The frame is custom designed by the engineering team at the 

FLX Shanghai office. It still has the iconic FLX top-tube, but with 

a new downtube and motor bracket. The dropouts are also new, 

with the disc brake caliper mounted inbetween the chainstay 

and seatstay. The rear axle still uses a 12mm Quick Release 

with 148mm Boost spacing. The frame is occupied with plenty 

of Rear Rack Bosses, Fender Bosses, and Bottle Cage Bosses to 

mount any accessory.
