You could bolt on one of the 24V 450W motor/gear reduction combos. I think it is rated at 450W with 24V and 600W at 36V.
36 Volt 600 Watt MY1020Z Gear Reduction Electric Motor with 10 Tooth Chain Sprocket and Bracket. I am considering this option myself, since I was trying to splice a 750W Currie motor to the reduction gearbox. However, the stock motor has the pinion machined into the motor shaft, plus the Currie motor shaft isn't long enough to copy the machining on the motor shaft (plus not worth the trouble).
Finished the upgrade. Decided to go with 800w 36v MY1020 motor, 11 tooth motor gear & 90 tooth axle gear #25H. Changed the speed controller to 36 and added an extra battery. Works great, gained a bit a speed but lots of torque. It has no problems going up grass hills with my 12 year old (it actually can carry me up the same hill @ 220 lbs). A bit more involved project than i was hoping for but the results are great.
Great to hear that the upgrade was successful. Using a MY1020 motor without a gearbox must have made the ATV quieter than it was with the original motor that had a gearbox. I am not sure why we did not see your posting back in November, it must have gotten buried under a lot of other postings that month. I apologize that we did not reply earlier than now.
hello I am interested in doing the same upgrade to my daughters Go-bowen Sonora 24 Volt 350 Watt pink cameo ATV. I would like to upgrade it to the 800w 36v electric motor. You mentioned that you changed the axle gear to 90 tooth. WHere did you get that part. I know I have to change the controller to 36v where can I get that too? Then just need to purchase another battery. If you can help me out in anyway to compete this project I would appreciate it. This is my first attempt to modify something like this so learning as I go. I also have a Razor MX 650 that I changed the panels on it plus put front and rear lights to make it look like a endure. If I can upgrade this one I might change the razor to a 800w motor too. Its already 36v controller so that should be a easy swap.
Here is my Razor MX 650
We carry 36 Volt 800 Watt controllers on this page: https://electricscooterparts.com/speedcontrollers36volt.html
Wow 1800w for the Mx ? I thought you had to make major mods with Welding to do that ? If not I am very I am very interested in this set up . My original plan was to up grade the Mx to 800w and take the 650 motor and put it in the Sonora atv . But making my Mx 1800w and still making the atv 650w
OK after reading all of this I have now rethought things and have a few questions on my Idea. First off I am really interested in the 1800w kit for my MX650. Since I will almost be spending the cost of the bike on the upgrade, do you have any video or specs on how fast the bike will be with these mods. I am thinking the bike being in the 30 mph range on the street. ANd I am sure the torque will be much better to push my 180 lbs up hill. Before I spend this kind of money I really want to see how the bike will perform with these mods. Before I knew about this kit everyone was saying to get 1000w motor to fit you needed to weld and cut the frame which I was not going to do to my newer MX650. So if you can guide me to anything visual on this mod I would appreciate it.
Now my second Idea is using the 650w 36v razor motor with its controller and putting it in my daughters go-bowen Sonora atv. Is there any kits available for the go bowen atv? The atv itself is great but looking to get more HP out of it so my daughter can use it a few more years and before she starts stealing my MX!!! If no kits available is it possible to put my MX650 motor and controller in the go-bowen ATV? If so then this kit even makes more sense using the two bikes I already have and making them quicker and more useful for the trails behind my house and street riding around town. MY MX is buildt to look and act like a endure. So I can even ride down the street with it and connect to other trails around town especially with a 1600w motor!!! Please advice this novice electric bike rider.
Hi, I currently have a GoBowen ATV 24V 350W and looking to make some modifications/upgrade to increase tork and possibly a bit more speed(not as important if it creates a lot more mods) Is there a 24V solution or should i look into a 36V 750W solution?
