I am not trying to argue. I am just trying to give you best advice even if it is not what you would like to hear. I know those bikes are easy to pedal. Fat bikes are designed to operate by throttle or in ghost pedal mode, but on seats like that you and your wife will have to keep legs wide open. Without seat height adjustment both will be uncomfortable to pedal in long term.
One more thing... 10Ah battery is not good enough on bike like that. You both will need high discharge 20Ah+ and pray you won't run out of juice far from home.
Thanks I am going to add a 20 or 25ah battery onto wife’s bike soon as I find a good one with decent cells at a good price I have already the same 30\40 ah splitter discharge balancer thats fitted to my Knapp for hers .

PSW have good and cheap batteries (just not the one you linked).
Greenlance is another good choice if you are looking for UK supplier.

That's a different one to the one shown in post #1, which is clearly prefixed EW, not RM.
yes thats my knaap my wifes one is in the shop being setup all gears needed work and some puncture proof tubes hers is a 250 qs the shop i use wont work on any bike thats not legal they only worked on hers as the throttle does not propel the bike it is non functional :) the bike is actually sold online as a a mario 250watt bike :) the guy i purchased it from has shown me the receipt of original purchase and price from online store and it only does 15.3 mph.

The police only check the markings on the motor. When it says 500w, you're out. The regulations say 250w motor, not 250w bike.

Is this it?

No, the motor doesn't care too much about voltage. The voltage affects the speed and efficiency. If you go too slow up hills, it would get hotter, but the higher voltage gives more torque, so it's easier to maintain a higher speed up the hills.

Before anything, check that the motor does indeed say 500w. There are some quite convincing 250w labels you can buy from Ebay to stick on your motor. Just saying, not suggesting.
