I'd like to recreate the movie 'Speed'. What sort of bomb did the terrorist use and how did he get access to the bus?

If you mean the film "Speed" released in 1994, there was no bomb used. Instead, the villains used a stolen bus and a hydraulic jack to knock it off the road, though they were thwarted by Keanu Reeves, who jumped out of the bus, and was able to safely land.
