mid drive

[michealkeatns]

So I need to be able to put a trailer being told the instep hitch that's 3 mm thick or so wouldn't fit on the back wheel of a hub motor so was hoping if anyone had any input on this , also looking into mid drive bike so I no for sure it would fit on the back quick release , best mid drive under 2.5k tops ?
Found this one what do you think
