At 12 mph I usually take over and pedal to go faster.
I was still happy with that because I could accelerate from stops faster and climb the hills around my house more easily.
The amped Gear motor runs at 20 mph unless you have the euro plugs connected. Also they upgraded me to the 22A controller w my geared motor for $20 plus the old controller. It is now a billygoat!!!! the torque is amazing. If you are running under 20 mph you need to re read the manual and disconnect the euro plugs
