Hi Kim .. Yes as Paul has mentioned they should be able to test your battery to see if it has died. If it hasen't then they will be able to check your charger too. If they are both ok then it might be your controller or maybe it is just a blown fuse?

Cheers Mike

Hi Kim,
Try 'Battery World'. They should not only be able to diagnose the problem but also offer a solution.

Cheers,

Paul

I love my electric bike (bought from the Ecoshop in West End last year) until two weeks ago, the charging stopped working. I do not really know if it's the charger's fault or the battery's fault. Ecoshop is closed down now and I do not have any where to contact. is there a place that you can recommend me for help? Thanks so much. Kim

Hi Tony - Yes the electric current is cut off when you apply the brake. In both the front and rear brake levers there is a small switch which is wired into the controller. Whenever you apply/pull one of the brake levers it triggers the switch which sets off a relay which stops any current from getting to the motor.

The slight delay you mention from when you stop pedaling is only if you don't apply the brakes. If you do apply the brakes there is no delay.

Cheers Mike

Hi Mike,  Thanks for the look over and test ride of your bike on the weekend. It was great, have a quick question tho either yourself or Sapoty could answer.  Does the electric motor cut out when you grab the brake?  Say in an emergency for instance. You may remember I commented that there is a a slight delay when you stop pedalling which is expected when you consider it takes a half cycle before the motor starts up.

Cheers Tony.

Hi Sapoty - You are right . . The battery is much lighter than I thought. Definitly no more than 5 kilos. My bad.

Yes I have mounted the GPS case on my handlebar and I am running an ipaq 212 PDA which can do just about everything except be a phone. It runs on Windows Mobile 6. i have got about 12 different sat nav programs on it including TomTom, Garmin, Igo etc.

However for a bike the only really usefull one is GPS Tuner because you can use your own maps and it works off road as well as on road.

I believe you can get GPS Tuner for an Android phone. I googled it and the Android version looks really good.

Cheers Mike

Mike, if you are talking about your beyond-oil bike with a 36 V 10 Ah LiPo [lithium polymer] battery; the battery weighs 4 or 5 kg. Is the GPS case on your handlebar? I have an Android phone ... any suggestions for an app?

Just a couple of clarifications to my post below ... I have since found that my ride to work is not 17k's but is actually 21.3k's (42.6 Round Trip). I have just started to use GPS Tuner on my PDA which is attached to my handlebar with a new waterproof case. It has confirmed that I actually ride further than I thought.

Also the E-bike is not 35kg's in weight it is 25kg's. Of that the battery weighs about 10kg's.

Cheers Mike

Good to hear you have sorted out the disc brake adjustment Mike. It took me a while to get the hang of them too. Earlier on I had a few warped discs come through on bikes, but I alerted the factory to that and have not had that problem for a while.

It is a labor of love selling ebikes because the market very price competitive and so the margins are low. But it is nice to know I am doing some good for the environment by helping reduce car usage to some extent.

Hi Sapoty .. Good to see you joined up on the site. There is lots if interesting items on this forum and a very friendly bunch of people on here too.

Regarding my isues .. The chainguard does have an slide type of adjustment to allow the guard to move back or forwards, but I still needed to raise the chainguard upwards a little to stop the rubbing. It was easy to do, i just got a small piece of plastic and modified the mounting a little. No big deal really.

The Brakes have been a problem. I think I have finally figured out what the issue is though. It is to do with how far the inner brake pad is set away from the disc. If you don't have it at just the right distance from the disc there are 2 possible problems. Either it is too close and it rubs as you ride, which is annoying and noisy (Squeaks). Or it is too far from the disc and then when you pull on the brake lever the outer pad presses against the disc but has nothing behind the disc to assist with the grab. It then seems that the brakes are not working too well causing you to pull on the lever even harder. When you squeeze harder on the brake lever it can actually pull the cable out of the clamp down at the brake. This of course leave you with no brakes.

So it all has to do with how you adjust them in the first place. The last 3 days I have had no problems as I think i have got it sorted now. I will still fit some new cables when they arrive though as I have damaged them with all the messing about I have done. So the problems with the brakes has really been my fault in not setting them up correctly and not the brakes themselves.

Regards Mike
