Bird Zero AM Mk 3 (Boost) specification

Bird Zero AM Mk3 (Boost) in Atomic Blue
Atomic Blue Bird Zero AM Mk3 (Boost)

The original spec of my Bird Zero AM after building it up from a frame and transferring brand new bits off a 2018 Pinnacle Iroko 2.

Not all the parts are as I would wish them to be but overall this was a cost-effective way to build the bike when my employer restricts Ride2Work purchases to Evans Cycles only!

You can read more about the Bird Zero AM (Boost) on the Bird Bikes website. The Pinnacle Iroko 2 can be seen on the Evans Cycles website.
