Razor MX350 Electric Dirt Bike Upgrade to 36V or 48V

Looking to upgrade an MX350 to 36V or 48V.


Don't want this to turn into a large deal, but the current batteries need to be replaced so while at it want to upgrade.


Please let me know thoughts and suggestions..

We have helped to upgrade a lot of MX500 and MX650 dirt bikes, however, not so many MX350 and MX400 dirt bikes. We would certainly like to get started on making more MX350 and MX400 upgrade kits though.


We currently have only two MX350 and MX400 upgrade kits which are both 24 Volts and 450 Watts and 500 Watts. Here are links to them:

With a 36 Volt or 48 Volt kit, the motor power could be increased to 750, 1000, or even 1600 Watts. 


The limiting factor would be the battery pack size though since the MX350 and MX400 frames will only allow so much room for the battery pack. 


The smallest batteries that should be used with 36 or 48 Volt 750, 1000 or 1600 Watt motor are 12V 15Ah batteries which are 6" long x 3-7/8" wide x 3-3/4" high. A 36 Volt system would use three of these batteries and a 48 Volt system would use four of these batteries. Using a smaller size battery for these motors would place a strain on the batteries which could result in a lower battery lifespan. 


We do not have an MX350 or MX400 in the shop right now to check and see how much room there is for the battery pack. So if you would like to check and see if three or four 6" long x 3-7/8" wide x 3-3/4" high batteries would fit then we could take it from there with designing a more powerful kit for the MX350/MX400 series Razor dirt bikes.
