>>2052092this is motorhomo but I also think it's sort of the limit for comfort if you need to pull uphill. After all you have to mash at a certain point as you can not go arbitarily slow. Also always remember to install brakes on trailers. Either overrun brakes or better brakes with a lever that you put on the bars or both.
Anywaya if I see you haul that uphill, glance at your BB and I see a motor I'll cut you some slack and acknowledge you as a cyclehead.
