motor broke company let me upgrade

[Clubserg]

I had a 1200 watt rear ebikeling dd with a unit pack power 52 volt 20amp battery on a gary fisher tarpon 2011 mtb I put 500 miles on the 1200 motor and one day after light rain the motor froze up. gall sensor I think anyway they said send it in for a new one and I asked then if I can upgrade to the 1500 and the my said sure just pay the difference. so. they sent me the return label email and I sent it to them they sent the eng that day. so it only took 5 days total. to get my new motor and wholly crap. it's way faster. I test drive it and got to 42. and chicken out. cause nothing g was tightening down. my old too speed was 35 max unless on hill. I went right past that. I think it will go 44 or 45. I will let you know. I recommend the ebikeling brand and co from us a. easy to deal with they answer email and the phone. go people. I will buy another motor for my brothers bike from them. sergio .
