2013 Mongoose Fireball Street Prototype 26

Early prototype of a model that never went into production.

The Fireball Street was going to join the Fireball family of bikes at Mongoose for the 2013 model year, as a limited production model with a run of 500 bikes. Development began in Fall of 2011. The idea here was to develop a lightweight 26” BMX bike, that was durable enough for some street riding. The geometry was designed around the Cannondale Fatty Solo fork, which is light weight, and incredibly strong. I recently built it up as a BMX race bike, mostly from parts that were kicking around. Hence a few weird bits, like a camo sprocket, green seat clamp, and a pair of cranks that are half Profile and half GT. I mostly raced on Kastan’s in the early-to-mid 1990’s, so I couldn’t resist the Kastan decals and padset, given that the bike bears a striking resemblance to one of Linn’s. Here’s the spec sheet:
