Hi strange because I got this reply from autoclub2015 on eBayIt's a 5 minute job to swap from one polarity to the other.
Hi & welcome to the forum.I have a Cyclomatic 12v 10ah electric bike which needs a new battery there are so many out there but finding the right size with the polarity on the right side is proving very difficult can anyone help ?
Hi D8veh,To change the battery, it's 4 screws to get the bottom off, two more screws inside the bottom piece to get at the terminals, swap them over, reassemble 6 screws. I'll bet anybody that I can do it in 5 minutes.
To be honest I'm completely confused I have been told I can increase the ah to say 15 but the 24v has to stay the same unless I change the motor is changed have seen some YouTube vids on 48v Cyclomatics which are great but really all I want to do is replace my battery which is dying to another maybe a bit stronger battery. The other problem I have is that the bike is in Lanzarote and bringing batteries over here is not easy with a lot of airlinesMotors don't care about voltage. You can run them on 100v and they won't blow, though the Cyclamatic would be very inefficient at 100v. Have a look for Youtube videos of 48v Cyclamatics.
I've been running a cyclamatic power plus at 36v for several months & several hundred miles, using a stock controller, with no problems at all.So even though I have a 24v 10ah battery I could upgrade to a 36v ? I thought this may blow the motor
Hi.Hi mw1
Thanks for your reply is your bike the one with the silver fish seat post battery and was the original battery 24v 10 ah ? If so it sounds promising also if possible could you let me have the link to where you bought it much obliged Rob
Yes it was a direct fit, though always check the polarity 1st, as explained earlier in this thread.Thanks Mark
Strange I tried this seller and the reply I got was
Hello,
Thanks for your attention.
I'm sorry we don't have the case with 24v 10a battery,
This battery is 36v, it can not be used for your motor, it will be burned.
Best regards,
Also did it fit straight on without changing the post etc and is the performance any better
Thanks Rob
No problem Rob. I have about 2 & a half years experience with these bikes, and am more than willing to help whenever I canThanks Mark, I have checked the polarity and it's ok. Will give this a go maybe ask you in future about modding !! Thanks for all your help
Rob
You were told wrong!I have been told I can increase the ah to say 15 but the 24v has to stay the same unless I change the motor
Hi MarkNo problem Rob. I have about 2 & a half years experience with these bikes, and am more than willing to help whenever I can

Not very likely unless something is obviously wrong with it. Mechanical noise, juddering and jamming is often caused by the controller or bad connection.we think the motor has gone in the back wheel
