REX E-MTB's – the right drive for your needs



With more than a century-old tradition making bicycles, we are pleased to partner with AEG, a brand with an equally long tradition, to bring e-bike motors onto the market. 


AEG has been building electric motors for a wide range of applications for decades and has built a reputation for itself with many products, from drills to rail locomotives. We are now collaborating to develop high-quality e-bikes with a unique design and future-proof engine technology.

The powerful 48 V mid-mounted engine with downtube battery makes every mountain conquerable, even under a heavy load. The mid-mounted motor delivers consistently optimal support thanks to a sensor to measure your pedalling cadence and speed. You also have your choice of five coordinated levels of assist.

The exclusive ProKey chip technology provides clever protection for your e-bike. It's needed to turn on the e-bike and, in conjunction with the proLock, to unlock the frame lock. It also functions as an electronic immobiliser to ensure protection against theft.
