The competition and ebike mid-motor WARS are heating up between BOSCH, BROSE, YAMAHA, POLINI AND CONTI MOTOR.
We are happy to announce the one new mid-motor motor system from TTIUM. With 95 Nm and 45 km/h speed, their mid-motor performance is at the same level as above mentioned motors. We don’t know the price yet
As a high-tech innovative enterprise, Wuhan TTIUM Motor Technology Co., Ltd. is focusing on R&D and manufacture of Pedelec’s intelligent driving system. TTIUM motor’s mission is to develop and improve a world class Pedelec drive system, to provide users with ultimate riding experience.
Their development lasted 2 years
This is what they came up with ( video on bottom )

2 years of effort and they “came up” with a tiny little motor that’s light years behind everyone else. Why didn’t they just buy something off the clearance rack at some other bike motor company. My bike is over a year old and it has a 52V 1500W motor on it. And it cost l3ss than $1500. Are these guys even trying?
