I replaced the wheels with smaller ones that don't turn but don't have much heel strike either. I ride or walk the bike where I need to go and pick up the unfolded bike and carry it. by picking it up fore or aft of the place where the bottom support bar attaches the frame you can adjust for heavier front or back depending on how the load is situated. Using wheels that actually turn such as Rollerblade wheels allowed it to be pushed, but the heel strike was a bigger annoyance than the few times I need to roll it. So far when I go to the grocery store I have been able to leave it unfolded and use the "Folding Shopping Basket" as my grocery cart.When I get to checkout I detach the bag, unload it and have the clerk put my groceries back in after paying. This is probably the only Brompton in Wyoming so the grocery guys are more puzzled than upset about a bike in the store. If I have to carry it a ways I can throw the saddle horn over my shoulder,,stabilize with my right hand and carry it easily for a bit. As Kell said," It is not the weight, but the awkwardness of it", so balancing it is the key. What I love about this bike is flipping the rear wheel under and parking it. My pathetic little wheels work just fine for that.
