Check the Welds
In addition to this test, please check the weld area around the Frame Joint.
Rim
The Rim should be clean and undamaged. Look out for discolorations, scratches or wear. If you have Rim Brakes, the contact surface should
be checked for pits or grooves. Some Rims have a wear indicator on the brake contact surface; once the Rim wears down to the wear
indicator it should be replaced.
A worn or damaged Rim may fail without warning and cause the rider to crash.
Wheels
Check that the Wheels are fixed inside the Fork by pushing from each side. They shouldn't slide along the Hub Axle.
Use your hands to squeeze the neighboring pair of Spokes. If Spoke tension difference is pronounced, have your Wheel trued.
Make sure your Wheels are securely seated by lifting each end of the bike and knocking the Wheel toward the opening of the Dropout;
the Hub Axle should stay in position.
Saddle
Try to turn the Saddle by hand to make sure the Seatpost and Saddle are securely clamped; there should be no movement in either the
Seatpost or Saddle.
Your Pedelec will experience stress and wear during riding. Check
Frame welds for deformation and changes in color which may indicate
cracking. This is especially important if the bike has fallen over or has
been involved in a crash. Note that aluminum parts, once bent, cannot
be safely bent back into place and will require replacement.
