HappyDave Posted April 21 Share Posted April 21 Hello! I bought an A2 and received it 1 week ago. First day, everything was fine without any noise, but after 1 or 2 days of use some creaking noise could rarely be heard. Now, after one week of use, it has become the norm, very easy to reproduce (attached video). I have watched the "Livestream Teardown - Begode A2" from 2cells1pack YouTube channel, and looks like the screws used for the "L" pedal support don't have Loctite applied, so I think this could be the cause, what do you think? 5d0c4b42-cc64-474c-b125-270aa55eddea.mp4 Quote Link to comment Share on other sites More sharing options...

Mten4 and A2 require occasional attention to the bolts. I myself needed to pry the body apart and retighten #9 after I offered it to some mutual friends to try and noticed my tire wasn't centered with the body.

HappyDave Posted April 23 Author Share Posted April 23 I have been able to reproduce it without mounting/riding the wheel, just pushing it from the top and apply a little of force to downside. 2996d1bd-ced8-40f0-bd75-b9635853e6f2.mp4 Quote Link to comment Share on other sites More sharing options...
Paradox Posted April 23 Share Posted April 23 Almost sounds like a short. Time to get in there and check everything. 1 Quote Link to comment Share on other sites More sharing options...
Funky Posted April 23 Share Posted April 23 (edited) It sounds like cracked metal.. Over time that crack gets bigger - more noise. I would try to move/bend euc body to find the crack. (Check weld spots first.) Those cracks look like hair lines.. Also are that small. If one doesn't know what they are looking for can easily be missed. Does it make that noise, if you try to move it only holding by pedals? (Don't hold onto EUC body..) Put some force only onto pedals.. Just guessing, but by chance there isn't a crack in the pedals? Or pedal "L" brackets? Start going by where most weight is put on.. Pedals or around that part.. As something moves - it gives and makes cracking noise.

Yes, as you can see in the first video, when I apply some force with my hands onto the pedals Quote Link to comment Share on other sites More sharing options...
HappyDave Posted April 23 Author Share Posted April 23 I found somebody that just posted a video of A2 with similar creaking noise on the background. He says that all A2 creaks Quote Link to comment Share on other sites More sharing options...
Funky Posted April 23 Share Posted April 23 Well i am more happy now, that i dodged a bullet.. At some point i wanted to buy A2. I am heavier rider and it would crack way worse under my fat ass. Quote Link to comment Share on other sites More sharing options...

Yes, as you can see in the first video, when I apply some force with my hands onto the pedals Oh i didn't watch till the end.. Now i see. Pedals are cracking.. "L" brackets may be loose on axle.. You could try applying grease on pedal "rod". Maybe it is making that noise as pedals move around.. Doh second video you where moving it by body itself.. It all cracks LOL. Question - When you are riding and change riding direction like from going forwards starting to brake.. It doesn't feel like whole EUC body "moves" little bit? Like there being a play when you brake/accelerate? Like literally whole euc body falls one way, or other way before starting to go that direction? (Very little, about 1Cm, or maybe 5mm play.)

alcatraz Posted April 24 Share Posted April 24 I have this on one of my wheels. Nothing is cracked. I think the pedal rod isn't super straight so that when things flex there is some movement. Quote Link to comment Share on other sites More sharing options...
