I USE MY ELECTRIC BICYCLE AS MY COMMUTER AND IT JUST BROKE. PLEASE HELP!!!!!?

Jimmy

I use this like it's my car. I just don't want too lose my job. I would so appropriate if you read this for me. And I have a kid :( Anyway I bought this off Amazon. It was $250 it's a 1000w 48v 10-30aph with a lithuim Ion battery that is 48v 15aph. I have driving it for about a month. I have driven it almost everyday. It goes about 22miles if you help it. So I drove it home today. I ran it full throttle. I usually do because I don't have to go super far. Anyway everything was fine worked perfect. I had to go back to work later. I hooked it up to the charger and took a three hour nap. I woke it was charged. I took it outside to go to work. I turned it on. Nothing all it did was jolt. Like a quit surge of energy and then gone. It last a little less then half a second and it's a weak jolt. Also it tries to go backwards too. All the plugs and cables are fine. Used my neighbors multimeter. I was wondering if it is the motor or speed controller. I'm a pretty mechanical included person so any info would be nice thank you for you time.

Answer
At first my best guess was that you may have overstressed the battery and its now paperweight. Measure the voltagetoday and tomorrow and see if it falls dramatically.

However "Also it tries to go backwards too." sounds like it could be the controller.

Can you connect the motor directly to the battery to test both without the controller? Or test the motor by connecting a 12V battery or charger?

If you arent happy doing this a bicycle or appliance repair shop may help

can I replace my 6v 4.5ah battery with 6v 12ah battery?

Cool PR

My son has an electric power wheel car that I bought from EBay. it comes with a 6 volt 4.5 ah battery, but seems to run weak on slight up hill side walk. I also have a Speed racer 6v car which runs fine. Would a 6v 12ah battery help or just extend the joy ride. How about a slight increase in amps like 8Ah or will that burn the motor? Any ideas will help. Here is what it looks like http://cgi.ebay.com/RC-Remote-Control-Ride-On-Power-Wheels-Mini-Kid-Car_W0QQitemZ360157224808QQcmdZViewItemQQptZRadio_Control_Vehicles?hash=item53db0b1f68&_trksid=p3286.c0.m14&_trkparms=72:1205|66:2|65:12|39:1|240:1318|301:1|293:1|294:50

Answer
As long as the voltage is the same, it should be safe to run the higher ah battery. The higher amphour rating will last longer between charges. The same as replacing a 12v 400 ah battery in a car with a 12v 800 ah battery. Just make sure it will physically fit.
