Hi folks this is my first post on this thread.
I have acquired a non working City version of this bike.
There was no battery at all. Just a big open space between the side fairings where it would go, and the little hinged flap that should be just in front of the seat post was broken off. Otherwise the bike is in pretty good shape.
I had some Samsung 18650 26f cells from laptop batteries, left over from a previous rear wheel direct drive ebay kit project, and made up a 6s battery with a 12v voltage regulator hooked up to feed the pedelec etc so that I could test the original system, but nothing was working. The motor worked fine though with a direct feed to it.
Next I followed advice from this thread, and got a cheap 24v 500w controller off eBay. I already had a throttle & ebrakes.I've now got an 8s4p battery made up from my 18650's, Velcro tied to the battery copartment baseplate, with the controller where the original one was, gear shifter on the left side, twist throttle on the right & ebrakes replaced with the ones I had. I have a wattmeter wired in so that I can keep an eye on my battery usage, and balance leads wired in so that I can use battery alarms when they are getting a bit low.
I've been testing it for a few weeks now, & it all seems to work well. I need to go a bit steady, as the battery setup I'm using, is only rated for about 20amp discharge, but the controller can pull closer to 30 amps at full throttle.
Performance & range is very similar to my hub drive bike, which is using the same cells in a 10s4p arrangement, so I'm doing about the same thing with using 8 less cells.
One ride I like to do is a 32km round trip & includes a big long hill, which is a walk up for me on a normal bike.
I can do that trip, & ride the hill on a fully charged battery. I add a bit with the pedals, but nothing very strenuous.
Now that it's all working satisfactorily. I want to tidy the whole bike up & get it looking nice. To do that I need a battery lid & handle, & also the little hinged flap that would go over the original charging port.
Does any of you here in Oz have those parts spare, that I could buy, or can you let me know where my best bet is for buying them new?
My other option would be to make something up to close the top of my battery box out of fiberglass, but that would be a fair bit of work to do.
Hope someone can help me out, & thanks anyway for all sharing your experience with these great bikes, and making it a breeze for me to have got mine going well.
