Hey everyone! I just picked up a slightly used Killowat bike ebike. from what i can determine it's a 2009 killowatbikes cruiser. Overall its in good condition, however the removable battery pack and key are missing. I am wondering if i can purchase a battery pack that would fit the prong connection or if there would be a suitable replacement? it seems like the wiring shouldn't be too complicated - so would just finding a similarily shaped battery pack be a better option? The motor setup on this bike is a Bionx i believe.
2009 Kilowattbikes cruiser - what battery does it take? are there any good substitutes?

That's a pretty strong accusation!
I've seen plenty of used bikes where the battery has gone bad then been set aside and years later can't be found, same with the key and charger. I've even seen bikes that people still had the original purchase receipt but some how lost a battery, and/or key,and/or charger.
Where did you see it mentioned that the charger was also missing?
Doubtful unfortunately.
You could try searching for batteries with the same connection interface. If you could take a better picture of that connector I could try and search.
There are a lot of batteries you can purchase that come with the battery mounting plate, the trouble you're facing is that the rack appears to be welded and so you'll need to do some careful measuring to make sure the replacement pack will fit the available space.
You could also cut the top part of the rack off, giving you more space, thus more options or leave the rack as is and see if there's enough space in the frame for something like a "shark pack"
it wasn't stolen. I purchased it from a thrift store. someone donated it. i purchased it with the parts missing, etc. The rack is all welded to the frame. Are most batteries a simple positive and negative running out of it? from my searching, that appears to be the case. I'll get a better picture of the plug interface this evening.

From that era, yes. But there's a good chance that the front part of that battery rack has a space and that is where the controller sits.
I'm not sure if the picture I posted is your model but if you look at that picture it appears to be at least 3 wires coming down from the rack.
Yeah, that bike you posted looks like the ladies version of the kilowatt cruiser. Sounds like i need to pull the controller from the mount and get a better idea of the measurements and wire setup. I found some 36v batteries on amazon that look like they may work.
The battery area measures around 17" long, 2.25" tall and about 5.25" wide. Ive also added in pictures of the connector.

You need to know the voltage and figure out the polarity.
Kilowattbikes.com is still around. You could contact them and see if anyone remembers your model.
Probably 24 or 36 volts, if sold 10 years ago. I'd test the bike first before I spent money on a battery.
Looking at PDXzap's picture, there must be a motor in the front wheel? And a throttle on the handlebars? That box you show in your pictures must hold the controller. Does one cable goes to motor? Another to the handlebar controls.

Yes, motor on the front wheel. Ive tried to get ahold of kilowattbikes with no luck. I suspect they went from being US owned to a Chinese distributor or something. I think the box is the controller, wired as you suggest. What should i test on the bike? Mechanically its in good condition. Is there a way to test the motor and controller without a battery installed?

Pretty sure Kilowattbikes.com is just a generic site now as the first picture is of a Ancheer.
I don't think I've ever seen a battery connector quite like that. Searching kilowatt ebike brought up a few findings pointing to kilowatt possibly using an Bionx system but... ?

Have you looked inside the box?
Nope, not yet. Thatll be next step, to figure out what voltage of battery i need.
So my controller is a Ananda 2414DLL-3LAU00. Looks like a 25v controller although ive found some posts of people overvolting it successfully. I was thinking of just getting a 36v battery and wiring it into the controller and bypassing the security switch or taking it to a locksmith to see if they can make me a key... although i may do that after i verify that things all work first.
