ive had this damn electric bike for almost a month now....

ive went thru 3 differnet controllers...and finnally get a controller that looks like it will work good...and I try to take the bike out today because it was 71 degrees here...and i get 2 blowouts on my back tube....

these are brand new tires and tubes...and I blew out 2 tubes at the exact same distance...

does this mean I am to heavy for back tube tire ? I weigh 260 and the bike weighs 70...so thats 330 lbs....the tubes just made a loud popping sound after about 5miles of travel each...

they are suppose to have 50-70 psi...and I had about 68 psi in them...

WTF is going on with my luck...this is ridiculous...I just want to ride the f##$@$ ing bike...
