Instep Quick N EZ Bike Trailer

Pros: Quick, easy, smooth ride, high visibility, nice safety features...
Cons: Pulling heavy kids in a bike trailer; some "snap" problems right out of the box

My in-laws just got my wife and I new bikes for our birthdays. Our birthdays aren't until June, but the weather's getting warmer, and since my wife's diagnosis with Multiple Sclerosis last spring, we've been looking for ways for her to stay in shape ...

Pros: Affordable
Cons: Narrow frame, lack of midline seat support, less suitable for double occupancy.

The trailer is rated for up to two passengers, but unfortunately the seat has very little support in the middle, meaning the two infants will slump towards each other like they were sitting together in a hammock. This makes for an uncomfortable ride for them, and they are much less likely to tolerate longer rides than if they each had a bucket-style seat. Also, the "5-point" harness is actually a 3-point harness for each twin with single seatbelt spanning across both twins - which further squishes them into the middle of the trailer. Other bike trailers seem to have avoided this problem.
