BMC has announced the Roadmachine 01 AMP X, its first electric bike<\/a> to tread the line between road and gravel.<\/p>\n

The brand says TQ\u2019s lightweight motor contributes to the top-of-the-range model\u2019s claimed weight of 12.9kg.<\/p>\n

Meanwhile, the Roadmachine AMP X offers wider tyre clearance and more endurance-focused geometry than the existing BMC Roadmachine AMP<\/a>.<\/p>\n

The all-road bike<\/a> is only compatible with electronic groupsets<\/a>. The two Roadmachine 01 AMP X models come with 1x XPLR drivetrains<\/a> from SRAM, geared towards off-road riding.<\/p>\n

You can buy the SRAM Force eTap-equipped BMC Roadmachine 01 AMP X One for \u20ac8,499 \/ $8,899.<\/p>\n

The Roadmachine 01 AMP X Two, specced with SRAM\u2019s mid-range Rival eTap AXS components, is available to buy now for \u20ac7,499 and from December for $7,899 in the US.<\/p>\n

The BMC Roadmachine 01 AMP X is powered by the TQ HPR50 drive unit. It first appeared on the Trek Fuel EXe<\/a> electric mountain bike and, subsequently, the Trek Domane+ SLR<\/a>, which offers clearance for 40mm tyres and focuses on lightweight drop-bar versatility.<\/p>\n

The Domane+ and BMC Roadmachine 01 AMP X look to be close competitors in an evolving category that blurs the lines between e-road and dedicated electric gravel bikes<\/a>.<\/p>\n

TQ claims the mid-drive electric bike motor<\/a> is the lightest in its class at 3.9kg. It offers a 360Wh battery, and maximum power and torque figures of 300W and 50Nm respectively.<\/p>\n

In accordance with electric bike laws<\/a>, the motor offers assistance up to 45km\/h in the US and 25km\/h elsewhere.<\/p>\n

More frame integration and less aggressive geometry<\/h2>\n

The BMC Roadmachine 01 AMP X\u2019s carbon D-shaped seatpost has an integrated rear light, which connects to and charges from the battery.<\/p>\n

In addition, a bike computer<\/a> and front light<\/a> mount is built into the handlebar, while the drive unit display fits into the top tube.<\/p>\n

Mounts for mudguards or fenders<\/a> tick off another feature common on many of the best endurance road bikes<\/a>, motor-assisted or not.<\/p>\n

BMC says the Roadmachine 01 AMP X\u2019s geometry is more relaxed than the original Roadmachine AMP.<\/p>\n

The taller stack height raises the front end of the bike for a more upright riding position, while shorter chainstays make the bike stiffer and more manoeuvrable, according to the brand.<\/p>\n
