My 2020 Cube Acid Hybrid One 500 has developed a creak from the crank area when pedalling hard. A quick google seems to indicate loose motor mount bolts being the culprit so I thought I'd torque them back to spec.
I ordered this package from ebiketuning.com to remove the crank arms and lockring to get to the mounting bolts:
First of all the head of the crank puller doesn't fit through the hole at the end of the crank arm, fortuately I didn't damage anything before I figured out what was happening. After going out and buying a different puller that would fit, I then found out that the 'ebikespider' tool doesn't fit on my lockring either. A total waste of time and money and still have to cough up more money to get a tool for the lockring. Let the buyer beware!
