If I ever convert my bike to electric, I'll probably go with this https://www.swytchbike.com/

I actually bought one of these and love it. My road bike is indistinguishable from any other normal road bike with the exception of it being much easier to get around now.

From experience I can say that it seems like a lot more common sense to simply replace the front wheel of your bike with a wheel containing an electric motor, rather than attaching whatever Asus is selling to your bike.

Do you feel the power is sufficient? It says it's only a 250 W motor. What is the battery range?
