My wife brought me a present yesterday... A new hitch for my son's trail-a-bike! Cut my 45 minute commute with my son down to 10 minutes! And the best part was when I dropped him off, his first comment to me was "Daddy, can you pick me up after work with your bike?" It made for an excellent workout hauling the empty trail-a-bike up Burnaby Mountain. Those things aren't light, but I got a kick out of passing another cyclist on the climb.
For those that need a new hitch for their trail-a-bike, original replacements are hard to find if you own an off brand. Trail-gator offers an "Extra Seat Post Kit" that is an excellent replacement for those. It cost my wife $40 Cdn which is a bit steep when it's available online for $19.99US. The block is 25.8mm wide which was 0.5mm wider than my trail-a-bike needed, but 5 minutes with a bolt and pair of nuts, and I had the trail-a-bike mounting tabs spread to accommodate it. My wife was also very upset with the horrible customer service she received from Cambie Cycles in Vancouver. They would not answer any of her questions. It was nice that they stocked the part I needed, but it sucks that the sales clerk could not take the time to answer my wife's questions. I do not recommend them at all.
