The bike is a Phillip's Twenty with 20 inch wheels and performs as well as any other fixed gear bike I have although it does spin up a little faster and is a much more nimble bike.
I wasn't towing the trailer very far and wasn't looking at any significant hill climbs as the bike runs nearly 70 gear inches and I had not yet installed a bigger cog on the flip side for a lower gearing... it would not be my vehicle of choice for long hauls or huge loads.
I did a lot more towing last week and used my Trek 7500 as it has 24 speeds with a mtb drive with serious low gearing and skinnier tyres and this is what makes hauling large loads much easier.
This is our full mobile shop on the 6 foot BAW trailer...
This was a load of donated bikes on our 8 foot trailer and this load weighed least 275 pounds with the trailer... the mtb gearing made pulling this load up a 12% grade fairly easy although I could feel it in my legs the next day.
