I have just ordered an e-bike, it is a Jasion Hunter Pro. It is a folding ebike with a non-standard style tube frame. I am unsure if a U lock will be appropriate. Does anyone have experience with these models of folding bikes.

Should I consider a U-lock or a chain style lock.

If chain style, what length do you reccomend?

I live in Philadelphia, and the rate of bike theft here is insane. Im open to model reccomendations, it possibly will need to be able to survive from 7pm-3am outside if my job doesnt allow me to bring it in the building. I plan on parking it on a local community College campus with surveillance, getting cable locks for the wheels, putting locktite blue on each nut and bolt, and supergluing metal pellets into Allen key hole (they'll even steal your seat if theyre able). I will also be hiding a GPS unit within the frame. I have pretty throuroughly thought through the best ways to protect it, I am simply just stumped when it comes to my primary locking mechanism and the best way to secure the bike itself.
