Purchased my Jamis Boss 300 in 1995. Put a Z.A.P. Friction motor on it a couple or three years later and the CLyte 5304 this year. 800 miles since May of this year means I ride it a lot more than I used to. Unfortunately my expensive Cannondale has spent most of that time sitting on the bike rack
The Z.A.P. was, for its time, FANTASTIC. All I wanted was a "little" assist going over the bridges and into the headwinds. The problem was that after about three minutes it was addictive. With the 5304 however it is probably like switching from Marijuana to straight heroin/meth/cocaine cause I hardly remember how to pedal anymore and I spend time and money on it very much like an addiction.
