Has anyone heard of Mozzi bikes? Their website is www.mozzi-bikes.com They are in Chesterfield apparently, and have a small range of e-bikes in the price range £600-1000. The specs look quite good, they use bafang motors. I could find no reviews, and more or less no trace through google...

[ATTACH]5035.vB[/ATTACH][ATTACH]5036.vB[/ATTACH][ATTACH]5037.vB[/ATTACH] Hi, Here are the images. Yes John, I did buy it from you, I'll give you a call tomorrow. I don't think there is anything wrong with the battery as such. Maybe it doesn't fit as well in the older frame? The plastic underneath the connectors on the bike seems damaged, and the meeting parts on the battery, Thanks

Hello again, I have been persevering with aluminium foil, but this problem is getting worse. It is now obvious that overheating of one contact is deforming the plastic surround on the battery, and damage now extends to the the area around the battery socket on the bike. Sorry, I have pictures, but I have failed to upload them today. Also I took the battery off yesterday and again it was stuck, on removal it was apparent that the aluminium foil had melted. I did try to lever in the contacts as flecc suggested by putting something behind the metal contacts on the battery, but this failed to make a good contact - hence the Al foil. I am reluctant to use the bike in this state, but don't see how this can be easily resolved, any further thoughts??

Apologies for using an old thread. My problem is with the ezee battery gauge, as shown in the picture above. I bought a replacement one (from John - above) for my Ezee Quando. I wired it as the old one had been wired (which is as above). From the start I only got a green light - regardless of the state of the battery. I thought my soldering migth have been dodgy, so I just ignored it as the bike worked fine. Anyway I opened it up recently and remade all the solder connections. I am fairly sure my soldering is OK, but this fault still persists. I looked in the technical manual mentioned above and note that not all the Ezee bikes seem to be wired the same way in the gauge. Might this gauge be different from the original, or what could explain always getting a green light?

[ATTACH]4627.vB[/ATTACH][ATTACH]4628.vB[/ATTACH] Thanks for the suggestions. I followed flecc's advice and had another go cleaning and prising the contacts out a bit. I noticed one was harder than the other to move. Anyway this didn't work, the light came on for a fraction of a second and that was it. I was preparing to try the vaseline thing, but then decided to put a bit of aluminium foil into the contacts on the battery and this worked. I then figured out that it was only the rear connector causing a problem - i.e. it will work with no foil in the front connector. Note I said the rear connector looks a bit out of shape. On closer inspection I can see some of the surrounding plastic has actually melted a bit - I attach 2 photos. The metal contact was actually stuck to the plastic on one side. I am concerned to know how this has happened, the battery was bought in April. So, I guess I can use the bike with a scrap of aluminium foil, but how reliable would that be and might this happen again? Also the battery is under warranty, could this have been caused by water, should I send it back? Thanks in advance.

Hi , I have a 2006 Ezee Quando. In April this year I took he plunge and replaced the NiCd battery with the new type Li ion battery. It has been great, but I have had increasing problems over the last 2 months, and am now off the road. I don't think there is anything wrong with the battery itself, but there is a problem with the connection. Sometimes (now pretty much all the time) the battery does not seem to register - the light by the key switch goes off as does the light on the display on the handlebars. Initially this was an occasional and intermittent thing and I found that if I just 're-sited' the battery or just wiggled it a bit the lights and power came back. When this became worse, it seemed that the battery was not quite siting in the right place, and I just put a small piece of plastic inside the mount so it held the battery a bit tighter and higher. This little bit of play does seem to right the problem, sort of, but it is now worse so I can rarely get contact. I have had to store the bike outside sometimes, and it has got quite wet. However the timing of the deterioration is with a drier spell of weather - and the day I finally gave up it had not rained for the previous few days. I have kept the bike in for the last few weeks by a radiator in an attempt to dry it out. I have opened the display box on the handlebars, and checked connections. I have also had a peak in the box by the motor, and looked at connections around the key switch and all seems in order. I have tried to clean the contacts, and there was some black stuff on the contacts. The battery is charged and consistently reads 36 V. I notice the rear connection port on the battery does seem slightly pushed out of shape, Any thoughts appreciated

OK, thanks very much for the advice. And that's mighty fast for a Friday afternoon..

Despite this thread being old, it is relevant to me. I have been riding around on an Ezee Quando 2-3 times (about 20 miles) a week except in midwinter, since 2006. Initially the battery took me (laden down) about 16 miles. About 2 years ago this dropped to about 10 or 11, about a year ago about 8 miles. Now I struggle to do a 7 mile round trip, with frequent cutting out on hills, sometimes no response on a fresh charge. I find the Electric Transport Shop in Bristol offering a recell service. My bike is mechanically in order, and I have had to mess about with the electrics in the past, and am sure the problem is only the battery. It is a 36V NiMH 10Ah battery, and they recell with lithium polymer, involving purchase of a new charger. I understand these batteries are better, and it is considerably lighter (total outlay - £445). Does anyone have any experience with this company, or having this type of recell procedure carried out. I want a few more years service..
