Default Re: I'm still trying to wrap my head around these bikes

They don't work as well on knobby tires... But they definitly work. most of the issue is because it eats the tires way faster. However for just a quick boost to get you up the hill you won't have any issues... The wal mart off road tires are cheap and work well for the price so replacement of worn out tires shouldn't be an issue either unless you are really strapped for cash.

Biggest diwnside is that friction drives do not work when wet... At all.

Upside is that they are super easy to install and will fit almost any bike including many full sus.

Another upside is that when the roller is disengaged, the whole thing is disengaged. No chains or belts or anything else connected to your wheel... Minus the weight difference, when the roller is off, it's like the bike isn't motorized.

I will post some pictures of the one I built when I get back to my desktop, they illustrate my point a little better.
