First remove the battery then find someway to support the bike as removing the rear wheel also removes the stand...
Remove the 2 Philips head screws securing the rear mudguard and the 2 on the LHS rear axle cable protection cover & slide the cover off. Disconnect the rear brake. undo the rear axle nuts. Loosen the chain adjusters and slip the chain off. You may also have to deflate the tyre to get it past the mudguard.
I have a GIANT LA FREE SPORT ELECTRIC BIKE. THE
The brake handles have each have a switch button that must be pressed for the motor to work. (Actually what happens is that when you pull the break lever it unpresses the button so the motor won't work against the brakes). Just tape the switch down for the time being. Electric Bikes Northwest and David Hawkins might be able to help you with bike parts. I've gotten some parts from him for my La Free Sport. Very few bike shops know anything about these bikes.
Good Luck!

How do I diagnose my aprillia city enjoy that the motor doesn't work anymore
You can download the workshop manual from a few websites, including this one
APRILIA Enjoy City Workshop Manual
I would start by checking and cleaning the battery contacts where they connect the battery to the frame wiring harness near the seat post. The controller requires both 24V and 12V to activate the motor. If the battery gauge is indicating a full battery then it may be that the controller is not getting the 12V feed.
I had to replace the controller in my Aprilia because it had a fault. There is a lot of information on the Aprilia Enjoy models here.

Sakura S305 electric bike, no speed control
I'm not familiar with that make/model, but if it has a brushed motor then it is likely that you have a faulty controller module. Most brushed motors have just 2 wires running to them from the controller.
Scooter bikes
Most motors are housed in the wheel hub. Just look to see where the wiring is going.

That is an unusual value. You could try a 25 amp fuse instead as this is a more common value. RS Components or other electronics parts sellers should have them.
Electric bike cuts out while riding
Couple possibilites. If it is just a matter of your battery clips coming undone, tighten the with pair of pliers then reattach. If it cuts out, then reengages when you start pedaling, either your controler is shot, or you have a ground short on your wheel hub. How long does a charge hold, and how often does it cut out?
