.9kgPrice: 4,299 / $4,299 / N/A in AustraliaBMC Roadmachine 01 AMPBMC Roadmachine 01 AMP OneGroupset: Shimano Ultegra Di2Wheelset: CRD-400SLClaimed weight: 12.5kgPrice: 8,999 / $8,999 / N/A in AustraliaBMC Roadmachine 01 AMP TwoThe Roadmachine 01 AMP Two is specced with Shimano GRX Di2 and 32mm Pirelli Cinturato Velo tyres. - Oscar Huckle / Our MediaGroupset: Shimano GRX Di2Wheelset: CRD-400Claimed weight: 12.8kgPrice: 7,999 / $7,999 / N/A in AustraliaBMC Roadmachine 01 AMP ThreeGroupset: Shimano 105 Di2Wheelset: XRD-522Claimed weight: 13.1kgPrice: 7,999 / $7,999 / N/A in AustraliaBMC Roadmachine 01 AMP XGroupset: SRAM Force AXSWheelset: CRD-400Claimed weight: N/APrice: 8,999 / $8,999 / N/A in Australia
