Because it's no fun living in fear, I went ahead and did a grocery run today. Couple bottles of wine, some meat, beer, etc. This thing is a full body workout. Going to order some of the Wald wide cruiser bars for more leverage. It's actually pretty tame once you get used to it. Seems like it's actually more stable with a load.
What do we think about layback seat posts? I'd like to be a little lower and still have full extension. Worth a try?
