Speed Upgrade Controller – Hunter2.0（Not for Hunter 2.0S）

Speed controller upgrade

I like it. The bike is faster but I don't feel it's as quick to get up to it's top speed compared to the one that came with the bike. The one that comes with the bike gets to it's top speed and stays there. The upgrade struggles to hit top speed and has a hard time keeping it. Both with a full charge.

Definitely made it faster, but really doesn’t upgrade anything else. I know its not supposed to though. Hardest part getting some wires through the holes in the frame, maybe took 20 minutes or less to do.
