With over 5 years of hands-on experience in the industry, we understand what works, what fails, and how to build kits properly.

Every kit includes free installation. We also provide a first service checkover with minor adjustments to make sure everything stays dialled in.

Selected kits are stocked in our Australian warehouse for fast dispatch. If a kit is out of stock, express shipping takes approximately 2–3 weeks.

I slapped on the amprex 400amp 72v controller onto my fmx sur ron build. Had absolutely no clue what to expect, half the price of a ebmx x9000? Is it going to be a cheap knock off? It doesn’t preform like a x9000, thats not the point. At first was abut fiddly to tune it, after getting it dialled in it ran great. The occasional hickup here and there. But unlocking my bike’s potential for half the price of other controllers is a massive win for me. The controller preforms well, but the customer service is even better. Any issues i had were resolved asap. Value for money is absolutely unreal. -Stark Sender

I purchased a 2000W e-bike kit for my son through Amprex. There were some minor delays with a few items, but Cooper kept us updated the entire time and was always transparent about what was happening. He was extremely professional, clearly knows his products inside and out, and his communication was spot on throughout the process. Couldn’t recommend Amprex highly enough. Thanks again, Cooper.
