TECH SPECS
The XL GT-ONE Kit is the most powerful Crazy Cart kit in the world, capable of peaking over 12,000 watts.
This kit introduces our new 22kW capable controller, our new 100V battery system, and the biggest brushless motor anyone is currently offering for a Crazy Cart. We took everything we’ve learned over the years and packed it into one no-compromise kit.
It’s insanely smooth too. The XL GT-ONE uses the biggest and strongest belt setup we’ve ever fit onto a Crazy Cart, and it’s built around the same style of belt system you’d find on real vehicles. That means it can handle serious power while still feeling smooth, controlled, and reliable.
We also introduced our new 4-inch wheel hub system, which lets us run larger tires as standard and pair them with our custom-machined 60T billet wheel sprocket.
One of our favorite new features is the tool-less axle bolt release system. This makes it the first Crazy Cart kit to offer full tool-less rim changes. Bring an extra rim with you, swap it out in seconds, and keep riding without needing to carry tools around. Grab an extra rim assembly at checkout!
FAQ
Which Crazy Cart models does the XL GT-ONE Kit fit?
The PRO Kit is specifically designed for the Crazy Cart XL.
It is NOT COMPATIBLE with: Standard Crazy Cart; Crazy Cart Shift; Crazy Cart Shuffle
How fast does the XL GT-ONE actually go?
The XL GT-ONE tops out at roughly 50 mph, and it pulls hard the whole way there.
This kart has the potential to go much faster but for safety purposes we gear it to 50mph stock.
Gearing can also be adjusted by the end user but is not recommended.
Does anything ship assembled?
Yes some parts come assembled like the XL Fork system, this means that the only install you need to do is getting the fork system onto the frame.
Oh and no drilling required!
What kind of upkeep does it need?
Far less than a gas kart. No oil, no fuel.
Keep it charged, keep it dry, and check tire and drift wheel wear plus bolt and belt tension every so often. That's about it.
One heads up: with this much power, tires are what you'll go through fastest. Stock up on a few sets, or run a more docile tune if you want them to last longer.
STORE AROUND 50% CHARGE IF LEFT UNATTENDED FOR LONG PERIODS OF TIME.
Can I adjust the VESC settings myself, or is it locked?
The controller is not locked and you are able to do any tuning adjustments you'd like BUT as to not void warranty, VESC settings can only be changed with the assistance of a Tottoms team member.
Please reach out to our support team if you would like to make any changes to your controller.
Are there different speed modes?
Yes, you can easily select different modes through the included digital display!
How difficult is the install and what skill level is this aimed at?
It requires an intermediate skill level and a few basic tools. It is a very simple walkthrough with our upcoming video guide!
No Drilling Required
Warranty Information
What is covered under warranty?
We cover the full powertrain with our 6-month warranty. This includes the controller, motor, and battery, as long as no changes are made without approval from the Tottoms team.
Adjusting controller tuning, wiring, connectors, or system settings without approval may void your warranty. If there is a setting you would like adjusted, please contact us first. We are more than happy to help you make the proper changes safely.
This warranty does not cover water damage. Please note that these kits are not waterproof. Damage can occur if water enters the controller, battery, wiring, or other electrical components.
Consumable parts are not covered under warranty. This includes items such as tires, belts, chains, sprockets, brake pads, and other wear items. These parts naturally wear down with use and will need to be replaced over time.
Consumables may only be covered if they fail due to a manufacturer defect. A manufacturer defect means the part failed because of an issue with the way it was made, not because of normal wear, misuse, improper installation, water damage, crash damage, or lack of maintenance.
