I'm the parent of an almost 11 year old and I am very familiar with these solid color bikes. Some people may think that because these bikes are solid colors with the same colored rims that they are stolen and just being spray painted. Before making these kinds of accusations you really should look them up. These bikes are legitimate, expensive and top of the line.
As far as children of all ages riding their bikes in the streets or on the sidewalks. This has long been a topic and probably always will be. Citizens in MC complain about the kids riding BOTH in the street and on the sidewalks. It wasn't long ago when someone was complaining about kids riding on the sidewalks and that they should be riding on the street. Then there's those that complain about them riding on the street. I know that some of the younger ones have things to learn but they do try to behave. Since people aren't happy with either scenerio where would you suggest that these children ride their bikes? In my opinion, there is no good answer.
Sure, some of the kids may be rude and inconsiderate of pedestrians and vehicles, however, please don't lump all of the kids on bikes in MC into that group. So there's some problems with SOME of these kids but not all of them. They are just trying to have fun and keep busy. There are much worse and destructive things that these children could be doing. Riding bikes and doing tricks is the least of the activities that we should be worried about.
As a driver even I get irritated sometimes with kids riding in the road or darting across in front of me. However, it isn't just the kids that do that. Recently, there was an adult that did that to me and they chose to start yelling at me when I almost hit them. They were riding up to a 4 way stop intersection, in the wrong lane and had no intentions of stopping. When I turned right from the 4 way stop I came head on with this rider who was completely in the wrong. We live at a busy intersection and honestly, I see more adults ride through it everyday with no regard to the stop signs, even when there are people in cars waiting to go through the intersection.
I would suggest that everyone children and adults alike (on bikes and in cars) to just take a few extra seconds when they are riding to look around and be aware of what's going on around them. Watching for riders really is no different than being an alert driver and watching for other vehicles. Let's give most of these kids a break and not let a few disrespectful and problem kids on bikes cause us to lump all of the kids on bikes in town into one category. Again, there are much worse things the kids in MC could be doing. Maybe they can just do what they do and be a little safer about it.
