Answer
hi, i recommend buy a electric bike conversion kits to convert it . But please note some notes,
1. Does the motor fit for your bike ? I mean that you need to measure your bike drop out , and confirm it with the seller .
2. Confirm the right wheel size with your seller . You can confirm your bike wheel size according to your bike tires , such 26 x .... , 700c x ... It means your bike is 26inch, or your bike wheel is 700c .
3. The speed 70kph is very fast, so you need to make sure that your bike frame is good enough .
I recommend that the 1500w hub motor for your bike . Its speed is about 70kph with 26inch wheel, and the controller max current is about 40 amp .

Does anybody know of a cool electric vehicle conversion kit?

I don't have any particular make or model of vehicle in mind. I would like to purchase and then convert a vehicle to electric drive.
Ken, sounds like you have too much time on your hands too. ;D

Answer
You should start with a bike and work your way up.
