REVIEW: QR-E 250W ELECTRIC BOOSTER BICYCLE MOTOR AND B60i AND B70 BATTERY

how do I translate thi
I wonder how this friction drive unit performs. Couple good reviews on Amazon and one on a Redit forum that I could find. Relatively inexpensive, uses standard 48v battery, retracts from wheel, bidirectional capable, claimed 350w which is more than the Qiroll Pro.

This looks interesting. Having an electronically retractable motor is a big plus, the system I tried 30 years ago had one and really liked it. Wonder how much it weights? I'm really tempted

I saw the setup, looks bigger and bulky than Qiroll. If they make it compact and smaller i might pick one up and mix with my hailong/bafang battery pack.

They list weight as 1.5kg, not sure if that includes the control.
 
Google translate. It'll even translate text in images which is amazing.

I'd be interested in the Pro too but I'm not going to spend over $500 just to find out if it would be adequate for my use or not. I ordered something else instead and when I recieve and install it I'll post up my experience, good or bad, it'll probably take a few weeks.

Byłbym zainteresowany również wersją Pro, ale nie zamierzam wydawać ponad 500 dolarów, żeby się przekonać, czy będzie odpowiednia do mojego użytku. Zamiast tego zamówiłem coś innego i kiedy ją otrzymam i zainstaluję, zamieszczę swoje wrażenia, dobre lub złe, prawdopodobnie zajmie to kilka tygodni.
To co zostało zamówione pochwal się😃
