I have a Powerider Force that uses the Bewo 250w motor; bought it online from Justride in Melbourne back in early 2016 (I'm in Brisbane).
I sent it back to them after a couple of months as the motor was making a grinding/binding noise; they reckoned the motor was loose and said it likely due to extra vibration from me putting on puncture-proof tyres (Tannus Tyres - happy with these
I'm doubtful they were the source of the problem though). Since the bike came back no motor issues though, until...
A couple of weeks ago, go to pedal off and makes a cracking noise. It's gotten progressively worse.
I think it could be a broken pedal axle, or whatever part links the crank/axle inside to then drive the chainwheel. If I pedal, even with no assistance, makes cracking noise and doesn't seem to provide drive to chainwheel properly. With bike stationary and some pushing on pedals it feels "springy", whereas it used to have a solid feedback.
It doesn't seem to be the motor itself, as if I just use the throttle the bike takes off smooth & noise free.
Does anyone have info on how to best get the chainwheel off without specialised tools? Hoping to get the motor open so I can see what the actual problem is, and if it can be fixed, rather than spending $$$ on a replacement.
I have not yet tried contacting Bewo directly to see if they can provide spare parts (although a friend mentioned they might know someone near Brisbane who could fabricate small motor parts).
Thank in advance y'all
