I just signed up on the forum as I recently bought a Rowbike, which uses 20" Skyway Tuffwheel II's a.k.a. "Mag" wheels. I was excited about this because my favorite bike I had as a kid in the 80's had these. I'm finding that the bike is pretty fickle where stability is concerned, from a combination of the geometries involved in the steering and the small wheels. The wheels are fitted with standard off road knobbies, I've wondered if it would help to put some road type tires on? Any opinions? I don't think anyone here would really have experience to relate, but who knows, I figured that it's worth asking. This bike is really a niche market product, not meant for serious riding over distance or in busy cities, you can't expect to maneuver quickly with it, so slowing down the steering isn't a concern, I'd rather it were less twitchy. I stay on less busy streets and large parking lots, it's for exercise and it's more fun than rowing indoors. Maybe someday I'll try to commute to work with it, someday long into the future. lol

Was going to post a picture, but apparently I'm not allowed yet. Fair enough.
