i also have a problem with my mx500, i had it for a year and it eventually stopped working, i mean it only went for 20 feet then it was dead out of battery. i then replaced the batteries and charged it up, well same problem so i then replaced the ESC and it didnt help either. i used my circuit tester and everythings proper except that only 21 volts is coming from the batteries the charger says they are full, I NEEd HELP.
First, look AFTER charging and without power on batteries voltage. You must have more than number batteries * 12V.
If not your charger doesn't work correctly (thats means your charging time must be very short too)
Second (if first case OK) it's probably your motor thats is out: it can turn but comes very hot in a very short time because cupper short circuits.

i need help with my mx500, i had it for about a year and i drive it on a woods trail. after a year the bike was extremely slugish even on the road and it took about 10 minutes to fully charge from the batteries being worn out. so i replaced the batteries, it helped a tiny bit so i replaced the ESC, it still did nothing. i have been riding it on the road and it is slowly getting better but still very short run times. like 5-10 minutes. i was wondering what the problem might be.
I'm Nathan and I'm 11 I am about to buy a mx500 and upgrade it to a mx750 I was wondering where the nearest tnc scooters is in barrington 60010 and just incase I decide to get the mx1200 how much is welding and where can you do it?
I know it's been a while but yes, I have continued to modify my 2-MX 60 Volt 1,000 Watt Razr Dirt Bikes!
I am still waiting for my motors to arrive but I still have been working on them once in a while.
I welded 6" front fork extensions on the front ends of my Dirt Bikes down where the brake calipers are located. I did that because I added even longer and larger 12" rear shocks that raised the back end up to high. My bikes stand up as high as full size motocross bikes now! Now I will be able to jump a lot bigger jumps without bottoming out!
I also added an additional 5 more amp hours to my previous 12 amp hours bringing me to 17 amp hours of ridding time!
I have also murdered out my dirt bike rims to Gloss Black for a more aggressive look with Dupont Paint!
I will post my updated photo's when I get my motors in, hopefully within the next month!!!
I am going to mod my MX650 too. I found all the stuff but what will give me the most power for dirt and grass? I want speed but more power so i could go as fast as i could on grass than i could on the street. Is that possible? Is it the 48 volts that do it or is it the motor, i wanted to get the 1000 watt motor but i talked to Chris from tnc scooters and said that i would have to weld and cut but i cant do that.

Can you give me the step by step to putting the mods for the 750 engine into my razor mx650.I also need to kno hot to install the modules too. I have no idea.
Do you just put it in or is it some long process.
