I like the AliExpress frame
I look for 3 things in a frame.
1" threaded head set 180mm more or less a one piece crank and the rear drop outs and the AliExpress meets all 3 the rear drop is thick and the Electra have large rear drop... The AliExpress is very close to a Shelby but beefier... Cool1bike store has 2 sites that compete for price with each other... They play the game well but I was able to get some deals and get a $100 refund... There made in Vietnam so shipping is slow because they have to order it then ship it over here...
I'm done with AliExpress mostly carburetors and kits to tune them... It's a gold mine for that but everything else is cheaper and quicker to get here on ebay and amazon so it's not worth it... My wheel masters came in and there in wheel masters box... So there legit... But I fear wheel master has shut down and amazon bought up the remaining stock and there going to be done... You have to build a wheel from parts to get a 12ga steel wheel what a shamano 110 and I'm buying up 165mm+ forged axles when I see them... The made in USA stuff...
I plan on doing this motorized bicycle thing a while and certain things are mandatory to keep rolling
