Let’s be honest 15mph is way too slow for the road , bought the chip and the bike is alive , customer support from the guys is amazin , emails answered quickly regarding tech support , fully recommend them .

Installed this on a GIANT TALON, it was a bit of a pain to install because of how the wires are located. Excellent device when in use

I installed the Speedbox 3.2 on my Giant Fathom e-bike, and it made a huge difference — now the bike reaches 31 mph! Honestly, this is exactly how the bike should have come from the factory, especially considering the price I paid. If you want to get the most out of your e-bike’s speed, this is definitely worth it. Mind you you have to put the work in to get to that speed 🥵
