Input:
Question: Is the floor, where the feet go soild and firm? or does it sag?
Document: Everything is even spaced so it doesn't matter where they're sitting, and it's designed very well. The seat itself has something rigid under it so they don't sag (as I've read about other models). Where their feet go doesn't have this and is a few inches lower. It's interesting how they designed it so well with so little.Top & Fabric: You can cruise with no top (as I've been doing) or easily snap the top on in seconds.

We like this bike trailer a lot. I like how easy it is to set up! So far, it has been used almost everyday for about a month with two kids (1 1/2 & 4) and is working out great, As a stroller, it isn't the best. It works fine, but I definitely prefer a double BOB because the front wheel attachment is not centered and sticks out far.
Unless you plan on carrying a wrench with you. For two parents riding together, it would be best to have an extra coupler attached to each bike. Then you could simply pop the trailer back and forth between the two bikes if someone gets tired.
Unless it comes with an entertainment system and automated dog walker, I just don't see how those high-priced models could be that much better to justify the added cost. *** UPDATE ***After several more weeks of ownership, I went back and re-read my review. Here are a few updates:1. I mistakenly said the front and back rain windows were clear. Only the front one is... the back one is solid black.2.
This trailer is great quality but the stroller handle on the back is not designed well. It is either clamped down over the back canopy flap, which means you cannot access that storage area if it is on, or it is clamped underneath the canopy flap which will put pressure on the flap when buttoned down. We live a few blocks from the beach and this is our son's transportation and what carries our beach stuff. We prop the trailer up on the two back wheels and pull it through the sand with ease!
They roll reeeeeally smoothly, and the tires look to be good quality with some nice tread. The sidewall said to inflate up to 85psi but I stuck to 70psi. There is no suspension system but it feels like the wheels themselves absorb a lot of the bumbs. The front wheel is molded rubber (non-inflatable), and has a knob-clamp so you can easily put it on or take it off.
There's just no chance of this thing turning over (as has happened with the regular stroller once or twice). The stroller handle is just okay. You have to tighten the knob-clamps fairly hard or it can slowly start getting out of alingment on the bars it's clamped onto. The cushion is rubber-like. One of the packaging straps left an indent in one spot that is fine but annoys me a little.Space: I couldn't decide if I wanted a single or double trailer.
There are weep holes in bottom pan but expect to collect water.Would not even lock a dog in it unless at least back window was open for air, so more water issues and heat issues. I would rather they get wet than bake and suffocate.Is about 22 lbs. with caster and handle, seat adds about 3lbs.
The parking brake is one thing that could be better... it's harder than it should be to enable/disable and I've found that you have to step on both sides of the bar because if you just step on the middle they might not both engage.Seats: There are three conceptual seats on this thing: a left, a right, and a center. There are two sets of shoulder straps.
Answer: yes
