that complete BS, i’m 15 and i got this bike completely set up in 15 minutes. and the bike’s battery can come off the bike and recharge. why would they put a disposable battery on a 500 e bike. and even though the price is low for an e bike, the bike does not feel cheap in the slightest. i feel comfortable going 30+ mph. the video instructions are perfect too. give some thought into a product before you criticize it.
