Building on the ultra-quiet, ultra-small TQ 50Nm motors used on their recent Fourstroke AMP LT mountain bike , BMC is giving their endurance Roadmachine the AMP’d treatment, too.

It uses a premium carbon fiber frame and fork with their ICS MTT suspension stem and integrated cockpit, plus wide tire clearance, to create a capable all-road bike with a bit of assist. And for U.S. riders, they’ve boosted output to deliver Class 3 assistance up to 28mph! The Class 1 global version assists up to 25km/h, both using the TQ HPR50 drive system at the bottom bracket. As on the mountain bikes, it’s virtually silent, and barely visible. The 360Wh battery in the downtube and a 2″ display complete the system, which in total adds just 3.9kg (8lb 10oz) to the bike.

The display is nested into the top tube, showing mode, battery life, and a few other basic metrics that you can cycle through. For more data, mount your GPS cycling computer using the integrated stem-mount option, which can also hold a headlight.

Power delivery is smooth and natural, too. Combined with the lack of motor noise, they say it provides the most normal road bike-like experience possible. And if you didn’t know it was an e-bike, it’d be hard to tell from the looks.

Yes, that looks like a front derailleur mount, but the bikes will come only with 1x drivetrains using Rotor eVegast cranks with SRAM X-Sync chainrings. BMC says, at this time, they can’t comment about 2x compatibility or options.
