The Roadmachine AMP switches to a TQ HPR50 motor for a quieter life <\/p>

The Roadmachine 01 AMP Two is the electric road bike in BMC\u2019s revamped endurance bike range, with 38mm tyre clearance and a newly adopted TQ HPR50 motor, chosen for its light weight and quiet operation.<\/p>

BMC updated its Roadmachine range<\/a> in April, with the new bikes now sporting clearance for voluminous 40mm tyres, in addition to integrated down tube storage.\u00a0<\/p>

BMC concurrently released its Roadmachine AMP electric road bike<\/a> platform. While it misses out on some of the bells and whistles of its non-assisted siblings, and its clearance is a smidge tighter at 38mm, there are plenty of interesting details afoot, particularly in the frame design.\u00a0<\/p>

Goodbye Mahle, hello TQ\u00a0<\/h2>

BMC used Mahle\u2019s X20 hub-based motor on its outgoing Roadmachine AMP<\/a>, but the brand says it has made the switch to TQ because the motors are quieter.\u00a0<\/p>
The Roadmachine AMP uses the TQ HPR50 electric bike motor<\/a>, which provides 50Nm of torque and is claimed to be one of the lightest, quietest and most compact systems on the market.\u00a0<\/p>
The lower torque is also claimed to be more natural to ride than more powerful motors. We\u2019ve found that to be the case with the TQ-equipped bikes we\u2019ve reviewed so far, including the Trek Fuel EXe<\/a> and the Scott Lumen eRIDE<\/a>.\u00a0<\/p>
$\"TQ$
You cycle through the modes using the top tube display. – Oscar Huckle \/ Our Media<\/figcaption><\/figure>
A display is integrated into the top tube, where you can cycle through the various motor modes and monitor battery life.\u00a0<\/p>
A neat feature on the Roadmachine 01 AMP is there aren\u2019t any ancillary buttons awkwardly integrated into the shifter, as there are on the Trek Domane+<\/a> for example. This gives the cockpit area a much cleaner appearance.\u00a0<\/p>
$\"TQ$
You need to use conventional bottle cages instead because the battery takes up the down tube space. – Oscar Huckle \/ Our Media<\/figcaption><\/figure>
The new electric road bike\u2019s battery is in its down tube. This means you miss out on the down tube storage and Aerocore bottle cages found on its non-electric equivalents.\u00a0<\/p>
Neat frame details\u00a0\u00a0<\/h2>
$\"BMC$
The kinked seatstays are reminiscent of the brand’s Granfondo GF01, which predates the Roadmachine. – Oscar Huckle \/ Our Media<\/figcaption><\/figure>
The Roadmachine 01 AMP frame uses BMC\u2019s top-flight Premium Carbon, with the rear end heavily revised to increase compliance.\u00a0<\/p>
The Stealth Dropouts hide the thru-axle insert in a captive nut, which is bonded in the dropout. The design looks seriously clean and is claimed to improve aerodynamics.\u00a0<\/p>

Those dropouts look very clean. – Oscar Huckle \/ Our Media<\/figcaption><\/figure>
The tyre clearance on the Roadmachine AMP is slightly less generous than the non-assisted Roadmachine\u2019s at 38mm. According to BMC, this is because of shifting design trends between the non-assisted and electric variants’ development timelines.\u00a0<\/p>
The electric Roadmachine has the same D-shaped carbon seatpost as the non-assisted version. The same post is found on the brand\u2019s URS<\/a> and Kaius<\/a> gravel bikes. It\u2019s claimed to weigh a scant 179g.\u00a0<\/p>
$\"Integrated$
The rear light is diminutive in profile. – Oscar Huckle \/ Our Media<\/figcaption><\/figure>
Tucked behind the seatpost is a removable 20-lumen StVZO USB-chargeable rear light. The light fits snugly into its own recess and has a claimed 90-minute run time.\u00a0<\/p>
$\"Integrated$
The front end uses a separate bar and stem configuration. – Oscar Huckle \/ Our Media<\/figcaption><\/figure>
The front end integrates the bike\u2019s hydraulic hoses and Di2 wires. These run alongside the proprietary fork with flat steerer faces before passing through the upper headset bearing.\u00a0<\/p>
On this particular bike, you get the ICS 2 stem with an aluminium handlebar rather than the fancy ICS Carbon Evo integrated cockpit found on the Roadmachine 01 Two<\/a>.\u00a0<\/p>
A mid-tier spec for a high price\u00a0<\/h2>
$\"BMC$
This Roadmachine is second from the top in the range. – Oscar Huckle \/ Our Media<\/figcaption><\/figure>
The Roadmachine 01 AMP Two is one of four bikes in the Roadmachine 01 AMP range, retailing for a not-insubstantial \u20ac7,999 \/ $7,999.\u00a0<\/p>
The Roadmachine 01 AMP One above it will set you back \u20ac8,999 \/ $8,999 and steps up to a Shimano Ultegra Di2 R8170<\/a> groupset. A gravel-flavoured BMC Roadmachine 01 AMP X with SRAM Force AXS<\/a> has the same price.\u00a0<\/p>
Finally, there\u2019s the Roadmachine 01 AMP Three, which also retails for\u00a0 \u20ac7,999 \/ $7,999, but swaps to a Shimano 105 Di2 groupset<\/a>.\u00a0<\/p>
$\"Shimano$
You get a GRX Di2 groupset. – Oscar Huckle \/ Our Media<\/figcaption><\/figure>
The Roadmachine 01 AMP Two is specced with a Shimano GRX Di2 RX-815<\/a> groupset. BMC pairs a relatively wide-ranging 11-34t cassette with a Rotor eVegast 48\/31t crankset.\u00a0<\/p>
$\"Pirelli$
The Pirelli Cinturato Velo is a resilient tyre choice. – Oscar Huckle \/ Our Media<\/figcaption><\/figure>
The rolling stock comes in the form of BMC\u2019s own CRD-400 SL wheels. The 40mm-deep carbon rims sport an on-trend 23mm internal rim width<\/a>. BMC claims the front wheel weighs 710g and the rear 867g.\u00a0<\/p>
The Pirelli Cinturato Velo TLR tyres<\/a> are set up tubeless on the rims. These are all-year tyres in a 32mm width, so should be nice and comfortable on a variety of terrain.\u00a0<\/p>
$\"Fizik$
The Fizik Argo saddle is a popular choice on many endurance bikes. – Oscar Huckle \/ Our Media<\/figcaption><\/figure>
A Fizik Argo Tempo R5<\/a> saddle rounds off the build in a 150mm width.\u00a0<\/p> <\/body><\/html>\n
