I hve had constant problems with machine the frame that was sold in this pkg has one have has 1 wheel on the carraige and is too light weight to hold the machine. I went to see about trading it in on a new one at the dealer that I bought it from and found out that what I pd 15,000 dolllars for 2.5 yrs ago is only worth 4,000 dollars trade in. Talking about getting the breath knocked out of you. Was offered a sale of a new frame for 2,200 dollors. Fuming I left only to find tha all tin lizzies are not worth anything on trade. Do not waste your money on a qubot unless you get a better frame because it will not work when the frame wears.
