Don't take it personally, but it would be much better if you had a website just like all the other companies selling 35A kit.
If you have a website, accept Paypal (which will give customers 180 day money back guarantee), tracking number, etc.. then people would feel a lot more comfortable purchasing from you.
Having a website will make it a lot easier, you can just post a link here if anyone is looking for a 45A controller and they can just find out what its all about.
I think it would be a good idea to have your YouTube channel and website, just like Bolton is doing.
It will be much easier for potential customers to familiarize with your product.
I'm sure there's a demand for G062 & 45A kit.
Considering how Bolton controller is always out of stock, if done right, your 45A controller & G062 will sell.
I have a feeling not just Rad Rover owners, but people who own VoltBike Yukon, Juiced RipCurrent, Sondors XS, Himiway Cruiser, MagiCycle Cruiser, etc... may also be interested.
You might be able to expand your market this way.
