Speed switch did not need just a chicken elbow useless speed control switch size is from the controller such as the need to walk the line or replace the wiring harness with wiring harness with adjustable speed line needs to be installed (good-looking but expensive)Battery life will be reduced, because the motor battery 350W discharge capacity is relatively large especially manned starting high-speed riding or climbing 12AH battery is a little large current discharge point load 20AH. You should not install the bicycle type should be 20AHFor 350W motor running 30 kilometers, than when no change, generally will be almost 10 minutes fast!!!
I wholesale electric three wheel and Boer goat's understanding of the electric car,I told you are responsible for the motor and controller for 350W than 240W run faster.As for how fast, that depends on its motor, the same 350W motor speed is not the sameAfter switching power increases, run faster, power consumption is also large, such as running fast, a person riding up to 40 kilometers
I think there is no need to change the motor, run 30 kilometers in advance to go 10 minutes to solve the slow, safe and save the bad battery storage out of warranty period, bad to change to hundreds of piecesWant to buy a YAMAHA style fast fast the pedal motorcycle ran a handsome or Yadi motor 800W especially like 60V that super handsome or disc style and more than 10000 YAMAHA
