Avinox has revealed its new MG Concept at Eurobike, with the motor incorporating an e-CVT-style gearbox into the assembly. The new MG Concept takes power from Avinoxs M2S motor, which delivers up to 150Nm of torque and 1,500W of peak power. It appears to be far down the production line, with the brand displaying it on Forbidden, Mondraker, Commencal and Canyon frames. Avinox says the motor is its first with regenerative braking, meaning the bike will recharge on descents or when braking. Ferdinand Wolf, Avinox product experience director, says in the official press release: Avinox continues to challenge what is considered possible, and we are privileged to work with the best in the business. OEMs and consumers alike are embracing the Avinox ethos and vision, and we are dedicated to delivering on our promise of bringing them the best cycling experience imaginable. Avinox is taking over here are 20 bikes you can buy with its incredible new M2 and M2S motors While riders have been asking for something like this for years, the MG Concept could signal the beginning of the end for the derailleur on high-end electric mountain bikes, putting serious pressure on SRAM and Shimano. The packaging for the unit is very compact and doesn't take up as much space as Pinion's design. Nick Clark / Our Media Avinox says the MG Concept is fully customisable, with the device offering configurable gear profiles over a range of 100% to 520%. A Forbidden prototype appeared on the Avinox stand at Eurobike. Nick Clark / Our Media There is also an automatic mode, which can be set to maintain a cadence or power input, although you can also shift manually as you would in a car. The brand claims the system is three times more durable than a traditional drivetrain and requires less maintenance. It also says it has found traditional drivetrains to be 10% less efficient than its system. Commencal also appears to be an early adopter of the tech. Nick Clark / Our Media The device also enables you to lock the motor mechanically, making it more difficult to steal because the cranks wont spin. Another unusual feature is the electric reverse assist, which the brand didnt detail, but we assume its for moving the bike at slow speed rather than for boosted fakies. Avinox says it is still working on chain tensioners and has yet to decide if this is something bike brands will be responsible for. Nick Clark / Our Media The MG Concept appears to be compatible with a chain drive or belt system from Gates. Mondraker's prototype featured a belt drive. Nick Clark / Our Media The device is one of several e-CVT bike motors we've seen at Eurobike 2026, including one from Avinox challenger Gobao. Canyon displayed the tech on its M214 prototype enduro bike. Nick Clark / Our Media
