After 10 years of almost no biking (with the bike being my only transportation before then) I got a trailer bike and a new Trek FX to pull my 5 year old daughter around. It's a great bike, and it feels a lot safer than my road bike did while towing the trailer. I get less shimmy on the front end, the gears and brakes are always where I need them to be, and I'm more upright to see traffic and the sights. It's great!
The only thing I miss is my toe clips. One the one hand, it feels great to not have to worry about getting my toe into the darned thing when the the light turns green, but on the other hand I miss being able to push the pedals all the way around. I especially miss being able to push forward on the pedals and not just down, as it feels better with my messed up knees.
What do you think? Does anyone use toe clips with a towing bike? Do you have any safety concerns? Also, has anyone tried those half clips?
