    Cruzin Cooler

    So it took me a while to test this as the problem seemed intermittent and I haven't had time to take it on long rides this is what I discovered. New battery did not solve the issue even though I initially though it did. Instead it wound up going in my son's CX450 which fit perfectly after some...

    Scooter Build Help Please

    First of all thanks to all who took the time to respond to my post and hope this helps someone else as well. I am pleased to say that my 15t motor sprocket finally arrived and I installed it on my 900W 24V motor. Definitely not without its challenges. First of all the pin that came with the new...

    Speed limiter

    Most speed limiters from Chinese scooters can be removed simply unplugging one connector from the controller. Windgoo, definitely doesn't sound American. It will be a single wire. Not familiar with your model but take a look under the deck and see if there is a single wire connector from the...

    Cruzin Cooler

    Amberwolf, I agree with your assesment so I checked through all the wiring and all seems to be in order with no loose connections which I was hoping to find. I did buy a brand new 36V 16ah battery which should be arriving in the next couple days. That hopefully will rule that out. If I have the...

    Scooter Build Help Please

    Dauntless, thanks for the input. I might not have mentioned but the 450, 750 and 900 are all 24V motors. Here is kind of a recap from what I learned from Amberwolf. I was running a 24v 450W motor with a 24V 40a controller. After switching to a bigger motor the top speed decreased because I...

These all have have identical batteries, hot off the charger and driven down the same street that has a slight hill. My son...

    Cruzin Cooler

    Sorry you are definitely correct. I forgot I have a 36V controller and a 24V motor. One of the few that I have the proper voltage controller to match the batteries. I will certainly go through the entire wiring tonight to check. I am usually pretty careful with my wiring but mistakes can be...

    Scooter Build Help Please

    Ok so I threw in the towel on the 450W motor. Didn't want to because of the speed and the fact that it had a freewheel but I couldn't ride it 5 miles on a hot day without smelling the motor cooking. That was a problem when my son wants to go on 10+ mile trips.I'm not a big guy, 5'9 and weigh...

    Cruzin Cooler

    A lot to take in but here is my update. I don't believe the problem is the batteries but I could be wrong, happens frequently. Took them out and installed them in a ezip 750 and they seemed to be working fine. Am I mistaken to think that LVC shouldn't happen on a 24V system without destroying...

    Scooter Build Help Please

    Can anyone point me to a motor that won't overheat, easy to install without fabricating a new mount? I don't want to lose speed and would like to stay at 36V if possible. I attempted to install a heatsink and fan from a computer which helps a little but not enough. It helps mostly for cooling an...

    Cruzin Cooler

    A friend gave a an old broken Cruzin Cooler 500W 50 series. Turned out the batteries and controller and throttle were toast. I replaced the old lead with 2 36V 7.8ah lithium battery packs run in parallel. I then bought a cheap 36V 500W controller and throttle with a key. Everything appeared to...

    City Coco or Fat tire Scooter Upgrade Help

    Thanks, any help would be appreciated. I am really struggling with this build as I can't find a controller that fits. I ordered one and it is too big. I can't get it to fit with the massive battery and BMS. I ordered a second controller that was supposed to be a little over 7" long which I need...

    I am running two of the packs in parallel and are 43.6V hot off the charger. Not sure what voltage your batteries are but you will need at least 36V for the motor to turn with a 36V controller.

    City Coco or Fat tire Scooter Upgrade Help

    Hello, was wondering if anyone had any experience in upgrading a City Coco Harley fat tire scooter? Currently mine goes 20mph limited. I feel like it has more to give but governed or was limited by the batteries. Cool but just too slow when my Ezip 750's and and mongoose FS fly by at 25mph. So I...

    Scooter Build Help Please

    Hi everyone was hoping for some insight on upgrading my Mongoose FS lowrider scooter. I currently installed a 36V 18ah battery pack which works great. Flat ground I hit 25mph and have logged 31mph down a hill. Sitting on the rear fender and feet on the pegs was a bit scary and wobbly at that...

    Well I added the second battery and all seems well. I have not taken it on a long ride yet but it has no issues cutting out anymore and cruises at 22mph. I know eventually the motor will give up but I will have fun in the meantime. I am just hoping that these $45 batteries can get me better...
