New BMC Teammachine ebike rides like a regular bike, but my testing revealed it isn't flawless
BMC has unveiled the Teammachine 01 AMP, a new electric road bike that's designed to preserve the handling, stiffness and light weight of a conventional race bike. Built with a near-identical geometry to the Teammachine SLR 01, the Teammachine AMP 01 also uses BMCs 01 Premium carbon construction. To all intents and purposes, it looks like a non-electric road bike. I had the chance to try the bike in Italy before its launch, and was very impressed by the integration, natural ride feel and handling. That said, the motor integration doesn't always provide the seamless help I would hope for.

Road Bike Connection Spring - Mirror Media Speaking of the motor, assistance comes from the TQ HPR40 drive system, which delivers up to 200W output. As with other TQ systems, the motor is designed to be compact and quiet, with a focus on delivering smooth, natural-feeling support rather than high peak output. As a result, peak torque is capped at 40Nm. An internal 290Wh battery is said to offer up to 130km of range in eco mode, assuming an 80kg rider and average riding conditions. I was around 87kg for my test ride, and rode it up some steep hills measuring well into the teens so I could reasonably expect less. Theres the option to add a 160Wh range extender for longer rides, albeit this uses up one of the bottle cages. The top tube houses a TQ display unit. Road Bike Connection Spring - Mirror Media BMC says the system is engineered to eliminate motor drag when you pass the UK and European limit of 25km/h, which in theory offers friction-free riding at those speeds, as well as when the motor is switched off. On the basis of my short 25km test ride, thats an accurate assessment. I couldnt discern a difference between the Teammachine 01 AMP and a non-electric Teammachine with the motor disengaged or switched off. With the motor on, its a slightly different story. In the low setting, the motor is acting on the drivetrain, but its also introducing noticeable friction as you also push against the motor. BMC has strived to keep to the core design of the Teammachine SLR. Road Bike Connection Spring - Mirror Media In short, in this mode the power delivery was capped at such a low level that when I pushed hard to accelerate, I found the system felt draggier than it would have done with the system switched off. Its also noticeable (to a lesser extent) in the medium setting, meaning only the more powerful two settings are really powerful enough to feel like true assistance when you're working hard. BMCs on-site engineer explained the TQ motor can be adjusted to deliver different torque settings to mitigate this, and that the motor is designed to complement the riders efforts, rather than dominate them. The rear light mounts onto the seatpost, and is powered by the central battery. Road Bike Connection Spring - Mirror Media On the one hand, I can see how a rider might opt to use the motor only when needed full power for the steep climbs, and simply have it switched off for the rest of the time, when the extra couple of kilos are practically unnoticeable. However, based on my first ride of the Teammachine 01 AMP and its TQ motor system, I think there are still improvements to be made when integrating pedal-assistance tech into road bikes if the goal is for the motor to be completely unnoticeable or a help to the rider. Race-bike stiffness and compliance The frame's tubes are near identical to the Teammachine SLR's. Road Bike Connection Spring - Mirror Media That said, theres plenty to like when it comes to ride feel. BMC says the Teammachine 01 AMP matches the stiffness levels of the Teammachine SLR 01, thanks to its use of the brands 01 Premium carbon layup. Like the regular Teammachine, the ebike also adopts the brands Tuned Compliance Concept layout essentially, dropped seatstays, which help with compliance. It also has capacity for 34mm-wide tyres. There are aerodynamic features carried over from the Teammachine SLR 01, including an AeroShape seatpost, truncated tube profiles and AeroCore bottle cages. Up front, the ICS Carbon Evo one-piece cockpit integrates the cables and is designed to increase front-end stiffness while reducing drag. The down tube sports the 290Wh battery. Ultimately, I can spot a small amount of extra down-tube capacity built to accommodate the battery, while the mid-mounted motor is housed in an expanded bottom bracket shell (not dissimilar to the modifications built into the Teammachine mule bikes used to help develop the erstwhile Mavic X-Tend motor system). Theres also a TQ head unit integrated into the top tube, but everything else is normal. However, it all makes for an ebike that feels every inch a regular road bike when you have the motor switched off. That's helped by the fact that the AMP is based on BMCs Pro Race geometry, shared with the Teammachine SLR the same reach figures, but paired with an additional 20mm of stack (which is no bad thing for most of us). Models and prices The Teammachine 01 AMP is available in three builds: the Teammachine 01 AMP ONE, fitted with a Shimano Dura-Ace Di2 R9200 groupset, costs 13,499 / $13,499. This is underpinned by the AMP TWO with an Ultegra R8100 drivetrain (9,499 / $9,499), and the AMP THREE featuring a 105 Di2 R7100 groupset at 7,999 / $7,999.
