Based on the price of the bikes, I unfortunately assumed UBCO bikes would come with great support if needed, a proper battery warranty that UBCO would actually stand by, and a battery that would last longer than my kids' cheap TEMU-level power wheels. Unfortunately, one of our two UBCO bikes' batteries died because it sat in a cozy climate-controlled garage for a few months when it was cold outside and UBCO decided it sat too long and voided the supposed 2-year warranty. This is a $1500 battery and it lasted only 16 months from purchase. Hot garbage in my opinion.
