Thinking about getting one. I've seen a few around town, just saw one yesterday actually on the trail. I was wondering if you ever take them on the roads in traffic or do you stick to bike trails all the time. The only time I see them is on the trails,
Also, how are they going up crazy steep hill climbs when you normally would be on a small chainring ring on a bike (or out of the saddle)?
Another question: are they good for really narrow paths like sidewalks?
