The hard drive is normally mounted in a metal (fariday)case. The local low frequency fields from the motor should have no effect on that.
It's an un nessisary scare story. Shock, drops and theifs are a more realistic risk.

Other related units are the skilodge (1 mb, or 10−31 m2), the outhouse (1 μb, or 10−34 m2), and the shed (10−24 b (1 yb), or 10−52 m2), although these are rarely used in practice.[7]
Not quite metric although given in metric units !
Cwah has his super speed bike for sale but where are you as international transport can be very difficult with lithium batteries?
A kit from China may workout the easiest option with delivery!
Welcome Wan.
Cwah has one of his bikes up for sale. It's a bit of a over powerful beast.
How much do you want to spend and how much can you spend?

Lycra or SPD,s or jeans and shopping basket?
Throttle or T sensor?
Yes I went with a nominal 36v 10 amp or 360watt setup.
The good torque sensor systems measure your input and then add a % depending on the controller of between 30 and 300% of your effort. Capped by speed and max power limits. So for every 100 watt you put in the back wheel will get between 130...
It's not truly representative to ask what the zongda is using as peddal effort and bike setup all affect the watts per mile.
With a well setup torque sensor system you tend to get higher miles per watt. Even 8 watt per mile is possible. But a throttle powered system running at 20 mph will use 20...
Personally I have had one cheap hub drive and two good crank drive systems. My wife has a good hub drive.
It's not just the drive that counts but as a cyclist having torque sensor makes the whole system feel like bionic legs.
My cd,s had three power levels 20 years younger, 20 years old and...
