How does it stand in our lineup?

Providing more range, power and speed, it is an all-in-one package for your Sur-Ron. It achieves this by utilizing the extra tolerance in your stock controller. For those who already have an upgraded controller, the 21700 Molicel cells give you 22kw of real world continuous power to work with. Designed to retain drop-in functionality, there are no compromises necessary. With only a simple lid modification, you will be ready to start riding in no time!

What are the specs on the Gladiators?

The full spec sheet for all of the Gladiators can be found on each product page or you can click here!

Will The Gladiator work with my stock controller? 

As long as it is one of the 60V or 66V Gladiator options, your stock controller is completely compatible. (Your stock charger is only compatible with our 60V Gladiator options). If you are looking at one of the 72V Gladiators you will need an aftermarket controller and a 72V charger. 

What does the Plug do?

The Plug is only needed on stock controllers. The Plug bridges a connection in the unused connector and allows for full controller power to be utilized, while stopping debris from getting in. Since we aren't using that connector the Plug gives it the ability to send the extra signal that is needed. There are no drawbacks, it is just there to give stock controller users the ability to harness the full power of their stock controller.  

Can you ship a Gladiator to me in Europe?


Will I see a speed increase with the 60V Gladiator options? 

You may see a slight increase of 1-3mph but nothing significant, you will however notice that you can maintain your top speed for much longer without dealing with cut outs! To see a true increase in speed you will want to go with a 66V or 72V Gladiator. This is due to the voltage, higher voltage means higher speed!

Do I need to change anything in the Smart BMS App? What is important to know about it? 

No, you will not need to change or adjust anything within the app! It is pre-programmed for the gladiator. The only things within the app that will be accurate and significant to you are the voltage, cell group levels and the temperature. You can disregard any of the other readings. If you want to change something such as low voltage cut off you will want to do that in your controller settings!

What should my low voltage cut off be set to? (aftermarket controllers) 

For a 60V Gladiator the lowest we recommend is 46.4v which is 2.9v per cell group.

For a 66V Gladiator you will want to set it to 52.2v which is 2.9 per cell group.

For a 72V Gladiator you will want to set it to 58v which is 2.9V per cell group.

How can I change my address after placing an order?

Submitted the wrong address? No worries! Just submit a Change Order ticket here. If we haven't already shipped your items, we'll change the address and confirm with you. If we've already shipped the products out, we may still be able to change the address. Just submit the ticket and we'll contact the delivery service company on your behalf - keeping you updated the whole time.

Why is the cost for international shipping so high? 

Lithium batteries are regulated as a hazardous material as they present both chemical and electrical hazards. So due to regulations we need to follow, including having a Hazmat Certification, we are assessed extra fees that go along with shipping internationally. We incur much of the cost, but there is still some responsibility for the consumer.

Will I have to pay import tax for international orders? 

Yes, Import tax is up to the customer to pay. Since each destination will have differing costs we will have no way to determine how much it will cost during checkout!

How long does it take once shipped? 

For domestic orders you can expect to receive your package within 2-5 business days. For international orders you can expect to receive it between 7-10 business days. *It is important to note international orders can take longer than this estimated time due to the nature of the packages and each individual country's procedures. 

I have an international order and my DHL or other tracking says “on-hold”.

When a package says “on-hold’ there is usually nothing to worry about. This status indicates that it may be taking longer than expected to clear customs. If you notice an “on-hold” status lasting longer than a week without movement contact our support team. 

Can I change an order after I place it? 

Yes! In general, we always maintain as much flexibility as possible with order changes. If your order hasn't been shipped out yet, we'll always allow item changes. The main exception to this process are custom requests. We cannot offer too many changes to a custom product request for obvious reasons!
