I've been riding e-bikes for over a year. I currently have two e-bikes by Momentum. A Transend E+ and a LaFree E+.

I have a problem with the Lafree that I hope someone on this site can help me with. I bought the bike as Demo, the dealer did not have a key for the battery and Giant/Momentum cannot provide one. I was told my only option was to drill the lock and then buy a new lock set. I have drilled the lock and can now remove the battery. However, I can't for the life of me figure out how to remove the old lock set and install the new one. Giant refuses to respond to my requests for assistance. Has anyone on this site gone through this and can provide some instructions on replacing the battery lock? Thanks for your help/

I would have taken it to a locksmith before I drilled the lock. They could have picked the lock and maybe made a key for it. You could still do that. It's possible they would have a lock cylinder that would fit. It looks like these bikes are a Giant product and the battery is still available. It is called an EnergyPak 400.

Thanks for your reply. As I said, I have drilled the old lock and am able to remove the battery. I have also purchased to new lock set like the one you posted. I just don't think the instructions are specific to my bike.

Never had the pleasure of seeing a Giant LaFree, but keys are either mounted in the frame or in the battery. If this is your lock and it's in the frame, you should be able to replace it if you drilled it. There's another view where it's held in by two vertical screws.

I bought my wife at the time a LA Free in 2004. It had a 24v NiMH battery, and was a mid drive drive with a 4 speed geared hub. Much better bike than I gave it credit for. Scrapped it because a new battery was unavailable (this before I started building batteries).
Wish I would of kept it.

Here's my battery. It is not in the frame but in the rear rack.

I'm just guessing, but the battery case probably needs to be opened up to get to the key cylinder from the backside to remove it.

There's probably some screws that hold the battery case together that can be accessed when the battery is removed from the carrier.

Sometimes they hide the screws under stickers or grommets or rubber/plastic plugs.

You might have a sealed battery that can't be opened, but I kinda doubt that.

Here's some pictures of my broken battery bracket for reference.

You can't access the screws until the battery is removed.
(So that anyone with a screwdriver can't walk off with your battery. )
