We were working on this bike earlier in the week at the store. It's a 1988 or 1989 Raleigh Edge. It has a 26" front wheel and a 24" rear wheel. I remember selling them when they were new at TC. They were meant to mimic trials bikes from the era, but it was really much more of a mountain bike with odd sized wheels. It did accelerate well, but I never took it off road.
This example was in exceptional shape, still sporting the original tires...which were dry rotted and we replaced them. Neat blast from the past.
