Free Installation

Amprex backs its riders. All batteries and controllers include free installation — no hidden costs. We also run free-install perks on select accessories during launches and milestones. Getting your bike dialed shouldn’t cost extra.

Quality

We only sell parts we would run on our own bikes. Every component we stock is the same gear we use in our in-house repairs, builds, and performance upgrades. If it’s not good enough for our personal setups, it doesn’t make it into our store.

Support

We work on these bikes every day. Our team understands the real mechanical issues riders face because we diagnose and fix them constantly. When you need help, you’re getting support from people who actually know these machines inside and out—not guesswork. We’re here to keep your bike running at its best.

Just a few of our very happy customers

Stark Sender

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

Simone

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.
